@permalmberg Can you shed some more light on the actual use case?

https://ronsmits.org/2017/02/idletimerinkotlin/ this is the kind of snippets I want to blog about

sounds more like you would want a datagrid or a listview instead of a scrollpane? @permalmberg

then you can add and remove using the listview api

<-- Back from dinner

@edvin @ron What I want to do is to add and remove shapes from the group. These shapes will be moved using the mouse.

The shapes are

Fragments()

built from various shapes, e.g.

rectangle

etc

I'm off to jiu jitsu in a bit, will take a look tonight if nobody beats me to it 🙂

@ron Remember that demo you showed me where you had something akin to the drawing-board of node-red? That's what I'm building

@edvin Enjoy 🙂

My network connection is a bit unreliable so I'm probably going to go off line any minute... Just @mention me and I'll see it on the phone and I'll log back in on the computer

Oh, interesting.

Btw, is there a tornadofx-way for drag and drop?

@permalmberg Not really, but if we can make it simpler we will 🙂

@edvin Ok

Gah, I can't get this drag-and-drop to work. Should'n't this be enough to handle a "drop"? Neither of the handlers fire...

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

                    setOnDragDropped {
                        fire(EndComponentCreation(group))
                    }

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

Apprently you have to use

setOnMouseDragReleased

instead....

@permalmberg there is drag and drop in that repo

@ron Thanks, got it working though.

but will have a look anyway

Hm, you're not using

onMouseDragReleased

I wonder why I have too? Perhaps because I use a

rectangle

as the target?

Will have to look into that more later

I bought a DVD without realizing I don't have a DVD player anymore

Haha, that's funny 🙂

Found an old laptop ripping it now

@permalmberg I use the onDragDropped, I think that is why I dont need the onMouseDragReleased

Question up!
