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.

UI4.Widgets.AttributeHistoryTreeWidget

class UI4.Widgets.AttributeHistoryTreeWidget

Bases: QT4Widgets.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',
                                             NodegraphAPI.GetNode('AttributeSet'))
attributeHistoryTreeWidget.resize(400, 100)
attributeHistoryTreeWidget.show()
attributeHistoryTreeWidget.getNodeHistory()

classmethod GetAttributeDataToDisplay(attribute)

Return type

str

Parameters

attribute (FnAttribute.DataAttribute) – The attribute whose data you wish to display.

Returns

A string representing the data in the given attribute. If more than MaxNumValuesToDisplay values are present, then only this number of values are returned, followed by ‘…’.

classmethod GetDisplayTextAndIconType(historyEntry)

Converts a history entry as returned by the AttributeHistory module into text to display, and a corresponding icon.

Return type

tuple of (str, int)

TimerDelay = 100

__init__(parent=None)

Initializes an instance of the class.
