e
Default function that is called when z-index is changed on the widget.
Parameters:
-
e
EventFacadeThe event facade of the change
_attachUIHandlesModal
()
Attaches UI Listeners for "clickoutside" and "focusoutside" on the widget. When these events occur, and the widget is modal, focus is shifted back onto the widget.
_bindUIModal
()
protected
Hooks up methods to be executed when the widget's visibility or z-index changes
This method in invoked after bindUI is invoked for the Widget class using YUI's aop infrastructure.
_blur
()
Blurs the widget.
_detachUIHandlesModal
()
Detaches all UI Listeners that were set in _attachUIHandlesModal from the widget.
_focus
()
Provides mouse and tab focus to the widget's bounding box.

_getMaskNode
()
Node
Returns the Y.Node instance of the maskNode
Returns:
_renderUIModal

protected
Adds modal class to the bounding box of the widget
This method in invoked after renderUI is invoked for the Widget class using YUI's aop infrastructure.
_repositionMask
-
