Method Detail

post

public void post(Key key,
        boolean pressed,
        char typedCh)

Posts a key event received from elsewhere (i.e. a native UI component). This is useful for applications that are using GL in Canvas mode and sharing keyboard focus with other (non-GL) components. The event will be queued and dispatched on the next frame, after GL keyboard events.

Note: the resulting event will be sent with time = 0, since the GL event time is inaccessible and platform dependent.

Parameters:

key - the key that was pressed or released, or null for a char typed event

pressed - whether the key was pressed or released, ignored if key is null

typedCh - the character that was typed, ignored if key is not null
