Global Mouse Hook和SetWindowPos

问题描述

大家好。

现在，我正在尝试开发桌面应用以重新定位窗口。

我使用Global Mouse Hook和SetWindowPos来重置窗口的位置。

首先我通过SetWindowHookEx安装了LowLevel Mouse Hook（WH_MOUSE_LL，MouseProc，Null，Null）

MouseProc是回调函数。

它的声明是这样的：  LRESULT CALLBACK MouseProc（int code，WPARAM wParam，LPARAM lParam）

wParam here

与鼠标消息有关。

我在WM_LBUTTONUP中使用了SetWindowPos（）函数。只需单击鼠标左键就可以正常工作。 

但是当我将鼠标移动和鼠标左键单击组合时，它的效果很奇怪。

问题是窗口捕捉到原始位置，这是在执行SetWindowPos（）之前的位置。

我认为这取决于系统窗口的拖动，我不确定。 / p>

请建议您的想法。

感谢您的帮助。

Hi, Everyone.

Now, I'm trying to develop the desktop app to re-position the window.

I used Global Mouse Hook and SetWindowPos to reset the position of the window.

First I installed LowLevel Mouse Hook by SetWindowHookEx(WH_MOUSE_LL, MouseProc, Null,Null)

MouseProc is callback function.

Its declaration is like this:   LRESULT CALLBACK MouseProc( int code, WPARAM wParam, LPARAM lParam)

wParam here

is about Mouse Message.

I've used SetWindowPos() function in WM_LBUTTONUP. It works well when I simply click the mouse left button. 

But When I combined mouse move and mouse left button click, it works strange.

The problem is that the window snap into original position which is position before SetWindowPos() was executed.

I think that it's up to system window dragging and I'm not sure.

Please suggest your ideas about it.

Thanks for your kind help.
