如何钩住OS X字典 [英] How to hook the OS X dictionary

问题描述

在osx狮子，你可以控制命令d或三击你的鼠标指向任何应用程序中的字，以启动一个popover字典。我想让一个应用程序来跟踪用户在字典中查找的字词。

on osx lion, you can control-command-d or triple-tap on a word that your mouse is pointed to in any app to launch a popover dictionary. i want to make an app to track the words a user is looking up in the dictionary.

我如何观察用户执行control-command-d的事件三次点按以启动popover字典？

how do i observe the event where the user does control-command-d or triple-tap to launch the popover dictionary?

我知道这个特定的API是 HIDictionaryWindowShow 。

I understand that the specific API for this is HIDictionaryWindowShow.

推荐答案

可以使用 popoverDidShow：

- (void)awakeFromNib {
    NSNotificationCenter* notificationCenter = [NSNotificationCenter defaultCenter];
    [notificationCenter addObserver:self selector:@selector(popoverDidShow:)
                            name:NSPopoverDidShowNotification object:nil];
}

// dictionary is shown or another NSPopover
- (void)popoverDidShow:(NSNotification*)notify { 
    //your code
}
