finite_key_down

The finite_key_down returns whether a given FiniteKey is being pushed down.

bool finite_key_down(FiniteKey key, FiniteKeyboard *board)

Parameters

Type	Description
`FiniteKey key`	The FiniteKey to check the state of
`FiniteKeyboard *board`	The FiniteKeyboard to check the state from

Code Example

#include <finite/draw.h>
#include <finite/input.h>

FiniteShell *myShell = finite_shell_init("wayland-0");

if (!myShell) {
    FINITE_LOG_FATAL("Unable to init shell");
}

FiniteKeyboard *kbd = finite_input_keyboard_init(myShell->display);

while (wl_display_dispatch(myShell->display) != -1) {
    if (!finite_key_valid(FINITE_KEY_A)) {
        FINITE_LOG_ERROR("Finite Key A is not valid");
    }

    if (finite_key_down(FINITE_KEY_A, kbd)) {
        FINITE_LOG("A is down");
    }
}

Standard Usage

Developers should ALWAYS call finite_key_valid to verify a FINITE_KEY’s existence in the internal finite_key_lookup table. Just because an enum exists does not mean that the evdev code for that input option is present.
