Let me give you the bigger picture

I'm trying to pull off a color picker

The problem is, a change say in the red slider, should provoke a change in the red textfield

And a change in the red textfield should provoke a change in the red slider

There are all sorts of interactions like that

sure, and you are saying they screw with each other?

And also I'm having a hard time figuring out why im running in infinite validation loops sometimes

actually the problem is infinite loops

where on change will trigger the change on the other and so on

this seems fine

... ... wonder if its a haxeui-openfl issue...

Is there a way to get more information on validation loops?

which properties are being altered, etc?

or which components?

not really, i mean, you could trace out info i guess, but nothing inbuilt

maybe a flag could be useful...

ok, I'll bang my head a little more 🙂

Hey @bright-gpu-74537 , this line by itself, is causing a validation loop

haxe
saturationSlider.value = _pickedColor.saturation * 100;

I fixed it with:

haxe
saturationSlider.value = Std.int(_pickedColor.saturation * 100);

But I don't understand why this workaround works, or the original line doesn't

Is there difference between this and the following?

haxe
mySomething.onChange = null;
mySomething.value = 100;
mySomething.onChange = callback;

Because I tried the later and it didn't work, because the onChange event was being triggered after the last line.

In my case, I'm only interested in listening to changes made by the user using the interface, not side effects caused by the code. Is there a specific event for that?

I've managed to work around everything. Now I've got a ColorPicker fully working :), but the code would be way neater if I could listen to user user UI interface changes only. For the moment, I've worked around using this:

haxe
class CallbackHandler
{
    public var action(get, never): UIEvent -> Void;
    public var ignoreNext: Bool;

    private var _action: UIEvent -> Void;

    public function new(action: UIEvent -> Void)
    {
        this._action = action;
    }

    public function get_action()
    {
        return (e: UIEvent) ->
        {
            var temp = ignoreNext;
            ignoreNext = false;
            
            if (!temp)
                _action(e);
        };
    }
}

and then

haxe
redTextfield.onChange =         _callbackMap.get(redTextfield).action;
redSlider.onChange =             _callbackMap.get(redSlider).action;
greenTextfield.onChange =         _callbackMap.get(greenTextfield).action;
greenSlider.onChange =             _callbackMap.get(greenSlider).action;
blueTextfield.onChange =         _callbackMap.get(blueTextfield).action;
blueSlider.onChange =             _callbackMap.get(blueSlider).action;
hueTextfield.onChange =         _callbackMap.get(hueTextfield).action;
hueSlider.onChange =             _callbackMap.get(hueSlider).action;
hueMainSlider.onChange =         _callbackMap.get(hueMainSlider).action;
saturationTextfield.onChange =             _callbackMap.get(saturationTextfield).action;
saturationSlider.onChange =             _callbackMap.get(saturationSlider).action;
brightnessTextfield.onChange =             _callbackMap.get(brightnessTextfield).action;
brightnessSlider.onChange =             _callbackMap.get(brightnessSlider).action;
alphaTextfield.onChange =         _callbackMap.get(alphaTextfield).action;
alphaSlider.onChange =             _callbackMap.get(alphaSlider).action;
hexTextfield.onChange =         _callbackMap.get(hexTextfield).action;

Then, whenever I want to change values in code, I set respective ignoreNext to "true"

is there an event or callback for a dialogue closing on haxeui-hxwidgets?

Trying to do a file browse dialogue where, on a file being selected, the path is put into a text box next to it. Problem is that while I can do

if (dialog.show()) { ... }

that only happens when the dialogue opens

I can't find a

callback

property or something like

onClose

closest I can find is

dialog.endModal(retCode:Int):Void

but that requires me to force a particular return code rather than get it
