Description copied from interface: VisuallyLayoutable

Returns the visual bounds for the specified component, or null if the visual bounds can not be determined.

Specified by:

getVisualBounds in interface VisuallyLayoutable

Parameters:

c - JComponent to calculate visual margin for

type - The type of the visual margin.

width - Width of the component

height - Height of the component
