WkImageButtonView

WkImageButtonViews provide a mechanism to initiate an action when clicked on. They call their clicked event when they are pressed and released. Image buttons may have an image and/or text string for a label. The image and text labels may be layed out either vertically or horizontally. Different images and labels can be specified for the up state, the pressed state and the disabled state.
