Description copied from interface: ComponentRenderer

Returns the part of the given component that corresponds to the given point.

Specified by:

getComponentPart in interface ComponentRenderer

Parameters:

c - a component.

r - where the component is drawn.

expanded - if the component is exanded or not, i.e., if its sub components will be drawn also or not.

x0 - the x coordinate of the point of interest.

y0 - the y coordinate of the point of interest.

Returns:

the part of the given component that corresponds to the given point, or null if the given point does not correspond to any part of the given component.
