    • Field Detail

      • EDITOR_KEY

        public static final QualifiedName EDITOR_KEY
        The persistent property key used on IFile resources to contain the preferred editor ID to use.

        Example of retrieving the persisted editor id:

         
          IFile file = ...
          IEditorDescriptor editorDesc = null;
          try {
                String editorID = file.getPersistentProperty(EDITOR_KEY);
                if (editorID != null) {
                        editorDesc = editorReg.findEditor(editorID);
                }
          } catch (CoreException e) {
                // handle problem accessing persistent property here
          }
         
         

        Example of persisting the editor id:

         
          IFile file = ...
          try {
                file.setPersistentProperty(EDITOR_KEY, editorDesc.getId());
          } catch (CoreException e) {
                // handle problem setting persistent property here
          }
         
         
      • EDITOR_ID_ATTR

        public static final String EDITOR_ID_ATTR

      • getMarkerHelpRegistry

        public static IMarkerHelpRegistry getMarkerHelpRegistry()
        Returns the marker help registry for the workbench.
        Returns:

      • gotoMarker

        public static void gotoMarker​(IEditorPart editor,
                                      IMarker marker)
        Sets the cursor and selection state for the given editor to reveal the position of the given marker. This is done on a best effort basis. If the editor does not provide an IGotoMarker interface (either directly or via IAdaptable.getAdapter), this has no effect.
        Parameters:
        editor - the editor
        marker - the marker
      • openEditor

        public static IEditorPart openEditor​(IWorkbenchPage page,

                                      throws PartInitException
        Opens an editor on the given object.

        If the page already has an editor open on the target object then that editor is brought to front; otherwise, a new editor is opened.

        Parameters:
        page - the page in which the editor will be opened
        input - the editor input
        editorId - the id of the editor extension to use
        Returns:
        an open editor or null if an external editor was opened
        Throws:
        PartInitException - if the editor could not be initialized

                                      throws PartInitException
        Opens an editor on the given IFileStore object.

        Unlike the other openEditor methods, this one can be used to open files that reside outside the workspace resource set.

        If the page already has an editor open on the target object then that editor is brought to front; otherwise, a new editor is opened.

        Parameters:
        page - the page in which the editor will be opened
        uri - the URI of the file store representing the file to open
        editorId - the id of the editor extension to use
        activate - if true the editor will be activated opened
        Returns:
        an open editor or null if an external editor was opened
        Throws:
        PartInitException - if the editor could not be initialized

                                      throws PartInitException
        Opens an editor on the file resource of the given marker.

        If this page already has an editor open on the marker resource file that editor is brought to front; otherwise, a new editor is opened.The cursor and selection state of the editor are then updated from information recorded in the marker.

        If the marker contains an EDITOR_ID_ATTR attribute the attribute value will be used to determine the editor type to be opened. If not, the registered editor for the marker resource file will be used.

        Parameters:
        page - the workbench page to open the editor in
        marker - the marker to open
        Returns:
        an open editor or null not possible

        public static IEditorDescriptor getDefaultEditor​(IFile file)
        Returns the default editor for a given file. This method will attempt to resolve the editor based on content-type bindings as well as traditional name/extension bindings.

        A default editor id may be registered for a specific file using setDefaultEditor. If the given file has a registered default editor id the default editor will derived from it. If not, the default editor is determined by taking the file name for the file and obtaining the default editor for that name.
