Interface IWorkbenchPage

All Superinterfaces:
IPartService, ISelectionService
All Known Implementing Classes:
WorkbenchPage
public interface IWorkbenchPage extends IPartService, ISelectionService
A workbench page consists of an arrangement of views and editors intended to be presented together to the user in a single workbench window.

A page can contain 0 or more views and 0 or more editors. These views and editors are contained wholly within the page and are not shared with other pages. The layout and visible action set for the page is defined by a perspective.

The number of views and editors within a page is restricted to simplify part management for the user. In particular:

  • Unless a view explicitly allows for multiple instances in its plug-in declaration there will be only one instance in a given workbench page.
  • Only one editor can exist for each editor input within a page.

This interface is not intended to be implemented by clients.

    • openEditor

      IEditorPart openEditor(IEditorInput input, String editorId) throws PartInitException
      Opens an editor on the given input.

      If this page already has an editor open on the target input that editor is activated; otherwise, a new editor is opened. Two editor inputs, input1 and input2, are considered the same if 

       input1.equals(input2) == true

      The editor type is determined by mapping editorId to an editor extension registered with the workbench. An editor id is passed rather than an editor object to prevent the accidental creation of more than one editor for the same input.

      Note that as of 3.2, this method also saves views that implement ISaveablePart and are dirty.

      Parameters:
      confirm - true to ask the user before saving unsaved changes (recommended), and false to save unsaved changes without asking
      Returns:
      true if the command succeeded, and false if the operation was canceled by the user or an error occurred while saving

      Parameters:
      editor - the editor to close
      confirm - true to ask the user before saving unsaved changes (recommended), and false to save unsaved changes without asking
      Returns:
      true if the command succeeded, and false if the editor was not saved

    • setEditorAreaVisible

      void setEditorAreaVisible(boolean showEditorArea)
      Show or hide the editor area for the page's active perspective.
      Parameters:
      showEditorArea - true to show the editor area, false to hide the editor area

    • setPerspective

      void setPerspective(IPerspectiveDescriptor perspective)
      Changes the visible views, their layout, and the visible action sets within the page to match the given perspective descriptor. This is a rearrangement of components and not a replacement. The contents of the old perspective descriptor are unaffected.

      When a perspective change occurs the old perspective is deactivated (hidden) and cached for future reference. Then the new perspective is activated (shown). The views within the page are shared by all existing perspectives to make it easy for the user to switch between one perspective and another quickly without loss of context.

      During activation the action sets are modified. If an action set is specified in the new perspective which is not visible in the old one it will be created. If an old action set is not specified in the new perspective it will be disposed.

      The visible views and their layout within the page also change. If a view is specified in the new perspective which is not visible in the old one a new instance of the view will be created. If an old view is not specified in the new perspective it will be hidden. This view may reappear if the user selects it from the View menu or if they switch to a perspective (which may be the old one) where the view is visible.

      The open editors are not modified by this method.

      Parameters:
      perspective - the perspective descriptor

    • showActionSet

      void showActionSet(String actionSetID)
      Shows an action set in this page.

      In most cases where this method is used the caller is tightly coupled to a particular action set. They define it in the registry and may make it visible in certain scenarios by calling showActionSet. A static variable is often used to identify the action set id in caller code.

    • showView

      IViewPart showView(String viewId) throws PartInitException
      Shows the view identified by the given view id in this page and gives it focus. If there is a view identified by the given view id (and with no secondary id) already open in this page, it is given focus.
      Parameters:
      viewId - the id of the view extension to use
      Returns:
      the shown view
      Throws:
      PartInitException - if the view could not be initialized

    • showView

      IViewPart showView(String viewId, String secondaryId, int mode) throws PartInitException
      Shows a view in this page with the given id and secondary id. The behaviour of this method varies based on the supplied mode. If VIEW_ACTIVATE is supplied, the view is given focus. If VIEW_VISIBLE is supplied, then it is made visible but not given focus. Finally, if VIEW_CREATE is supplied the view is created and will only be made visible if it is not created in a folder that already contains visible views.

      This allows multiple instances of a particular view to be created. They are disambiguated using the secondary id. If a secondary id is given, the view must allow multiple instances by having specified allowMultiple="true" in its extension.

      Parameters:
      viewId - the id of the view extension to use
      secondaryId - the secondary id to use, or null for no secondary id
      mode - the activation mode. Must be VIEW_ACTIVATE, VIEW_VISIBLE or VIEW_CREATE

    • setWorkingSets

      void setWorkingSets(IWorkingSet[] sets)
      Set the working sets for this page. Any duplicate entries will be removed from the array by this method.

    • getAggregateWorkingSet

      IWorkingSet getAggregateWorkingSet()
      Return a working set that contains all of the elements contained in the array of working sets provided by getWorkingSets(). Should this array or the underlying elements in any of the working sets change this set will be updated.

      This working set is never null, even if there are no working sets assigned to this page via setWorkingSets(IWorkingSet[]). It is recommended that any client that uses this API be aware of this and act accordingly. Specifically, it is recommended that any client utilizing this or any other IWorkingSet whose IWorkingSet.isAggregateWorkingSet() returns true act as if they are not using any working set if the set is empty. These clients should also maintain an awareness of the contents of aggregate working sets and toggle this behavior should the contents of the aggregate either become empty or non-empty.

      Example pseudocode showing how some workingset utilizing component could react to changes in aggregate working sets: 

       
 private IWorkingSet myWorkingSet;

 IPropertyChangeListener workingSetListener = new IPropertyChangeListener() {
        void propertyChange(PropertyChangeEvent event) {
                if (isMyCurrentWorkingSet(event)) {
                        if (isEmptyAggregate(myWorkingSet)) {
                                showNoSet();
                        }
                        else {
                                showSet();
                        }
                }
        }
 };

 void setWorkingSet(IWorkingSet newSet) {
                myWorkingSet = newSet;
                if (myWorkingSet == null || isEmptyAggregate(myWorkingSet)){
                        showNoSet();
                }
                else {
                        showSet();
                }

    • hideEditor

      void hideEditor(IEditorReference ref)
      Remove an open editor, turn it into a non-participating editor.

      A non-participating editor will not be returned in the list of open editors (getEditorReferences()) and will not be visible in the editor area. However, it will continue to participate in the save lifecycle and may still be closed by some workbench close events.

      Behaviour for hiding and showing editors from multiple stacks is not defined (and unsupported) at this time.

      Parameters:

    • openEditors

      IEditorReference[] openEditors(IEditorInput[] inputs, String[] editorIDs, int matchFlags) throws MultiPartInitException
      Opens editors for the given inputs. Only the editor constructed for the first input gets activated.

      The editor type is determined by mapping editorIDs to an editor extension registered with the workbench. An editor id is passed rather than an editor object to prevent the accidental creation of more than one editor for the same input. It also guarantees a consistent lifecycle for editors, regardless of whether they are created by the user or restored from saved data.

      The length of the input array and editor ID arrays must be the same. The editors are opened using pairs of { input[i], editorIDs[i] }.

      Parameters:
      inputs - the editor inputs
      editorIDs - the IDs of the editor extensions to use, in the order of inputs
      matchFlags - a bit mask consisting of zero or more of the MATCH_* constants OR-ed together
      Returns:
      references to the editors constructed for the inputs. The editors corresponding to those reference might not be materialized.
      Throws:
      MultiPartInitException - if at least one editor could not be created or initialized

    • openEditors

      IEditorReference[] openEditors(IEditorInput[] inputs, String[] editorIDs, IMemento[] mementos, int matchFlags, int activateIndex) throws MultiPartInitException
      Opens editors for the given inputs. Only the editor constructed for the given index will be activated.

      There are effectively two different ways to use this method based on what information the supplied mementos contain @see org.eclipse.ui.IWorkbenchPage #getEditorState(org.eclipse.ui.IEditorReference []):

      1. If the mementos contain the 'input' information then only the memento itself is required since it can be used to re-create the editor input and its editorID. If all the mementos are of this type then the inputs and editorIDs arrays may be null.
      2. If the supplied memento only contains the editor state then both the input and editorID must be non-null.

      The editor type is determined by mapping editorIDs to an editor extension registered with the workbench. An editor id is passed rather than an editor object to prevent the accidental creation of more than one editor for the same input. It also guarantees a consistent lifecycle for editors, regardless of whether they are created by the user or restored from saved data.

      The length of the input array and editor ID arrays must be the same. The editors are opened using pairs of { input[i], editorIDs[i] }.

      The mementos array mat be null but if not must match the input array in length. Entries in the mementos array may also be null if no state is desired for that particular editor.

      Parameters:
      inputs - the editor inputs
      editorIDs - the IDs of the editor extensions to use, in the order of inputs
      mementos - the mementos representing the state to open the editor with. If the supplied memento contains the input's state as well as the editor's state then the corresponding entries in the 'inputs' and 'ids' arrays may be null (they will be created from the supplied memento).
      matchFlags - a bit mask consisting of zero or more of the MATCH_* constants OR-ed together
      activateIndex - the index of the editor to make active or -1 if no activation is desired.
      Returns:
      references to the editors constructed for the inputs. The editors corresponding to those reference might not be materialized.
      Throws:
      MultiPartInitException - if at least one editor could not be created or initialized

    • getEditorState

      IMemento[] getEditorState(IEditorReference[] editorRefs, boolean includeInputState)
      Return an IMemento containing the current state of the editor for each of the given references. These mementos may be used to determine the initial state of an editor on a subsequent open.
      Parameters:
      editorRefs - The array of editor references to get the state for
      includeInputState - If true then the resulting memento will be contain the editor input's state as well as the editor's state.
      Returns:
      The array of mementos. The length of the array will match that of the refs array.
