Detailed Description

The QHeaderView class provides headers for item views. A header can appear vertically or horizontally. This class is used to display the headers in item view classes like QTableView and QTreeView.

The header gets the data for each section from the model using the QAbstractItemModel::headerData() function. You can set the data by using QAbstractItemModel::setHeaderData(). Each header has an orientation() and a number of sections, given by the count() function. A section refers to a part of the header, either a row or a column, depending on the orientation.

Sections can be moved and resized using moveSection() and resizeSection(). They can also be hidden and shown with hideSection() and showSection(). Each section of a header is described by a section ID, specified by its section, and can be located at a particular visualIndex() in the header. A section can have a sort indicator set with setSortIndicator(), this indicates whether the items in the associated item view will be sorted in the order given by the section.

For a horizontal header the section is equivalent to a column in the model, and for a vertical header the section is equivalent to a row in the model.

Moving Header Sections

A header can be fixed in place or made movable with setSectionsMovable(). It can be made clickable with setSectionsClickable() and has resizing behavior in accordance with setSectionResizeMode(). A header will emit sectionMoved() if the user moves a section, sectionResized() if the user resizes a section, and sectionClicked() as well as sectionHandleDoubleClicked() in response to mouse clicks. A header will also emit sectionCountChanged().

You can identify a section using the logicalIndex() and logicalIndexAt() functions, or by its index position, using the visualIndex() and visualIndexAt() functions. The visual index will change if a section is moved, but the logical index will not change.

Double-clicking on a header to resize a section only applies for visible rows.

Appearance

QTableWidget and QTableView create default headers. If you want the headers to be visible you can use setVisible(). Each header renders the data for each section itself and does not rely on a delegate. As a result, calling a header's setItemDelegate() method will have no effect.

Not all item data roles will have an effect on a QHeaderView. If you need to draw other roles, you can subclass QHeaderView and reimplement paintEvent(). QHeaderView respects the following item data roles: Qt::TextAlignmentRole, Qt::DisplayRole, Qt::FontRole, Qt::DecorationRole, Qt::ForegroundRole, and Qt::BackgroundRole.

Member Enumeration Documentation

enum QHeaderView::ResizeMode

The resize mode specifies the behavior of the header sections. It can be set on the entire header view or on individual sections using setSectionResizeMode().

Constant	Value	Description
`QHeaderView::Interactive`	`0`	The user can resize the section. The section can also be resized programmatically using resizeSection(). The section size defaults to defaultSectionSize. (Refer to cascadingSectionResizes.)
`QHeaderView::Fixed`	`2`	The user can not resize the section. The section can only be resized programmatically using resizeSection(). The section size defaults to defaultSectionSize.
`QHeaderView::Stretch`	`1`	QHeaderView will automatically resize the section to fill the available space. The size can not be changed by the user or programmatically.
`QHeaderView::ResizeToContents`	`3`	QHeaderView will automatically resize the section to its optimal size based on the contents of the entire column or row. The size can not be changed by the user or programmatically.

The following value is obsolete.

Constant	Value	Description
`QHeaderView::Custom`	`2`	Use Fixed instead.

void QHeaderView::scrollContentsBy	(	int	dx,
		int	dy
	)

overrideprotectedvirtual

This virtual handler is called when the scroll bars are moved by dx, dy, and consequently the viewport's contents should be scrolled accordingly.

The default implementation simply calls update() on the entire viewport(). Subclasses can reimplement this handler for optimization purposes, or as with QScrollArea to move a contents widget. The parameters dx and dy are there for convenience, so that the class knows how much should be scrolled. You may ignore these values and scroll directly to the position the scroll bars indicate.

Calling this method in order to scroll programmatically is an error, use the scroll bars instead (e.g. by calling QScrollBar::setValue() directly).

Reimplemented from QAbstractScrollArea::scrollContentsBy()

void QHeaderView::scrollTo	(	const QModelIndex &	index,
		ScrollHint	hint
	)

overrideprotectedvirtual

Scrolls the view if necessary to ensure that the item at index is visible. The view will try to position the item according to the given hint.

Implements QAbstractItemView::scrollTo()

If only one section is removed logicalFirst and logicalLast will be the same.

void QHeaderView::setResizeContentsPrecision ( int precision )

Sets how precise QHeaderView should calculate the size when ResizeToContents is used. A low value will provide a less accurate but fast auto resize while a higher value will provide a more accurate resize that however can be slow.

The number precision specifies how many sections that should be consider when calculating the preferred size. The default value is 1000 meaning that a horizontal column with auto-resize will look at maximum 1000 rows on calculating when doing an auto resize. Special value 0 means that it will look at only the visible area. Special value -1 will imply looking at all elements.

This value is used in QTableView::sizeHintForColumn(), QTableView::sizeHintForRow() and QTreeView::sizeHintForColumn(). Reimplementing these functions can make this function not having an effect.

See also: resizeContentsPrecision(), setSectionResizeMode(), resizeSections(), QTableView::sizeHintForColumn(), QTableView::sizeHintForRow(), QTreeView::sizeHintForColumn()

void QHeaderView::setSectionHidden	(	int	logicalIndex,

void QHeaderView::setSectionResizeMode	(	int	logicalIndex,
		ResizeMode	mode
	)

Sets the constraints on how the section specified by logicalIndex in the header can be resized to those described by the given mode. The logical index should exist at the time this function is called.

Note: This setting will be ignored for the last section if the stretchLastSection property is set to true. This is the default for the horizontal headers provided by QTreeView.

QHeaderView::defaultSectionSize

This property holds the default size of the header sections before resizing. This property only affects sections that have Interactive or Fixed as their resize mode.

By default, the value of this property is style dependent. Thus, when the style changes, this property updates from it. Calling setDefaultSectionSize() stops the updates, calling resetDefaultSectionSize() will restore default behavior.

QHeaderView::maximumSectionSize

This property holds the maximum size of the header sections. The maximum section size is the largest section size allowed. The default value for this property is 1048575, which is also the largest possible size for a section. Setting maximum to -1 will reset the value to the largest possible section size.

With the exception of stretch this property is honored by all resize modes.

QHeaderView::minimumSectionSize

This property holds the minimum size of the header sections. The minimum section size is the smallest section size allowed. If the minimum section size is set to -1, QHeaderView will use the maximum of the global strut or the font metrics size.

This property is honored by all resize modes.

The default value is false.

Note: The horizontal headers provided by QTreeView are configured with this property set to true, ensuring that the view does not waste any of the space assigned to it for its header. If this value is set to true, this property will override the resize mode set on the last section in the header.
