A behavior can request mouse capture through the behavior service by pushing itself onto the behavior stack with the PushCaptureBehavior method. If it does so, it will be notified through the OnLoseCapture method when capture is lost. Generally the behavior removes itself from the stack at this time. Capture is lost when one of the following actions occurs:

  • Someone else requests capture.

  • Another behavior is pushed.

  • This behavior is removed.

In each of these cases, OnLoseCapture will be called on the behavior.
