Re: invalid CGContextRef in custom HIView in PDE

hi,

i have written an application hosted pde to add additional drawing and layout configuration options while printing.  The pde loads correctly, it contains several standard controls (checkboxes and popup buttons) which all work correctly;  however, there is one problem.  i have a custom HIView that wishes to do some custom drawing using CG.  inside the draw event handler, the call to get the CGContextRef is failing with:

                    CGContextRef context;

                    

                    status = GetEventParameter(event, 

                                               kEventParamCGContextRef, 

                                               typeCGContextRef,

                                               NULL, 

                                               sizeof(context),

                                               NULL, 

                                               &context);

                    

-9870 eventParameterNotFoundError

can i use a custom HIView in a pde?  are there any tutorials for this?

regards,

marquis
