Struct Component 

pub struct Component { /* private fields */ }

The ATK interface provided by UI components which occupy a physical area on the screen. which the user can activate/interact with.

Component 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 Component implementations provided for their corresponding Object 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 Text.

Signals

bounds-changed

The ’bounds-changed“ signal is emitted when the bposition or size of the component changes.
