ImageButtonStyle

An image button style. This class is supposed to be used with one of the ButtonTrigger classes to create a functional button. This class will show one of two images depending on the state of the button (pressed or released).

The ImageButtonStyle will set the size of the enclosing container (normally AbstractButtonContainer) to the size of the pressed Bitmap. This can be overridden by calling setWidth/setHeight after setting the bitmaps.

The position of the bitmap can be adjusted with setBitmapXY (default is upper left corner).

Template Parameters:

T Generic type parameter. Typically a AbstractButtonContainer subclass.

See: AbstractButtonContainer
