在Windows上获取鼠标光标位置和按钮状态 [英] Getting mouse cursor position and button state on Windows

问题描述

在Windows(Windows 7及更高版本)上获取鼠标光标位置或按钮状态的最合适方法是什么?我以前使用过DirectInput，但是我不再使用它，也不希望这样做.我看到有GetCursorPos，但是，没有看到任何有关获取鼠标按钮状态的信息.以前，我已经读过，对于实时应用程序而言，仅读取窗口消息(例如WM_LBUTTONUP)被视为慢速"，因此我不知道任何其他选项.

What is the most appropriate way of getting the mouse cursor position or button state on Windows (Windows 7 and above)? I previously used DirectInput, but I am not longer using it and do not wish to. I saw there is GetCursorPos, however, I do not see anything for getting mouse button states. I have read previously that just reading the window messages (such as WM_LBUTTONUP) was considered "slow" for real time applications, so I do not know of any other option.

推荐答案

如果要轮询/查询当前光标位置，可以使用 GetAsyncKeyState .

If you want to poll/query the current cursor position, you can use GetCursorPos. To see the button states, use GetAsyncKeyState.

如果您正在窗口中实现消息循环，则鼠标移动的通知将为此处.

If you are implementing a message loop in a window, the notification you will get for a mouse movement is WM_MOUSEMOVE. You will be notified of mouse inputs through the notifications listed here.
