--Apple-Mail-F3ED7DFA-4C23-45AF-A7B2-EAA38DAC83A0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable I gave you a pretty simple and easy answer yesterday. The reality is you nee= d to only make calls to graphics in the paint event.=20 Again here are my suggestions: 1.) Draw into a picture property in your MouseDown event. Paint the picture i= n the canvas paint event. You can access the canvas property of a picture.=20= 2.) Put York drawing code in MouseDown into a method with the graphics objec= t as a parameter. Add a MouseDwn Boolean property to your canvas. Set MouseD= wn to True when the Mouse is down and false when up. Call Refresh or Invalid= ate when the mouse state changes. In the Paint event check for MouseDwn bein= g true. If it is then call your method. Pass the graphics parameter into the= method.=20 These are two simple ways to do what you want.=20 It=E2=80=99s been years now since Xojo has said that you should not access t= he Graphics object outside the paint event.
