In addition to signals, there are low-level ~events~ corresponding to the X Window system event mechanism. They can be connected just like signals. These events are: event button_press_event button_release_event motion_notify_event delete_event destroy_event expose_event key_press_event key_release_event enter_notify_event leave_notify_event configure_event focus_in_event focus_out_event map_event unmap_event property_notify_event selection_clear_event selection_request_event selection_notify_event proximity_in_event proximity_out_event drag_begin_event drag_request_event drag_end_event drop_enter_event drop_leave_event drop_data_available_event other_event
