在Linux中使用xGrabPointer锁定鼠标指针 [英] Locking mouse pointer using xGrabPointer in Linux

问题描述

我正在使用X11来获取在没有任何窗口的终端上运行的应用程序中按下鼠标按钮时的鼠标位置.

I am using X11 to get mouse position when the mouse button is pressed in a application which runs on terminal without any window.

获取鼠标位置:

Display *dpy;
Window root, child;
int rootX, rootY, winX, winY;
unsigned int mask;
dpy = XOpenDisplay(NULL);
XQueryPointer(dpy,DefaultRootWindow(dpy),&root,&child,
             &rootX,&rootY,&winX,&winY,&mask);

现在，我想使用XGrabPointer()锁定鼠标，以使其不与桌面上存在的对象(窗口，图标和底座)交互. 此处是XGrabPointer的文档，但我似乎不太明白如何使用它，传递什么参数.

Now I want to use XGrabPointer() to lock the mouse so that it does not interact with objects(windows , icons and docks ) present on desktop . here is the documentation of XGrabPointer , but I don't seem to understand how to use it and what arguments to pass .

推荐答案

这是似乎对我有用的正确格式.

This is the correct format that seems to work for me .

int g=XGrabPointer(dpy,DefaultRootWindow(dpy), true, ButtonPressMask |
                 ButtonReleaseMask |
                 PointerMotionMask |
                 FocusChangeMask |
                EnterWindowMask |
                  LeaveWindowMask,GrabModeAsync,GrabModeAsync, None, None, CurrentTime);
