draw widgets and programming [message #4528]

Hi,

I'm currently trying to write a widget program using the widget
builder. I had no problem actually getting the template of the widget
made. What I'm having trouble with is connecting the program to the
widgets. Specifically, having a "button press" event wset to a draw
widget and then plotting some data. The widget *.pro contains the
lines:

COMMON DRAW5_Comm, DRAW5_Id
WIDGET_CONTROL, DRAW5, GET_VALUE=DRAW5_Id

when the button event is pressed I tried to

wset, DRAW5_Id
etc...

but that didn't work at all. IDL said that the variable "DRAW5_Id"
was undefined.

Does anyone know what the problem is?

p.s. Thanks to everyone who told me where to find the "irafrd"
procedure. I tried to e-mail everyone who answered my question but
some of the mail bounced.
