X11和XLib-键盘输入不正确

为了解决X11和XLib中键盘输入不正确的问题，可以通过在代码中使用XInternAtom和XSetWMProtocols函数来设置XSelectionOwner消息，从而确保获取焦点和正确处理键盘输入。

示例代码如下：

Display *dpy; int screen; Window root, win; Atom wm_delete; Atom clipboard;

/* Connect to X server */ dpy = XOpenDisplay(NULL); if (dpy == NULL) { fprintf(stderr, "Cannot connect to X server\n"); return 1; }

/* Get the root window */ screen = DefaultScreen(dpy); root = RootWindow(dpy, screen);

/* Create a window */ win = XCreateSimpleWindow(dpy, root, 0, 0, 400, 300, 0, 0, WhitePixel(dpy, screen));

/* Set WM_PROTOCOLS property to handle window deletion */ wm_delete = XInternAtom(dpy, "WM_DELETE_WINDOW", False); XSetWMProtocols(dpy, win, &wm_delete, 1);

/* Set _NET_WM_NAME property */ XStoreName(dpy, win, "My Window");

/* Set _NET_WM_WINDOW_TYPE property */ Atom net_wm_window_type = XInternAtom(dpy, "_NET_WM_WINDOW_TYPE", False); Atom net_wm_window_type_normal = XInternAtom(dpy, "_NET_WM_WINDOW_TYPE_NORMAL", False); XChangeProperty(dpy, win, net_wm_window_type, XA_ATOM, 32, PropModeReplace, (unsigned char *)&net_wm_window_type_normal, 1);

/* Set clipboard owner */ clipboard = XInternAtom(dpy, "CLIPBOARD", False); XSetSelectionOwner(dpy, clipboard, win, CurrentTime);

/* Map the window and wait for events */ XMapWindow(dpy, win);

XEvent event; while (true) { XNextEvent(dpy, &event); switch (event.type) { case ClientMessage: if (event.xclient.message_type == wm_delete) { /* Handle window deletion / XDestroyWindow(dpy, win); XCloseDisplay(dpy); return 0; } break; case SelectionClear: / Handle selection clear event / break; case SelectionRequest: / Handle selection request event / break; default: / Handle other events */ break; } }
