Method Details

getParent(self)

source code

Widgets are kept in a hierarchy, and widgets that have been added to a panel will have a parent widget that contains them. This retrieves the containing widget for this widget.

setParent(self, parent)

source code

Update the parent attribute. If the parent is currently attached to the DOM this assumes we are being attached also and calls onAttach().

removeFromParent(self)

source code

Remove ourself from our parent. The parent widget will call setParent(None) on us automatically
