draw widgets and programming

description: 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? -Charles Bartels 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. -- -Charles Bartels
