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).

Since:
3.0

buttonPressed

protected void buttonPressed(int buttonId)

Overrides:
buttonPressed in class MessageDialog
Parameters:
buttonId - the id of the button that was pressed (see IDialogConstants.*_ID constants)
See Also:
Dialog.buttonPressed(int)

createButtonsForButtonBar

protected void createButtonsForButtonBar(

createButtonsForButtonBar in class MessageDialog
Parameters:
parent - the button bar composite
See Also:
Dialog.createButtonBar(Composite)

createDialogArea

protected

the dialog area control
See Also:
Dialog.createDialogArea(Composite)
