Dear all!
I'm still working on this kind of button-like widget and I want to implement
the behaviour when hovering over the button.
Unfortunately, the button_state does not work as I expected (maybe I
expected it wrong).
When I click somewhere, continue to hold down the mouse button (so there is
no SDL_MOUSEBUTTONUP event) and move the mouse, shouldn't
$event->button_state return SDL_PRESSED (which is 1)?
Because, using the script attached, I always get SDL_RELEASED (0).
The single case where I get SDL_PRESSED is when I check it on
SDL_MOUSEBUTTONDOWN.
So, is this behaviour intended?
Or, to ask it in another way: do I have to keep track of the
SDL_MOUSEBUTTONUP event myself in order to determine if the user still holds
down the mouse button?
Kind regards,
Alex
