swing组件的选择与使用

Question

用JOptionPane
JOptionPane.showInputDialog()//提问用
JOptionPane.showMessageDialog()//回答用

Answer 1

用JTextField就可以实现吧，输入一行后触发时间，在事件处理方法中，调用回答算法，把结果JTextField.setText()到textfield上。

Answer 2

要颜色不同，可以设置么。jb里面应该有选项（很久不用了记不住怎么写了）api应该在基类里找

Answer 3

颜色不是很好实现，这里没有实现。给我一个e-mail,有空把颜色的实现写完给你。

Answer 4

搂住是要做qq那种还是谈对话框的那种呢？用JOptionPane
JOptionPane.showInputDialog()//提问用
JOptionPane.showMessageDialog()//回答用  这个答案是做对话框的。
如果是要做qq那种，只需要JButton JTextArea就行了。
