  • Constructor Details

    • FilePropCnr

      public FilePropCnr()
      Creates a FilePropCnr for the designer with the specified name with a null value. This constructor is only used by the factory to check validity, and nothing else. Never instantiate this class.

    • FilePropCnr

      public FilePropCnr(Atom propertyAtom, IFile file)
      Creates a FilePropCnr for the designer with the specified name with a null value.
      Parameters:
      propertyAtom - the property atom.
      file - the file.

  • Method Details

    • fromProperty

      public static FilePropCnr fromProperty(GProp<?> property)
      Gets a FilePropCnr from a property that should be the FilePropCnr itself or a child.
      Parameters:
      property - The property.
      Returns:
      The FilePropCnr of the property, null if not found.

    • getDataContainer

      public PropCnr getDataContainer()
      Gets the data property container for the file.
      Returns:
      The data property container (Atom.DATA_CONTAINER), or null for none.

    • getSaveable

      public FilePropSaveable getSaveable()
      Gets the Saveable instance for this file.
      Returns:
      The Saveable instance, null when file hasn't been loaded yet (thus this call is too early and this shouldn't happen, otherwise the Editor requesting the Saveable has a problem with it's delayed start-up when projects are loaded or workbench started).

    • onCompletedLoading

      public void onCompletedLoading(PropCnr dataContainerToBe)
      Called when the file completed its loading from the Module model.
      Parameters:
      dataContainerToBe - The FilePropCnr data container to-be, not yet added, null for default.

    • onPropDispose

      protected void onPropDispose()
      Called when a property is disposed of by delete/remove in a container, or by the dispose method.

      This call is done just at the end of the delete/remove routine in the container, without synchronization.

      During this call, whatever components that e.g. the client needs to disposed of is done.

      Subclasses needing to perform some intelligent operations upon deletion should do it by overloading this method and always call the super.onPropDispose() method.

      Overrides:
      onPropDispose in class PropCnr

    • attachEditor

      public void attachEditor(PropEditorPart editor)
      Attaches an Editor to this file.

    • detachEditor

      public void detachEditor(PropEditorPart editor)
      Detaches an Editor from this file.

    • hasActiveEditors

      public boolean hasActiveEditors()
      Checks for active editors.

    • getAttachedEditors

      public PropEditorPart[] getAttachedEditors()
      Gets the attached editors.

    • getActiveEditor

      public PropEditorPart getActiveEditor()
      Gets the active or topmost attached editor.
      Returns:
      The editor part, or null for none.

    • getURL

      public URL getURL()

    • onEventSelf

      public void onEventSelf(GEvent event)
