Examples of IMessageManager

org.eclipse.ui.forms.IMessageManager

This interface provides for managing typed messages in a form. Typed messages are messages associated with a type that indicates their severity (error, warning, information). The interface is responsible for:

Bridging the concept of typed messages and control decorations
Adding one or more messages per control in a form
Rolling the local messages up to the form header
Adding one or more general messages to the form header

To use it in a form, do the following:

For each interactive control, add a listener to it to monitor user input
Every time the input changes, validate it. If there is a problem, add a message with a unique key to the manager. If there is already a message with the same key in the manager, its type and message text will be replaced (no duplicates). Note that you add can messages with different keys to the same control to track multiple problems with the user input.
If the problem has been cleared, remove the message using the key (attempting to remove a message that is not in the manager is safe).
If something happens in the form that is not related to any control, use the other addMessage method.

This interface should only be referenced. It must not be implemented or extended.
