@ron there was a typo though

dot not

During a nice talk in the tornadoFX slack channel one of the members noticed that his Fragments were being added to the view he was working on, but they

dot not

receive any event(like onDock). The reason was that he manually instantiated the fragments:

I'll fix it after dinner

@ron If you only had my Hugo Editor, you'd push it with

Ctrl-Alt-S

😁

If only

Haha 🙂

Howdy folks

@edvin Using find<>() for the views turned out really well. It actually forced me to further separate view and ViewModel, which is a good thing

@ron Re. your blogpost, you say that Yes all Views, ItemModels and Controllers are Singletons but that isn't supposed to be true for

Fragment

unless I'm misstaken? Sure, if you do

by inject()

I guess it becomes a singleton, but since that isn't the idea with a

Fragment

the statement becomes somewhat confusing.

No a fragment is not a singleton

It is meant to be used in several places

the typo is fixed

I like hugo 🙂

Actually, I might just be reading too much into the word Views

but thank you for sharing your experiences @permalmberg it was the basis for the blog post

No problem 🙂

I'm just happy I have somehere to ask for help 🙂 If more people can benefit from my questions, then that is awesome

the development of tornadoFX is going so fast it was time it got some blog post with tips and tricks in it

@ron agree... I always forget about http://kotlinlang.slackarchive.io/tornadofx/ also...

On another topic: I'm strugling with local- vs scene-relative coordinates. I have a simple class inheriting from `javafx.scene.shape.Line`:

class WireView(source: OutputView, target: InputView) : Line()

I want to bind the `startX/Y `and

endX/Y

properties to another view so that the ends of the line moves when the other view. As such, in the other view (a

Fragment

) I do:

override fun bindPosition(wire: WireView) {
        wire.endXProperty().bind( root.layoutXProperty())
        wire.endYProperty().bind( root.layoutYProperty())
    }

The binding in it self seems to work, but the problem is that

root.layoutX

is local to that

Fragment

. Is there an easy way to transform the local coordinate system to that of the view that the

Fragment

is contained by? As I type this, I remember reading about using a converter for bindings, perhaps that is the way?

@permalmberg Glad to hear it! Did you end up passing a ViewModel as param instead?

@permalmberg would the relocate() method help?

There are methods for `Node`s like

localToScene

and

localToParent

I use it in LayoutDebugger to draw an overlay over a node which belong to a separate hierarchy, like this:

@User uploaded a file: Untitled

So basically,

localToScene

will give you scene coordinates if you pass in

boundsInLocal

.

This object dragging code code uses Scene coordinates for the overall positioning and localToParent to capture the placement of the mouse within the shape.

@permalmberg here's a link to a sandboxed JNLP if you want to see if the dragging action fits what you're doing with wire view
