Is there built-in support for drag-to-resize panels? Haven't been able to find anything about it on google.

afaik no, but can be easily done with dragging modifier, look at the code-viewer example at jb-compose repo

[David W]

thank you!

[David W]

i'm constantly surprised at how easy it is to build new components

[David W]

(but also somewhat frequently surprised at how many are missing - i had to homeroll a datagrid, for example, but it is 1.0 after all, more will come later, especially in third-party libs)

[David W]

I'm realizing that I should have spent a few hours reading the samples before embarking on this three-month desktop compose app...

[David W]

and just like that, it's done

By the way, there is a built-in SplitPane compenent https://github.com/JetBrains/compose-jb/tree/master/components/SplitPane

[Thomas]

You can include it in gradle using compose.desktop.components.splitPane

[David W]

oh huh. that's kind of an arbitrary place to find it. thank you

[David W]

think i'll stick with what's already working, especially since i don't see a super convenient callback to use to update my config file with the user preference

[David W]

ended up switching and simply updating the config file when a child recomposes. probably not ideal but it works

Not sure why you want to update a “config file”. At least you should wrap it in a SideEffect.

[Thomas]

Oh you want to save and restore the percentage when you restart the app. Is that right?

[David W]

yeah, or simply navigate away from the screen and back

[Thomas]

In that case maybe you could do something like:

LaunchedEffect(splitterState.positionPercentage) { /* TODO: update the config */ }

[Thomas]

Just an idea, not sure if this is the best way though

[David W]

yeah that's better, thank you
