Haxe

because some backends can only do things like that async

i am coming to the realisation more and more with every passing day that the things i do with my computer are different to what most people do with their computers

well, in browser you have to load an image from data... thats an async operation (of course)

(openfl, nme too - and likely others i cant think of off hand)

```haxe
@:dox(icon = "/icons/ui-layered-pane.png")
@:composite(Builder)
class Stack extends Box {
    @:behaviour(SelectedIndex, -1)      public var selectedIndex:Int;
    @:behaviour(SelectedId)             public var selectedId:String;
    
    @:call(PrevPage)                    public function prevPage();
    @:call(NextPage)                    public function nextPage();
    
    public function new() {
        super();
    }
}
```

well, treectrl in hxwidgets coming along nicely 🙂

i think i prefer wxDataViewTreeCtrl (left)

feels a little more modern... api is a little bit more of a pain, have to see how well haxeui integ goes

```haxe
removeChild(dropdown);
        removeChild(fixDescription);
        dropdown.y = description.y + description.textHeight + 20;
        dropdown.width = Math.min(110, w - SIDEBAR_WIDTH - 10) + 10;

        fixDescription.x = Math.min(110, w - SIDEBAR_WIDTH - 10) + 15;
        fixDescription.y = dropdown.y;
        fixDescription.width = Math.max(180, w - SIDEBAR_WIDTH - dropdown.x - fixDescription.width);
        fixDescription.height = fixDescription.textHeight + 4;
        addChild(dropdown);
        addChild(fixDescription);
```
this piece of code is triggered whenver the window is resized

and this is whats happening:

so what happens when you remove the removeChild / addChild?

removeChild doesnt remove the removed child from the screen

when removing the child addition & removal, only the text updates

hmmm, doesnt sound right / normal... is this an app i can run this end?

yep, just clone the repo and build for sys:
