said to have a screen-coordinate bounding box. Virtually all
widgets will need to have <a class="link" href="AtkComponent.html" title="AtkComponent"><span class="type">AtkComponent</span></a> implementations provided
for their corresponding <a class="link" href="AtkObject.html" title="AtkObject"><span class="type">AtkObject</span></a> 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
