Hello,

Is there anyway to query if the Capslock key id on?

Thanks,
Dave

Check for KMOD_CAPS in the mod field of the SDL_keysym?

There is also a keycode for the actual key: SDLK_CAPSLOCK. I suppose tracking
the state of that should work, but I'm not sure if you get the state of the
*key* or the keyboard/system capslock state... I would assume and hope for the
former. :-)

Yeah I am worried that if the user has the Caps lock on and he hits it
that will flip my bool value of the status of the caps lock key.

I would rather just test to see if the key is in fact activated....

I looked at SDL_GetModState() and checked the return value. I am getting
4096 and 12288? Isn't Caps lock = 8912

Thanks

Nevermind I got it!

a bit of Bit math ;)

int temp = SDL_GetModState();
temp = temp & KMOD_CAPS;
if(temp == KMOD_CAPS)
std::cout << "CAP ON";
Thanks

You shouldn't just flip the bool, but rather check what the event says about
the new state.

However, there is still a risk of losing some events and getting ouf of sync
when you're in a windowed environment. I'm not sure if SDL_WM_GrabInput() can
*totally* prevent that on all platforms either...

That would be 2^13 = 8192, and 12280 = 8192 + 4096, that is, bits 12 and 13
set. :-)
