Detailed Description¶

The PySide.QtGui.QTreeWidgetItem class provides an item for use with the PySide.QtGui.QTreeWidget convenience class.

Tree widget items are used to hold rows of information for tree widgets. Rows usually contain several columns of data, each of which can contain a text label and an icon.

The PySide.QtGui.QTreeWidgetItem class is a convenience class that replaces the QListViewItem class in Qt 3. It provides an item for use with the PySide.QtGui.QTreeWidget class.

Items are usually constructed with a parent that is either a PySide.QtGui.QTreeWidget (for top-level items) or a PySide.QtGui.QTreeWidgetItem (for items on lower levels of the tree). For example, the following code constructs a top-level item to represent cities of the world, and adds a entry for Oslo as a child item:
cities =  QTreeWidgetItem(treeWidget)
cities.setText(0, tr("Cities"))
osloItem =  QTreeWidgetItem(cities)
osloItem.setText(0, tr("Oslo"))
osloItem.setText(1, tr("Yes"))
Items can be added in a particular order by specifying the item they follow when they are constructed:
planets =  QTreeWidgetItem(treeWidget, cities)

planets.setText(0, tr("Planets"))
Each column in an item can have its own background brush which is set with the PySide.QtGui.QTreeWidgetItem.setBackground() function. The current background brush can be found with PySide.QtGui.QTreeWidgetItem.background() . The text label for each column can be rendered with its own font and brush. These are specified with the PySide.QtGui.QTreeWidgetItem.setFont() and PySide.QtGui.QTreeWidgetItem.setForeground() functions, and read with PySide.QtGui.QTreeWidgetItem.font() and PySide.QtGui.QTreeWidgetItem.foreground() .

The main difference between top-level items and those in lower levels of the tree is that a top-level item has no PySide.QtGui.QTreeWidgetItem.parent() . This information can be used to tell the difference between items, and is useful to know when inserting and removing items from the tree. Children of an item can be removed with PySide.QtGui.QTreeWidgetItem.takeChild() and inserted at a given index in the list of children with the PySide.QtGui.QTreeWidgetItem.insertChild() function.

By default, items are enabled, selectable, checkable, and can be the source of a drag and drop operation. Each item’s flags can be changed by calling PySide.QtGui.QTreeWidgetItem.setFlags() with the appropriate value (see Qt.ItemFlags ). Checkable items can be checked and unchecked with the PySide.QtGui.QTreeWidgetItem.setCheckState() function. The corresponding PySide.QtGui.QTreeWidgetItem.checkState() function indicates whether the item is currently checked.

Subclassing¶

When subclassing PySide.QtGui.QTreeWidgetItem to provide custom items, it is possible to define new types for them so that they can be distinguished from standard items. The constructors for subclasses that require this feature need to call the base class constructor with a new type value equal to or greater than UserType .
