    • Method Detail

      • handlePropertyChange

        protected void handlePropertyChange​(int propId)
        Handles a property change notification from a nested editor. The default implementation simply forwards the change to listeners on this multi editor by calling firePropertyChange with the same property id. For example, if the dirty state of a nested editor changes (property id ISaveablePart.PROP_DIRTY), this method handles it by firing a property change event for ISaveablePart.PROP_DIRTY to property listeners on this multi editor.

        Subclasses may extend or reimplement this method.

        propId - the id of the property that changed
      • doSave

        public void doSave​(IProgressMonitor monitor)
        Description copied from interface: ISaveablePart
        Saves the contents of this part.

        If the save is successful, the part should fire a property changed event reflecting the new dirty state (PROP_DIRTY property).

        If the save is cancelled through user action, or for any other reason, the part should invoke setCancelled on the IProgressMonitor to inform the caller.

        This method is long-running; progress and cancellation are provided by the given progress monitor.

        doSave in class EditorPart
        monitor - the progress monitor
      • doSaveAs

        public void doSaveAs()
        Description copied from interface: ISaveablePart
        Saves the contents of this part to another object.

        Implementors are expected to open a "Save As" dialog where the user will be able to select a new name for the contents. After the selection is made, the contents should be saved to that new name. During this operation a IProgressMonitor should be used to indicate progress.

        If the save is successful, the part fires a property changed event reflecting the new dirty state (PROP_DIRTY property).

      • init

        public void init​(IEditorSite site,
                         IEditorInput input)
                  throws PartInitException
        Description copied from interface: IEditorPart
        Initializes this editor with the given editor site and input.

        This method is automatically called shortly after the part is instantiated. It marks the start of the part's lifecycle. The IWorkbenchPart.dispose method will be called automically at the end of the lifecycle. Clients must not call this method.

        Implementors of this method must examine the editor input object type to determine if it is understood. If not, the implementor must throw a PartInitException

        Specified by:
        init in interface IEditorPart
        Specified by:
        init in class EditorPart
        site - the editor site
        input - the editor input
        PartInitException - if this editor was not initialized successfully
      • isDirty

        public boolean isDirty()
        Description copied from interface: ISaveablePart
        Returns whether the contents of this part have changed since the last save operation. If this value changes the part must fire a property listener event with PROP_DIRTY.

        Note: this method is called often on a part open or part activation switch, for example by actions to determine their enabled status.

        Specified by:
        isDirty in interface ISaveablePart
        Specified by:
        isDirty in class EditorPart
        true if the contents have been modified and need saving, and false if they have not changed since the last save
      • isSaveAsAllowed

        public boolean isSaveAsAllowed()
        Description copied from interface: ISaveablePart
        Returns whether the "Save As" operation is supported by this part.
        Specified by:
        isSaveAsAllowed in interface ISaveablePart
        Specified by:
        isSaveAsAllowed in class EditorPart
        true if "Save As" is supported, and false if not supported
      • setFocus

        public void setFocus()
        Description copied from interface: IWorkbenchPart
        Asks this part to take focus within the workbench. Parts must assign focus to one of the controls contained in the part's parent composite.

        Clients should not call this method (the workbench calls this method at appropriate times). To have the workbench activate a part, use IWorkbenchPage.activate(IWorkbenchPart) instead.

      • getActiveEditor

        public final IEditorPart getActiveEditor()
        Returns the active inner editor.

      • getInnerEditors

        public final IEditorPart[] getInnerEditors()
        Returns an array with all inner editors.

      • setChildren

        public final void setChildren​(IEditorPart[] children)
        Set the inner editors. Should not be called by clients.
        children - the inner editors of this multi editor
        This method is not intended to be referenced by clients.
      • innerEditorsCreated

        protected abstract void innerEditorsCreated()
        Called as soon as the inner editors have been created and are available.
      • activateEditor

        public void activateEditor​(IEditorPart part)
        Activates the given nested editor.

      • getInnerEditorContainer

        public abstract Composite getInnerEditorContainer​(IEditorReference innerEditorReference)
        This method is called after createPartControl has been executed and should return the container for the given inner editor.
        innerEditorReference - a reference to the inner editor that is being created.
        the container in which the inner editor's pane and part controls are to be created.
