找到图片组件，添加监听鼠标事件

JComponent component = headItem.getComponent();MouseAdapter paramMouseListener = new MouseAdapter() {
   @Overridepublic void mouseClicked(MouseEvent event) {
   	if(event.getButton() == MouseEvent.BUTTON1 && event.getClickCount() == 1){
   			PsndocFormEditor ed = (PsndocFormEditor) getEditor();    		BillItem headItem = ed.getBillCardPanel().getHeadItem("photo");    		String imagePath = headItem.getImagePath();    		if(imagePath ==null){
       			return;    		}    		ImagDialog imagDialog = new ImagDialog(getEntranceUI(),imagePath);			imagDialog.showModal();			imagDialog.destroy();		}	} 			};component.addMouseListener(paramMouseListener);
