Hey, im creating a desktop application with compose multiplatform, and im having issues applying a theme.
Im using material3 components, using the generated AppTheme + colors.
Some elements like cards and buttons get colored, but the background of the window is white and all text is statically black.
Isnt it supposed to color that automatically as long as i wrap everything in my AppTheme, forcing useDarkTheme to true?

[Alexander Zhirkevich]

It happens when you mix same-named M and M3 composables. Make sure all of your components are actualy imported as material3.

[Sven Wollinger]

Im pretty sure thats already the case:
Only icons are still there, which shouldnt be an issue right?

[Sven Wollinger]

Do Composables like "Column" count? If so, how do i switch them to m3?

[Sven Wollinger]

Maybe im not wrapping everything correctly then?
I got this hirachy:
Button -> Column -> Window -> AppTheme
Is this correct?

[Alexander Zhirkevich]

Have you tried placing AppTheme inside Window?

[Sven Wollinger]

Yeah, tried wrapping my column in it too, sadly no change

[Sven Wollinger]

Not even the Text is changing the color to something light, even though im using the M3 Version

[Sven Wollinger]

This is inside my window:

AppTheme(useDarkTheme = true) {
    Column(
        modifier = Modifier.fillMaxSize()
    ) {
        Text("About OneGit v${build.version}")
    }
}

[Sven Wollinger]

Comes out like this

[Alexander Zhirkevich]

Is behaviour the same when you wrap your column with Scaffold or Surface?

[Sven Wollinger]

holy cow i knew i was missing somethihng

[Sven Wollinger]

So sorry. Thank you for your help. Thats it.

[Sven Wollinger]

I was going mad. I knew i was missing something from the last time i (probably) had to figure out the same thing again

[Alexander Zhirkevich]

Those components are requred to apply correct background and content color

[Sven Wollinger]

Yeah no makes perfect sense. Thank you :)

[Sven Wollinger]

short follow up, is it possible to set the Window Theme under windows?

[Sven Wollinger]

Outside of Windows Settings i suppose

[Alexander Zhirkevich]

What do you mean by window theme?

[Sven Wollinger]

The Title Bar, not sure what its called in the lower level

[Sven Wollinger]

Thats probably statically dictated by the users settings in windows, yeah?

[Alexander Zhirkevich]

Title bar color is not a trivial change. You can try it with AWT look&feel. I use https://github.com/JetBrains/jewel (another way)

[Sven Wollinger]

Oh yeah, i actually remember using something for a swing application of mine. Maybe i can somehow inject that, thank you 🙂 Great pointer already
