org.eclipse.ui.viewActions 使用心得

单飞 — Sun, 20 Apr 2008 02:24:00 GMT

因为TreeView要增加一个弹出菜单来
Java代码

1 private void createContextMenu(Composite parent) {
2         MenuManager mgr = new MenuManager();
3         mgr.setRemoveAllWhenShown(true);
4         final EntityTreeView tree = this;
5         mgr.addMenuListener(new IMenuListener() {
6             public void menuAboutToShow(IMenuManager manager) {
7                 // TODO Auto-generated method stub
8                 ISelection selection = tree.getSelection();
9                 if(selection instanceof IStructuredSelection){
10                     IStructuredSelection incoming = (IStructuredSelection)selection;
11                     if(incoming.size() >0 && incoming.getFirstElement() instanceof AbstractEntity){
12                         selectedEntity = (AbstractEntity)incoming.getFirstElement();
13                         fillContextMenu(manager,selectedEntity);
14                     }
15                 }
16
17             }
18
19         });
20
21         org.eclipse.swt.widgets.Menu menu = mgr.createContextMenu(this.getControl());
22         this.getControl().setMenu(menu);
23         getViewSite().registerContextMenu(mgr, this);
24     }
25
26     private void fillContextMenu(IMenuManager manager,AbstractEntity selectedEntity) {
27         org.eclipse.jface.action.IContributionItem items[] = getViewSite().getActionBars().getMenuManager().getItems();
28         for (IContributionItem item : items) {
29             if(item instanceof PluginActionContributionItem){
30                 PluginActionContributionItem pitem = (PluginActionContributionItem)item;
31                 if(selectedEntity instanceof CategoryModel){
32                     if ("com.test.actions.RefreshViewActionDelegate".equals(pitem.getAction().getId())){
33                         manager.add(item);
34                         continue;
35                     }
36                 }
37
38             }
39
40
41         }
42     }

plugin.xml

<extension
         point="org.eclipse.ui.viewActions">
      <viewContribution
            id="com.test.EntityContribution"
            targetID="com.test.View">
         <action
               class="com.etest.actions.AddActionDelegate"
               icon="icons/action.gif"
               id="com.etest.actions.AddActionDelegate"
               label="Add"
               menubarPath="category"
               style="push">
         action>

targetID指定那个View会获取到这些action
如果指定一个toolbarPath
就会在NavigatorBar显示这些action

重新定制StructuredTextEditor的PropertySheet

单飞 — Tue, 24 Apr 2007 07:17:00 GMT

重载getAdapter方法:
public Object getAdapter(Class required) {
        if (org.eclipse.ui.views.properties.IPropertySheetPage.class
                .equals(required){
          org.eclipse.wst.sse.ui.views.properties.PropertySheetConfiguration cfg = createPropertySheetConfiguration();
                if (cfg != null) {
                    PropertySheet propertySheetPage = new PropertySheet(
                            this);
                    propertySheetPage.setConfiguration(cfg);
                }

        }

public class PropertySheet extends Page implements
        IPropertySheetPage {
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
    //change form part
}

how to access eclipse Workspace

单飞 — Fri, 10 Nov 2006 11:31:00 GMT

IPath IFile IProject IWorkspace

String filePath = "\testP\src\context\test.html";
IPath path = new Path(filePath);
IWorkspaceRoot = root = ResourcesPlugin.getWorkspace().getRoot();

IProject ps[] = root.getProjects();
org.eclipse.core.resources.IFile file = root.getFileForLocation(path );
IProject = file.getProject();

root 是整个Workspace的根容器，它可以获取到子目录的文件。
和java.io.File不同的是IFile通常是get出来的，不是new出来的。
