The default Value for the background color of a Box is transparent, right? I have generated a custom Material Theme with https://material-foundation.github.io/material-theme-builder/
How do i set the background color of a Box to the normal background ?

[Alexander Maryanovsky]

Box is a layout element. There’s no “default” background that it has; it just has no background unless you pass Modifier.background to it.

And no background means the color of the element 'below' is shown. But the the MaterialTheme function sets kind of normal background for the App. I want my Box to have that background color, to prevent showing elements that can be be dragged around my program. I hope my explanation is understandable.

The Box is the container for these play control buttons as shown in the screenshot below

You may want Surface

Yep

Modifier.background(MaterialTheme.colorScheme.surface)

solved it.

Next question: does Compose Desktop respect OS/Desktop enviroment setting for darkmode/lightmode? In my case Linux/KDE.

Or must this be configured manual by the user?
