Detailed Description

Small concept class.

Parts of the engine inherit this class so we can have generic clickable items. This is mainly for the button and the repeating button classes.

The reason for having the click functions here is that not all subclasses need to implement the click event in the same way; e.g. the repeating button clicks on the mouse down event and the normal button on the mouse click event.

Common signal handlers:

connect_signal_mouse_left_click
disconnect_signal_mouse_left_click
