全球鼠标在可可中移动事件 [英] Global Mouse Moved Events in Cocoa

问题描述

有没有办法在Cocoa中注册全局鼠标移动的事件？我能够使用Carbon的 InstallEventHandler（）注册事件，但是更喜欢Cocoa等价物。我找了 NSNotificationCenter 事件，但似乎没有任何公共活动名称（是否有私人活动？）

Is there a way to register for global mouse moved events in Cocoa? I was able to register for the events using Carbon's InstallEventHandler(), but would prefer a Cocoa equivalent. I have looked for NSNotificationCenter events, but there doesn't seem to be any public event names (are there private ones?)

或者，是否可以使用 NSTrackingArea 用于具有 clearColor 背景的视图？

Alternatively, is there a way to use NSTrackingArea for views with a clearColor background?

该应用程序只是雪豹。

推荐答案

在SnowLeopard有一个新类方法on NSEvent 这正是你想要的： +（id）addGlobalMonitorForEventsMatchingMask：（NSEventMask）mask handler：（void（^ ）block 。您将需要 mask = NSMouseMovedMask 。

In SnowLeopard there is a new class method on NSEvent which does exactly what you want: + (id)addGlobalMonitorForEventsMatchingMask:(NSEventMask)mask handler:(void (^)(NSEvent*))block. You’ll want mask = NSMouseMovedMask.
