create callback for canvas

[popcorn]

i load an image on a canvas. now, i want to have a callback function associate with this canvas. usually, callbacks are generated by right click the control and click generate control callback. but, for canvas, the generate option is not available. so, how do i create a callback function for canvas? i tried to use InstallCtrlCallback. but, im not successful. anyone, please help.

thanks

Hello popcorn.

Before CVI can generate the callback function for any control, you need to specify the function name in the Edit Control dialog.
