- All of the Xview pgmrs on Wall St want this kind of object too!
-
- The only thing that comes close is the Slingshots pkg.
- Slingshots has an Array_Tile xview object which you can put
- text/image items in each cell. But it does not (implicitly)
- have the row/column selection that you mention. Also, it might
- be very expensive to create 1000+ rows using slingshots. You
- may have to simulate the scrolling by replacing the text in the
- array_tile from your own data structures when you pan around.
-
- Be forewarned that Xview scrollbars are very problematic when
- the thing that you're scrolling is not pixel-based. You may
- have to use another mechanism to scroll the object (slider or
- some button images).
-
- Basically you have to build something on top of slingshots'
- array_tile.

- It's ironic that there's a table object in the OPEN LOOK specs
- (addison-wesley), but no implementation in XVIEW, OLIT or TNT!
-
- There's a decent Xt-based matrix object floating around, it'd be
- nice if there was a similar Xview object. Even Neuron Data's OIT
- has a multi-column list object!
