The QDialog class is the base class of dialog windows.
A dialog window is a top-level window mostly used for short-term tasks and brief communications with the user. QDialogs may be modal or modeless. QDialogs can provide a return value, and they can have default buttons. QDialogs can also have a QSizeGrip in their lower-right corner, using setSizeGripEnabled().
QDialog (and any other widget which has type Qt::Dialog
) uses the parent widget slightly differently from other classes in CopperSpice. A dialog is always a top-level widget, but if it has a parent, its default location is centered on top of the parent's top-level widget (if it is not top-level itself). It will also share the parent's taskbar entry.
Use the overload of the QWidget::setParent() function to change the ownership of a QDialog widget. This function allows you to explicitly set the window flags of the reparented widget; using the overloaded function will clear the window flags specifying the window-system properties for the widget (in particular it will reset the Qt::Dialogflag).
A modal dialog is a dialog that blocks input to other visible windows in the same application. Dialogs that are used to request a file name from the user or that are used to set application preferences are usually modal. Dialogs can be application modal (the default) or window modal.
When an application modal dialog is opened, the user must finish interacting with the dialog and close it before they can access any other window in the application. Window modal dialogs only block access to the window associated with the dialog, allowing the user to continue to use other windows in an application.
The most common way to display a modal dialog is to call its exec() function. When the user closes the dialog, exec() will provide a useful return value. Typically, to get the dialog to close and return the appropriate value, we connect a default button, e.g. OK, to the accept() slot and a Cancel button to the reject() slot. Alternatively you can call the done() slot with Accepted
or Rejected
.
An alternative is to call setModal(true) or setWindowModality(), then show(). Unlike exec(), show() returns control to the caller immediately. Calling setModal(true) is especially useful for progress dialogs, where the user must have the ability to interact with the dialog, e.g. to cancel a long running operation. If you use show() and setModal(true) together to perform a long operation, you must call QApplication::processEvents() periodically during processing to enable the user to interact with the dialog. (See QProgressDialog.)
A modeless dialog is a dialog that operates independently of other windows in the same application. Find and replace dialogs in word-processors are often modeless to allow the user to interact with both the application's main window and with the dialog.
Modeless dialogs are displayed using show(), which returns control to the caller immediately.
If you invoke the show() function after hiding a dialog, the dialog will be displayed in its original position. This is because the window manager decides the position for windows that have not been explicitly placed by the programmer. To preserve the position of a dialog that has been moved by the user, save its position in your closeEvent() handler and then move the dialog to that position, before showing it again.
A dialog's default button is the button that's pressed when the user presses Enter (Return). This button is used to signify that the user accepts the dialog's settings and wants to close the dialog. Use QPushButton::setDefault(), QPushButton::isDefault() and QPushButton::autoDefault() to set and control the dialog's default button.
If the user presses the Esc key in a dialog, QDialog::reject() will be called. This will cause the window to close: The close event can not be ignored.
Extensibility is the ability to show the dialog in two ways: a partial dialog that shows the most commonly used options, and a full dialog that shows all the options. Typically an extensible dialog will initially appear as a partial dialog, but with a More toggle button. If the user presses the More button down, the dialog is expanded.
Modal dialogs are often used in situations where a return value is required, e.g. to indicate whether the user pressed OK or Cancel. A dialog can be closed by calling the accept() or the reject() slots, and exec() will return Accepted
or Rejected
as appropriate. The exec() call returns the result of the dialog. The result is also available from result() if the dialog has not been destroyed.
In order to modify your dialog's close behavior, you can reimplement the functions accept(), reject() or done(). The closeEvent() function should only be reimplemented to preserve the dialog's position or to override the standard close or reject behavior.

enum QDialog::DialogCode |
The value returned by a modal dialog.
Constant | Value | Description |

QDialog::Rejected | 0 | User rejected by pressing Esc, closing the dialog, or a cancel button located on the dialog |

Constructs a dialog with the given parent. A dialog is always a top-level widget. If it has a parent the default location is centered relative to the parent.
This dialog will share the parent's taskbar entry. The widget flags are passed to the QWidget constructor. As an example, to prevent the What's This" button in the title bar of the dialog, pass Qt::WindowTitleHint | Qt::WindowSystemMenuHint in the flags.
QDialog::~QDialog | ( | ) |
Destroys the QDialog and delets all of its children.
|
slot |
|
signal |
This signal is emitted when the dialog has been accepted either by the user or by calling accept() or done() with the QDialog::Accepted argument.
It is important to remember this signal is not emitted when hiding the dialog with hide(), setVisible(false), or deleting the dialog while it is visible.

slot |
Closes the dialog and sets the result code to result. If this dialog was shown with exec() then calling done() causes the local event loop to finish and exec() will return result. As with QWidget::close(), done() deletes the dialog if the Qt::WA_DeleteOnClose flag is set.
If the dialog is the application's main widget, the application will terminate. If the dialog is the last window closed, the QApplication::lastWindowClosed() signal is emitted.
Reimplemented from QObject::eventFilter().
|
slot |
Shows the dialog as a modal dialog, blocking until the user closes it. The method returns a DialogCode result.
If the dialog is application modal, users can not interact with any other window in the same application until they close the dialog. If the dialog is window modal, only interaction with the parent window is blocked while the dialog is open. By default, the dialog is application modal.

Instead of using this functionality, we recommend that you simply call show() or hide() on the part of the dialog that you want to use as an extension.
|
signal |
This signal is emitted when the dialog's result code has been set, either by the user or by calling done(), accept(), or reject(). This signal is not emitted when hiding the dialog with hide() or setVisible(false). This includes deleting the dialog while it is visible.

This property holds whether show() should pop up the dialog as modal or modeless.
By default this property is false and show() pops up the dialog as modeless. Setting his property to true is equivalent to setting QWidget::windowModality to application modal.
The exec() method ignores the value of this property and always pops up the dialog as modal.
