[bug] Context.GetPlatform().GetContentScale() is missing in v0.8.0

[xEricL]

What happend?

In v0.7, I used Context.GetPlatform().GetContentScale() to scale a progress bar. However, it appears GetPlatform() has been removed in v0.8.0 in this commit.

What is the alternative?

Code example

main.go

I was using

giu.SingleWindow().Layout(
	giu.Align(giu.AlignCenter).To(
		giu.Dummy(0, scaleDivider(6)),
		giu.ImageWithRgba(logoI).Size(LogoSize, LogoSize),
		giu.Dummy(0, scaleDivider(6)),
		giu.ProgressBar(ReadProgress()).Size(scaleValue(WindowWidth)*0.75, scaleValue(5)),
	),
)

where scaleDivider and scaleValue were defined as

func scaleDivider(value float32) float32 {
	scale := giu.Context.GetPlatform().GetContentScale()
	if scale > 1.0 {
		value *= 2
	}
	return value * scale
}

func scaleValue(value int) float32 {
	scale := giu.Context.GetPlatform().GetContentScale()
	return float32(value) * scale
}

To Reproduce

1. Update to v0.8.0
2. Try to build project that was previously using giu.Context.GetPlatform().GetContentScale()

hi, GetScaleFactor was a part of imgui-go api.
Now, we check scale as follows:
(MasterWindow.go)

        // Scale DPI in windows
        if runtime.GOOS == "windows" {
                xScale, _ := Context.backend.ContentScale()
                imgui.CurrentStyle().ScaleAllSizes(xScale)
        }

go get access to Context.backend try using cimgui.CurrentBackend

go get access to Context.backend try using cimgui.CurrentBackend

Can you please give a code example? I'm having trouble finding cimgui.CurrentBackend.

[gucio321]

Because, as i just realized, it doesn't exist hehe 😅
ill add giu.Context.Backend later

• see add Context.Backend() method that returns currently used cimgui-go ba… #811

I suppose this is fixed, lmk if you still need help.

⚠️ If you use ScaleAllSizes, this is IMPORTANT ⚠️

Take a look at the following things:

• [bug] Window grows until filling screen then app crashes #810
• master window: fix DPI scaling #812
