      Parameters:
      filter - a filter.

    • setValidator

      public void setValidator(ISelectionStatusValidator validator)
      Sets an optional validator to check if the selection is valid. The validator is invoked whenever the selection changes.

    • updateOKStatus

      protected void updateOKStatus()
      Validate the receiver and update the ok status.

    • open

      public int open()
      Description copied from class: Window
      Opens this window, creating it first if it has not yet been created.

      If this window has been configured to block on open ( setBlockOnOpen), this method waits until the window is closed by the end user, and then it returns the window's return code; otherwise, this method returns immediately. A window's return codes are window-specific, although two standard return codes are predefined: OK and CANCEL.

      Overrides:
      open in class Window
      Returns:
      the return code
      See Also:

    • cancelPressed

      protected void cancelPressed()
      Handles cancel button pressed event.
      Overrides:
      cancelPressed in class Dialog

    • computeResult

      protected void computeResult()
      Description copied from class: SelectionStatusDialog
      Compute the result and return it.
      Specified by:
      computeResult in class SelectionStatusDialog

    • create

      public void create()
      Description copied from class: Window
      Creates this window's widgetry in a new top-level shell.

      The default implementation of this framework method creates this window's shell (by calling createShell), and its controls (by calling createContents), then initializes this window's shell bounds (by calling initializeBounds).

      Overrides:
      create in class SelectionStatusDialog

    • createDialogArea

      protected Control createDialogArea(Composite parent)
      Description copied from class: Dialog
      Creates and returns the contents of the upper part of this dialog (above the button bar).

      The Dialog implementation of this framework method creates and returns a new Composite with standard margins and spacing.

      The returned control's layout data must be an instance of GridData. This method must not modify the parent's layout.

      Subclasses must override this method but may call super as in the following example: 

       Composite composite = (Composite) super.createDialogArea(parent);
 //add controls to composite as necessary
 return composite;
      Overrides:
      createDialogArea in class Dialog
      Parameters:
      parent - the parent composite to contain the dialog area
      Returns:
      the dialog area control

    • createTreeViewer

      protected TreeViewer createTreeViewer(Composite parent)
      Creates and initializes the tree viewer.
      Parameters:
      parent - the parent composite
      Returns:
      the tree viewer
      See Also:

    • doCreateTreeViewer

      protected TreeViewer doCreateTreeViewer(Composite parent, int style)
      Creates the tree viewer.
      Parameters:
      parent - the parent composite
      style - the SWT style bits
      Returns:
      the tree viewer
      Since:
      3.4

    • getTreeViewer

      protected TreeViewer getTreeViewer()
      Returns the tree viewer.
      Returns:
      the tree viewer

    • access$superButtonPressed

      protected void access$superButtonPressed(int id)
      Set the result using the super class implementation of buttonPressed.
      Parameters:
      id - the id of the button that was pressed (see IDialogConstants.*_ID constants)
      See Also:

    • access$setResult

      protected void access$setResult(List result)
      Set the result using the super class implementation of setResult.
      Parameters:
      result - list of selected elements, or null if Cancel was pressed

    • handleShellCloseEvent

      protected void handleShellCloseEvent()
      Description copied from class: Window
      Notifies that the window's close button was pressed, the close menu was selected, or the ESCAPE key pressed.

      The default implementation of this framework method sets the window's return code to CANCEL and closes the window using close. Subclasses may extend or reimplement.

      Overrides:
      handleShellCloseEvent in class TrayDialog
