我需要在Java中使用以下布局：
但是,我应该发现没有布局管理器可以简单地为我处理这个问题.我需要在JFrame中使用此布局.
有没有中途简单的方法我能做到这一点？
提前致谢！
编辑：谢谢你们所有人,我终于成功了！
这就是我所做的(正如你所提议的那样)
>窗口的BorderLayout
> leftPanel,GridLayout(1,1)/ * to stretch * /,在窗口中添加Component 1,WEST
> rightPanel,BorderLayout,CENTER在窗口中
> rightTop(添加到rightPanel作为CENTER)面板,添加组件2
> rightBottom(添加到rightPanel作为SOUTH)面板,GridLayout(1,1)(也用于拉伸),添加组件3
谢谢大家,我的建议我混合了^^
解决方法:
我知道你通过放置在BorderLayout布局管理器中的混合JPanel解决了你的问题.如果有效,那没关系.
对于那些对使用GridBagLayout作为解决方案感到好奇的人,我将此类作为示例.只需复制粘贴,编译和运行即可.拖动这个小应用程序窗口的角落,看看调整窗口大小的效果.
// Example code showing the flexibility of GridBagLayout.
// Source code generated by WindowBuilder 1.0.0r37 in Eclipse (Indigo Release) on Mac OS X 10.6.7.
// ? 2011 Basil Bourque. http://www.GridsGoneWild.com/
// This source code may be used freely forever by anyone taking full responsibility for doing so.
// Each layout manager bundled in Java is quite different from the others. They all have strengths and weaknesses,
// each designed for different purposes and effects.
// GridBagLayout is the most powerful and flexible, but takes some patient practice to understand.
// Funny animated video commentary by a GridBagLayout programmer: http://madbean.com/anim/totallygridbag/
// Hand-coding GridBagLayout is certainly tedious, and nearly impossible for complex forms. So I recommend the use of
// a visual GUI builder such as WindowBuilder in Eclipse, JFormDesigner from FormDev.com, or Matisse in NetBeans.
// Key ideas, "grow" & "fill":
// ? In WindowBuilder's Design View, select a widget, then use the "Horizontal grow" and "Vertical grow" icons found in the upper right tool bar.
// ? Use the widget's (label's, button's) "Constraints" > "fill" property in the property sheet of WindowBuilder.
// Further ideas:
// ? To contain multiple widgets in each area, use JPanel objects where I have used single JLabel and JButton objects.
// Nesting JPanels inside JPanels (or in the JFrame's contentPane) is considered normal in Swing. Each JPanel has its own layout manager.
// ? If need be, you can set the Minimum, Maximum, and/or Preferred size of a widget or JPanel.
// ? If you want certain widgets or JPanels to get disproportionately more or less of the space gained or lost when a window is resized,
// use "weightx" and "weighty" properties.
// WindowBuilder Tips:
// ? If it's your first time: Open the .java file, then click the "Design" button at bottom to see visual editor.
// ? Click the "Show Advanced properties" icon at top of a widget's property sheet to see many hidden properties.
// package com.your.package.goes.here; // Uncomment this line, and modify to suit your own package.
