Slider crashes with 'Null object reference'

[kevansevans]

OpenFL backend, using master branch of haxeui-core and haxeui-openfl.

Expected Behavior

A new slider should be made without any hiccups.

Current Behavior

Creating a new Slider causes a null object crash

Possible Solution

Finish this function here so it doesn't return null: https://github.com/haxeui/haxeui-core/blob/379289399ef424a4389418b58ab198adcef68467/haxe/ui/components/Slider.hx#L267

Steps to Reproduce (for bugs)

Create new openFL project. Use master branches of both haxeui-core and haxeui-openfl Write anything that lets you instantiate a new slider. haxe.ui.components.Slider; Compile to Windows/CPP. Use -debug flag to get error box. Program crashes with no warning otherwise.

Context

I need a horizontal slider. Can't use a horizontal slider if it crashes.

Your Environment

Windows 10 desktop. Using HaxeDevelop IDE. Using windows/cpp as target. Both latest OpenFL and Lime versions. Haxe 4 RC3

Thanks, this is a perfect repro.

HorzionalSlider should be used (same goes for any "directional" controls). Note when using xml, this is required, you can use:

<slider direction="vertical|horizontal" /> and the macro will build the correct class name for you. I do wonder though if it might make sense to have a default impl, like "Slider" being a horizontal slider. Ill have to think about it.

In the mean time, can this be closed?

Cheers, Ian

Yes, this can be closed. Apologies for the late reply.
