public abstract class SelectionDialog extends TrayDialog
The abstract implementation of a selection dialog. It can be primed with initial selections (setInitialSelections), and returns the final selection (via getResult) after completion.

Clients may subclass this dialog to inherit its selection facilities.

  • Constructor Details

    • SelectionDialog

      protected SelectionDialog(Shell parentShell)
      Creates a dialog instance. Note that the dialog will have no visual representation (no widgets) until it is told to open.
      Parameters:
      parentShell - the parent shell

  • Method Details

    • configureShell

      protected void configureShell(Shell shell)
      Description copied from class: Window
      Configures the given shell in preparation for opening this window in it.

      The default implementation of this framework method sets the shell's image and gives it a grid layout. Subclasses may extend or reimplement.

      Overrides:
      configureShell in class Window
      Parameters:
      shell - the shell

    • createButtonsForButtonBar

      protected void createButtonsForButtonBar(Composite parent)
      Description copied from class: Dialog
      Adds buttons to this dialog's button bar.

      The Dialog implementation of this framework method adds standard ok and cancel buttons using the createButton framework method. These standard buttons will be accessible from getCancelButton, and getOKButton. Subclasses may override.

      Note: The common button order is: {other buttons}, OK, Cancel. On some platforms, Dialog.initializeBounds() will move the default button to the right.

      Overrides:
      createButtonsForButtonBar in class Dialog
      Parameters:
      parent - the button bar composite

    • createMessageArea

      protected Label createMessageArea(Composite composite)
      Creates the message area for this dialog.

      This method is provided to allow subclasses to decide where the message will appear on the screen.

      Parameters:
      composite - the parent composite
      Returns:
      the message label

    • getInitialSelections

      @Deprecated protected List getInitialSelections()

      use getInitialElementSelections() instead
      Returns the initial selection in this selection dialog.
      Returns:
      the list of initial selected elements or null

    • getInitialElementSelections

      protected List getInitialElementSelections()
      Returns the list of initial element selections.
      Returns:
      List

    • getOkButton

      public Button getOkButton()
      Returns the ok button.
      Returns:
      the ok button or null if the button is not created yet.

    • getResult

      public Object[] getResult()
      Returns the list of selections made by the user, or null if the selection was canceled.
      Returns:
      the array of selected elements, or null if Cancel was pressed

    • setInitialSelections

      public void setInitialSelections(Object... selectedElements)
      Sets the initial selection in this selection dialog to the given elements.
      Parameters:
      selectedElements - the array of elements to select

    • setInitialElementSelections

      public void setInitialElementSelections(List selectedElements)
      Sets the initial selection in this selection dialog to the given elements.
      Parameters:

    • setDialogBoundsSettings

      public void setDialogBoundsSettings(IDialogSettings settings, int strategy)
      Set the dialog settings that should be used to save the bounds of this dialog. This method is provided so that clients that directly use SelectionDialogs without subclassing them may specify how the bounds of the dialog are to be saved.
      Parameters:
      settings - the IDialogSettings that should be used to store the bounds of the dialog
      strategy - the integer constant specifying how the bounds are saved. Specified using Dialog.DIALOG_PERSISTLOCATION and Dialog.DIALOG_PERSISTSIZE.
      Since:
      3.2

    • getDialogBoundsSettings

      protected IDialogSettings getDialogBoundsSettings()
      Gets the dialog settings that should be used for remembering the bounds of the dialog, according to the dialog bounds strategy. Overridden to provide the dialog settings that were set using setDialogBoundsSettings(IDialogSettings, int).
      Overrides:
      getDialogBoundsSettings in class Dialog
      Returns:
      the dialog settings used to store the dialog's location and/or size, or null if the dialog's bounds should not be stored.

    • getDialogBoundsStrategy

      protected int getDialogBoundsStrategy()
      Get the integer constant that describes the strategy for persisting the dialog bounds. Overridden to provide the dialog bounds strategy that was set using setDialogBoundsSettings(IDialogSettings, int).
      Overrides:
      getDialogBoundsStrategy in class Dialog
      Returns:
      the constant describing the strategy for persisting the dialog bounds.
      Since:
      3.2

    • isResizable

      protected boolean isResizable()
      Description copied from class: Dialog
      Returns a boolean indicating whether the dialog should be considered resizable when the shell style is initially set.

      This method is used to ensure that all style bits appropriate for resizable dialogs are added to the shell style. Individual dialogs may always set the shell style to ensure that a dialog is resizable, but using this method ensures that resizable dialogs will be created with the same set of style bits.

      Style bits will never be removed based on the return value of this method. For example, if a dialog returns false, but also sets a style bit for a SWT.RESIZE border, the style bit will be honored.

      Overrides:
      isResizable in class Dialog
      Returns:
      a boolean indicating whether the dialog is resizable and should have the default style bits for resizable dialogs
      Since:
