05/19/2021, 1:35 PMnope, dont think so - m

05/19/2021, 1:35 PMIf I set "value" to some value in a HBox, it actually works - m
most-caravan-45834
05/19/2021, 1:36 PMbut I wonder what real property gets set though - b
bright-gpu-74537
05/19/2021, 1:36 PMtext probably - m
most-caravan-45834
05/19/2021, 1:36 PMAigh, of course... indeed hbox has a value prop - m
most-caravan-45834
05/19/2021, 1:36 PMI remember using it for tabs - m
most-caravan-45834
05/19/2021, 1:36 PMHard to keep all of that in mind, but I'll get there eventually - b
bright-gpu-74537
05/19/2021, 1:37 PMok, yeah, that makes sense i guess value = text, and text is used in certain ways - m
most-caravan-45834
05/19/2021, 1:37 PMhopefully, with all this knowledge I'll be able to help other people here, at least - m

05/19/2021, 1:37 PMThanks a lot m8! - b
bright-gpu-74537
05/19/2021, 1:38 PMi would think about doing something like this: - b
bright-gpu-74537
05/19/2021, 1:38 PMCopy codehaxe class MyCustom extends HBox { @:clonable public var zoomLevel(get, set):Int; ... @:clonable @:value(zoomLevel) public var value:Dynamic; } - b
bright-gpu-74537
05/19/2021, 1:39 PMthen value == zoomLevel and you can "store" it there... i mean, nothing wrong with overriding the value ofc - b
bright-gpu-74537
05/19/2021, 1:39 PM(you dont really need the @:clonable either, but it means it will auto include that prop in the MyCustom.cloneComponent()) - m
most-caravan-45834
05/19/2021, 1:41 PMIn my case it's a little more complicated. zoomLeble:Int is not the actual value I want to expose through "value". But rather another Float value derived from it. But I realized I don't actually keep this derived value, I can always derive it to and from zoomLevel directly. - m
most-caravan-45834
05/19/2021, 1:41 PMSo I'm overriding value's setter and getter to change zoomLavel with an additional math - b
bright-gpu-74537
05/19/2021, 1:42 PMright, fair enough, should work totally fine, but you could also just create another prop and link value to that (there isnt a correct way btw, just pointing out options) - b
bright-gpu-74537
05/19/2021, 1:43 PMCopy codehaxe class MyCustom extends HBox { @:clonable public var zoomLevel(get, set):Int; @:clonable public var zoomLevelWithMath(get, set):Int; ... @:clonable @:value(zoomLevelWithMath) public var value:Dynamic; } - m

05/19/2021, 1:43 PMI actually talked about the issues, but did not say what I was doing 🙂 Maybe you have some insights into it. I'm creating a component similar to the example you used in the Custom Component guide - m
most-caravan-45834
05/19/2021, 1:44 PMIt's a increase and decrease button and a label - m
most-caravan-45834
05/19/2021, 1:44 PMbut I want the values to work like: ...1/4, 1/3, 1/2, 1, 2, 3, 4, 5, 6, 7... - m
most-caravan-45834
05/19/2021, 1:44 PMThat is what I want displayed in the label - m
most-caravan-45834
05/19/2021, 1:45 PMBut in value I want the actual float value of the expression, so 1/2 = 0.5, 1/4 = 0.25 and so on - b
bright-gpu-74537
05/19/2021, 1:46 PMshouldnt be an issue... two secs - m
most-caravan-45834
05/19/2021, 1:47 PMSo I'm keeping an internal _zoom: Int var that holds a value like: ... 1/4 = -2 1/3 = -1 1/2 = 0 1 = 1 2 = 2 ... And from this value I derive both "value" and label.text - b
bright-gpu-74537
05/19/2021, 1:48 PMthats how i would do i think - m
most-caravan-45834
05/19/2021, 1:49 PMI like to present the whole think, because you tend to surprise me with something already done that is almost what I want to do hahaha - m
most-caravan-45834
05/19/2021, 1:49 PMLike the example in the custom component guide being almost this already - m
most-caravan-45834
05/19/2021, 1:50 PMBut I see I'm on the right track! - m

05/19/2021, 1:50 PMThanks again! 🙂
