[E-devel] [Question][Windows] Shift/Alt/Ctrl key press operation
cnook
I have a question about shift/alt/ctrl key press operation.
On the X environment, shift/alt/ctrl key press
event(EVAS_CALLBACK_KEY_DOWN) does not occur repeatedly .
But on the Windows, shift/alt/ctrl key press event occurs repeatedly.
Now let's suppose you have an application which takes care of
shift/alt/ctrl key press event.
The application would work improperly if there is not enough handling for
those key events.
So how about your opinion on this.
Should I change ecore_win32_things to occur EVAS_CALLBACK_KEY_DOWN event
once (not repeatedly)
Or should I change the Application....?
Would you ENLIGHTEN me on this question?
Sincerely,
Shinwoo Kim.

for modifiers (and locks - like capslock, numlock etc.) - yes, ecore_win32
should be3 changed to weed out key repeats of these. :(

thinking of that, what about the Win key ?

I have one more question.
On the Ubuntu, when you hold down the Space key, then DOWN and UP
event occur repeatedly
even though only DOWN event occurs on the Windows.. So my question is
as before...
Should I modify the ecore_win32_event? or Should the application
handle the case.?
Please ENLIGHTEN me again.. Thanks!
Sincerely,
Shinwoo Kim.

what is this is_keystroke stuff an why should it fire a key up (on wince/32)
during a key press?

You can check by adding two callbacks to one object for key_down and
key_up. When you hold down the key which makes WM_CHAR/SYSCHAR message,
both callbacks will be called. And the is_keystroke is true, if
WM_CHAR/SYSCHAR message fires.
