Then maybe you can try to listen to that instead of the textProperty to see if that makes any difference. I don't really expect it to though, but worth a shot.

If that doesn't work, maybe create a minimal sample without binding, to see if that works at all.

I don't have time for any coding today, working on something else exciting for TornadoFX and Kotlin 🙂

it looks like the change handler is firing, but

scrollTop

is always 0 =\

@alexp11223 maybe you can instead publish a text received message to that you can call appendText on the textarea?

binding might not be right for this

i'd try subscribing to a model event, say a new log file line, in the view. call appendText when the new single line comes in. if that works, we can look on getting he V, VM and M layers right

@alexp11223 When textUpdated is called, scrollTop is automatically set to 0 again.

@edvin i don't think fighting between scrollTop and end will work

an outside the box solution would be a listview unless the amount of data was huge

@alexp11223 This would therefore happen whenever you call setText, or when the textProperty is bound. A workaround for this seems to be to use a listener on your viewModel property and calling

replaceText()

on the TextArea instead.

I got this from the

doSet

function of `TextArea`:

/** * doSet is called whenever the setText() method was called directly * on the TextInputControl, or when the text property was bound, * unbound, or reacted to a binding invalidation. It is not called * when modifications to the content happened indirectly, such as * through the replaceText / replaceSelection methods. * * @param value The new value */

i think appendText fits in that category too

doSet

goes on to call

textUpdated

which sets scrollTop to 0.

appendText calls replaceText

Good, then that would be the least wasteful solution, atleast if the text amount is huge.

what do you think about abandoning view / viewmodel binding in favor of a listener in the view. the listener will call appendText and decide exactly what to append as a diff of the viewmodel and getText?

hm. it worked once, after I removed another control at the bottom, but now it stopped working again =\

@User uploaded a file: Untitled

According to the docs, it shouldn't work, but you might be able to call

end

or set

scrollTop

after the change event is handled internally if you wrap your code inside the onChange listener in

runLater

.

I have a Button and when I set the graphic of it to ProgressIndicator, it causes the button to change size. Setting max dimensions for Button or ProgressIndicator don't seem to have any effects. Does anybody know what causes this and how it could be suppressed?

Well you could add the

ProgressIndicator

at the beginning and just toggle the visibility?

@nimakro How do I do that? At the moment all I am doing is calling

setGraphic

on the button and later on calling it again to set to null.

@sep This would be one way of doing it, not sure if it is the best way but it works.

Thanks @nimakro Yep, it is working. I'll just keep it like this until I have a better understanding of it.

No problem if you run into any other problems just let us know..

hello everyone!

I'm trying to create a shortcut for exiting the application. So far I am calling System.exit(0), but I feel there should be some way of closing the app by calling some app.close() or stage.close() function.
