More like:
if (widget eq 'button_save') then begin
widget_control, pic, set_uvalue=image
endif
if (widget eq 'button_show') then begin
widget_control, pic, get_uvalue=image
tvscl, image, true=1
endif
But I wouldn't put "image" directly in the uvalue, I would put it my
state structure or whatever equivalent you are using.
