Why can my window not reveive button_press signal?
I want to make a window, which will response when my mouse presses on it.
However I failed to do so when I rewrite the on_button_press_event function.
Who can explain it to me?
Thank you in advance.
My problem has been solved by adding the button_press_event, however, a
new problem arised too.
When I add the button_release_event and rewrite the
on_button_release_event() function, there is no response at all.
