c - 如何在 Linux 上的 C 中设置鼠标光标位置？

Question

如何在 Linux 下使用 C 程序设置 X 窗口中的鼠标 光标位置？谢谢 :)(类似于 WIN 中的 setcursorpos())

编辑:我试过这段代码，但不起作用:

#include <curses.h>

main(){
 move(100, 100);
 refresh();
}

12.4 - Moving the Pointer

Although movement of the pointer normally should be left to the control of the end user, sometimes it is necessary to move the pointer to a new position under program control.

To move the pointer to an arbitrary point in a window, use XWarpPointer().

示例:

Display *dpy;
Window root_window;

dpy = XOpenDisplay(0);
root_window = XRootWindow(dpy, 0);
XSelectInput(dpy, root_window, KeyReleaseMask);
XWarpPointer(dpy, None, root_window, 0, 0, 0, 0, 100, 100);
XFlush(dpy); // Flushes the output buffer, therefore updates the cursor's position. Thanks to Achernar.
