Description Sven Gothel 2019-03-28 18:01:57 CET
Add JavaFX Support for NEWT utilizing native Window parenting via NewtCanvasJFX.

- NewtCanvasJFX shall be a JavaFX Canvas Node
- It shall allow attaching a native NEWT Window to the JavaFX Node's native Window (if attached).
    
The mechanism shall be similar to NewtCanvasAWT and NewtCanvasSWT.
    
Implementation shall support placing the NEWT Window
within the JavaFX scene of the native window correctly,
as well as support the following different lifecycles
- attach NewtCanvasJFX to already visible group->scene->window
- attach NewtCanvasJFX to not yet visible or attached group->scene->window
- attach NEWT Window before or after NewtCanvasJFX's visibility

The attached NEWT child window will be opaque on-top of the 
native root JavaFX window (or stage) - similar to NewtCanvasAWT when used within a Swing layout.
Comment 1 Sven Gothel 2019-03-28 18:03:00 CET
Support shall start with OpenJDK-8 and OpenJFX-8,
then later shall support OpenJDK-11 and OpenJFX-11 according to Bug 1363.
Comment 2 Sven Gothel 2019-03-28 18:10:08 CET
NewtCanvasJFX implementation has reached a well working stage already.

It is covered by unit test: TestNewtCanvasJFXGLn
    
This is the initial commit for JavaFX support and has been tested on
- OpenJDK 8 + OpenJFX 8
- GNU/Linux X11
- Windows

Note regarding JFXEDTUtil commit 8a66defd3c2c96b05c8868d5edb604e3564ff66d:

Utilize JFXEDTUtil per default, supporting the Windows Platform.
    
On [GNU/Linux] X11 JFXEDTUtil is not required, since X11 can handle multi-threaded native parenting,
however, the Windows platform does require JFXEDTUtil.
    
Currently the default is to use JFXEDTUtil, which operates solely on the JavaFX thread
for windowing lifecycle and even-dispatch operations.
    
This behavior can be toggled via the boolean property 'jogamp.newt.javafx.UseJFXEDT',
which currently defaults to 'true'
    
This behavior might be analyzed in more detail for a fine grained EDTUtil decision.
