在Mac OS中监控剪贴板 [英] Monitor clipboard in Mac OS

问题描述

我需要在我的mac os应用程序监视剪贴板事件。我找到了剪贴板查看器和另一个问题在stackoverflow要求同样的事情，但没有人有一个解决方案如何监视剪贴板事件。

I need to monitor clipboard events in my mac os app. I found a sample for a clipboard viewer and another question in stackoverflow asking for the same thing, but none of them has a solution on how to monitor the clipboard events.

也就是说，在用户点击命令+ c后，我立即得到一个事件通知。我知道该功能存在，因为有一个应用使用此功能功能

That is, immediately after the user hits command + c, I get an event notifying. I know that the functionality exists, as there is an app that uses this functionality

想法？

推荐答案

它会打印输入到剪贴板的每一个基于文本的信息]看到下面的代码：

I have written a clipboard listener [it will print every new text based information that entered the clipboard] in native Java see the following code:

import java.awt.Toolkit;  
import java.awt.datatransfer.*;  
import java.io.IOException;  

public class ClipboardListener extends Thread implements ClipboardOwner {

    Clipboard systemClipboard = Toolkit.getDefaultToolkit().getSystemClipboard();  

    public void run(){  
        Transferable selection = systemClipboard.getContents(this);  
        gainOwnership(selection);  
        while (true) {}
    }  

    public void gainOwnership(Transferable t){ 
        try {this.sleep(100);} 
        catch (InterruptedException e) {}
        systemClipboard.setContents(t, this);  
    }  

    public void lostOwnership(Clipboard clipboard, Transferable contents) {
        try {System.out.println((String) clipboard.getData(DataFlavor.stringFlavor));} 
        catch (UnsupportedFlavorException e) {} 
        catch (IOException e) {}
        gainOwnership(contents);  
    }  
}

public class myApp {

    public static void main(String[] args){
        ClipboardListener listener = new ClipboardListener();
        listener.start();}
}

应用程序将需要焦点从剪贴板获取事件。 [我不是Mac OS X开发人员，所以我不怎么解决这个问题，实际上我发布了一个 question about it ...]

It works, but the application will need focus to get the event from the clipboard. [I'm not Mac OS X developer so I don't how to fix this, actually I have posted a question about it...]
