getSubPartElement

public com.google.gwt.user.client.Element getSubPartElement(String subPart)
Description copied from interface: SubPartAware
Locates an element inside a component using the identifier provided in subPart. The subPart identifier is component specific and may be any string of characters, numbers, space characters and brackets.

Specified by:
getSubPartElement in interface SubPartAware
Parameters:
subPart - The identifier for the element inside the component
Returns:
The element identified by subPart or null if the element could not be found.

getSubPartName

public String getSubPartName(com.google.gwt.user.client.Element subElement)
Description copied from interface: SubPartAware
Provides an identifier that identifies the element within the component. The subElement is a part of the component and must never be null.

Note! getSubPartElement(getSubPartName(element)) == element is not always true. A component can choose to provide a more generic identifier for any given element if the results of all interactions with subElement are the same as interactions with the element identified by the return value. For example a button can return an identifier for the root element even though a DIV inside the button was passed as subElement because interactions with the DIV and the root button element produce the same result.

Specified by:
getSubPartName in interface SubPartAware
Parameters:
subElement - The element the identifier string should uniquely identify
Returns:
An identifier that uniquely identifies subElement or null if no identifier could be provided.

ensureHidden

public void ensureHidden(ActionOwner actionOwner)
Hides context menu if it is currently shown by given action owner.
