Hi everybody,
i am using david fannings fsc_field. I initialize the field in the
following way
param_text = fsc_field(textbase,title=param_labels(i), value = double
(0.0),Decimal=2,LabelSize= 55,/noedit,xsize=9,$
uname = param_labels(i), /highlight,/frame,/
cr_only,uvalue=i,event_pro='setparam')
if a user selects a certain option in my gui the fields should become
editable and set to default values defined as double default = double
(1000) e.g.
textID = widget_info(event.top,find_by_uname=param_labels(i))
widget_control, textID, set_value=default, editable=editable
However even though i initialized the field with a double idl
complains that it is unable to convert double to string.
WIDGET_CONTROL: String expression required in this context: DEFAULT
Since the field is not set to a different value before i don't
understand what is going wrong here
Thx
Andi
