Eclipse插件开发工程属性页

介绍

本文介绍如何自定义一个Eclipse中的工程属性页面。

扩展点 org.eclipse.ui.propertyPages

[codesyntax lang="xml"]

<extension point="org.eclipse.ui.propertyPages">
 <page objectClass="org.eclipse.core.resources.IResource"
  adaptable="true" name="%osgi.imported_packages"
  class="org.suren.osgi.ui.properties.ImportPackagePage"
  id="org.suren.osgi.ui.properties.ImportPackagePage">
 </page>
</extension>

[/codesyntax] 实现类很简单，就是使用SWT创建一个页面就好。重点是要获取当前选择的工程，然后显示该工程的信息。下面是例子： [codesyntax lang="java"]

/**

package org.suren.osgi.ui.properties;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Set;
import java.util.TreeSet;

import org.eclipse.core.runtime.IAdaptable;
import org.eclipse.jdt.core.IJavaProject;
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.Text;
import org.eclipse.ui.dialogs.PropertyPage;
import org.suren.osgi.util.JavaProjectUtil;

/**

public class ImportPackagePage extends PropertyPage {

 @Override
 protected Control createContents(Composite parent) {
  IAdaptable ele = getElement();
  
  IJavaProject javaProject = JavaProjectUtil.getJavaProject(ele);
  
  List<String> importPackages = new ArrayList<String>();
  JavaProjectUtil.findImportPackage(javaProject, importPackages);
  
  Composite contents = new Composite(parent, SWT.NULL);
  contents.setLayout(new FillLayout());
  
  Set<String> packagesSet = new TreeSet<String>();
  for(String pkg : importPackages)
  {
   pkg = pkg.substring(0, pkg.lastIndexOf("."));
   packagesSet.add(pkg);
  }

  StringBuffer buf = new StringBuffer();
  Iterator<String> it = packagesSet.iterator();
  while(it.hasNext())
  {
   String pkg = it.next();
   buf.append("\n").append(pkg);
  }
  if(buf.length() > 0)
  {
   buf.delete(0, 2);
  }
  
  new Text(contents, SWT.MULTI).setText(buf.toString());;
  
  contents.layout(true, true);
  
  return contents;
 }
}

[/codesyntax]
