A small project showing a single basic JavaFX control used to display contents from a JOGL GLAutoDrawable without relying on NEWT.
"But why create this when you have NewtCanvasJFX?"
Great question.
The short answer is that if you look at the NEWT canvas, the only way to pass a GLAutoDrawable is by wrapping it in a GLWindow to satisfy the Window constructor and that may not be ideal.
To elaborate, this means your canvas is actually empty and taking a Node.snapshot(SnapshotParameters, WritableImage) will show nothing. The canvas actually is controlling the position and size of a separate window floating on top of it. For simple applications this may be fine, but this conflicts with a number of use-cases.
- You can't use
StackPaneto draw on top of the canvas - You can't support mouse events on the canvas because the floating window will eat those
- You can't apply effects to the canvas, because its technically not the thing rendering the drawable
This implementation of GLCanvas for JavaFX mitigates all of those problems.
