Threading: SWT events/ FX events [message #1760467]

HI,

I am wondering on which thread are UI events processed?

In our Eclipse RCP application, events coming from SWT widgets are handled on the main thread. Nevertheless, if I open an FX view just before, those events are handled on the JavaFX Application Thread.

Are these threads maybe the same?

JavaFX and SWT run on the same native event Thread unlike swing/awt who has it's own

Hi Thomas,
thanks for replying. Does that mean

Display.getDefault().asyncExec();

is effectively the same as

Platform.runLater();

?
Is the 'main' thread renamed after the FX Platform was started? Since the thread name is 'main' and 'Java FX Application Thread' according to the logger.

No not the same but similar. Calling from fx to SWT does not require any thread sync!

What about the other way around?

Same no sync needed when calling fx from SWT nor if SWT calls into FX
