images.roi.CuboidMovingEventData class

Package: images.roi

Event data passed when the cuboid ROI is moving

Description

The images.roi.CuboidMovingEventData class is the class passed to listeners when a Cuboid ROI is moving. When the ROI class triggers an event using the notify handle class method, MATLAB® assigns values to the properties of an images.roi.CuboidMovingEventData object and passes that object to the listener callback function (the event handler).

The images.roi.CuboidMovingEventData class is a handle class.

Examples

collapse all

This callback function gets the event source object handle, the event name, and other properties from the images.roi.CuboidMovingEventData object passed to it when the event is triggered.

function myCallbk(s,evtData)
   eventSource = evtData.Source;
   eventName = evtData.EventName;
   previousCenter = evtData.PreviousCenter;
   currentCenter = evtData.CurrentCenter; 
   previousRotationAngle = evtData.PreviousRotationAngle;
   currentRotationAngle = evtData.CurrentRotationAngle;
end
