C ++ Win32设置光标位置 [英] c++ win32 set cursor position

问题描述

我知道要使用哪个功能，但无法正常使用。我使用 SetCursorPos（）唯一的问题是它不会将光标设置为Windows坐标，而是设置为屏幕坐标。我还尝试了 ScreenToClient（），但是它在道德上没有用。

这是我的代码：

I know which function to use but I can't get it to work right. I used SetCursorPos() the only problem is that it sets the cursor not to the windows coordinates but to the screen coordinates. i also tried the ScreenToClient() but it didn't work ethier.
Here is my code:

pt.x=113;
pt.y=280;
ScreenToClient(hWnd, &pt);
SetCursorPos(pt.x, pt.y);

有什么想法吗？
我正在使用win32。希望我能提供足够的信息。

any idea? I'm using win32. I hope that I given enough information.

推荐答案

您正在稍微退步。 SetCursorPos 函数可在屏幕坐标中使用，您想根据窗口/客户端坐标设置光标。为此，您需要从客户端映射到屏幕坐标。函数 ScreenToClient 则相反。您要查找的是 ClientToScreen

You're approaching this slightly backwards. The SetCursorPos function works in screen cordinates and you want to set the cursor based on window / client coordinates. In order to do this you need to map from client to screen coordinates. The function ScreenToClient does the opposite. What you're looking for is ClientToScreen

例如：

ClientToScreen(hWnd, &pt);
SetCursorPos(pt.x,pt.y);
