The newer (possibly more elegant) solution uses the event information. Using the UIFigure UIFigureWindowButtonDown callback, the event object passed to the callback has information on the source of the event (mouse click), in this case the UIFigure. Then you can directly access the SelectionType property. For example
% Window button down function: UIFigure
function UIFigureWindowButtonDown(app, event)
switch event.Source.SelectionType
case 'normal'
% Do left button stuff
case 'alt'
% Do right button stuff
case 'extend'
% Do center button stuff
end
end
