Interface CommandSource

All Known Implementing Classes:

CommandSourceAdapter

public interface CommandSource

A CommandSource represents a source of a command, such as a MenuItem or Toolbar Button. A CommandSource may have a CommandTarget associated with it. The CommandTarget represents the command that will be fired when the CommandSource is activated. Typically a CommandTargetManager is responsible for setting the CommandTarget. The CommandSource will typically be dimmed out if either there is no CommandTarget associated with it, or if the CommandTarget is not enabled.
