|
// CLASS DESCRIPTION (MConditionMessage)
|
|
//
|
|
// This class is used to register callbacks for changes to specific
|
|
// conditions and/or to determine the current state of a condition.
|
|
//
|
|
// The addConditionCallback method allows callbacks to be registered
|
|
// for the following messages:
|
|
// Condition Changed
|
|
//
|
|
// The first parameter passed to the add callback method is the
|
|
// name of the condition that will trigger the callback. The names of
|
|
// available conditions can be retrieved with the getConditionNames
|
|
// method.
|
|
//
|
|
// Callbacks that are registered for conditions will be passed an
|
|
// bool parameter that is the state of the condition.
|
|
//
|
|
// Each method returns an id which is used to remove the callback.
|
|
//
|
|
// To remove a callback use MMessage::removeCallback.
|
|
//
|
|
// All callbacks that are registered by a plug-in must be removed by that
|
|
// plug-in when it is unloaded. Failure to do so will result in a fatal error.
|
|
//
|
|
// The getConditionState method is used to return the current status
|
|
// of the specified condition.
|
|
