Sortable Tree Widgets

Sortable tree widgets are tree widgets that provide additional functionality on top of what the underlying QtWidgets.QTreeWidget class provides, notably for dragging, dropping, and sorting of tree widget items.

The classes listed here are all derived from QT4Widgets.SortableTreeWidget.


class UI4.Widgets.AttributeHistoryTreeWidget

Bases: QT4Widgets-v0.SortableTreeWidget.SortableTreeWidget

Class implementing a tree widget that wraps AttributeHistory commands, and displays attribute history results.

Code example:

attributeHistoryTreeWidget = UI4.Widgets.AttributeHistoryTreeWidget()
attributeHistoryTreeWidget.initializeHistory('/root/world/cam/camera', 'geometry.fov',
attributeHistoryTreeWidget.resize(400, 100)
