modifierMod2 constant Null safety

int const modifierMod2

This mask is used to check the RawKeyEventDataLinux.modifiers field to test whether the second modifier key is pressed (assumed to be mapped to num lock).

Use this value if you need to decode the RawKeyEventDataLinux.modifiers field yourself, but it's much easier to use isModifierPressed if you just want to know if a modifier is pressed. This is especially true on GTK, since its modifiers don't include the effects of the current key event.

Implementation

static const int modifierMod2 = 1 << 4;
