Signals

button_down ( )

Emitted when the button starts being held down.

button_up ( )

Emitted when the button stops being held down.

pressed ( )

Emitted when the button is toggled or pressed. This is on button_down if action_mode is ACTION_MODE_BUTTON_PRESS and on button_up otherwise.

If you need to know the button's pressed state (and toggle_mode is active), use toggled instead.

toggled ( bool toggled_on )

Emitted when the button was just toggled between pressed and normal states (only if toggle_mode is active). The new state is contained in the toggled_on argument.
