Is it possible to use BooleanArray in checkbox ? about imgui HOT 14 CLOSED

I use KTX in my project, you can check out if you want : https://github.com/Catvert/Platform-Creator
Have a look at this project too : https://github.com/Catvert/Imgui-test, its a simple example with LibGDX but without kTX but you can adapt the code easily.

I found the problem, nothing is drawn unless I call:

if (ImGui.drawData != null) LwjglGL3.renderDrawData(ImGui.drawData!!)

However, I have a JavaVM crash after 10s, it occurs even if I call only LwjglGL3.newFrame()

crash log (hs_err_pid4212.log): https://pastebin.com/cV5hKTbR

the interesting part of the log seems to be:

Yes, a short explanation is here here (but I'll add it in the wiki)

This is the appBuffer object.

It's thread-safe and fast because you pay only a single allocation overhead at begin of your app and then one clear per frame. From there any "allocation" is just dummy, that is a call to intAtomic

Basically it's suitable for any short-live native allocations, included OpenGL and Vulkan native resources, as well as GLFW. Plus anything else the user may ever need

It gets automatically called if you use the window.loop { }, otherwise you have to do it manually

Ps: you should also call it in the reshape, because if the user start resizing the window dragging for a time long enough he will fill it up

Thanks a lot for the support !

Hi!

unfortunately that is not possible. It'd be cool, but there seems to be no way at the moment.

But we can simply pass the array itself with an index.

checkbox(value.name, enum1ArrayEnabled, index)

I just pushed, give it a look

from imgui.

I used imgui-kotlin 1.53 and lwjgl 3.1.5
I moved to imgui-kotlin master and lwjgl 3.1.7

But now, I have the following error at run : Caused by: java.lang.Error: No current context. Did you call ImGui::Context() or ImGui::setCurrentContext()?

I add a context creation but imGui is not displayed anymore:

class Application : KtxGame<Screen>() {
    private val context = Context()
    private var contextImGui: imgui.Context? = null

    override fun create() {
        val window = GlfwWindow((Gdx.graphics as Lwjgl3Graphics).window.windowHandle)
        contextImGui = imgui.Context()

        LwjglGL3.init(window, false)

        context.register {
            bindSingleton<Viewport>(ScreenViewport())
            bindSingleton<Batch>(SpriteBatch())
            bindSingleton(Stage(inject(), inject()))
            bindSingleton(this@Application)
            bindSingleton(Game(inject(), inject()))
        }

        addScreen(context.inject<Game>())
        setScreen<Game>()
    }

    override fun dispose() {
        contextImGui?.destroy()
        LwjglGL3.shutdown()
        super.dispose()
    }
}

In more had a compilation error that I remove for now (imgui.IO.wantCaptureMouse is not anymore recognized)

from imgui.

That Error is thrown whenever gImGui is still null when you want to use imgui to render some gui

Theoretically, after you instantiate the imgui.Context(), gImGui shouldn't be null anymore. Check that

wantCaptureMouse is there, I have no idea why you can't see it

from imgui.

gImGui is initilialized.

Do you know why the imGui window is not displayed?

from imgui.

It's very hard to know why without having access to some code.

What I can suggest you, is to start from the tests and then build it up from there

from imgui.

I understand but I really would like to use Ktx...

Here is my build.gradle and standalone file sample app (maybe it would be nice to add it as test app):

@Catvert I have the same crash on your project https://github.com/Catvert/Platform-Creator

I don't have it on Imgui-test

I use JDK 1.8

from imgui.

Try add appBuffer.reset() in your loop

I'll expand the wiki soon about that

from imgui.

It works !

But it is a good practice to reset the buffer each frame?

from imgui.

I'll close it, if it's fine for you
