I find the current table fields just too clunky. I am creating a table object based on grouped fields. After a recent fix of a few bugs, it seems to work quite well, and allows for much better control.
The advantage to this approach is that it allowed me to do things like allow for a simple scheme for moving columns, inserting columns, proper tabbing, automatic vertical scrolling, etc... If anyone wants a copy of this object, just e-mail me, and I will be happy to send it to you. It work well right now - but I plan to keep modifying it and adding in new capabilities. For a table that needs to hold several hundred (or even several hundred thousand) rows, I am thinking of creating a different design - one that holds the data for each row in a custom property, and creates the fields/groups from the appropriate custom property for each row on the fly as the user scrolls up or down, then destroys those fields/groups as the row dissappears from view when it is scrolled past. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Sent: Friday, May 20, 2005 9:27 AM To: How to use Revolution Subject: Re: Table field behavior Wow -- can't we make this any more complicated? Thanks a whole lot. I will put your code in right now and start in as that automatic scroll thing is annoying as ^([EMAIL PROTECTED] (if you curse in unicode than no one will see).
