Class MessageDialogWithToggle

All Implemented Interfaces:
IShellProvider

public class MessageDialogWithToggle extends MessageDialog

A message dialog which also allows the user to adjust a toggle setting. If a preference store is provided and the user selects the toggle, then the user's answer (yes/ok or no) will be persisted in the store. If no store is provided, then this information can be queried after the dialog closes.

This type of dialog should be used whenever you want to user to be able to avoid being prompted in the future. It is strongly recommended that a cancel option be provided, so that the user has the option of making the decision at a later point in time. The semantic for a cancel button should be to cancel the operation (if it has not yet started), or stop the operation (if it has already started).

It is the responsibility of the developer to provide a mechanism for the user to change this preference at some later point in time (e.g., through a preference page).

    • buttonPressed

      protected void buttonPressed(int buttonId)
      Description copied from class: Dialog
      Notifies that this dialog's button with the given id has been pressed.

      The Dialog implementation of this framework method calls okPressed if the ok button is the pressed, and cancelPressed if the cancel button is the pressed. All other button presses are ignored. Subclasses may override to handle other buttons, but should call super.buttonPressed if the default handling of the ok and cancel buttons is desired.

      Overrides:
      buttonPressed in class MessageDialog
      Parameters:
      buttonId - the id of the button that was pressed (see IDialogConstants.*_ID constants)
      See Also:
    • 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 MessageDialog
      Parameters:
      parent - the button bar composite
      See Also:
    • createDialogArea

      protected Control createDialogArea(Composite parent)
      Description copied from class: MessageDialog
      This implementation of the Dialog framework method creates and lays out a composite and calls createMessageArea and createCustomArea to populate it. Subclasses should override createCustomArea to add contents below the message.
      Overrides:
      createDialogArea in class MessageDialog
      Parameters:
      parent - the parent composite to contain the dialog area
      Returns:
      the dialog area control
      See Also:
