Greetings,
I do not have a lot of experience
with objects in IDL, and could use
some advice from experienced IDLers.
I am writing a piece of code that
will have about 2000-10,000 strings each of length
500 characters (for instance), and
I'd like to display them in a window
in a number of different ways. (ie a
selected subset of the strings, sorted in
a different manner, etc).
Would it be insane to make all the 2000 (or more)
strings graphic text objects?
- would it be too slow? (I want lickedy-split
user manipulation of the strings, of which
only 30 to 50 of which would be on screen
at any time)
- it seems a bit of overkill, since I will
just be displaying the text, and not rotating
the text in 3D, although I probably will do that
just to annoy the user, and amuse myself! ;)
- I'll be doing a widget interface to display
the strings, and let the user interact.
- I want to be able to scroll through the
entire list, so a text widget seems like
a possible way to go, but I do want to
be able to select a particular string by clicking
on it, and having operations performed based on
the selection. For instance, I'll want to change
the colour and font of the selected string, modify
that one in another window etc.
thanks for any insight,
cheers,
bob
