acceleratorValid
fun acceleratorValid(keyval: <Error class: unknown class>, modifiers: <Error class: unknown class>): Boolean
Determines whether a given keyval and modifier mask constitute a valid keyboard accelerator.
For example, the %GDK_KEY_a keyval plus %GDK_CONTROL_MASK mark is valid, and matches the “Ctrl+a” accelerator. But, you can't, for instance, use the %GDK_KEY_Control_L keyval as an accelerator.
Return
true if the accelerator is valid
Parameters
keyval
a GDK keyval
modifiers
modifier mask
