Hello Mirek,
I have further investigated the key handling on X!!, and found that numpad virtual keycodes are not propagated properly:
Here is the current situation:
- When Numlock is ON, the characters corresponing to the numpad keys (0-9, +-/*,) are dispatched. This is fine, nothing wrong here.
- However, when the same keys are pressed with CTRL or ALT modifier, they SHOULD send numpad keycodes, e.g, K_NUMPAD0-K_NUMPAD_9, and operators (K_ADD, K_SUBTRACT, etc.). This is the default behaviour of Upp on Windows and GTK (I don't have a Mac)
- But this is not happening on X11. Character codes are dispatched regardless of modifiers
So, I made a patch to remedy this problem. The patch, I believe, is at least a fix for some regression, if not an overall improvement in X11 key handling code.
Pleease review.
Best regards,
Oblivion
