    Yeah, single time issue. Nevermind.
  • a
    there's an 
    onScroll
    event you can set on a scrollview
  • a
    maybe you could do some magic with that?
  • e
    Oh !
  • a
    scroll.onScroll = function (data) {}
  • a
    which uncovers a couple of actual scroll events
  • a
    you should be able to bind to those as well
  • e
    As the name suggests, it fires when the view is scrolled (mouse wheel, or setting the scroll value manually). It was worth the try, though :P
  • a
    ahhhhh
  • a
    could you not check if the scrollview changes
  • a
    but add some kind of bool
  • Scroll view
    a
    if (!justaddedcomponent) return; ... do stuff

    @early-butcher-76809 - i think you are looking for either of these: http://haxeui.org/builder/?e03820a7 ?
  • b
    (ie, 
    validateNow
    or 
    Toolkit.callLater
    ? )
  • b
    heh, nice... didnt get it at first, i was just like "isnt that just the haxeui logo"? Then i remember your original q
  • b
    alright, this is working now... now you can use layout / layoutName in xml (they both do the same thing now), also, you can use "layout" in css... this in fact was never working, it was never actually linked up (it is now)
  • b
    so property grids dont really support "any component", the components they support are based on the "type" (bool, int, etc)... that said, i think an action type might be nice...
  • b
    i also might investigate "any component", but i dont think its feasible since the component would have to be and IValueComponent (currently), though maybe that could change to InteractiveComponent... 🤔
  • b
    (actually, InterctiveComponent already implements IValueComponent... thats nice past me 🙂 )
  • f
    Awesome , thanks 🤟 it's funny I was convinced it had been working, because I had always thought it was such a cool feature 🙂 Now it will make it easier to have different designs for landscape/portrait/ different sizes.
  • b
    yeah, it was kinda interesting looking over the old layout code... some stuff is actually already implemented, like if you do 
    <box layout="vertical" layoutSomeProp="..." />
    it will actually generate code something like (this is the newer version of the code):
    Copy code
    haxe
var l0 = LayoutFactory.createFromName("vertical");
l0.someProp = "...";
c0 = new Box();
c0.layout = l0
  • b
    i left that being a possibility, but actually, there are no props (interesting ones anyway) on layouts... but its nice it was already basically implemented
  • f
    Oh interesting ... I have a few custom layouts. Maybe it could be useful. I wonder how custom layouts work with css/xml . I think there was something not implemenented. Hmmm, actually layout prop is super interesting. Like my usual custom layouts are usually like grid, vbox but from bottom to top, this kind of think. It makes it easier to make some super charged layouts.
  • b
    ok, so there is a limitation, which is that the result in LayoutFactory are hardcoded: https://github.com/haxeui/haxeui-core/blob/master/haxe/ui/layouts/LayoutFactory.hx#L5
  • b
    but this could be gotten from a module (like components are)... i wasnt thinking to implement it yet, because i assumed no one was using custom layouts
  • f
    Yeah, that what I was thinking of . I remembered the TODO 🙂
  • b
    do you have an example to hand of how you use custom layouts (just so we are on the same page)
  • f
    For example this uses a BottomGridLayout

  • b
    so it aligns dots (children) on a grid, but from the bottom?
  • f
    Exactly
