问题描述
我正在寻找一种方法来在用户输入设备具有一维滚动轮或二维trackPad/magicMouse的情况下在[NSResponder scrollWheel:]
中可靠地区分?
I am looking for a method to reliably distinguish within [NSResponder scrollWheel:]
if the users input device has a one-dimensional scroll-wheel or a two dimensional trackPad/magicMouse?
首先,我想实现一种不同的行为.但是,仅查看NSEvent
的deltaX会有些薄弱.有什么建议吗?
In the first I would like to implement a different behavior.But just taking a look on the deltaX of the NSEvent
would be a little weak.Any suggestions?
推荐答案
您可以使用私有方法调用[theEvent _scrollPhase]
来判断设备是否正在使用惯性滚动,这表示Apple提供的输入设备. (注意:如果用户禁用了惯性滚动,则此功能将无效)
You can use the private method call [theEvent _scrollPhase]
to tell whether the device is using inertial scrolling, which indicates an Apple-supplied input device. (Note: this won't work if the user has disabled inertial scrolling)
