@aayush Have you tried registering an onClosed or OnCloseRequest handler?

@edvin do you have a good way to update a TreeView? I have some code in populate() that builds a hierarchy of objects that I'd like to re-evaluate. Tried an event + refresh(), but the populate code isn't called.

refresh doesn't deal with the items. I don't use TreeView much, but let me check if I have some examples.

Oups, dinner on the table, back later!

Decoupling as described in https://thomasnield.gitbooks.io/rxjavafx-guide/content/10.%20Decoupling.html was the missing piece I was looking for.

@edvin you can always tag me if someone has an Rx question : ) @zealous so you're good now?

@thomasnield Thanks, will do next time :))

@thomasnield sorry for creating a github issue. I'm fine now.

@zealous no worries! I don't mind, I usually need things flagged with my name to notice it nowadays : ) And I don't mind that.

@edvin @Ruckus i was looking over #72...is there a kotlin way to do set divider positions on a splitpane or is everyone still making a setter call? splitpane { add(BrowserFragment::class) add(WorkareaFragment::class) vgrow = Priority.ALWAYS setDividerPositions( 0.3, 0.7 ) }

@carlw We don't have any special support. Can you imagine a nicer way to do it? Perhaps overloading

add

for

SplitPane

?

We could even allow something like

add<BrowserFragment> { dividerPosition = 0.3 }

dividerPositions = doubleArrayOf(0.3,0.7) ?

That doesn't help much compared to the JavaFX version does it?

no, i kind of like keeping it with the Fragment in the {}

Let me try to add that.

this might give us some inspiration for GridPane too

that is, keeping the layout associated with the object being operated on rather than associated with the container

...so you don't have to keep a separate set of vectors around that's away from the add() calls

It's kind of dirty, because this property will "only work" in some situations. But maybe that's fine.

some situations = when the parent is a SplitPane

I haven't tested it yet, but something like this might work:

@edvin uploaded a file: Untitled

Then we could add a version for UIComponent as well (Added it to the code sample above)

@aayush commented on @edvin’s file https://kotlinlang.slack.com/files/U0F3291QE/F77P5TLBZ/-.kt: @edvin I was using this code to change the background color of treetableview's child item. I already have a css written for treetableview

.custom-tree-table-header .column-header-background{
    -fx-background-color: rgba(255, 255, 255, 0.0);
}
.custom-tree-table-header .table-column{
    -fx-background-color: rgba(0, 0, 0, 0.4);
}
.custom-tree-table-header .label {
    -fx-text-fill: white;
    -fx-font-weight: normal;
}

.custom-tree-table-header .tree-table-row-cell{
    -fx-background-color: rgba(255, 255, 255, 0.0);
    -fx-text-fill: black;
    -fx-border-color: #b9bacc;
    -fx-table-cell-border-color:#b9bacc;
    -fx-border-width: 0.2px;
}
.custom-tree-table-header .tree-table-cell{
    -fx-background-color: rgba(255, 255, 255, 0.0);
}
.custom-tree-table-header .tree-table-row-cell:selected {
    -fx-background-color: #3f465d;
    -fx-table-cell-border-color: #3f465d;
    -fx-text-fill: white;
}

But as you can see in the gif the css breaks when the child item is selected because of the inline style

style{
                                        backgroundColor += Color.rgb(255, 255, 255, 0.3)
                                    }

The css works fine if I remove the setrowfactory part. Is there a way to add selection css for the child item?

@aayush If you inspect the components of the TreeTableView with Scenic View you will notice additional classes on the children, which you can use to set more specific styles based on selection. I think you'll find what you're looking for by opening up modena.css and looking at how the original styles are defined 🙂

I used the layout debugger https://cl.ly/1V33302A1I0v In that the child items and parent items have the same css class

There should be a selected pseudo class or something I think.

And probably not the column, but the cell.
