kotlinlang #compose-desktop

I'm trying to implement something that enables undecorated Compose Window to utilize native window features, like snapping, dragging, resizing. I'd already implemented it(in fact mostly copy-pasted) and seems to work, but it implements its hit test by itself. I want it to utilize hit test logic from Compose UI. How can I do that? Note: I cannot sure if it is called on the UI thread, I only know that it is called from the listener passed to SetWIndowLongPtrA(hwnd, GWLP_WNDPROC, this one).

is there a way to make the titleBar support dark mode?

@xxfast I found the Transparent Window code you might like to look at: https://github.com/JetBrains/compose-jb/blob/master/tutorials/Window_API_new/README.md#transparent-windows-eg-allows[…]make-windows-of-a-custom-form

Why does setting icon size change text width/wrapping in a DropdownMenuItem?

DropdownMenuItem(
                            onClick = {...}) {
                                Icon(
                                    painter = painterResource(item.iconPath),
                                    modifier = Modifier.padding(end = 4.dp),//.size(24.dp),
                                    contentDescription = null
                                )
                                Text(
                                    text = item.text
                                )
                            }
                        }

.size

commented out = left, wrapped. not commented out = right, not wrapped. This is on Compose

1.1.0-rc01

, but also happens on

1.0.1

Question: What's the best way to keep a vertically scrollable Text object, whose content is always added to, always scrolled to the bottom by default? Thanks!

Curious question about Skiko implementation: Why the JNI implementation is written in C++ and not exposed by Kotlin Native? I saw couple examples using KN for JNI. I'm looking to understand that because I'm starting a library multiplatform that will require JNI for JVM.

Hello all, I'm stumped trying to get a

Text

object's contents in a

@Composable

to update when a global String variable changes. I have a global String

var dataIn = ""

that regularly fills with characters like

data += char

in one function, but I can't get its value change to recompose the displayed

Text

in the other function! I thought it should be doable using

var dataDisplay: String = remember { mutableStateOf(dataIn) }

and

Text(text = dataDisplay)

but it won't update the text display every time a new char is added to the

dataIn

variable. Thanks again!

Also, how do you handle trying to call a

@Composable

function from a

Window()

MenuBar

??? I can't do it from a

Window

in the

main

function, as that can't be

@Composable

, and a

@Composable

can't be called from anything but a

@Composable

? But a

Window

in a

@Composable

function still can't seem to do it! Sorry! Thanks! 🥴

It seems

Modifier.focusable(false)

doesn’t work on buttons. I took the first focus example from https://github.com/JetBrains/compose-jb/tree/master/tutorials/Tab_Navigation and added a button at the bottom:

TextButton(
    onClick = { println("Clicked") },
    modifier = Modifier.focusable(false)
){
    Text("Click me")
}

and the button still participates in focus navigation, and when it has focus and I press ENTER, it prints “Clicked”. Is it a bug or am I misunderstanding what

focusable(false)

should do?

I’m trying to create a

Column

with a

VerticalScrollBar

that grows with its contents until it reaches the maximum available space and then becomes scrollable. The code looks approximately like this:

Box{
    Column(
        modifier = Modifier.verticalScroll(scrollState)
    ) {
        ...
    }
    VerticalScrollbar(
        modifier = Modifier.align(Alignment.CenterEnd).matchParentSize()
    )
}

Without the scrollbar, it works fine. Unfortunately, as soon as I add the scrollbar, it stretches the

Box

to fill all the available height. It doesn’t seem to respect the

matchParentSize

modifier.

Hello! what column layout I use so that the wrapped rows is vertical scrollable ,I tried

LazyColumn

, but not compiling.Such as:

LazyColumn(
    //
){
    mutableStateArrays.forEachIndexed { index, value ->
        Row(
            modifier = Modifier.padding(top = 10.dp),
            horizontalArrangement = Arrangement.Center
        ) {
            OutlinedTextField(
                //
            )
            DropdownMenu(
                //
            ) {

Is it possible to override the Compose compiler version? I’m currently testing Kotlin 1.6.20 and Google provides a special build for the Compose Compiler

1.2.0-dev-k1.6.20-RC-21f332eaa05

. Does Jetbrains provide a similar build for Desktop?

If my CfD app folder is siblings with a folder named

jre

that contains a jre, the exe appears to try to use that JRE instead of the one in the exe's folder.

./ComposeApp/app.exe
./jre/bin/java.exe

It crashes before even getting to my Main method, and running it from cmd outputs:

C:\Program Files (x86)\Fractal Softworks\Starsector\SMOL_Dist> .\SMOL.exe

Error: could not open `C:\Program Files (x86)\Fractal Softworks\Starsector\jre\lib\jvm.cfg'

(not that the

jre

folder is

../jre

, relative to the exe) If I move the application folder anywhere else, it runs fine. If I rename

jre

to anything else, it runs fine. Anyone have any ideas as to what could be causing this? I don't want it to have any interaction with that jre folder, it's pure coincidence that many users are placing it next to a

jre

folder.

In this thread I will be teasing out Compose for Desktop with code coverage. The strategy is to let IntelliJ generate the Hello, Desktop basic app and then add infrastructure to eventually get a sensible code coverage report for this trivial app.

The IntelliJ version information is: IntelliJ IDEA 2021.3.1 (Ultimate Edition) Build #IU-213.6461.79, built on December 28, 2021 Licensed to Argus / Paul Reilly Subscription is active until October 1, 2022. For non-commercial open source development only. Runtime version: 11.0.13+7-b1751.21 aarch64 VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o. macOS 12.2.1 GC: G1 Young Generation, G1 Old Generation Memory: 2048M Cores: 10 Non-Bundled Plugins: com.intellij.nativeDebug (213.6461.6) org.jetbrains.kotlin (213-1.6.10-release-944-IJ6461.79) Statistic (4.1.7) Kotlin: 213-1.6.10-release-944-IJ6461.79

Using defaults, the app builds and runs without a hitch and generates the expected output (after clicking on the button):

Next step is to add the Kover plugin to the build script:

id("org.jetbrains.kotlinx.kover") version "0.4.2"

A Gradle run of the clean and build tasks is successful at doing nothing. Next step is to add a Kover configuration, borrowing from another project so that the kover configuration is:

kover {

isEnabled = true

coverageEngine.set(kotlinx.kover.api.CoverageEngine.INTELLIJ)

intellijEngineVersion.set("1.0.622")

generateReportOnCheck.set(true)

Another clean, build Gradle run still is successful at doing nothing. Hmmm. that is a surprise that nothing different happened ... my expectation was that kover would run and complain that nothing was covered. Next step is to figure out why there is no report and why Gradle thinks that the report is up-to-date. Hmmm. If you've been following along and have some idea about what is wrong, do tell. I'll be back when I figure out the answers to those two questions.

Ah, that was easy. There were no tests. Adding a simple test to do nothing works and a report is generated. I'll take a break here to go generate a YouTrack issue that IntelliJ ought to generate basic, really simple, tests for Compose Multiplatform.

Next, I added a simple test and created a Gitlab project for this thread. As you can see from the attached screen shot, the test passes but also throws an exception. I am still struggling trying to explain the exception in an actionable way. Looks very much like a Compose Multiplatform bug. @olonho or @Igor Demin would you agree?

I have this error on Compose 1.0.0, but don’t have on Compose 1.1.0

pajatopmr

03/08/2022, 7:04 PM

Good to know. It also raises the questions: should a bug report be filed on 1.0.0 or should 1.1.0 be preferred. My preference is the latter.

Igor Demin

03/08/2022, 7:31 PM

1.1.0 is released, so no need in bug report

pajatopmr

03/09/2022, 6:19 AM

Preferring the Compose plugin version 1.1.0 actually generates a valid coverage report. Hallelujah! But to get there, the following build and code changes were required (and have been pushed to the Gitlab repo mentioned above):

And that's a successful wrap for this thread.
