Display message boxes For some applications, you'll want to display a message box to inform the user of something that has or might occur. Adding a message box To add a message box to your application: 1. Go to a Composition Editor open on a visual part in your application. 2. Select (Prompter category) and (Message Prompter part). 3. Click on the free-form surface. Changing the settings for the message box Define what the message box displays by changing its settings: 1. Open the Message Prompter part's Properties window. 2. Specify the iconType, title, messageString, and buttonType. Connecting the message box to other parts After you define a message box, you make an event-to-action connection so the message box displays when the event occurs. Connect the event, such as clicked for a push button, to the prompt action of the Message Box part.
