<body class='hmmessage'><div dir='ltr'>Hi!<br>I would like to draw a spline in a qvtkwidget, but without preset points, just during the interaction.<br>What I mean is just the user clicks a button where to start drawing a spline, and then begin the drawing by clicking on the qvtkwidget.<br>Then when finished, just double click or anything else to stop drawing.<br>Where should I start with?? How can I handle a spline?<br>Thanks!<br>                                            </div></body>
