《Java程序设计》第17周课程设计：《猜猜看》游戏 第四天

今天我为了实现按钮判断进行了少量的调整，利用输出的text进行判断是否其图片与标记的名字相对应；

可惜我还不能在上方对话框显示名字；

图片旁边的三个黑点其实获取的图片的名称，因为避免被看见我把他隐藏了；

try {icon = new ImageIcon(ImageIO.read(new File(strTmp)));} catch (IOException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}                       Image image = icon.getImage(); // 从图表中获取到图片                       Image smallImage = image.getScaledInstance(170,200,Image.SCALE_FAST);// 缩放图像  icon = new ImageIcon(smallImage);//把Image文件转化为ImageIcon                    lblImg1.setIcon(icon);   lblImg1.setText(strTmp);  

lblImg1.setText(strTmp);

插入这句话获取那图片的文件名并显示，但我隐藏了；

接下来我要完善在图片上标出要猜的图片主人的信息，希望明天可以好好努力达成目标。
