Execute some code after ENTER Key pressed

[firm1]

Hi,

What is the best way with RichtexFx to execute some code after ENTER Key ? I use 0.6.10 release.

I want if possible override this line for example, but i don't know how i can do that.

Can you explain me please ?

Hi,

if you are using 0.6.10, you actually need to look at this version of the file, which uses an older version of WellBehavedFX.

You will need to do something like this:

// define the event handler
EventHandler<KeyEvent> handler = EventHandlerHelper
        .on(keyPressed(ENTER)).act(e -> { /* code to execute on Enter goes here */ })
        .create();

// install the event handler
EventHandlerHelper.install(area.onKeyPressedProperty(), handler);

Thank for answer.

But this code override the Enter key behavior. I just need to add something
after existing behavior, not rewrite.

The most reliable way is to first replicate in your handler whatever StyledTextAreaBehavior does, i.e. area.replaceSelection("\n"):

EventHandler<KeyEvent> handler = EventHandlerHelper
        .on(keyPressed(ENTER)).act(e -> {
                area.replaceSelection("\n");
                /* your code goes here */
        })
        .create();

You could also just try using the usual area.addEventHandler(KeyEvent.KEY_PRESSED, e -> { ... }), but there is no guarantee that this will be called after the default handler.

Ok thanks for your advice.

It's ok for me
