C ++ - 在X窗口中更改光标 [英] C++ - change the cursor in an X Window

问题描述

我认为这很容易找到，但google搜索已经非常无益。有没有简单的api更改鼠标光标在你的X窗口？ （我知道在Windows中你可以调用SetCursor）

I thought this would be easy to find, but a google search has been very unhelpful. Is there a simple api to change the mouse cursor in your X window? (I know in windows you can just call "SetCursor")

推荐答案

#include <X11/cursorfont.h>

/* ... */

Cursor c;

c = XCreateFontCursor(dpy, XC_xterm); 
XDefineCursor(dpy, w, c);

其中dpy是您的显示，w是您的窗口，XC_xterm是一个常数，定义光标的形状。以下是可用光标形状的列表，以及图片。

Where dpy is your display, w is your window and XC_xterm is a constant defining the shape of your cursor. Here's a list of available cursor shape, along with images.
