Class TemplatesView

  • All Implemented Interfaces:
    IAdaptable, IExecutableExtension, IPartListener, IPersistable, IViewPart, IWorkbenchPart, IWorkbenchPart2, IWorkbenchPart3, IWorkbenchPartOrientation

    public final class TemplatesView
    extends PageBookView
    The Templates view.hosts ITemplatesPages that shows the templates for the currently active editor part.

    When this view notices an editor being activated, it uses the Eclipse adapter mechanism to get its ITemplatesPage. Hence, editors that want to provide a templates page need to provide such an adapter:

     Object getAdapter() {
            ...
            if (ITemplatesPage.class.equals(required)) {
                    if (fTemplatesPage == null)
                            fTemplatesPage= new JavaTemplatesPage(this);
                            return fTemplatesPage;
                    }
            }
            ...
     }
     

    Note: This plug-in does not contribute this view. Clients that want to use this view must check whether it is available and if not, contribute this view via extension point using the specified view Id ID:

     <extension
           point="org.eclipse.ui.views">
        <view
              name="%templatesViewName"
              icon="$nl$/icons/full/eview16/templates.png"
              category="org.eclipse.ui"
              class="org.eclipse.ui.texteditor.templates.TemplatesView"
              id="org.eclipse.ui.texteditor.TemplatesView">
        </view>
     </extension>
     
    The templates.png icon can be copied from this plug-in.

    If the editor supports a templates page, the editor instantiates and configures the page, and returns it. This page is then added to this Templates view and immediately made the current page (the Templates view needs not to be visible). If the editor does not support a templates page, the Templates view shows a special default page which makes it clear to the user that no templates are available. When the Templates view notices a different editor being activated, it flips to the editor's corresponding templates page. When the templates view notices an editor being closed, it may destroy the editor's corresponding templates page.

    This class is not intended to be instantiated or subclassed by clients.

      • createDefaultPage

        protected IPage createDefaultPage​(PageBook book)
        Description copied from class: PageBookView
        Creates and returns the default page for this view.

        Subclasses must implement this method.

        Subclasses must call initPage with the new page (if it is an IPageBookViewPage) before calling createControl on the page.

        Specified by:
        createDefaultPage in class PageBookView
        Parameters:
        book - the pagebook control
        Returns:
        the default page
      • createPartControl

        public void createPartControl​(Composite parent)
        Description copied from class: PageBookView
        The PageBookView implementation of this IWorkbenchPart method creates a PageBook control with its default page showing. Subclasses may extend.
        Specified by:
        createPartControl in interface IWorkbenchPart
        Overrides:
        createPartControl in class PageBookView
        Parameters:
        parent - the parent control
      • getBootstrapPart

        protected IWorkbenchPart getBootstrapPart()
        Description copied from class: PageBookView
        Returns the active, important workbench part for this view.

        When the page book view is created it has no idea which part within the workbook should be used to generate the first page. Therefore, it delegates the choice to subclasses of PageBookView.

        Implementors of this method should return an active, important part in the workbench or null if none found.

        Subclasses must implement this method.

        Specified by:
        getBootstrapPart in class PageBookView
        Returns:
        the active important part, or null if none
      • isImportant

        protected boolean isImportant​(IWorkbenchPart part)
        Description copied from class: PageBookView
        Returns whether the given part should be added to this view.

        Subclasses must implement this method.

        Specified by:
        isImportant in class PageBookView
        Parameters:
        part - the input part
        Returns:
        true if the part is relevant, and false otherwise
      • getTemplateStore

        public TemplateStore getTemplateStore()

        public TemplatePersistenceData[] getSelectedTemplates()
        Returns the currently selected templates.
        Returns:
        array of selected templates, or null if the current page does not provide that information
