通过Win API 模拟鼠标点击,使C# Java交互 (PART.2 Java部分)

Java部分:
   调用:
  

ArrayList<QueueItem> li = new ArrayList<QueueItem>();
        li.add(new QueueItem("WindowsForms10.Window.8.app3","采集系统"));
        li.add(new QueueItem("WindowsForms10.BUTTON.app3","选项"));
        int result = NativeWin32.ClickOnWindow(li);
        System.out.print(result);

PINVOKE封装采用 NativeCall [ http://johannburkard.de/software/nativecall/ ]

QueueItem,窗体查找时的节点定义.

public class QueueItem
{
    public String ClassName;
    public String WindowCaption;
    public boolean IsParent=true;
    public QueueItem(String className,String windowCaption)
    {
        ClassName=className;
        WindowCaption=windowCaption;
    }
    public QueueItem(String className,String windowCaption,boolean isParent)
    {
        ClassName=className;
        WindowCaption=windowCaption;
        IsParent=isParent;
    }
}
