Detailed Description

The QTreeWidget class provides a tree view that uses a predefined tree model.

The QTreeWidget class is a convenience class that provides a standard tree widget with a classic item-based interface similar to that used by the QListView class in Qt 3. This class is based on Qt's Model/View architecture and uses a default model to hold items, each of which is a QTreeWidgetItem.

Developers who do not need the flexibility of the Model/View framework can use this class to create simple hierarchical lists very easily. A more flexible approach involves combining a QTreeView with a standard item model. This allows the storage of data to be separated from its representation.

In its simplest form, a tree widget can be constructed in the following way:

QTreeWidget treeWidget = new QTreeWidget();

treeWidget->setColumnCount(1);

QList<QTreeWidgetItem *> items;

for (int i = 0; i < 10; ++i)

items.append(new QTreeWidgetItem((QTreeWidget)0, QStringList(QString("item: %1").arg(i))));

treeWidget->insertTopLevelItems(0, items);

Before items can be added to the tree widget, the number of columns must be set with setColumnCount(). This allows each item to have one or more labels or other decorations. The number of columns in use can be found with the columnCount() function.

The tree can have a header that contains a section for each column in the widget. It is easiest to set up the labels for each section by supplying a list of strings with setHeaderLabels(), but a custom header can be constructed with a QTreeWidgetItem and inserted into the tree with the setHeaderItem() function.

The items in the tree can be sorted by column according to a predefined sort order. If sorting is enabled, the user can sort the items by clicking on a column header. Sorting can be enabled or disabled by calling setSortingEnabled(). The isSortingEnabled() function indicates whether sorting is enabled.

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

Constructor & Destructor Documentation

QtGui.QTreeWidget.QTreeWidget ( System.Type  dummy )

protected

QtGui.QTreeWidget.QTreeWidget

(

QWidget

parent = null

)

Constructs a tree widget with the given parent.

Member Function Documentation

new void QtGui.QTreeWidget.AddTopLevelItem

(

QTreeWidgetItem

item

)

Appends the item as a top-level item in the widget.

This function was introduced in Qt 4.1.

See also insertTopLevelItem().

new void QtGui.QTreeWidget.AddTopLevelItems

(

System.Collections.Generic.List< QTreeWidgetItem >

items

)

Appends the list of items as a top-level items in the widget.

See also insertTopLevelItems().

new void QtGui.QTreeWidget.Clear

(

)

Clears the tree widget by removing all of its items and selections.

Note: Since each item is removed from the tree widget before being deleted, the return value of QTreeWidgetItem::treeWidget() will be invalid when called from an item's destructor.

See also takeTopLevelItem(), topLevelItemCount(), and columnCount().

new void QtGui.QTreeWidget.ClosePersistentEditor	(	QTreeWidgetItem	item,
		int	column = 0
	)

Closes the persistent editor for the item in the given column.

This function has no effect if no persistent editor is open for this combination of item and column.

See also openPersistentEditor().

new void QtGui.QTreeWidget.CollapseItem

(

QTreeWidgetItem

item

)

Closes the item. This causes the tree containing the item's children to be collapsed.

See also expandItem(), currentItem(), itemAt(), and topLevelItem().

override void QtGui.QTreeWidget.CreateProxy ( )

virtual

Reimplemented from QtGui.QTreeView.

new int QtGui.QTreeWidget.CurrentColumn

(

)

Returns the current column in the tree widget.

This function was introduced in Qt 4.1.

See also setCurrentItem() and columnCount().

new void QtGui.QTreeWidget.Dispose

(

)

virtual bool QtGui.QTreeWidget.DropMimeData ( QTreeWidgetItem  parent, int  index, QMimeData  data, Qt.DropAction  action  )

protectedvirtual

Handles the data supplied by a drag and drop operation that ended with the given action in the index in the given parent item.

The default implementation returns true if the drop was successfully handled by decoding the mime data and inserting it into the model; otherwise it returns false.

See also supportedDropActions().

new void QtGui.QTreeWidget.EditItem	(	QTreeWidgetItem	item,
		int	column = 0
	)

Starts editing the item in the given column if it is editable.

new void QtGui.QTreeWidget.ExpandItem

item

)

Expands the item. This causes the tree containing the item's children to be expanded.

See also collapseItem(), currentItem(), itemAt(), topLevelItem(), and itemExpanded().

new System.Collections.Generic.List<QTreeWidgetItem> QtGui.QTreeWidget.FindItems	(	string	text,
		Qt.MatchFlag	flags,
		int	column = 0
	)

Returns a list of items that match the given text, using the given flags, in the given column.

new QModelIndex QtGui.QTreeWidget.IndexFromItem ( QTreeWidgetItem  item, int  column = 0  )

protected

Returns the QModelIndex assocated with the given item in the given column.

See also itemFromIndex() and topLevelItem().

new int QtGui.QTreeWidget.IndexOfTopLevelItem

(

QTreeWidgetItem

item

)

Returns the index of the given top-level item, or -1 if the item cannot be found.

See also sortItems() and topLevelItemCount().

new void QtGui.QTreeWidget.InsertTopLevelItem	(	int	index,
		QTreeWidgetItem	item

Inserts the list of items at index in the top level in the view.

Items that have already been inserted somewhere else wont be inserted.

This function was introduced in Qt 4.1.

See also addTopLevelItems().

new QTreeWidgetItem QtGui.QTreeWidget.InvisibleRootItem

(

)

Returns the tree widget's invisible root item.

The invisible root item provides access to the tree widget's top-level items through the QTreeWidgetItem API, making it possible to write functions that can treat top-level items and their children in a uniform way; for example, recursive functions.

This function was introduced in Qt 4.2.

new bool QtGui.QTreeWidget.IsFirstItemColumnSpanned

(

QTreeWidgetItem

item

)

Returns true if the given item is set to show only one section over all columns; otherwise returns false.

This function was introduced in Qt 4.3.

See also setFirstItemColumnSpanned().

new bool QtGui.QTreeWidget.IsItemExpanded

(

QTreeWidgetItem

item

)

Returns true if the given item is open; otherwise returns false.

This function is deprecated. Use QTreeWidgetItem::isExpanded() instead.

See also itemExpanded().

new bool QtGui.QTreeWidget.IsItemHidden

(

QTreeWidgetItem

item

)

Returns true if the item is explicitly hidden, otherwise returns false.

This function is deprecated. Use QTreeWidgetItem::isHidden() instead.

new bool QtGui.QTreeWidget.IsItemSelected

(

QTreeWidgetItem

item

)

Returns true if the item is selected; otherwise returns false.

This function is deprecated. Use QTreeWidgetItem::isSelected() instead.

See also itemSelectionChanged().

new bool QtGui.QTreeWidget.IsSortingEnabled

(

)

new QTreeWidgetItem QtGui.QTreeWidget.ItemAbove

(

QTreeWidgetItem

item

)

Returns the item above the given item.

This function was introduced in Qt 4.3.

new QTreeWidgetItem QtGui.QTreeWidget.ItemAt

See also visualItemRect().

new QTreeWidgetItem QtGui.QTreeWidget.ItemAt	(	int	x,
		int	y
	)

This is an overloaded function.

Returns a pointer to the item at the coordinates (x, y). The coordinates are relative to the tree widget's viewport().
