Dear All,
I have one window with a collection of button, text, draw and label
widgets (in one base widget) and would like to know if there is a way
of printing it. I tried to get the value (id) of the base widget to
try to use David Fanning's TVREAD routine, but you cannot call the
get_value parameter on a widget_base. Has anyone been able to do this
or does anyone know what the correct way to do it? My routine is quite
lengthy because there are so many widgets so I will not include it but
I can put it up if you would like. Thanks.
Ryan.

Ryan,
Here's a procedure that uses import (from ImageMagick) to capture
a top level base. It helps to know the title of the base widget
as well as the widget id - then it is entirely automatic.
Otherwise you'll need to select the window with the mouse. (does
anyone know how to get the title of a base widget in IDL?)
Note that the type of file that you are capturing to is
determined by the extension of the filename: .ps for postscript,
.pdf for pdf, .jpg for jpeg, and so on.
Hope this helps, Mike
pro import_tlb, widget_id, filename, title=title
;; Bring the widget to the front:
widget_control, widget_id, iconify=0
;; If we know the window title, then capture it directly, otherwise
;; use what the user selects:
if n_elements(title) eq 1 then begin
cmnd = 'import -screen -window "' + title + '" ' + filename
endif else begin
cmnd = 'import -screen ' + filename
endelse
spawn, cmnd, result
print, result
end

I think it will capture the foremost window. If you've selected
another window with the same title, I think you'll get that one.

That's good to know!
