BiResizeHandle

This component can be used to allow another component to be resizable using the mouse. The component can be used as a resize handle for the component to resize. It can also be used without adding it to another component by manually calling startResize in a mouse down event handler.

This class extends BiComponent and therefore all methods and fields available for BiComponent are also available for BiResizeHandle .
