Interface IFormPage

All Superinterfaces:
IAdaptable, IEditorPart, ISaveablePart, IWorkbenchPart
All Known Implementing Classes:

public interface IFormPage extends IEditorPart
Interface that all GUI pages need to implement in order to be added to FormEditor part. The interface makes several assumptions:
  • The form page has a managed form
  • The form page has a unique id
  • The form page can be GUI but can also wrap a complete editor class (in that case, it should return true from isEditor() method).
  • The form page is lazy i.e. understands that its part control will be created at the last possible moment.

Existing editors can be wrapped by implementing this interface. In this case, 'isEditor' should return true. A common editor to wrap in TextEditor that is often added to show the raw source code of the file open into the multi-page editor.

  • Method Details

    • initialize

      void initialize(FormEditor editor)
      editor - the form editor that this page belongs to
    • getEditor

      FormEditor getEditor()

      the managed form or null if this is a source page.
    • setActive

      void setActive(boolean active)
      Indicates whether the page has become the active in the editor. Classes that implement this interface may use this method to commit the page (on false) or lazily create and/or populate the content on true.

    • isActive

      boolean isActive()

      true for active page.
    • canLeaveThePage

      boolean canLeaveThePage()
      Tests if the content of the page is in a state that allows the editor to flip to another page. Typically, pages that contain raw source with syntax errors should not allow editors to leave them until errors are corrected.
      true if the editor can flip to another page, false otherwise.
    • getPartControl

      Control getPartControl()
      Returns the control associated with this page.
      the control of this page if created or null if the page has not been shown yet.
    • getId

      String getId()
      Page must have a unique id that can be used to show it without knowing its relative position in the editor.
      the unique page identifier
    • getIndex

      int getIndex()
      Returns the position of the page in the editor.
      the zero-based index of the page in the editor.
    • setIndex

      void setIndex(int index)
      Sets the position of the page in the editor.
      index - the zero-based index of the page in the editor.
