ubuntu下拦截鼠标事件, 使用x11编程,代码如下:
#include <stdio.h> #include <X11/Xlib.h> char *key_name[] = { "first", "second (or middle)", "third", "fourth", // :D "fivth" // :| }; int main(int argc, char **argv) { Display *display; XEvent xevent; Window window; if( (display = XOpenDisplay(NULL)) == NULL ) return -1; window = DefaultRootWindow(display); XAllowEvents(display, AsyncBoth, CurrentTime); XGrabPointer(display, window, 1, /*PointerMotionMask | */ButtonPressMask | ButtonReleaseMask , GrabModeAsync, GrabModeAsync, None, None, CurrentTime); while(1) { XNextEvent(display, &xevent); switch (xevent.type) { case MotionNotify: printf("Mouse move : [%d, %d]\n", xevent.xmotion.x_root, xevent.xmotion.y_root); break; case ButtonPress: printf("Button pressed : %s\n", key_name[xevent.xbutton.button - 1]); break; case ButtonRelease: printf("Button released : %s\n", key_name[xevent.xbutton.button - 1]); break; } } return 0; }
编译:gcc main.c -o mouse -lX11
注意:运行后鼠标将不能使用,关闭时使用键盘在终端输入ps -aux | grep mouse, 然后使用kill杀死mouse进程。
