如何检测鼠标右键按下？

Question

I want to detect right mouse button press in c++. I am programing in Linux OS.

I try to use XGrabPointer(display, root_win, False,ButtonPressMask, GrabModeSync, GrabModeSync, root_win, None, CurrentTime) and XWindowEvent(display, root_win, ButtonPressMask , &report) function for my project, but there is no answer.

My code is:

Display* display = NULL;
display = XOpenDisplay(NULL);
Screen *screen; Window root_win;
XEvent report;
int screen_num;
int check;

screen_num = DefaultScreen(display);
screen = XScreenOfDisplay(display, screen_num);
root_win = RootWindow(display, XScreenNumberOfScreen(screen));
check = XGrabPointer(display, root_win, False,ButtonPressMask, GrabModeSync, GrabModeSync, root_win, None, CurrentTime);
XAllowEvents(display, SyncPointer, CurrentTime); XWindowEvent(display, root_win, ButtonPressMask , &report);

您最常使用x11库。它非常简单（ http://www.wikihow.com/Configure-X11-in-Linux ）
