我在正确设置 glfw 覆盖层时遇到了一些问题，我已经成功创建了一个具有透明背景的 glfw 窗口，现在我想让该窗口也“点击通过”，这样我就可以访问它后面的窗口并让它像一个覆盖。

遗憾的是我不知道如何在 glfw 中执行此操作，我当前初始化窗口的代码如下所示：

Width = 3440;
Height = 1440;
/* GLFW */
if (!glfwInit()) {
    fprintf(stdout, "[GLFW] failed to init!\n");
    exit(1);
}
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
glfwWindowHint(GLFW_DECORATED, GLFW_FALSE);
glfwWindowHint(GLFW_RESIZABLE, GLFW_FALSE);
glfwWindowHint(GLFW_FOCUSED, GLFW_FALSE);
glfwWindowHint(GLFW_FOCUS_ON_SHOW, GLFW_FALSE);

/*Topmost and see through*/
glfwWindowHint(GLFW_FLOATING, GLFW_TRUE);
glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE);

glfwSwapInterval(1);
Window = glfwCreateWindow(Width, Height, "Overlay", 0, 0);
glfwMakeContextCurrent(Window);

我还尝试使用 glfw3_native.h 给出的 glfwGetX11Window 函数并尝试做类似的事情

void Render::MakeClickable(bool State){
    auto X11Window = glfwGetX11Window(Window);
    if(State){

    }else{
        XserverRegion region = XFixesCreateRegion (MainDisplay, NULL, 0);
        XFixesSetWindowShapeRegion (MainDisplay, X11Window, …
