swing组件的选择与使用

[royya]

我想作一个简单的人机交互界面，运行时只有一个框，user输入一行，计算机答一行，做好了以后
大约就是下面的样子：
U：what is your name?
C:computer
U:what are you doning?
C:computing

我该选用swing组件中的哪一个呢？？
应该怎么实现那？
如果想让user和compuer的话用不同颜色显示又该怎么弄呢？

上面三个答哪个都给分！

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。

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。

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

[launch401]

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。

[zhangzhenyi]

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

[zhaohao19853]

能做这样的组件不要太多哦，你认为那种好就用哪种，哪种简单用哪种

[royya]

楼上的各位好厉害！！小妹谢过先！！
