Synopsis

loadUI([listTypes=boolean], [uiFile=string], [uiString=string], [verbose=boolean], [workingDirectory=string])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

loadUI is undoable, NOT queryable, and NOT editable.

loadUI command allows loading of a user interface created in Trolltech Qt Designer.
Some Qt classes have equivalents in Maya. If a widget's class is recognized, the Maya-equivelent will be created instead.
Any dynamic properties on a widget which start with a '-' character will be treated as a MEL flag/value pair. Similarly, any which start with a '+' will be treated as a Python flag/value pair. Such pairs will be applied to the widget upon creation.

Return value
