如何在应用程序未激活时观察键盘输入事件 [英] how do I observe keyboard input event while the applicaion is not actived

问题描述

解决方案

您需要创建一个CGEventTap使用 Quartz Event Services 。

如果您要设置一个热键，那么用户必须具有访问辅助设备的权限，这是有道理的。 ，碳事件管理器中有一个API ，以及一个名为SGHotKeysLib的Cocoa包装器。请注意，Carbon Event Manager热键API在当前的64位Mac OS X中仍然受支持。

解决方案

You'll need to create a CGEventTap using Quartz Event Services. The user must have access for assistive devices turned on, which makes sense, because that's the only legitimate reason for you to do that.

If you want to set up a hotkey, there's an API in Carbon Event Manager for that, and a Cocoa wrapper named SGHotKeysLib. Note that the Carbon Event Manager hotkey API is still supported in current, 64-bit Mac OS X.
