<p><a class="link" href="AtkComponent.html" title="AtkComponent"><span class="type">AtkComponent</span></a> 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

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.</p>
<p>A possible exception might be textual information with a
transparent background, in which case text glyph bounding box
information is provided by <a class="link" href="AtkText.html" title="AtkText"><span class="type">AtkText</span></a>.</p>
