我到 http://tronche.com/gui/x/xlib/event-handling/XSendEvent.html网上面看了下有关XSendEvent()的说明，可我就是不能得到我想要模拟键盘的效果,我把代码发给大家看看.软键盘的界面是我用java swt做的，现在它功能要用低层C来实现。我原来的想法是从java里面得到哪个按键被触发，然后我在把该key对应在linux下的key value(比如XK_1)扔到这个方法里面，然后再把要发送的焦点windowID也扔进去。这样就可以模拟键盘的输入效果。可我都试了好几天没怎么用。哪个能指点我下哦。 我本来是做JAVA的可要用到地层的没办法。C都忘了差不多了 我看那xvkbd 软键盘源码看的我头痛死了。如果哪个也看了哪个的话帮忙说下那结构大概是怎么样，我只想知道它是怎么向窗口发送事件的，界面实现部分我不需要懂因为我用java实现了。下面是我自己根据那源码自己想写个键盘事件模拟接口但是实现不了那功能郁闷 #include "Setchar.h" #include <X11/Xlib.h> #include <X11/Xutil.h> #include <X11/Xatom.h> #include <X11/Xos.h> #include <X11/cursorfont.h> #include <stdio.h> #include <signal.h> #include <stdlib.h> #include <unistd.h> #include <ctype.h> #include <string.h> #include <errno.h> #include <time.h> #include <X11/Intrinsic.h> #include <X11/StringDefs.h> #include <X11/Shell.h> #include <X11/keysym.h> #include <X11/cursorfont.h> #include <X11/Xproto.h> /* to get request code */ #include <X11/Xaw/Box.h> #include <X11/Xaw/Form.h> #include <X11/Xaw/Command.h> #include <X11/Xaw/Repeater.h> #include <X11/Xaw/Label.h> #include <X11/Xaw/MenuButton.h> #include <X11/Xaw/SimpleMenu.h> #include <X11/Xaw/SmeBSB.h> #include <X11/Xaw/SmeLine.h> #include <X11/Xaw/AsciiText.h> #include <X11/Xaw/Viewport.h> #include <X11/Xaw/List.h> #include <X11/Xmu/WinUtil.h> #include <X11/extensions/XTest.h> #include <X11/Xlocale.h> Window focus_window; Display *display; int screen_num; KeyCode keycode; static struct KeyMapEntry { char *config; KeySym keysym; } keymap[] = { {"Escape", XK_Escape}, {"Backspace", XK_BackSpace}, {"1", XK_1}, {"2", XK_2}, {"3", XK_3}, {"4", XK_4}, {"5", XK_5}, {"6", XK_6}, {"7", XK_7}, {"8", XK_8}, {"9", XK_9}, {"0", XK_0}, {"Up", XK_Up}, {"Down", XK_Down}, {"Left", XK_Left}, {"Right", XK_Right}, {"Enter", XK_Return}, {"Shiftr", XK_Shift_R}, {"Shiftl", XK_Shift_L}, {"Ctrlr", XK_Control_R}, {"Ctrll", XK_Control_L}, {"Space", XK_Right}, {"CapsLock", XK_Caps_Lock}, {"Tab", XK_Tab}, {"F1", XK_F1}, {"F2", XK_F2}, {"F3", XK_F3}, {"F4", XK_F4}, {"F5", XK_F5}, {"F6", XK_F6}, {"F7", XK_F7}, {"F8", XK_F8}, {"F9", XK_F9}, {"F10", XK_F10}, {"F11", XK_F11}, {"F12", XK_F12}, {"q", XK_q}, {"w", XK_w}, {"e", XK_e}, {"r", XK_r}, {"t", XK_t}, {"y", XK_y}, {"u", XK_u}, {"i", XK_i}, {"o", XK_o}, {"p", XK_p}, {"[", XK_P}, {"]", XK_P}, {"a", XK_a}, {"s", XK_s}, {"d", XK_d}, {"f", XK_f}, {"g", XK_g}, {"h", XK_h}, {"j", XK_j}, {"k", XK_k}, {"l", XK_l}, {";", XK_l}, {"'", XK_Right}, {"z", XK_z}, {"x", XK_x}, {"c", XK_c}, {"v", XK_v}, {"b", XK_b}, {"n", XK_n}, {"m", XK_m}, {",", XK_Right}, {".", XK_Right}, {"/", XK_Right}, {"`", XK_Right}, {"psc", XK_Print}, {"slk", XK_Scroll_Lock}, {"brk", XK_Pause}, {"ins", XK_Insert}, {"hm", XK_Home}, {"pup", XK_Page_Up}, {"del", XK_Delete}, {"end", XK_End}, {"pdn", XK_Page_Down}, {"nlk", XK_Num_Lock}, {"!", XK_Right}, {"@", XK_Right}, {"#", XK_Right}, {"$", XK_Right}, {"%", XK_Right}, {"^", XK_Right}, {"&", XK_Right}, {"*", XK_Right}, {"(", XK_Right}, {")", XK_Right}, {"_", XK_Right}, {"+", XK_Right}, {"|", XK_Right}, {"\\", XK_Right}, {"=", XK_Right}, {"-", XK_Right}, {"\"", XK_Right}, {":", XK_Right}, {"?", XK_Right}, {">", XK_Right}, {" <", XK_Right}, {"keymenu", XK_Menu}, {"metal", XK_Meta_L}, {"metar", XK_Meta_R}, {"Altl", XK_Alt_L}, {"Altr", XK_Alt_R} }; /* void set_input_hint(Display *dispay, Window w, Bool bInput) { XWMHints *wm_hints; wm_hints = XGetWMHints(display, w); wm_hints->flags |= InputHint; wm_hints->input = bInput; XSetWMHints(display, w, wm_hints); XFree(wm_hints); } */ void dispatchEvent(char *msg) { printf("\naaafff=%s\n",msg); XWMHints *wm_hints; struct KeyMapEntry entry; int i; if ( (display=XOpenDisplay(NULL)) == NULL ) { printf("-2\n"); fprintf( stderr, "winman: cannot connect to \ X server %s\n", XDisplayName(NULL)); exit(-1); } printf("-1\n"); screen_num = DefaultScreen(display); printf("0\n"); focus_window = RootWindow(display, screen_num); printf("1\n"); wm_hints = XGetWMHints(display, focus_window); printf("2\n"); wm_hints->flags |= InputHint; printf("3\n"); wm_hints->input = False; printf("4\n"); XSetWMHints(display, focus_window, wm_hints); printf("5\n"); XFree(wm_hints); for ( i = 0; keymap .config; i++) {
