Andy,

Could you elaborate on why you want to see KeyEvents for dead keys on Linux? \
https://bugs.openjdk.org/browse/JDK-8172867

On Windows dead keys are delivered as KeyEvents. The dead keys generate KEY_PRESSED \
events and the final composed character is delivered in a KEY_TYPED event. This \
reflects how the OS handles dead keys.

On Mac dead keys are handled using InputMethodEvents. The dead keys generated \
composed events and the final character is presented as committed text. This also \
reflects how the OS handles dead keys.

X11 follows the Mac model but JavaFX does not implement this completely (it only \
sends the final commit event). I haven't delved into the code in detail but I suspect \
fleshing out the InputMethodEvent path to match the Mac would be much easier than \
trying to force Linux to deliver the same event stream as Windows.

Martin
