Java Keyword Demo

Hello,

I would like to be able to refresh the "hightlight" when opening the file, but with this code, the "highlight" is only done after editing the file.

codeArea.richChanges()
                .filter(ch -> !ch.getInserted().equals(ch.getRemoved()))
                .successionEnds(Duration.ofMillis(100))
                .supplyTask(this::computeHighlightingAsync)
                .awaitLatest(codeArea.richChanges())
                .filterMap(t -> {
                    if(t.isSuccess()) {
                        return Optional.of(t.get());
                    } else {
                        t.getFailure().printStackTrace();
                        return Optional.empty();
                    }
                })
                .subscribe(this::applyHighlighting);

This is the code found in the java keyword demo in Async

How can I do this?

Thank you !

What have you tried so far?

[WinXaito]

And well not much, what I would like to call codeArea.richChanges() without making a change in codeArea, but I do not know how to do it, you understand?

[WinXaito]

Okay, I'm so sorry, I've resolved my problem.. But I don't know why. I have inversed my variable declaration and the problem has been solved.

So I have an another questions, codeArea.positionCaret(0); is indicated @deprecated, how can I use ? Thanks !

[JordanMartinez]

No worries. You should be using codeArea.moveTo(absolutePosition) instead or its variant moveTo(paragraphIndex, linePosition)

Okay. Thanks !!
