    What if there were more than 1 optional parameter with the same type?
  • m
    Btw, everything is working awesomely great
  • m
    Am I able to override the "set" of the "value" property?
  • m
    In other words I need internal side effects for the act of setting value from the outside of the component such as:
    Copy code
    haxe
var zoomSelector: ZoomSelector;
zoomSelector.value = 3;

    I wish I saw this like 2 hours ago lol. I'm still learning the heaps api, so I kept checking if I forgot to addChild the UI
  • b
    sure, you should just be able to override set_value, no?
  • b
    Heh heh, were you using the haxelib version and something wasnt there?
  • b
    Didn’t compile and I had to call ready myself lol
  • b
    right, you dont now though... correct?
  • m
    I tried to, not sure how I should do it though.
  • m
    Last attempt:
    Copy code
    haxe
public override function set_value(v)
{
  return v;
}
  • m
    But in all attempts I got:
    Copy code
    Field set_value overrides parent class with different or incomplete type
  • m
    When I try to follow super.set_value() but it leads to
    Copy code
    haxe
@:build(haxe.ui.macros.Macros.buildBehaviours())
  • b
    i guess you need to define the type? 
    set_value(value:Dynamic):Dynamic
  • b
    and yeah, .value is a "special" one as it means various different things depending on component
  • m
    I tried many things, but didn't try Dynamic
  • m
    Where is the value of "value" kept?
  • m
    _value?
  • m
    I mean, when I don't override the setter, the value is kept somewhere. but I can't do value = v; in the setter.
  • b
    Yeah the git version is all good
  • b
    value isnt "kept" anywhere, it leads to another property
  • m
    Oh I see. I'll keep it myself then
  • b
    yeah, thats one option...
  • b
    or you could have a another prop and use the haxeui macros... ie:
  • m
    But my question then is, if I don't override the getter, where does this value come from?
  • b
    from the other property, eg:
  • b
    Copy code
    @:clonable @:value(text) public var value:Dynamic;
  • b
    so when you call value, you are really calling text
  • b
    so the generated code for get_value will be something like:
    Copy code
    haxe
get_value() {
    return text;
}
  • m
    Does value refer to any property in a HBox?
