如何使用Java Swing将一堆JPanels添加到我的JFrame中?

问题描述

我生成了一堆JPanels，然后将它们传递给扩展JFrame的类.如何向此JFrame中添加不确定数量的JPanel.我还在阅读有关JScrollPane的信息，是否应该以某种方式将其纳入设计中?

I generate a bunch of JPanels and then pass them into a class that extends JFrame. How do I add an indefinite number of JPanels to this JFrame. I was also reading about JScrollPane should I incorporate this somehow into the design?

示例代码:

class foo extends JPanel
{
  //generate JPanels
}

class bar extends JFrame
{
  //grab some amount of foo classes and put them into this JFrame and show it
}

在显示此JFrame时，我还需要注意什么吗?

Also is there anything I need to watch out for when showing this JFrame?

谢谢

推荐答案

CardLayout，JDesktopPane/JInternalFrame，JTabbedPane，JScrollPane-有很多选项.

CardLayout, JDesktopPane/JInternalFrame, JTabbedPane, JScrollPane - there are a number of options.

(耸耸肩)

• 在EDT上构建并显示GUI组件.
• pack() GUI，然后设置位置并调用setVisible(true).
• 不要依赖内容窗格的默认布局.
• 不要在顶级容器中实现自定义绘画.
• ..

• Construct and show GUI components on the EDT.
• pack() the GUI before setting the position and calling setVisible(true).
• Don't rely on the default layouts of content panes.
• Don't implement custom painting in a top level container.
• ..
