swing分割窗口控件JSplitPane使用方法详解

package swing; import java.awt.event.ComponentAdapter; import java.awt.event.ComponentEvent; import javax.swing.JFrame; import javax.swing.JSplitPane; import javax.swing.JPanel; public class MainFrame extends JFrame {    JSplitPane jSplitPane1 = new JSplitPane();  JPanel jPanel1 = new JPanel();  JPanel jPanel2 = new JPanel();  private static final long serialVersionUID = 1L;  public static void main(String[] args){   new MainFrame();   }  public void myinit(){   this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//设定窗体关闭后自动退出进程   this.setSize(800,600);//设定窗体的默认尺寸   this.setExtendedState(JFrame.MAXIMIZED_BOTH);//设定窗体状态为屏幕最大化，即全屏尺寸。   this.setVisible(true);//显示窗体   this.jSplitPane1.setDividerLocation(0.7);//设定分割面板的左右比例(这时候就生效了，如果放在setVisible(true)这据之前就不会有效果。)   this.addComponentListener(new ComponentAdapter() {    public void componentResized(ComponentEvent e) {     jSplitPane1.setDividerLocation(0.7);    }   });  }   public MainFrame() {   try {    jbInit();    myinit();   } catch (Exception ex) {    ex.printStackTrace();   }  }  private void jbInit() throws Exception {   this.getContentPane().add(jSplitPane1, java.awt.BorderLayout.CENTER);   jSplitPane1.add(jPanel1, JSplitPane.LEFT);   jSplitPane1.add(jPanel2, JSplitPane.RIGHT);   jSplitPane1.setEnabled(false);   jSplitPane1.setOneTouchExpandable(true);  } }
