ah stupid me, found it in the very same location xD

If there is anyone out there. I'm trying to add a TimeLine to my tree, so that it scrolls when I drag and go off tree, as per a JavaFX article. I've got all the code into a Tornadofx view, with the exception of this:

KeyFrame(Duration.millis(20.0), "Scoll", (ActionEvent) -> { dragScroll() }))

I just can't get this created

any ideas?

https://stackoverflow.com/questions/30497775/want-to-trigger-scroll-when-dragging-node-outside-the-visible-area-in-scrollpane is the article

scrollTimeLine.getKeyFrames().add(KeyFrame(Duration.millis(20.0), "Scroll", (ActionEvent) -> { dragScroll() }))

complains with:

Multiple markers at this line - Classifier 'ActionEvent' does not have a companion object, and thus must be initialized here - Expecting ')' - Unexpected tokens (use ';' to separate expressions on the same line) - Unexpected tokens (use ';' to separate expressions on the same line) - The lambda expression is unused. If you mean a block, you can use 'run { ... }'

Aha, figured it. Thanks to the Login sample

hey @carldea. we're pretty active and sling a lot of code around so paste anything you get stuck on

For some reason, we have a run on Carl's, so I'll take CarlW if you're (anyone) not using my handle

I highly recommend Carl Dea's book "JavaFX 9 By Example" . it's good to have even if you're skipping 9 and 10 and heading straight into 11 when TornadoFX catches up

CarlW, I keep missing you on here. Thanks for the shout out of the book. I look forward to learning about TornadoFX and Kotlin. Although I am limited on how much time I can spend, I'll be sure to monitor the channel on Slack for news. 😁 Anyone knows if there's a roadmap or timeframe when TornadoFX/Kotlin is able to run on JDK 11 or 12? Thanks!

@carldea @thomasnield Feel free to review JFX 11 support for TornadoFX - https://github.com/edvin/tornadofx/pull/797

Lol, more Carl's.. Just what we need in the world!

Hi all, I'm now really happy with this! There's a few things to go, but basically, this provides my app the ability to use a TreeView for the file system. The menu can be used to add/rename/delete (BEWARE DELETE is the full directory! I'm going to show a pop-up). It also autoscroll up and down if you go to the top or bottom (although I think there may be a bug in the getY somewhere, so I use paneY; which doesn't work when you have full height of screen unless you pop a small empty label below the pane to ensure it goes off it). It auto expands or collapses a folder underneath the drag (delayed). It only allows dropping to a Folder. The file system is changed underneath too! So be careful! I suggest you create a temporary file directory to test it in. Things to do include: Sort the drop to ROOT (this isn't possible due to the whole cell width being selected; I need to find a solution). No error is shown if move cant happen (try dropping a file with same name into one that already has it).

I'd love comments/suggestions for improvement

mmmm, still a few bugs in the movement. Will fix. SO close

Hi, what is the recommended way to have a dialog/modal return a value to the calling view? I'd like to wait for it with coroutines or with a callback (so I can wrap it in a coroutine)

@louiscad - is the dialog blocking when you open it?

Not sure what you mean by blocking exactly, but I finally found a suspending way to await for modal (or any stage) being hidden:

suspend fun Stage.awaitHidden() {
    lateinit var listener: InvalidationListener
    val property = onHiddenProperty()
    try {
        suspendCancellableCoroutine<Unit> { c ->
            listener = InvalidationListener {
                c.resume(Unit)
            }
            property.addListener(listener)
        }
    } finally {
        property.removeListener(listener)
    }
}

see https://github.com/edvin/tornadofx/issues/226

i'm not sure the best way to handle this either, but it is such a common case ... it does seem like the type of thing TornadoFX could provide some functionality for (i'm not smart enough to think of how). I feel like there have been a few just little things that i do over and over with GUIs that TornadoFX has given me a helper for and made life very easy. This seems right up there for me.

@louiscad I'm on the train rn so I probably didn't read well but it sounds like you can accomplish your goal with just TornadoFX scopes and itemmodelviews

From issue 226 posted above - seems pretty straight forward.

@gtnarg what are you trying to accomplish?

This post looks 2 years old so I need some context

trying to answer @louiscad question 🙂
