Member Enumeration Documentation

This enum type is used to describe alignment. It contains horizontal and vertical flags which can be combined to produce the required effect. The Qt::TextElideMode enum can also be used in many situations to fine-tune the appearance of aligned text.

Conflicting combinations of flags have undefined meanings.

Horizontal flags:

Qt::AlignLeft 0x0001 Aligns with the left edge.
Qt::AlignRight 0x0002 Aligns with the right edge.
Qt::AlignHCenter 0x0004 Centers horizontally in the available space.
Qt::AlignJustify 0x0008 Justifies the text in the available space.

Vertical flags:

Qt::AlignTop 0x0020 Aligns with the top.
Qt::AlignBottom 0x0040 Aligns with the bottom.
Qt::AlignVCenter 0x0080 Centers vertically in the available space.

You can use at most one horizontal and one vertical flag at a time. Qt::AlignCenter counts as both horizontal and vertical.

Two-dimensional flag:

Qt::AlignCenter AlignVCenter | AlignHCenter Centers in both dimensions.

The following enum values are useful in applications which can be run in right-to-left mode:

Qt::AlignAbsolute 0x0010If the widget's layout direction is Qt::RightToLeft (default is Qt::LeftToRight), Qt::AlignLeft refers to the right edge and Qt::AlignRight to the left edge. This is normally the desired behavior. If you want Qt::AlignLeft to always mean "left" and Qt::AlignRight to always mean "right", combine the flag with Qt::AlignAbsolute.
Qt::AlignLeadingAlignLeft Synonym for Qt::AlignLeft.
Qt::AlignTrailingAlignRight Synonym for Qt::AlignRight.

Mask flags:

Constant Value
Qt::AlignHorizontal_Mask AlignLeft | AlignRight | AlignHCenter | AlignJustify | AlignAbsolute
Qt::AlignVertical_Mask AlignTop | AlignBottom | AlignVCenter

Specifies a side of a layout item which can be anchored. This is used by QGraphicsAnchorLayout.

Constant Value Description
Qt::AnchorLeft 0 Left side of a layout item.
Qt::AnchorHorizontalCenter 1 A "virtual" side that is centered between the left and the right side of a layout item.
Qt::AnchorRight 2 Right side of a layout item.
Qt::AnchorTop 3 Top side of a layout item.
Qt::AnchorVerticalCenter 4 A "virtual" side that is centered between the top and the bottom side of a layout item.
Qt::AnchorBottom 5 Bottom side of a layout item.

This enum describes attributes that change the behavior of application-wide features. These are enabled and disabled using QCoreApplication::setAttribute(), and can be tested for with QCoreApplication::testAttribute().

Qt::AA_ImmediateWidgetCreation 0 Ensures that widgets are created as soon as they are constructed. By default, resources for widgets are allocated on demand to improve efficiency and minimize resource usage. Setting or clearing this attribute affects widgets constructed after the change. Setting it creates toplevel windows immediately. Therefore, if it is important to minimize resource consumption, do not set this attribute.
Qt::AA_MSWindowsUseDirect3DByDefault 1 This value is obsolete and has no effect.
Qt::AA_DontShowIconsInMenus 2 Actions with the Icon property will not be shown in any menus unless specifically set by the QAction::iconVisibleInMenu property. Menus that are currently open or menus already created in the native Mac OS X menubar may not pick up a change in this attribute. Changes in the QAction::iconVisibleInMenu property will always be picked up.
Qt::AA_NativeWindows 3 Ensures that widgets have native windows.
Qt::AA_DontCreateNativeWidgetSiblings 4 Ensures that siblings of native widgets stay non-native unless specifically set by the Qt::WA_NativeWindow attribute.
Qt::AA_MacPluginApplication 5 Stops Mac application from doing specific initializations which do not necessarily make sense when using CopperSpice to author a plugin. This includes avoiding loading our nib for the main menu and not taking possession of the native menu bar. Setting this attribute to true will also set the AA_DontUseNativeMenuBar attribute to true.
Qt::AA_DontUseNativeMenuBar 6 All menubars created while this attribute is set to true will not be used as a native menubar
Qt::AA_MacDontSwapCtrlAndMeta 7 By default on OS X, CopperSpice swaps the Control and Meta (Command) keys (i.e., whenever Control is pressed, CopperSpice sends Meta, and whenever Meta is pressed Control is sent). When this attribute is true, CopperSpice will not do the flip. QKeySequence::StandardShortcuts will also flip accordingly (i.e., QKeySequence::Copy will be Command+C on the keyboard regardless of the value set, though what is output for QKeySequence::toString(QKeySequence::PortableText) will be different).
Qt::AA_X11InitThreads 10 Calls XInitThreads() as part of the QApplication construction in order to make Xlib calls thread-safe. This attribute must be set before QApplication is constructed.

This enum type is used to specify the current state of the application.

Qt::ApplicationSuspended 0x00000000 Application is about to suspend. When entering this state, the application should save its state, cease all activities, and be prepared for code execution to stop. While suspended, the application can be killed at any time without further warnings (e.g. when low memory forces the OS to purge suspended applications).
Qt::ApplicationHidden 0x00000001 Application is hidden and runs in the background. This is the normal state for applications that need to do background processing, like playing music, while the user interacts with other applications. The application should free up all graphical resources when entering this state.
Qt::ApplicationInactive 0x00000002 Application is visible, but not selected to be in front. On desktop platforms, this typically means that the user activated another application. On mobile platforms, it is more common to enter this state when the OS is interrupting the user with e.g. incoming calls or SMS-messages. While in this state, consider reducing CPU-intensive tasks.
Qt::ApplicationActive 0x00000004 Application is visible and selected to be in front.

Enum contains the Arrow types.

Qt::NoArrow 0
Qt::UpArrow 1
Qt::DownArrow 2
Qt::LeftArrow 3
Qt::RightArrow 4

This enum is used by QPainter.

Qt::NoClip 0 This operation turns clipping off.
Qt::ReplaceClip 1 Replaces the current clip path/rect/region with the one supplied in the function call.
Qt::IntersectClip 2 Intersects the current clip path/rect/region with the one supplied in the function call.
Qt::UniteClip 3 Unites the current clip path/rect/region with the one supplied in the function call.

This enum describes the types of connection which can be used between signals and slots. In particular, it determines whether a particular signal is delivered to a slot immediately or queued for delivery at a later time.

Qt::AutoConnection 0 If the signal is emitted from a different thread than the receiving object, the signal is queued and is the same as Qt::QueuedConnection. Otherwise the slot is invoked directly like a Qt::DirectConnection. The type of connection is determined when the signal is emitted. default
Qt::DirectConnection 1 Slot is invoked immediately when the signal is emitted.
Qt::QueuedConnection 2 Slot is invoked when control returns to the event loop of the receiver's thread. The slot is executed in the receiver's thread.
Qt::BlockingQueuedConnection 4 Same as Qt::QueuedConnection except the current thread blocks until the slot returns. Must only be used when the sender and receiver are in different threads. Violating this rule can cause a deadlock.
Qt::UniqueConnection 0x80Same as Qt::AutoConnection, however redundant connections are ignored

This enum type defines the various policies a widget can have with respect to showing a context menu.

Qt::NoContextMenu 0 Widget does not feature a context menu context menu handling is deferred to the widget's parent.
Qt::DefaultContextMenu 1 QWidget::contextMenuEvent() handler is called
Qt::ActionsContextMenu 2 Displays its QWidget::actions() as context menu.
Qt::CustomContextMenu 3 Emits the QWidget::customContextMenuRequested() signal.
Qt::PreventContextMenu 4 Widget does not feature a context menu and in contrast to NoContextMenu, the handling is not deferred to the widget's parent. This means that all right mouse button events are guaranteed to be delivered to the widget itself through mousePressEvent(), and mouseReleaseEvent().

This enum specifies the coordinate system.

Qt::DeviceCoordinates 0 Coordinates are relative to the upper-left corner of the object's paint device.
Qt::LogicalCoordinates 1 Coordinates are relative to the upper-left corner of the object.
enum Qt::Corner

This enum type specifies a corner in a rectangle:

Qt::TopLeftCorner0x00000Top-left corner of the rectangle.
Qt::TopRightCorner0x00001Top-right corner of the rectangle.
Qt::BottomLeftCorner0x00002Bottom-left corner of the rectangle.
Qt::BottomRightCorner0x00003Bottom-right corner of the rectangle.

This enum describes the movement style available to text cursors. The options are:

Qt::LogicalMoveStyle0Within a left-to-right text block, decrease cursor position when pressing left arrow key, increase cursor position when pressing the right arrow key. If the text block is right-to-left, the opposite behavior applies.
Qt::VisualMoveStyle1Pressing the left arrow key will always cause the cursor to move left, regardless of the text's writing direction. Pressing the right arrow key will always cause the cursor to move right.

This enum type defines the various cursors which can be used. The standard arrow cursor is the default for widgets in a normal state.

Qt::ArrowCursor0 The standard arrow cursor.
Qt::UpArrowCursor1 An arrow pointing upwards toward the top of the screen.
Qt::CrossCursor2 A crosshair cursor, typically used to help the user accurately select a point on the screen.
Qt::WaitCursor3 An hourglass or watch cursor, usually shown during operations that prevent the user from interacting with the application.

For ISODate formats, each Y, M and D represents a single digit of the year, month and day used to specify the date. Each H, M and S represents a single digit of the hour, minute and second used to specify the time. The presence of a literal T character is used to separate the date and time when both are specified.

This enum is a list of the days of the week.

This enum can be used to specify event priorities.

Qt::HighEventPriority1Events with this priority are sent before events with NormalEventPriority or LowEventPriority.
Qt::NormalEventPriority0Events with this priority are sent after events with HighEventPriority, but before events with LowEventPriority.
Qt::LowEventPriority-1Events with this priority are sent after events with HighEventPriority or NormalEventPriority.

These values are provided for convenience since event priorities can be any value between INT_MAX and INT_MIN, inclusive. For example, you can define custom priorities as being relative to each other.

enum CustomEventPriority
// An important event
ImportantEventPriority = Qt::HighEventPriority,
// A more important event
MoreImportantEventPriority = ImportantEventPriority + 1,
// A critical event
CriticalEventPriority = 100 * MoreImportantEventPriority,
// Not that important
StatusEventPriority = Qt::LowEventPriority,
// These are less important than Status events
IdleProcessingDoneEventPriority = StatusEventPriority - 1

Specifies which method should be used to fill the paths and polygons.

Qt::OddEvenFill 0Specifies that the region is filled using the odd even fill rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape, and count the number of intersections. If the number of intersections is an odd number, the point is inside the shape. This mode is the default.
Qt::WindingFill 1Specifies that the region is filled using the non zero winding rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape. Determine whether the direction of the line at each intersection point is up or down. The winding number is determined by summing the direction of each intersection. If the number is non zero, the point is inside the shape. This fill mode can also in most cases be considered as the intersection of closed shapes.

Describes options which are used when finding children of a QObject.

Qt::FindDirectChildrenOnly 0x0 Looks only at the direct children of the object
Qt::FindChildrenRecursively 0x1 Looks at all children of the object (recursive search)

This enum type defines the various policies a widget can have with respect to acquiring keyboard focus.

Qt::TabFocus 0x1 Widget accepts focus by tabbing.
Qt::ClickFocus 0x2 Widget accepts focus by clicking.
Qt::StrongFocus TabFocus |
ClickFocus |
Accepts focus by both tabbing and clicking. On Mac OS X this will also be indicate that the widget accepts tab focus when in 'Text/List focus mode'.
Qt::WheelFocus StrongFocus |
Similar to Qt::StrongFocus plus the widget accepts focus by using the mouse wheel.
Qt::NoFocus 0 Does not accept focus

This enum specifies why the focus changed. It will be passed through QWidget::setFocus and can be retrieved in the QFocusEvent sent to the widget upon focus change.

Qt::MouseFocusReason0A mouse action occurred.
Qt::TabFocusReason1The Tab key was pressed.
Qt::BacktabFocusReason2A Backtab occurred. The input for this may include the Shift or Control keys; e.g. Shift+Tab.
Qt::ActiveWindowFocusReason3The window system made this window either active or inactive.
Qt::PopupFocusReason4The application opened/closed a pop-up that grabbed/released the keyboard focus.
Qt::ShortcutFocusReason5The user typed a label's buddy shortcut
Qt::MenuBarFocusReason6The menu bar took focus.
Qt::OtherFocusReason7Another reason, usually application-specific.

This enum type describes additional flags that can be used when subscribing to a gesture.

Qt::DontStartGestureOnChildren 0x01 By default gestures can start on the widget or over any of its children. Use this flag to disable this and allow a gesture to start on the widget only.
Qt::ReceivePartialGestures 0x02 Allows any ignored gesture events to be propagated to parent widgets which have specified this hint. By default only gestures that are in the Qt::GestureStarted state are propagated and the widget always gets the full gesture sequence starting with a gesture in the Qt::GestureStarted state and ending with a gesture in the Qt::GestureFinished or Qt::GestureCanceled states.
Qt::IgnoredGesturesPropagateToParent 0x04 This flag allows you to fine-tune gesture event propagation. By setting the flag when QGraphicsobject::grabGesture() "grabbing" a gesture all ignored partial gestures will propagate to their parent items.

Qt::OrderedAlphaDither0x00000004A faster, more ordered dither.
Qt::DiffuseAlphaDither0x00000008A high-quality dither.

Color matching versus dithering preference:

Qt::PreferDither0x00000040(default when converting to a pixmap) - Always dither 32-bit images when the image is converted to 8 bits.
Qt::AvoidDither0x00000080(default when converting for the purpose of saving to file) - Dither 32-bit images only if the image has more than 256 colors and it is being converted to 8 bits.
Qt::NoOpaqueDetection0x00000100Do not check whether the image contains non-opaque pixels. Use this if you know that the image is semi-transparent and you want to avoid the overhead of checking the pixels in the image until a non-opaque pixel is found, or if you want the pixmap to retain an alpha channel for some other reason. If the image has no alpha channel this flag has no effect.

Do not do any format conversions on the image. Can be useful when converting a QImage to a QPixmap for a one-time rendering operation for example.

This enum is used for multilingual input.

Qt::ImhNone0x0No hints.

Flags that alter the behavior:

Qt::ImhHiddenText0x1Characters should be hidden, as is typically used when entering passwords. This is automatically set when setting QLineEdit::echoMode to Password.
Qt::ImhNoAutoUppercase0x2The input method should not try to automatically switch to upper case when a sentence ends.
Qt::ImhPreferNumbers0x4Numbers are preferred (but not required).
Qt::ImhPreferUppercase0x8Upper case letters are preferred (but not required).
Qt::ImhPreferLowercase0x10Lower case letters are preferred (but not required).
Qt::ImhNoPredictiveText0x20Do not use predictive text (i.e. dictionary lookup) while typing.

Flags that restrict input (exclusive flags):

Qt::ImhDigitsOnly0x10000Only digits are allowed.
Qt::ImhFormattedNumbersOnly0x20000Only number input is allowed. This includes decimal point and minus sign.
Qt::ImhUppercaseOnly0x40000Only upper case letter input is allowed.
Qt::ImhLowercaseOnly0x80000Only lower case letter input is allowed.
Qt::ImhDialableCharactersOnly0x100000Only characters suitable for phone dialing are allowed.
Qt::ImhEmailCharactersOnly0x200000Only characters suitable for email addresses are allowed.
Qt::ImhUrlCharactersOnly0x400000Only characters suitable for URLs are allowed.


Qt::ImhExclusiveInputMask0xffff0000 This mask yields nonzero if any of the exclusive flags are used.

If several exclusive flags are OR'ed together, the resulting character set will consist of the union of the specified sets. For instance specifying ImhNumbersOnly and ImhUppercaseOnly would yield a set consisting of numbers and uppercase letters.

The timer type indicates how accurate a timer can be.

On UNIX (including Linux, macOS, and iOS), CopperSpice will keep millisecond accuracy for Qt::PreciseTimer. For Qt::CoarseTimer, the interval will be adjusted up to 5% to align the timer with other timers that are expected to fire at or around the same time. The objective is to make most timers wake up at the same time, thereby reducing CPU wakeups and power consumption.

On Windows the Multimedia timer will be used (if available) for Qt::PreciseTimer and normal Windows timers for Qt::CoarseTimer and Qt::VeryCoarseTimer.

On all platforms the interval for Qt::VeryCoarseTimer is rounded to the nearest full second (e.g. an interval of 23500ms will be rounded to 24000ms, and 20300ms to 20000ms).

Qt::PreciseTimer 0 Precise timers try to keep millisecond accuracy
Qt::CoarseTimer 1 Coarse timers try to keep accuracy within 5% of the desired interval
Qt::VeryCoarseTimer 2 Very coarse timers only keep full second accuracy

Qt::WA_KeyboardFocusChange77Set on a toplevel window when the users changes focus with the keyboard (tab, backtab, or shortcut).
Qt::WA_KeyCompression33Enables key event compression if set, and disables it if not set. By default key compression is off, so widgets receive one key press event for each key press (or more, since autorepeat is usually on). If you turn it on and your program does not keep up with key input, CopperSpice may try to compress key events so that more than one character can be processed in each event. For example, a word processor widget might receive 2, 3 or more characters in each QKeyEvent::text(), if the layout recalculation takes too long for the CPU. If a widget supports multiple character unicode input, it is always safe to turn the compression on. CopperSpice performs key event compression only for printable characters. Qt::Modifier keys, cursor movement keys, function keys and miscellaneous action keys (e.g. Escape, Enter, Backspace, PrintScreen) will stop key event compression, even if there are more compressible key events available. Platforms other than Mac and X11 do not support this compression, in which case turning it on will have no effect. This is set/cleared by the widget's author.
Qt::WA_LayoutOnEntireRect48Indicates that the widget wants QLayout to operate on the entire QWidget::rect(), not only on QWidget::contentsRect(). This is set by the widget's author.
Qt::WA_LayoutUsesWidgetRect92Ignore the layout item rect from the style when laying out this widget with QLayout. This makes a difference in QMacStyle for some widgets.
Qt::WA_MacNoClickThrough12When a widget that has this attribute set is clicked, and its window is inactive, the click will make the window active but will not be seen by the widget. Typical use of this attribute is on widgets with "destructive" actions, such as a "Delete" button. WA_MacNoClickThrough also applies to all child widgets of the widget that has it set.
Qt::WA_MacOpaqueSizeGrip85Indicates that the native Carbon size grip should be opaque instead of transparent (the default). This attribute is only applicable to Mac OS X and is set by the widget's author.
Qt::WA_MacShowFocusRect88Indicates that this widget should get a QFocusFrame around it. Some widgets draw their own focus halo regardless of this attribute. Not that the QWidget::focusPolicy also plays the main role in whether something is given focus or not, this only controls whether or not this gets the focus frame. This attribute is only applicable to Mac OS X.
Qt::WA_MacNormalSize89Indicates the widget should have the normal size for widgets in Mac OS X. This attribute is only applicable to Mac OS X.
Qt::WA_MacSmallSize90Indicates the widget should have the small size for widgets in Mac OS X. This attribute is only applicable to Mac OS X.
Qt::WA_MacMiniSize91Indicates the widget should have the mini size for widgets in Mac OS X. This attribute is only applicable to Mac OS X.
Qt::WA_MacVariableSize102Indicates the widget can choose between alternative sizes for widgets to avoid clipping. This attribute is only applicable to Mac OS X.
Qt::WA_MacBrushedMetal46Indicates the widget should be drawn in the brushed metal style as supported by the windowing system. This attribute is only applicable to Mac OS X.
Qt::WA_Mapped11Indicates the widget is mapped on screen./td>
Qt::WA_MouseNoMask71Makes the widget receive mouse events for the entire widget regardless of the currently set mask, overriding QWidget::setMask(). This is not applicable for top-level windows.
Qt::WA_MouseTracking2Indicates that the widget has mouse tracking enabled. See QWidget::mouseTracking.
Qt::WA_Moved43Indicates that the widget has an explicit position. This is set/cleared by QWidget::move() and by QWidget::setGeometry().
Qt::WA_MSWindowsUseDirect3D94This value is obsolete and has no effect.
Qt::WA_NoChildEventsForParent58Indicates that the widget does not want ChildAdded or ChildRemoved events sent to its parent. This is rarely necessary but can help to avoid automatic insertion widgets like splitters and layouts. This is set by a widget's author.
Qt::WA_NoChildEventsFromChildren39Indicates that the widget does not want to receive ChildAdded or ChildRemoved events sent from its children. This is set by a widget's author.
Qt::WA_NoMouseReplay54Used for pop-up widgets. Indicates that the most recent mouse press event should not be replayed when the pop-up widget closes. The flag is set by the widget's author and cleared by the every time the widget receives a new mouse event.
Qt::WA_NoMousePropagation73Prohibits mouse events from being propagated to the widget's parent. This attribute is disabled by default.
Qt::WA_TransparentForMouseEvents51When enabled, this attribute disables the delivery of mouse events to the widget and its children. Mouse events are delivered to other widgets as if the widget and its children were not present in the widget hierarchy; mouse clicks and other events effectively "pass through" them. This attribute is disabled by default.
Qt::WA_NoSystemBackground9Indicates that the widget has no background, i.e. when the widget receives paint events, the background is not automatically repainted. Unlike WA_OpaquePaintEvent, newly exposed areas are never filled with the background (e.g., after showing a window for the first time the user can see "through" it until the application processes the paint events). This flag is set or cleared by the widget's author.
Qt::WA_OpaquePaintEvent4Indicates that the widget paints all its pixels when it receives a paint event. Thus, it is not required for operations like updating, resizing, scrolling and focus changes to erase the widget before generating paint events. The use of WA_OpaquePaintEvent provides a small optimization by helping to reduce flicker on systems that do not support double buffering and avoiding computational cycles necessary to erase the background prior to painting. Unlike WA_NoSystemBackground, WA_OpaquePaintEvent makes an effort to avoid transparent window backgrounds. This flag is set or cleared by the widget's author.
Qt::WA_OutsideWSRange49Indicates that the widget is outside the valid range of the window system's coordinate system. A widget outside the valid range can not be mapped on screen.
Qt::WA_PaintOnScreen8Indicates that the widget wants to draw directly onto the screen. Widgets with this attribute set do not participate in composition management, i.e. they can not be semi-transparent or shine through semi-transparent overlapping widgets. This flag is only supported on X11 and it disables double buffering. On Embedded Linux, the flag only works when set on a top-level widget and it relies on support from the active screen driver. This flag is set or cleared by the widget's author. To render outside of the CopperSpice paint system, If you require native painting primitives, you need to reimplement QWidget::paintEngine() to return 0 and set this flag.
Qt::WA_PaintOutsidePaintEvent13Makes it possible to use QPainter to paint on the widget outside paintEvent(). This flag is not supported on Windows, Mac OS X or Embedded Linux.
Qt::WA_PaintUnclipped52Makes all painters operating on this widget unclipped. Children of this widget or other widgets in front of it do not clip the area the painter can paint on. This flag is only supported for widgets with the WA_PaintOnScreen flag set. The preferred way to do this in a cross platform way is to create a transparent widget that lies in front of the other widgets.
Qt::WA_PendingMoveEvent34Indicates that a move event is pending, e.g., when a hidden widget was moved.
Qt::WA_PendingResizeEvent35Indicates that a resize event is pending, e.g., when a hidden widget was resized.
Qt::WA_QuitOnClose76Instructs CopperSpice to quit the application when the last widget with the attribute set has accepted closeEvent(). This behavior can be modified with the QApplication::quitOnLastWindowClosed property. By default this attribute is set for all widgets of type Qt::Window.
Qt::WA_Resized42Indicates that the widget has an explicit size. This flag is set or cleared by QWidget::resize() and QWidget::setGeometry().
Qt::WA_RightToLeft56Indicates that the layout direction for the widget is right to left.
Qt::WA_SetCursor38Indicates that the widget has a cursor of its own. This flag is set or cleared by QWidget::setCursor() and QWidget::unsetCursor().
Qt::WA_SetFont37Indicates that the widget has a font of its own. This flag is set or cleared by QWidget::setFont().
Qt::WA_SetPalette36Indicates that the widget has a palette of its own. This flag is set or cleared by QWidget::setPalette().
Qt::WA_SetStyle86Indicates that the widget has a style of its own. This flag is set or cleared by QWidget::setStyle().
Qt::WA_ShowModal70This attribute has been deprecated. Use QWidget::windowModality instead.
Qt::WA_StaticContents5Indicates that the widget contents are north-west aligned and static. On resize, such a widget will receive paint events only for parts of itself that are newly visible. This flag is set or cleared by the widget's author.
Qt::WA_StyleSheet97Indicates that the widget is styled using a style sheet.
Qt::WA_TranslucentBackground120Indicates that the widget should have a translucent background, i.e., any non-opaque regions of the widgets will be translucent because the widget will have an alpha channel. Setting this flag causes WA_NoSystemBackground to be set. On Windows the widget also needs the Qt::FramelessWindowHint window flag to be set. This flag is set or cleared by the widget's owner.
Qt::WA_UnderMouse1Indicates that the widget is under the mouse cursor. The value is not updated correctly during drag and drop operations. There is also a getter function, QWidget::underMouse().
Qt::WA_UpdatesDisabled10Indicates that updates are blocked (including the system background).
This flag must never be set or cleared by the widget's author.
Qt::WA_WindowModified41Indicates that the window is marked as modified. On some platforms this flag will do nothing, on others (including Mac OS X and Windows) the window will take a modified appearance. This flag is set or cleared by QWidget::setWindowModified().
Qt::WA_WindowPropagation80Makes a toplevel window inherit font and palette from its parent.
Qt::WA_MacAlwaysShowToolWindow96On Mac OS X, show the tool window even when the application is not active. By default, all tool windows are hidden when the application is inactive.
Qt::WA_SetLocale87Indicates the locale should be taken into consideration in the widget.
Qt::WA_StyledBackground93Indicates the widget should be drawn using a styled background.
Qt::WA_ShowWithoutActivating98Show the widget without making it active.
Qt::WA_NativeWindow100Indicates that a native window is created for the widget. Enabling this flag will also force a native window for the widget's ancestors unless Qt::WA_DontCreateNativeAncestors is set.
Qt::WA_DontCreateNativeAncestors101Indicates that the widget's ancestors are kept non-native even though the widget itself is native.
Qt::WA_X11NetWmWindowTypeDesktop104Adds _NET_WM_WINDOW_TYPE_DESKTOP to the window's _NET_WM_WINDOW_TYPE X11 window property. Refer to for more details. This attribute has no effect on non-X11 platforms.

Qt::WA_MacFrameworkScaled117Enables resolution independence aware mode on Mac when using Carbon. This attribute has no effect on Cocoa. The attribute is off by default and can be enabled on a per-window basis.
Qt::WA_AcceptTouchEvents121Allows touch events (see QTouchEvent) to be sent to the widget. Must be set on all widgets that can handle touch events. Without this attribute set, events from a touch device will be sent as mouse events.
Qt::WA_TouchPadAcceptSingleTouchEvents123Allows touchpad single touch events to be sent to the widget.
Qt::WA_MergeSoftkeys124Allows widget to merge softkeys with parent widget, i.e. widget can set only one softkeys and request softkey implementation to take rest of the softkeys from the parent. Note parents are traversed until WA_MergeSoftkeys is not set. Refer to Qt::WA_MergeSoftkeysRecursively.
Qt::WA_MergeSoftkeysRecursively125Allows widget to merge softkeys recursively with all parents. If this attribute is set, the widget parents are traversed until window boundary (widget without parent or dialog) is found.
Qt::WA_X11DoNotAcceptFocus132Asks the window manager to not give focus to this top level window. This attribute has no effect on non-X11 platforms.

Qt::WA_MacNoShadow134This attribute disables drop shadows for this top level window. Only affects Cocoa builds of CopperSpice for OS X.

This enum is used to describe parts of a window frame. It is returned by QGraphicsWidget::windowFrameSectionAt() to describe what section of the window frame is under the mouse.

See also
QGraphicsWidget::windowFrameEvent(), QGraphicsWidget::paintWindowFrame(), QGraphicsWidget::windowFrameSectionAt()

This enum specifies the behavior of a modal window. A modal window is one that blocks input to other windows. Windows which are children of a modal window are not blocked.

The values are:

Qt::NonModal 0 The window is not modal and does not block input to other windows.
Qt::WindowModal 1 The window is modal to a single window hierarchy and blocks input to its parent window, all grandparent windows, and all siblings of its parent and grandparent windows.
Qt::ApplicationModal 2 The window is modal to the application and blocks input to all windows.
See also
QWidget::windowModality, QDialog

This enum type is used to specify the current state of a top-level window. The states are as follows.

Qt::WindowNoState0x00000000 Has no state set (in normal state).
Qt::WindowMinimized0x00000001 Minimized (i.e. iconified).
Qt::WindowMaximized0x00000002 Maximized with a frame around it.
Qt::WindowFullScreen0x00000004 Window fills the entire screen without any frame around it.
Qt::WindowActive0x00000008 Window is the active window, t has keyboard focus.

This enum type is used to specify various window-system properties for the widget. They are fairly unusual but necessary in a few cases. Some of these flags depend on whether the underlying window manager supports them.

The main types are:

Qt::Widget0x00000000Default type for QWidget. Widgets of this type are child widgets if they have a parent and independent windows if they have no parent. Refer to Qt::Window and Qt::SubWindow.
Qt::Window0x00000001Indicates the widget is a window, usually with a window system frame and a title bar, irrespective of whether the widget has a parent or not. It is not possible to unset this flag if the widget does not have a parent.
Qt::Dialog0x00000002 | WindowIndicates the widget is a window which should be decorated as a dialog where typically no maximize or minimize buttons appear in the title bar. This is the default type for QDialog. To use as a modal dialog it should be launched from another window or have a parent and be used with the QWidget::windowModality property. If you make it modal, the dialog will prevent other top-level windows in the application from getting any input. We refer to a top-level window that has a parent as a secondary window.
Qt::Sheet0x00000004 | WindowIndicates the window is a Macintosh sheet. Since using a sheet implies window modality, the recommended way is to use QWidget::setWindowModality() or QDialog::open(), instead.
Qt::Drawer0x00000006 | WindowIndicates the widget is a Macintosh drawer.
Qt::Popup0x00000008 | WindowIndicates the widget is a pop-up top-level window, i.e. that it is modal, but has a window system frame appropriate for pop-up menus.
Qt::Tool0x0000000a | WindowIndicates the widget is a tool window. A tool window is often a small window with a smaller than usual title bar and decoration, typically used for collections of tool buttons. If there is a parent the tool window will always be kept on top. If there is not a parent, consider using Qt::WindowStaysOnTopHint. If the window system supports it a tool window can be decorated with a somewhat lighter frame and can be combined with Qt::FramelessWindowHint. On Mac OS X, tool windows correspond to the Floating class of windows. This means the window lives a level above normal windows and you can not put a normal window on top of it. By default tool windows will disappear when the application is inactive. This can be controlled by the Qt::WA_MacAlwaysShowToolWindow attribute.
Qt::ToolTip0x0000000c | Window Indicates the widget is a tooltip, used internally to implement tooltips.
Qt::SplashScreen 0x0000000e | WindowIndicates the window is a splash screen, default type for QSplashScreen.
Qt::Desktop0x00000010 | Window Indicates this widget is the desktop, the type for QDesktopWidget.
Qt::SubWindow0x00000012 Indicates this widget is a sub-window, such as a QMdiSubWindow widget.

There are also a number of flags which you can use to customize the appearance of top-level windows. These have no effect on other windows:

Qt::MSWindowsFixedSizeDialogHint 0x00000100Gives the window a thin dialog border on Windows. This style is traditionally used for fixed-size dialogs.
Qt::MSWindowsOwnDC0x00000200Gives the window its own display context on Windows.
Qt::X11BypassWindowManagerHint0x00000400 Bypass the window manager completely. This results in a borderless window that is not managed at all (i.e., no keyboard input unless you call QWidget::activateWindow() manually).
Qt::FramelessWindowHint0x00000800 Produces a borderless window. The user can not move or resize a borderless window via the window system. On X11, the result of the flag is dependent on the window manager and its ability to understand Motif and/or NETWM hints. Most existing modern window managers can handle this.

The CustomizeWindowHint flag is used to enable customization of the window controls. This flag must be set to allow the WindowTitleHint, WindowSystemMenuHint, WindowMinimizeButtonHint, WindowMaximizeButtonHint and WindowCloseButtonHint flags to be changed.

Qt::CustomizeWindowHint0x02000000Turns off the default window title hints.
Qt::WindowTitleHint0x00001000Gives the window a title bar.
Qt::WindowSystemMenuHint0x00002000Adds a window system menu, and possibly a close button (for example on Mac). If you need to hide or show a close button, it is more portable to use WindowCloseButtonHint.
Qt::WindowMinimizeButtonHint 0x00004000 Adds a minimize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt::WindowMaximizeButtonHint0x00008000Adds a maximize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt::WindowMinMaxButtonsHint WindowMinimizeButtonHint |
Adds a minimize and a maximize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt::WindowCloseButtonHint0x08000000Adds a close button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt::WindowContextHelpButtonHint0x00010000Adds a context help button to dialogs. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt::MacWindowToolBarButtonHint0x10000000On Mac OS X, adds the oblong button which is on the top right of windows which have toolbars.
Qt::BypassGraphicsProxyWidget0x20000000Prevents the window and its children from automatically embedding themselves into a QGraphicsProxyWidget if the parent widget is already embedded. You can set this flag if you want your widget to always be a toplevel widget on the desktop, regardless of whether the parent widget is embedded in a scene or not.
Qt::WindowStaysOnTopHint0x00040000Informs the window system that the window should stay on top of all other windows. On some window managers for X11 you also have to pass Qt::X11BypassWindowManagerHint for this flag to work correctly.
Qt::WindowStaysOnBottomHint0x04000000Informs the window system that the window should stay on bottom of all other windows. On X11 this hint will work only in window managers that support _NET_WM_STATE_BELOW atom. If a window always on the bottom has a parent, the parent will also be left on the bottom. This window hint is currently not implemented for Mac OS X.
Qt::WindowType_Mask0x000000ffA mask for extracting the window type part of the window flags.

Method Documentation

QString Qt::convertFromPlainText ( const QString plain,
WhiteSpaceMode  mode = WhiteSpacePre 

Converts the plain text string plain to an HTML formatted paragraph while preserving most of its look. The value for mode defines how whitespace is handled.

This method is defined in the QTextDocument header file.

See also
QString8::toHtmlEscaped(), mightBeRichText()
bool Qt::mightBeRichText ( const QString text)

Returns true if the string text is likely to be rich text, otherwise returns false. This method uses a fast and therefore simple heuristic. It mainly checks whether there is something that looks like a tag before the first line break. Although the result may be correct for common cases, there is no guarantee.

This method is defined in the QTextDocument header file.
