RCP Message Dialog

It looks like every time I need a message dialog in an Rich Client Platform (RCP) application, it takes me too much time finding which JFace dialog class is better for me...

This time I decided to post it here so that the next time I won't waste time.
All the methods needed are statically available in the org.eclipse.jface.dialogs.MessageDialog class:

• MessageDialog.openConfirm, for a confirmation dialog with an Ok/Cancel button set.
• MessageDialog.openError, for an error dialog with an Ok button.
• MessageDialog.openInformation, for an information dialog with an Ok button.
• MessageDialog.openQuestion, for a question dialog with and Yes/No button set.
• MessageDialog.openWarning, for warning dialog with an Ok button.
  

The org.eclipse.jface.dialogs.MessageDialogWithToggle is similar,but allows the user to adjust a toggle setting, like Yes Always/Yes/No or Yes/No/Never.

You can use org.eclipse.jface.dialogs.DialogSettings for a dialog setting, supporting loading and saving of properties in an XML file.

You can use org.eclipse.jface.dialogs.ProgressMonitorDialog to display progress during a long running operation.

And you can design your own dialog windows, just extend the org.eclipse.jface.dialogs.IconAndMessageDialog class.


Note: in RCP, you can get the shell using PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell();.
