Hi all,
I'm having a very weird problem in IDL.
I have a large widget base program which is calling the IDL function CW_FSLIDER, among others using the keyword uname.
However IDL complains that % Keyword UNAME not allowed in call to: CW_FSLIDER
This has worked for me before on a linux machine running IDL 7. I am now on a mac running IDL 8.2
I have checked the documentation, and even the .pro file in the lib directory, and UNAME is a valid keyword, and it is also used appropriately. I'm really at a loss on what could be wrong.
Cheers,
Søren

Unfortunately I'm not sure of anything. I have no experience on writing widget based idl programs, and is merely using somebody else's code :-(
the only thing I know for sure is that it did work once upon a time, but I'll try to have a look at what you're suggesting.
I am however still very puzzled about the way in which this is failing. If I try to call CW_FSLIDER from the prompt it will complain that the widget specifier is invalid (clear enough, I'm not giving it a proper input). If I then give it the uname keyword it'll mention nothing about the invalid widget specifier, but go straight to uname not allowed in call to CW_FSLIDER. I still think that is very strange :-|

Ah, then forget about debugging and start thinking about strategies for
getting back at the SOB. ;-)

My guess is the widget ID doesn't point to the widget you think it does.
You might be able to use WIDGET_INFO and its various keywords to gather
information about the widget and see if you can figure out what is going
on. The CW_FSLIDER widget should be a base widget (use the TYPE
keyword). There is no question the code assigns a UNAME to this widget,
so the reason you can't find it appears not to be the fault of the
CW_FSLIDER program itself. :-)
Cheers,
David

For those who are interested I tried running the widget on my old linux machine using idl 8.2, and it works flawlessly. It thus seems that some IDL widget programming is platform specific.
Also, thank you for the additional info David :-)
Cheers,
Søren
