Grabbing <constraint> in templated jnl file
LAS users,
I'm finally upgrading an old V5.1 LAS to 6.2. I have a variable for
which I want the user to be able to specify one parameter (besides the
usual space-time constraints) which will be used to rotate the variable
by a specified angle. I have the <constraint> element of the <map>
element working so that the user can enter the parameter on the
constraints page. I also see how, in the insitu example in the contrib
directory, how such custom constraints were passed to custom operations.
What I was wondering, however, is if there is a way to directly grab
the user specified constraint for use in a Ferret journal template (In
v5.1 it was easy to do with cookies). I don't really need a new
operation, I just need to rotate the variable by the user entered
value. The line I'm using in my ui.xml file is:
<map type="ops" ......
<ifmenu ...
<ifmenu ...
<constraint type="textfield" name="Rotation_angle" label= "Enter
Rotation Angle:" required="true">
</constraint>
</map>
What I was hoping is that there is a way to use something like:
let rotation_angle = [% args.constrain0_text %]
in my Ferret journal file, but I don't know what the argument is
called. Or is the only way to do it by writing a custom operation?
(This wouldn't be a huge problem, I was just hoping the extra step
wasn't necessary).
Thanks! Lynn
