Linux： Embedded form cannot receive mouse events

Linux： Embedded window cannot receive mouse events

windows:Embedded window in Windows can receive mouse events, but cannot receive keyboard events

[niuzhaosen]

This is the focus window for Windows printing, and you can see that the keyboard focus has not been obtained

[niuzhaosen]

This is the focus window printed by Linux, and you can see that neither the keyboard focus nor the mouse focus has been obtained

SDL 2.30.8

[niuzhaosen]

I tried the latest 2.30.12 and the result is still the same

SDL_SetMouseFocus
SDL_SetKeyboardFocus
这两个方法能否对外暴漏呢

I believe this is fixed with SDL3.

[niuzhaosen]

我相信 SDL3 已经解决了这个问题。

Do you remember the question I asked you last time? Is there only one px embedded in the form on Linux? That's a bug in SDL3.
#11885

I mainly used the C # language to write the program, and sdl2 would have better support for C #. Can this be fixed in sdl2.
#12211
Observe the manifestation of sdl2 compatibility mode

`Sdl sdl = Sdl.GetApi();
sdl.CaptureMouse(SdlBool.True);
var window = sdl.CreateWindowFrom((void*)test.Handle);
var renderer = sdl.CreateRenderer(window, -1, (uint)RendererFlags.Accelerated);
System.Threading.Thread t = new System.Threading.Thread(() =>
{

while (true)
{
    Console.WriteLine("MouseFocus:" + (long)sdl.GetMouseFocus());                    
    int x = 0, y = 0;
    uint z = sdl.GetGlobalMouseState(ref x, ref y);
    Console.WriteLine(x + "-" + y + "-" + z);

    int x1 = 0, y1 = 0;
    uint z1 = sdl.GetMouseState(ref x1, ref y1);
    Console.WriteLine(x1 + "-" + y1 + "-" + z1);
    Event e = new Event();
    while (sdl.PollEvent(&e) != 0)
    {
        Console.WriteLine((EventType)e.Type);

    }



    System.Threading.Thread.Sleep(10);

}

});
t.Start();`

Under Windows, the mouse focus can be obtained normally, and getmousestate can obtain coordinates,
In Linux, the mouse focus cannot be obtained, and getmousestate cannot obtain coordinates, but GetGlobalMouseState can obtain coordinates

It seems to only appear when creating window from, and no exceptions were found when using create window

#157
This seems to be a legacy bug that existed a long time ago
