向导页面调整大小

Question

我正在开发一个具有多页面向导的应用程序。我们希望它像Eclipse中的Preferences页面一样执行。拖动左侧时，只会调整右侧的大小。 下面显示了向导的BasePage。此向导中的每个页面都扩展此BasePage。如何修改BasePage？

import org.eclipse.jface.wizard.WizardPage;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.SashForm;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class BasePage extends WizardPage 
{   
    private Logger log = LoggerFactory.getLogger(getClass());

    //Color blue = SWTResourceManager.getColor(65, 105, 225);
    //Color black = SWTResourceManager.getColor(0, 0, 0);
    //Button rbtnIntroduce; 
    Button rbtnSourcedb;
    Button rbtnTargetdb;
    Button rbtnDatatype;
    Button rbtnSelectObjects;
    Button rbtnMigrate;
    Composite compositeContent;
    SashForm sashContainer;

    public BasePage(String name) 
    {
        super(name);
    }

    @Override
    public void createControl(Composite parent) 
    {
        log.debug("BasePage.createControl");

        sashContainer = new SashForm(parent, SWT.NONE);
        setControl(sashContainer);// must set control for wizard page

        GridLayout layout = new GridLayout();
        layout.numColumns = 2;
        sashContainer.setLayout(layout);        

        Composite compositeNavigator = new Composite(sashContainer, SWT.BORDER);

        /*
        rbtnIntroduce = new Button(compositeNavigator, SWT.RADIO);
        //rbtnIntroduce.setForeground(blue);
        rbtnIntroduce.setBounds(10, 10, 110, 20);
        rbtnIntroduce.setText("Introduce");
        */

        rbtnTargetdb = new Button(compositeNavigator, SWT.RADIO);
        rbtnTargetdb.setBounds(10, 35, 110, 20);
        rbtnTargetdb.setText("Target DB");

        rbtnSourcedb = new Button(compositeNavigator, SWT.RADIO);
        rbtnSourcedb.setBounds(10, 60, 110, 20);
        rbtnSourcedb.setText("Source DB");

        rbtnDatatype = new Button(compositeNavigator, SWT.RADIO);
        rbtnDatatype.setBounds(10, 110, 110, 20);
        rbtnDatatype.setText("Datatype Cast");

        rbtnSelectObjects = new Button(compositeNavigator, SWT.RADIO);
        rbtnSelectObjects.setBounds(10, 85, 110, 20);
        rbtnSelectObjects.setText("Object Choose");

        rbtnMigrate = new Button(compositeNavigator, SWT.RADIO);
        rbtnMigrate.setBounds(10, 135, 110, 20);
        rbtnMigrate.setText("Migrate"); 

        compositeContent = new Composite(sashContainer, SWT.NONE);      
        sashContainer.setWeights(new int[] { 1, 3 });
    }

    /*
    private Button getRadioButton(Composite compositeNavigator, String name)
    {
        Button rbtn = new Button(compositeNavigator, SWT.RADIO);
        rbtn.setText(name);
        return rbtn;
    }
    */

    void updatePage(Button btn)
    {
        /*
        rbtnIntroduce.setSelection(rbtnIntroduce==btn);
        rbtnIntroduce.setEnabled(rbtnIntroduce==btn);
        //rbtnIntroduce.setForeground(rbtnIntroduce==btn? blue:black);
        */

        rbtnTargetdb.setSelection(rbtnTargetdb==btn);
        rbtnTargetdb.setEnabled(rbtnTargetdb==btn);
        //rbtnTargetdb.setForeground(rbtnTargetdb==btn? blue:black);

        rbtnSourcedb.setSelection(rbtnSourcedb==btn);
        rbtnSourcedb.setEnabled(rbtnSourcedb==btn);
        //rbtnSourcedb.setForeground(rbtnSourcedb==btn? blue:black);

        rbtnTargetdb.setSelection(rbtnTargetdb==btn);
        rbtnTargetdb.setEnabled(rbtnTargetdb==btn);
        //rbtnTargetdb.setForeground(rbtnTargetdb==btn? blue:black);

        rbtnSelectObjects.setSelection(rbtnSelectObjects==btn);
        rbtnSelectObjects.setEnabled(rbtnSelectObjects==btn);

        rbtnMigrate.setEnabled(rbtnMigrate==btn);
        //rbtnMigrate.setForeground(rbtnMigrate==btn? blue:black);      
    }

}
