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。
