Detailed Description

The QTreeView class provides a default model/view implementation of a tree view.

A QTreeView implements a tree representation of items from a model. This class is used to provide standard hierarchical lists that were previously provided by the QListView class, but using the more flexible approach provided by Qt's model/view architecture.

The QTreeView class is one of the Model/View Classes and is part of Qt's model/view framework.

QTreeView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class.

It is simple to construct a tree view displaying data from a model. In the following example, the contents of a directory are supplied by a QFileSystemModel and displayed as a tree:

QFileSystemModel *model = new QFileSystemModel;

model->setRootPath(QDir::currentPath());

QTreeView *tree = new QTreeView(splitter);

tree->setModel(model);

The model/view architecture ensures that the contents of the tree view are updated as the model changes.

Items that have children can be in an expanded (children are visible) or collapsed (children are hidden) state. When this state changes a collapsed() or expanded() signal is emitted with the model index of the relevant item.

The amount of indentation used to indicate levels of hierarchy is controlled by the indentation property.

Headers in tree views are constructed using the QHeaderView class and can be hidden using header()->hide(). Note that each header is configured with its stretchLastSection 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.

Key Bindings

QTreeView supports a set of key bindings that enable the user to navigate in the view and interact with the contents of items:

KeyAction

Up Moves the cursor to the item in the same column on the previous row. If the parent of the current item has no more rows to navigate to, the cursor moves to the relevant item in the last row of the sibling that precedes the parent.

Down Moves the cursor to the item in the same column on the next row. If the parent of the current item has no more rows to navigate to, the cursor moves to the relevant item in the first row of the sibling that follows the parent.

Left Hides the children of the current item (if present) by collapsing a branch.

Minus Same as LeftArrow.

Right Reveals the children of the current item (if present) by expanding a branch.

Plus Same as RightArrow.

Asterisk Expands all children of the current item (if present).

PageUp Moves the cursor up one page.

PageDown Moves the cursor down one page.

Home Moves the cursor to an item in the same column of the first row of the first top-level item in the model.

End Moves the cursor to an item in the same column of the last row of the last top-level item in the model.

F2 In editable models, this opens the current item for editing. The Escape key can be used to cancel the editing process and revert any changes to the data displayed.

A Windows XP style tree view. A Macintosh style tree view. A Plastique style tree view.

Improving Performance

It is possible to give the view hints about the data it is handling in order to improve its performance when displaying large numbers of items. One approach that can be taken for views that are intended to display items with equal heights is to set the uniformRowHeights property to true.

Returns the rectangle on the viewport occupied by the item at index. If the index is not visible or explicitly hidden, the returned rectangle is invalid.

Implements QtGui.QAbstractItemView.

override QRegion QtGui.QTreeView.VisualRegionForSelection ( QItemSelection  selection )

protectedvirtual

Reimplemented from QAbstractItemView::visualRegionForSelection().

Returns the rectangle from the viewport of the items in the given selection.

Since 4.7, the returned region only contains rectangles intersecting (or included in) the viewport.

Implements QtGui.QAbstractItemView.

Property Documentation

new bool QtGui.QTreeView.AllColumnsShowFocus

getset

This property holds whether items should show keyboard focus using all columns.

If this property is true all columns will show focus, otherwise only one column will show focus.

The default is false.

This property was introduced in Qt 4.2.

new bool QtGui.QTreeView.Animated

getset

This property holds whether animations are enabled.

If this property is true the treeview will animate expandsion and collasping of branches. If this property is false, the treeview will expand or collapse branches immediately without showing the animation.

By default, this property is false.

This property was introduced in Qt 4.2.

new int QtGui.QTreeView.AutoExpandDelay

getset

This property holds the delay time before items in a tree are opened during a drag and drop operation.

This property holds the amount of time in milliseconds that the user must wait over a node before that node will automatically open or close. If the time is set to less then 0 then it will not be activated.

By default, this property has a value of -1, meaning that auto-expansion is disabled.

This property was introduced in Qt 4.3.

Slot<QModelIndex> QtGui.QTreeView.Collapsed

addremove

This signal is emitted when the item specified by index is collapsed.

new IQTreeViewSignals QtGui.QTreeView.Emit

getprotected

Slot<QModelIndex> QtGui.QTreeView.Expanded

addremove

This signal is emitted when the item specified by index is expanded.

See also setExpanded().

new bool QtGui.QTreeView.ExpandsOnDoubleClick

getset

This property holds whether the items can be expanded by double-clicking.

This property holds whether the user can expand and collapse items by double-clicking. The default value is true.

This property was introduced in Qt 4.4.

new QHeaderView QtGui.QTreeView.Header

getset

Returns the header for the tree view.

Sets the header for the tree view, to the given header.

The view takes ownership over the given header and deletes it when a new header is set.

new bool QtGui.QTreeView.HeaderHidden

getset

This property holds whether the header is shown or not.

If this property is true, the header is not shown otherwise it is. The default value is false.

This property was introduced in Qt 4.4.

new int QtGui.QTreeView.Indentation

getset

This property holds indentation of the items in the tree view.

This property holds the indentation measured in pixels of the items for each level in the tree view. For top-level items, the indentation specifies the horizontal distance from the viewport edge to the items in the first column; for child items, it specifies their indentation from their parent items.

By default, this property has a value of 20.

new bool QtGui.QTreeView.ItemsExpandable

getset

This property holds whether the items are expandable by the user.

This property holds whether the user can expand and collapse items interactively.

By default, this property is true.

override QAbstractItemModel QtGui.QTreeView.Model

getset

Reimplemented from QAbstractItemView::setModel().

override QModelIndex QtGui.QTreeView.RootIndex

getset

Reimplemented from QAbstractItemView::setRootIndex().

new bool QtGui.QTreeView.RootIsDecorated

getset

This property holds whether to show controls for expanding and collapsing top-level items.

Items with children are typically shown with controls to expand and collapse them, allowing their children to be shown or hidden. If this property is false, these controls are not shown for top-level items. This can be used to make a single level tree structure appear like a simple list of items.

By default, this property is true.

override QItemSelectionModel QtGui.QTreeView.SelectionModel

getset

Reimplemented from QAbstractItemView::setSelectionModel().

new bool QtGui.QTreeView.SortingEnabled

getset

This property holds whether sorting is enabled.

If this property is true, sorting is enabled for the tree; if the property is false, sorting is not enabled. The default value is false.

Note: In order to avoid performance issues, it is recommended that sorting is enabled after inserting the items into the tree. Alternatively, you could also insert the items into a list before inserting the items into the tree.

This property was introduced in Qt 4.2.

new QMetaObject QtGui.QTreeView.StaticMetaObject

staticget

new bool QtGui.QTreeView.UniformRowHeights

getset

This property holds whether all items in the treeview have the same height.

This property should only be set to true if it is guaranteed that all items in the view has the same height. This enables the view to do some optimizations.

The height is obtained from the first item in the view. It is updated when the data changes on that item.

By default, this property is false.

new bool QtGui.QTreeView.WordWrap

getset

This property holds the item text word-wrapping policy.

If this property is true then the item text is wrapped where necessary at word-breaks; otherwise it is not wrapped at all. This property is false by default.

Note that even if wrapping is enabled, the cell will not be expanded to fit all text. Ellipsis will be inserted according to the current textElideMode.

This property was introduced in Qt 4.3.
