Polygrid sorting

[Paul Dupuis]

So, I bought the Summer Bundle. Yes, it is a good deal.

In my case it was primarily for the Polygrid widget. Our application 
uses a Datagrid to display customer research data. The columns headers 
are text and the left most column ROWs are test and all other cells are 
numbers. Some customers can have quite large data sets and I have been 
running into the number of columns (ad a default width of 100px per 
column) exceeding a GROUPs 32,767px width maximum (about 327-328 
columns). At this point the Datagrid just fails - no data is displayed.

I can now attest that a Polygrid (under LC 9.6.8) does not have this 
limit. I have a "test" stack (for Datagrid testing) I converted to the 
Polygrid and can easily generate 1000 columns x 1000 rows of data and it 
works.

So I guess the answer to bug 
https://quality.livecode.com/show_bug.cgi?id=23875 is "Use the PolyGrid"

On that note, the Datagrid has 2 features I use in this specific case, 
user column resizing (built into the Polygrid - Yea!) and column sorting 
(NOT built into the Polygrid - Boo!). So, does anyone have some column 
sort code for the Polygrid they have written that they might be willing 
to share?

Also, I have filled a Polygrid enhancement request to allow the left 
column (or the left N columns) to be locked/frozen, so they remain 
visible when the Polygrid is scrolled horizontally. See 
https://quality.livecode.com/show_bug.cgi?id=23880. If you might benefit 
from this enhancement, please follow the bug or add a comment to that 
effect.
