Returns true if the specified key has been pressed, otherwise false is returned.
This method uses a global state to track whether any KEYDOWN events have occurred since the last call. If two different parts of your program both call this method, only one of them will detect that the key was pressed. The event system should be used for finer control over keyboard input.
Any of the following key codes can be used in this command.
This example uses the space key to control the color of a panel widget.
