Eclipse插件开发学习笔记【7】--- 添加首选项

首先，我们新建一个插件项目，打开plugin.xml文件选择扩展选项卡，添加一个org.eclipse.ui.preferencePages扩展点，并再添加一个page按照图中所示配置，注意第二个page的category为第一个page的id。

右键src文件夹，点击新建类，新建2个类分别为Page1，Page2，继承PreferencePage类，实现IWorkbenchPreferencePage接口。

/**

*

* Page1

*

*/

package addpreferencepage.pages;

import org.eclipse.jface.preference.PreferencePage;

import org.eclipse.swt.SWT;

import org.eclipse.swt.layout.FillLayout;

import org.eclipse.swt.widgets.Composite;

import org.eclipse.swt.widgets.Control;

import org.eclipse.swt.widgets.Label;

import org.eclipse.ui.IWorkbench;

import org.eclipse.ui.IWorkbenchPreferencePage;

public class Page1 extends PreferencePage implements IWorkbenchPreferencePage {

@Override

public void init(IWorkbench workbench) {  }

@Override

protected Control createContents(Composite parent) {

Composite topCom = new Composite(parent, SWT.NONE);

topCom.setLayout(new FillLayout());

new Label(topCom, SWT.NONE).setText("欢迎使用自定义首选项！");

return topCom;

}

}

/**

*

* Page2

*

*/

package addpreferencepage.pages;

import org.eclipse.jface.preference.PreferencePage;

import org.eclipse.swt.SWT;

import org.eclipse.swt.layout.FillLayout;

import org.eclipse.swt.widgets.Composite;

import org.eclipse.swt.widgets.Control;

import org.eclipse.swt.widgets.Label;

import org.eclipse.ui.IWorkbench;

import org.eclipse.ui.IWorkbenchPreferencePage;

public class Page2 extends PreferencePage implements IWorkbenchPreferencePage {

@Override

public void init(IWorkbench workbench) {  }

@Override

protected Control createContents(Composite parent) {

Composite topCom = new Composite(parent, SWT.NONE);

topCom.setLayout(new FillLayout());

new Label(topCom, SWT.NONE).setText("子选项！");

return topCom;

}

}

点击运行，效果如图：
