AtkComponent is implemented by AtkNoOpObject.

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.

AtkComponent: The AtkComponent structure does not contain any fields.

bounds-changed(atkcomponent, arg1, user.data)

The 'bounds-changed" signal is emitted when the bposition or size of the a component changes.

atkcomponent: [AtkComponent] the object which received the signal.
arg1: [AtkRectangle] The AtkRectangle giving the new position and size.
user.data: [R object] user data set when the signal handler was connected.
