Using *callbackData (again)

[Marianne]

My question concerns using the void *callbackData parameter in the GUI-generated callback functions in CVI (6.0). I know how to assign the callbackData to certain controls (using SetCtrlAttribute(..., ..., ATTR_CALLBACK_DATA, ...) ...but is there a way to assign the callbackData to a certain FUNCTION? I have several controls on my panel that call the same function with the same callbackData. It would be nice if I could assign the callbackData to the function using one line of code, rather than the several lines of code I need to assign the callbackData to each and every control.

Is there a away to do this?

Thanks is advance,

No, you have to set it by control. You would have to call a SetCtrlAttribute for each control using the callback.

Chris,

I had a feeling that was the case but I thought I'd ask anyway. Thanks for the speedy reply!
