cleanupWrappers

public void cleanupWrappers()

Cleanup old wrappers which have been left empty by other inner layouts moving the widget from the wrapper into their own hierarchy. This usually happens when a call to setWidget(widget) is done in an inner layout which automatically detaches the widget from the parent, in this case the wrapper, and re-attaches it somewhere else. This has to be done in the layout phase since the order of the hierarchy events are not defined.

setWidgetWrapperStyleNames

public void setWidgetWrapperStyleNames(com.google.gwt.user.client.ui.Widget widget,
                                       String... stylenames)

Sets style names for the wrapper wrapping the widget in the layout. The style names will be prefixed with v-absolutelayout-wrapper.

Parameters:

widget - The widget which wrapper we want to add the stylenames to

stylenames - The style names that should be added to the wrapper
