Hello, I currently face performance issues with LazyVerticalStaggeredGrid. When I display 1 column then scrolling is quite fast, but if I make it more than 2 then fps drops to like 1 fps. I tried to optimize it but no success so far. It is running in release mode as well

is there a simple way to have drag and drop from other applications? i want to be able to drag a file from a filemanager into a componont of my app. the component should visually change so that the user can see its a possible drop target. and the i need to get the filename

Hi, I am working on an AutoCompleteTextView/ExposedDropdownMenuBox in Jetpack compose for Desktop. For some reason with my current implementation whenever I get a lot of items from my API returned the DropdownMenu overlaps with my TextField, how can I prevent this behaviour? I have already tried to calculate the height of the screen and subtract the TextField height but without much success. Is there a way I can force my Dropdown to always be below the TextField, maybe with some kinds of menuAnchor() behaviour like Android has?

@Composable
fun TextFieldWithDropdown(
    modifier: Modifier = Modifier,
    value: String,
    onValueChange: (String) -> Unit,
    options: List<String>,
    onOptionClick: (String) -> Unit,
) {
    val density = LocalDensity.current

    var text by remember {
        mutableStateOf(value)
    }

    var expanded by remember(options) { mutableStateOf(options.isNotEmpty()) }

    var anchorSize by remember {
        mutableStateOf(DpSize.Zero)
    }

    Box(modifier) {
        TextField(
            modifier = Modifier
                .fillMaxWidth()
                .onGloballyPositioned {
                    anchorSize = with(density) {
                        DpSize(
                            width = it.size.width.toDp(),
                            height = it.size.height.toDp()
                        )
                    }
                }
                .onFocusChanged { focusState ->
                    if (!focusState.isFocused) {
                        expanded = false
                    }
                },
            singleLine = true,
            value = text,
            onValueChange = {
                text = it
                onValueChange(it)
            },
            colors = TextFieldDefaults.textFieldColors(
                backgroundColor = MaterialTheme.colors.surface,
                textColor = MaterialTheme.colors.onSurface,
                cursorColor = MaterialTheme.colors.onSurface,
            ),
        )


        DropdownMenu(
            modifier = Modifier
                .width(anchorSize.width),
            offset = DpOffset(0.dp, Dimens.normal),
            focusable = false,
            expanded = expanded,
            onDismissRequest = { expanded = false }
        ) {
            options.forEach { text ->
                DropdownMenuItem(
                    onClick = {
                        onOptionClick(text)
                    }
                ) {
                    Text(text = text)
                }
            }
        }
    }
}

Hi all, I am trying to make my desktop app dark theme aware. Right now I am struggling to make the title bar follow the system theme. For macOS It works perfect by adding this argument in my gradle file:

macOS {
    jvmArgs(
        "-Dapple.awt.application.appearance=system"
    )
}

Is there some equivalent setting to also make it work on Windows? Or maybe some other way to set it in code?

Hopefully this is helpful to somebody, I have created a library to workaround the fact the Desktop previews in IntelliJ are half-baked and in general very limited respect to the Android ones. In future, I might think of writing a wrapper of the IntelliJ Preview plugin to use it via an annotation. Here's the library, hope somebody will enjoy and please leave feedback via issues! https://github.com/alexfacciorusso/compose-previewer

hallo everyone, is there a way to track composition count for different composables in multiplatform?

What would be a proper way to set a minimum size for a

Window

? I want my window to be resizeable, but squishing it into a tiny square is not useful, so I'd like to set a reasonable minimum. If the minimum size could just be based on minimum measurements of the Compose layout, that would be even greater.

Hey, I am trying to dynamically resize my Window based on state changes, for example, I have a "collapse" mode where a large chunk of the UI is hidden and then I want the Window size to fit the contents. I have tried about a billion approaches now, and every time I get close, it sometimes messes up the layout as can be seen in the included screenshot (see how the content is moved to the bottom left, the black screen is my bounds). When I try to resize the window when this happens, it restores the right size. So I am wondering if there is a way to force composed to recalculate all the layouts based on a window size change.

I try to publish my macOS JVM app on Testflight and get an error
