If you don't do autocommit, you wouldn't see the change in the property value in the item itself, only in the

model.mainControl

facade property.

Sweet! Let me know if it doesn't work as you expect.

Thank you!

On the github page, I think you need to update the customer model / JSON example because

int("id")

returns

Int?

, but for the assigment to the property you need

Int

, so (at least I had to write)

id = int("id") ?: 0

@matthjes Good catch, updated 🙂

Do you know a way how I can force a JavaFX Property to notify listeners when I call setValue()? In my case the returned value from my rest call does not always change, but I still would like the observers get notified so they can, e.g., add a point to a line graph.

Ok, I can use an

InvalidationListener

for this...

I'm fighting with this for hours now and cannot make it work. I have a ScrollPane with a bunch of Nodes (like Labels) inside, I set

isFitToWidth = true

so it only scrolls vertically and the width of the ScrollPane should be the same as the width of the content, but the ScrollPane always ends up a few pixels short of the content width, which causes my Labels to ellipsize for example. This sounds like a very simple thing but I can't make it work. How do I make a ScrollPane fit to the width of it's content (because I only want vertical scrolling)? Surely I'm missing something. 😞

The thing is, if I set my scrollbar to be just 1px wide with CSS, everything works ok, so it seems like the ScrollPane has the correct width (the width of the content) and then the scrollbar takes some of the width for itself which upsets the content.

@Marcin Wisniowski I don't think TornadoFX has any special glue to help you here, but if you could post a self contained sample showcasing the issue I'm sure we can come up with a working solution 🙂

@edvin Here you go, if you run it you will see that some lines of text are ellipsized, I can't get rid of that.

@Marcin Wisniowski You don't need to call

this += label()

- the builders automatically add themselves to their parent. Remove

this +=

🙂

The issue here is that the labels accept to be reduced beyond their preferred size by default, while you want them to insist on their preferred size, right?

Yeah, I want the window to always be as wide as it needs so that all labels are displayed in full.

Thanks for the

this +=

comment!

@Marcin Wisniowski Just set

usePrefSize = true

on the labels to have them insist on their preferred size 🙂

That that does under the covers is

setMinSize(Region.USE_PREF_SIZE, Region.USE_PREF_SIZE)

.

Oh, that works, but now I get a horizontal scrollbar which I don't want, why does that happen? Shouldn't

isFitToWidth = true

prevent that?

@Marcin Wisniowski There are other mechanics involved since your scrollpane is the root of a Scene.

I just tried the

usePrefSize = true

in my actual code (where the ScrollPane is not the root) and I get the exact same behavior: Nothing is cut off (great!), but I get a horizontal scrollbar (bad).

@Marcin Wisniowski I think your maxHeight is messing with you. Just remove it and have the container figure it out. If it can't be higher, but needs to, the labels might report a larger prefWidth.

Here is a slightly rewritten example with no visible scrollbars by default.

But I actually need the maxHeight (or something equivalent), because I may have a lot of content in the ScrollPane, and I don't want the window to take the entire screen.

@Marcin Wisniowski Well, at that height, your content doesn't fit, hence you get the scrollbars.

Yes, the vertical one, but I don't want the horizontal one. I don't limit the width of the window.

I want the window to be as wide as it needs, but not too high, hence the vertical scrollbar I want.

@Marcin Wisniowski commented on @edvin’s file https://kotlinlang.slack.com/files/U0F3291QE/F6U7Y3E83/-.kt: I just learned a few things 🙂

@Marcin Wisniowski Hehe, I figured 🙂 Even if you might not end up using it this way, I thought it would give you some ideas 🙂
