Package input_adapter consists of ActionManager and ComplexActionInterface which together allow to recognize more keyboard events than usual krita action does.
While usual actions can only recognize key press, implementing ComplexActionInterface lets you override methods performed on:
- key press
- short key release
- long key release
- every key release
Each action needs to have public name: str attribute which is the same, as the one used in .action file, as well as short_vs_long_press_time: float which determines how many seconds need to elapse to consider that a key press was long.
Use ActionManager instance to bind objects of those custom actions to krita during CreateActions phase:
"""
Print whether action key was released before of after
0.2 seconds from being pressed.
"""
