Hello.
I tried to work hello-ktx sample according to README in this project. But it doesn't work and output this error.

My os version is
CentOS Linux release 7.6.1810 (Core)

Please give me a hint. Thanks

With Kotlin 1.3 the support for raspberry was added (which is a linuxArm32Hfp plattform).
It would be great to extend the project for this platform.

I already compiled the libui manually and added it, but it should be done directly in this project instead of doing it manualy.

Hi, me again. :)

I've noticed the dispose() method is never called for me in the examples.
I've tried hello-ktx and controlgallery, OS is Manjaro (4.19 Kernel).

The callback from uiOnShouldQuit is never reached.

Even when I dispose the mainWindow manually, I would have expected all children's dispose() method to be called - which was not the case!

I'm not sure if I missed something, or maybe it's a bug?

Hi, this is awesome!

Is there an easy way to add kotlin-libui as a dependency when I create a new project, or does kotlin-libui have to be in the parent gradle project?

I found OpenFileDialog very useful and would like to have the same for folders. If you don't have time for it I can try to dig into it.

Can we display links?

When executing an application created with this library on linux, it looks for libcrypt.so.1 which on Arch Linux has been deprecated and replaced with libcrypt.so.2. This issue can be solved simply by creating a symlink, which means theres no compatibility issues requiring the older version of the library, so I would recommend updating the dependency to the newer version.

I noticed in this project's README that you weren't sure about the DSL.

Well, what if we changed the DSL over to Android/Jetbrains Compose? It seems like fun idea because:

• Take advantage of the tree-building and reactivity built into compose
• Compose is gaining traction & mind-share, so this project might be more approachable by sharing concepts
• Improved code sharing; e.g. you could use expect/actual to build common interfaces that work across both Android and native desktop.
• Jetbrains is already working on Compose Desktop, but some devs (myself included) disapprove of using Skia canvas instead of native platform widgets for reasons of accessibility/etc.. Plus, it's on the JVM and not Kotlin/native. So we could create a nice alternative to fill a different niche.

I'm just brainstorming, but I'm hoping to have some time to explore this myself, thought the idea was worth sharing.

https://github.com/msink/kotlin-libui/tree/master/samples/drawtext

Namely I wonder how the text is written, so that it appears like
that. Could the readme there briefly explain how this is done?

I am reading the source code but I am still a kotlin noob so ...

libui/libui.def

-linkerOpts.linux = -L/usr/lib/x86_64-linux-gnu \
+linkerOpts.linux = -L/usr/lib \

Not sure if this can be set automatically to the correct directory on all systems. Maybe just document somewhere that you might need to adjust the value?

gradle.output.txt

How could we choose a file or dir in libui, or is there any way to achieve this goal?

Looks like I am missing a library?

Need to integrate coroutines support from
https://github.com/Kotlin/kotlinx.coroutines/tree/master/native
and add sample similar to timer but based on coroutines.

This is awesome that you've put this project together and continue to maintain it. I'm trying to think of an easy way to add it to an app, and it's not an easy process. It'd be amazing if this were on maven central so we could pull it naturally as a dependency!

Did you guys have a look at libui-ng yet?

https://github.com/libui-ng/libui-ng

Hi, one more thing ;)

I've seen files like this: https://github.com/msink/kotlin-libui/blob/5f1c615a6fa1ba846fb1e910a76fe26ff44e19cf/samples/table/src/main/resources/andlabs_16x16test_24june2016.png.kt

They look like they are generated from the png file, and I'm interested how you generated them.

Is the generator part of the repo? And is it possible to extract the generation of the files as a step in the gradle-build?

Asked from K/N developers: JetBrains/kotlin-native#1624

I'm trying to run a background task using a worker and display a message when an exception is caught.

Here's a minimal reproducible example:

package example

import kotlin.native.concurrent.TransferMode
import kotlin.native.concurrent.Worker
import libui.ktx.*

fun main() = appWindow("Test", 800, 600) {
    vbox {
        button("Test") {
            action {
                Worker.start().execute(TransferMode.UNSAFE, {}) {
                    MsgBox("This doesn't work")
                }
            }
        }
    }
}

That fails with this error when clicking the button:

Do you plan to support some kind of data-binding?

I think of it in a way that you pass a model object (Observable?) to a TextField, and each time the string is changed, the UI is changed as well.

And, additionally, each time the user types into the TextField, the model object get's changed automatically.

Need to investigate why.

These would be a welcome addition to the DSL, as the tornadofx has them and they're handy
https://github.com/edvin/tornadofx/wiki/Forms

I saw this sample, but it doesn't work for the ComboBox and probably others.

I'm thinking about writing applications that run natively, but also on the JVM.
Is it possible to write one single gui code, using the kotlin-libui syntax ?
Can the kotlin-libui library be extended, so it uses e.g. Tornado-FX, but still provide the same programming interface to the developer?

For now there is almost no documentation, except for autogenerated.
Any contributions will be very helpful.

As Kotlin 1.3.31 now can build for 32-bit windows - I decided just switch windows build to 32-bit, and drop support for 64-bit windows, at least for now.
Do not see any reasons for 64-bit windows executable for simple utilites.
If anyone have significant reasons - please comment here, and I will create new target windows_x64

To migrate - just replace in your build scripts mingwX64 to mingwX86, and msys2-mingw-w64-x86_64-gcc-7.3.0-clang-llvm-lld-6.0.1 to msys2-mingw-w64-i686-gcc-7.4.0-clang-llvm-6.0.1.
Gradle should be upgraded to 5.4 - gradle wrapper --gradle-version 5.4 --distribution-type all

So new projects can just use kotlin-libui as a normal dependency

See #7

Not sure if it is macOS only and if it is blocked by upstream. But I couldn't find any issue/info in the upstream libui project.

Right click -> copy works though.

Hi,
I'm using this library to build a desktop project but I need to close the window manually and re-create it later. Now I'm using the ktx library but I cannot find any methods to do this. Are there any methods for me to use in order to close the window? My code is attached below. Thanks.

fun main(args: Array<String>?) {
    appMain() // Display the UI and block
    // To do some extra work.
}

fun appMain() = appWindow(
    title = "Sample",
    width = 320,
    height = 240
) {
    vbox {
        button ("Quit") {
            action {
                // uiControlDestroy
                // I tried it but the window closes without continuing the statements in main().
                this@appWindow.dispose()
            }
        }
    }
}

Despite two years have passed since the moment when this problem had been outlined for the first time, there is still no documentation.
I'm a newbie to both Kotlin|NAtive and GUI.
I found that I simply cannot do even the simplest things without documents.

Can anybody assist me in providing at least full-functional (and not few simple samples) examples of coding GUI using libui?
I need to build a very simple application:

1. Initialize window
2. Initialize menu
3. Input several common project data (the algorithm is to check the input and do not allow incorrect data)
4. Output these data to the screen
5. Switch to the next screen
6. Input several particular project item data
7. Output them to the table on the screen
8. Perform calculations.
9. Switch to the next screen
10. Output the results to the screen
11. Calculate one more version?
12. If Yes - goto 6
13. If No - do nothing

Thank you.
