Implementations

AtkComponent is implemented by AtkNoOpObject.

Detailed Description

AtkComponent should be implemented by most if not all UI elements with an actual on-screen presence, i.e. components which can be said to have a screen-coordinate bounding box. Virtually all widgets will need to have AtkComponent implementations provided for their corresponding AtkObject class. In short, only UI elements which are *not* GUI elements will omit this ATK interface.

A possible exception might be textual information with a transparent background, in which case text glyph bounding box information is provided by AtkText.

Structures
