java在线聊天项目 swt可视化窗口Design 重新设计聊天窗口

Posted 2020-10-17 Advancing Swift

设计的聊天窗口如下：

制作过程：

首先，在默认的BorderLayout视图下，

上边也就是North处添加一个JPanel，将Layout调整为BorderLayout，West放一个JLabel用来放照片，

Center再放一个JPanel，布局调整为BorderLayout，Center和South各方一个JLabel，分别放用户昵称和名言。

下边模仿QQ是一个上下可以自行拆分大小的JSplitPane，调整为垂直的上下模式。

拆分框的下边放一个JPanel，设布局为BorderLayout，

再在上中下分别放JPanel，JScrollPane，JPanel，

上边放一个按钮调整为左对齐，下边放两个按钮调整为右对齐，中间放一个JTextArea

最后，拆分框上边放一个JScrollPane，里边放一个JTextArea。
