在C ++中移动鼠标指针在Linux上失败 [英] Moving the mouse pointer in C++ fails on Linux

问题描述

我使用以下代码隐藏和显示鼠标光标：

I'm using the following code to hide and show the mouse cursor:

XDefineCursor( m_display, m_window, show ? None : m_hiddenCursor );  
XFlush( m_display );

这很好。但是，当我运行这个：

That works fine. However, when I run this:

XWarpPointer( m_display, None, m_window, 0, 0, 0, 0, x, y );
XFlush( m_display );

鼠标根本不移动。只是没有发生。 SetMousePos，我用于Windows，工作正常。

The mouse doesn't move at all. Simply nothing happens. SetMousePos, which I'm using for Windows, works fine.

推荐答案

这是一段时间，但XWarpPointer 相对使用传递的偏移量移动光标？看起来像传递的偏移量是（0,0），意味着光标不会移动。我想你要使用的例程是XMovePointer。

It's been a while, but doesn't XWarpPointer make a relative move of the cursor using the passed offsets? It looks like the passed offsets are (0,0) meaning that the cursor wouldn't move. I think the routine you want to use is XMovePointer.
