Wont render outside not inside

[GamebP]

I still have the same issue like last time from #7 . Maybe I need to change somere specific.
Changing NOTIFY_RENDER_OUTSIDE_MAIN_WINDOW to true it will not show it outside
But changing it to false will show in the menu

What branch of ImGui are you using? What backend is used for your app?

[GamebP]

Yesterday I changed to recent updated ImGui Docking.ocornut/imgui@7937732

[TyomaVader]

Could this be caused by an old DirectX version ?

[GamebP]

How to know witch one I am using?

[GamebP]

@TyomaVader I think you still have the viewing perms to my private project on my side. Maybe I don't know....

You're using DirectX 9 right now, it's pretty outdated, try upgrading to 11 or 12 from the Dear ImGui examples and check if this solves the issue

[GamebP]

Isnt d3d11 gonna break my project?

I don't think you're using any DirectX 9 specific functions, so updating ImGui backend and main.cpp files should be enough

[GamebP]

I'll try later

[GamebP]

idk,

[OlegSirenko]

Maybe try other backend like SDL? It's also not clear what code are you using for showing notifications. Are you enabled docking flag of ImGui?

io.ConfigFlags |= ImGuiConfigFlags_DockingEnable;         // Enable Docking
io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable;       // Enable Multi-Viewport / Platform Windows

[GamebP]

i am currently using d3d9

[GamebP]

doing this in d3d9, will be same

io.ConfigFlags |= ImGuiConfigFlags_DockingEnable;
io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable;

It show's a movable black imgui not the one i want to be moved from:

void gui::CreateHWindow(const char* windowName) noexcept
{
    windowClass.cbSize = sizeof(WNDCLASSEX);
    windowClass.style = CS_CLASSDC;
    windowClass.lpfnWndProc = WindowProcess;
    windowClass.cbClsExtra = 0;
    windowClass.cbWndExtra = 0;
    windowClass.hInstance = GetModuleHandleA(0);
    windowClass.hIcon = 0;
    windowClass.hCursor = 0;
    windowClass.hbrBackground = 0;
    windowClass.lpszMenuName = 0;
    windowClass.lpszClassName = "class001";
    windowClass.hIconSm = 0;

    RegisterClassEx(&windowClass);

    window = CreateWindowEx(
        0,
        "class001",
        windowName,

CreateHWindow creates and is only movable not the imgui menu

[OlegSirenko]

I do not really understand where is your problem. It is looks like this is not the ImGuiNotify trouble.

[GamebP]

its the d3d9 window creation issue 🤷

[GamebP]

I'm no expert in ImGui but somehow could fix it. @TyomaVader Can help me a little?
