< Zach Klippenstein he him MOD > has an implementation of an arbitrary marquee modifier floating around

Simon Stahl · Answer

I would love to see that slightly smiling face I assume it did not make its way into the official libs yet

Adam Powell · Answer

I don t think it has any dependencies on internals so whether it s in the official libs or not yet shouldn t matter

It s in my queue to land once I m done fixing a few critical text field bugs sweat smile

Simon Stahl · Answer

looking forward to it I couldn t get it to work copying the files from the PR because `Modifier transformLayoutCoordinates ` is unknown it s ok though i got another custom implementation that does work until your changes get merged in

You only need that if you need touch input in your marquee content

Simon Stahl · Answer

ah i see I got it to work after commenting out that code but am a bit surprised about how the marquee seems to work 1 I would expect a short pause after every marquee loop when the text reaches its original position 2 The text is marquee ing even when it fits inside 3 The marquee is backwards unless I specify a negative speed 4 Ideally there would be some fading on the edges so the text doesn t look so cut off

Simon Stahl · Answer

this is how i use it ```val speed = 30 dp val spacing = 50 dp val marqueeState = rememberScrollingMarqueeState dpsPerSec = speed Text modifier = Modifier fillMaxWidth marquee state = marqueeState spacing = spacing text = it maxLines = 1 ```

Simon Stahl · Answer

is this by design or did i mess something up when commenting out some of the code

Zach Klippenstein (he/him) [MOD] · Answer

This is all useful feedback for the api Most of it was intentional you have full control of the animation you can add whatever pauses you want You can also add fades or other effects if desired A lot of these things might be specific to a particular design system so it might not make sense to provide all these behaviors automatically in Foundation I m actually not sure if Material includes Marquee if it did it could be built on top of this

Simon Stahl · Answer

OK i ve played around with it for a bit but couldn t quite figure out how to achieve it Are there any more examples except what is in `MarqueeSamples` and `MarqueeDemo` I wonder if since marquee text is probably the default case folks are looking for it would make sense to include a shortcut for this case

Simon Stahl · Answer

What I am looking for is something that behaves similar to this `TextView` and can be configured in a similar way ```TextView context apply layoutParams = ViewGroup LayoutParams ViewGroup LayoutParams WRAP CONTENT ViewGroup LayoutParams WRAP CONTENT text = The quick brown fox jumped over the lazy dogs isSingleLine = true ellipsize = TextUtils TruncateAt MARQUEE marqueeRepeatLimit = 1 isHorizontalFadingEdgeEnabled = true isSelected = true textAlignment = View TEXT ALIGNMENT CENTER ```

Yea it probably makes sense to provide something that matches the framework behavior at the very least as a sample but probably even as code
