enum app_widget_ids

Event command ID for the application widgets.

Note

The command IDs cannot be 0, since this value is reserved for no command event callback for certain widgets.

Enumerator
SLIDER_ID	Event command ID for the slider.
BUTTON_ID	Event command ID for the button.

static void sub_frame_draw_handler ( struct win_window *  win, struct win_clip_region const *  clip  )
