TiledImageButtonStyle

touchgfx/containers/buttons/TiledImageButtonStyle.hpp

A tiled image button style. An tiled 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 tiled images depending on the state of the button (pressed or released).

The TiledImageButtonStyle does not 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.

Template Parameters:

T Generic type parameter. Typically a AbstractButtonContainer subclass.

See: AbstractButtonContainer
