is there a way/feature where i can scale the whole UI like with -Dsun.java2d.uiScale for java gui?
some users report that things are too small, so that would help to have a setting like that for compose desktop

You can set LocalDensity for that

wow cool. do you have this example code online

[Zoff]

i meant that example from your screenrecording?

[Alexander Maryanovsky]

Not sure what you mean. It’s the settings window from an app I wrote.

[Zoff]

the weblink you posted has no mention of density

[Zoff]

can you post the kotlin code line that changes the density please?

[Alexander Maryanovsky]

It explains how to work with composition locals. LocalDensity is a composition local.

[Zoff]

i have no idea what that means. is there an example i can copy and paste? to change the density?

[Zoff]

does that i mean i have to set it on every component?

[Zoff]

i have a setting like in your screen recording. do you have an example of the code online which changes global density according to this float values?

[Akram Bensalem]

No, you just have to change the value of the LocalDensity

[Zoff]

ok. is there code sample i can copy and paste? LocalDensity has many entries

[Zoff]

how do i do that? LocalDensity is not writeable

[Sean Proctor]

CompositionLocalProvider(LocalDensity provides ...) { YourComponentThatNeedsToBeScaled() }

[Zoff]

@Sean Proctor cool that works. but it only changes on restart. how can i make it recompose when the value state changes? remeber by doesnt do it in that case

[Sean Proctor]

I'm not sure. It's probably something to do with the fact that LocalDensity is a StaticProvidableCompositionLocal. I guess you might need another way to cause the recomposition there.

[mohamed rejeb]

Make the density a compose mutableState @Zoff

[Marcin Wisniowski]

@Alexander Maryanovsky Is that a Compose Desktop EVE tool? I'm not alone with RIFT?!

[Alexander Maryanovsky]

It is 😄
