问题描述

我为欢迎屏幕设计了一个界面，其中一个 JFrame 包含两个 JPanel(右侧的 JPanel1 和左侧的 JPanel2).左边的按钮是切换JPanel1中的Panels.我想按下一个按钮来用另一个 JPanel 替换 JPanel1 的内容，但我不知道怎么做.请帮忙.

I designed an interface for the welcome screen with one JFrame included two JPanels (JPanel1 on right and JPanel2 on left). The buttons on the left is to switch the Panels in JPanel1. I want to press on a button to replace JPanel1 content with another JPanel but I don`t know how. Please help.

推荐答案

我发现最好的答案是我将只创建一个 JFrame 并让一个大的 JPanel 包含两个 JPanel(JPanelLeft 包含按钮，JPanelRight 包含按钮的内容做)然后我将为每个 JButton 复制主 JPanel.当我按下任何按钮时，我将执行 (JFrame.getContentPane.removeAll) 以删除旧的 JPanel，然后 (JFrame.getContentPane.Add(NewJPanel).

The best answer I found is that I will create one JFrame only and gonna make one big JPanel include two JPanels (JPanelLeft include the buttons and JPanelRight include what the button do) then I will copy the main JPanel for each JButton. When I press on any button I will do (JFrame.getContentPane.removeAll) to remove the old JPanel then (JFrame.getContentPane.Add(NewJPanel).

这对我有用，并保持我想要的设计.感谢每一个人.

This works for me and keep my design as I Want. Thanks for every body.
