Interface IFormPage

  • All Superinterfaces:
    IAdaptable, IEditorPart, ISaveablePart, IWorkbenchPart
    All Known Implementing Classes:
    FormPage
    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.

    3.0
