JDK-4083501 - Need Input Polling for Games (keyboard, etc)
Description
A DESCRIPTION OF THE REQUEST :
It would be nice to have a function to get the state of a key. E.g. I need to detect in my mousewheel listener if the Ctrl key is down or not.
So I propose to add a function like this: boolean getKeyState(int key)
so I can use getKeyState(KeyEvent.VK_Control) to see if the key is down at the moment the function is called.

EVALUATION We already have similar one: 4083501 and it describes the problem in a whole for input devices.

EVALUATION You can detect if the CTRL key is down by asking the MouseWheelEvent with getModifiers() or getModifiersEx(). However, the request for querying key state sounds interesting. Re-assigning to AWT to evaluate this.
