Examples of rocket.widget.client.Hijacker

rocket.widget.client.Hijacker
This class provides a simple mechanism to store the dom location of a given element, and have the same element restored to recorded location. This class is used to implement hijacking of dom elements to a supported wrapper widget etc. passing a TEXTAREA element to a TextArea widget. The TextArea typically adds the wrapped TextArea widget to the RootPanel. The RootPanel class then adds the TEXTAREA element to the document body. The hijacker then restores the TEXTAREA element to its original dom location, thus making everything just right. @author Miroslav Pokorny
