现在很多开发工具都采用MVC的开发模式，WPF是比较具有代表性的，AWT也具有一定的MVC特征，相对来说肯定WPF更具有灵活性，现在来类比两者中的布局管理器
1:JAVA-BorderLayout与WPF-DockPanel
特点:可以将组建停靠在四边，WPF中没有Center，想有Java的CENTER效果，要设置LastChildFill为True

//Java BorderLayout private JPanel borderPanel=new JPanel(new BorderLayout()); borderPanel.add(new JButton("North"),BorderLayout.NORTH); borderPanel.add(new JButton("South"),BorderLayout.SOUTH); borderPanel.add(new JButton("Center"),BorderLayout.CENTER); borderPanel.add(new JButton("West"),BorderLayout.WEST); borderPanel.add(new JButton("East"),BorderLayout.EAST); |

<!--WPF XAML DockPanel--> <DockPanel Margin="5" LastChildFill="True"> <Button DockPanel.Dock="Top">Top</Button> <Button DockPanel.Dock="Bottom">Button</Button> <Button DockPanel.Dock="Left">Left</Button> <Button DockPanel.Dock="Right">Right</Button> <Button></Button> </DockPanel> |
设置边距:Java-setHgap,setVgap--WPF-Margin
绝对位置:Java-东南西北--WPF-左右上下
2:Java-GridLayout与WPF-UniformGrid
特点:先确定行列，然后将组建按添加顺序依次排放

//Java GridLayout private JPanel gridPanel=new JPanel(new GridLayout(2,2)); gridPanel.add(new JButton("0")); gridPanel.add(new JButton("1")); gridPanel.add(new JButton("2")); |

3:Java:FlowLayout与WPF:WarpLayout
特点：按顺序排列下去，如果剩余长度不足，则自动换行

//Java FlowLayout private JPanel flowPanel=new JPanel(new FlowLayout()); flowPanel.add(new JButton("One")); flowPanel.add(new JButton("Two")); flowPanel.add(new JButton("Three")); flowPanel.add(new JButton("Four")); flowPanel.add(new JButton("Five")); flowPanel.add(new JButton("Six")); |

4：最重要
Java:GridBagLayout与WPF:Grid
特点:面板以单元格布局，组建可以定位到置顶单元格

private JPanel gridBagPanel=new JPanel(new GridBagLayout()); GridBagConstraints c=new GridBagConstraints(); c.fill=GridBagConstraints.BOTH; c.weightx=1.0; c.weighty=1.0; c.gridwidth=GridBagConstraints.REMAINDER; gridBagPanel.add(new JButton("One"),c); c.gridx=1; c.gridy=1; gridBagPanel.add(new JButton("TWO"),c); c.gridx=1; c.gridy=2; gridBagPanel.add(new JButton("Three"),c); c.gridx=0; c.gridy=1; c.gridheight=2; c.gridwidth=1; gridBagPanel.add(new JButton("Four"),c); |

总体上感觉，AWT的布局管理和WPF的布局管理原理上相似，当不如WPF那么灵活
