Committed a fix.

@gtnarg

runLater

Will work for me

Node has a

needsLayoutProperty

Maybe you can listen to it until it fires once, then deregister your listener? I wonder if we should have a construct that does this automatically.

onFirstChange

for example.

@User uploaded a file: View Composed of 2 Fragments + ViewModel and commented: Indirect updating of one Fragment from another

@gtnarg the above Kotlin file demonstrates what I was talking about in the chat yesterday with you...use the ViewModel to drive the Fragment display data rather than a direct method call

@edvin If you get a chance, could you review the Kotlin file I just posted? most interested in your take on the binding calls in the builders and the selection logic

@gtnarg If I get a chance today, I'll add in the Model which would be a RESTful, UI-neutral class that would be invokved by a ui/async when the viewModel.refresh() is called In these calls, I use the event bus "back channel" to let the ViewModel know that something new is available. The ViewModel can then make a RAM-based call to get the items (they'll be there already) to fill up the ListView.

@carlw If you can share the rest that would be great. Thank you for taking the time to share them.

@jchildress Unfortunately, my Kotlin coding was cut short this morning with snow shoveling

🙂

I can't imagine... it's cold here in Houston for us... no snow though...

Z-Order - anyone got some tricks up their sleeve regarding that? Sorting things in the scene graph seems so cumbersome...

@permalmberg you're using a Pane w. absolute positioning or a StackPane with layers?

@carlw Stackpane with layers:

override val root = scrollpane {
        stackpane {
            group {
                rectangle {
                    layoutX = 0.0
                    layoutY = 0.0
                    width = 5000.0
                    height = 5000.0
                    fill = Color.LIGHTGOLDENRODYELLOW
                }.apply {
                    rect = this
                }

                setOnMouseDragReleased {
                    fire(EndComponentCreation(it.sceneX, it.sceneY))
                }

                setOnDragOver {
                    it.acceptTransferModes(TransferMode.COPY)
                }
            }.apply {
                group = this
            }
        }
    }

Items are added to the

group

@permalmberg are you trying to transfer an object from one layer to another? ex, change the parent?

@carlw No, I want my lines do be drawn under the black squares components. But they can be created in any order. (see my image above)

@carlw Will do. Dinner now, then I need to buy a new sledge, we just got snow 🙂 hehe I'll check it ASAP.

@carlw Just checked, I have some nice improvement suggestions 🙂 Coming soon!

@carlw But if I understand you correctly - what you're saying is that I should use different parents for different parts

@carlw I suppose that could work if I use transparent colors for all but the bottom layer

@permalmberg I am kind of late to understanding exactly what you want. And I don't have a code sample to help you. But if you are "just" working on connecting nodes and moving them, the following post helped me in the past.

@edvin If you want to do another code review / critique with this code, feel free

Again, I apologize that I don't have a working example I can point you to right now.

@permalmberg and the post is for JavaFX not TornadoFX, but maybe it could help.

@jchildress thanks, but I think I think I have that part figured out, now I'm just trying to make it look the way I want

@jchildress Your attention is still appreciated

@permalmberg I'm suggesting a single parent for all graphical objects (composite objects aside)

@carlw Yup!
