Could this same effect not be accomplished with a scrolling group containing locked text fields stacked on top of each other?
The background color of the locked text fields could be anything you want. With that, there would be no need for any scripting to keep the background synched up with the line - when you scroll the group, it would all be automatic. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sarah Reichelt Sent: Tuesday, March 08, 2005 5:20 PM To: [email protected] Subject: Alternating stripes in fields Dear list, There have been seveal attempts to emulate iTunes-like alternating stripes as backgrounds for scrolling fields in Revolution. I started with a stack posted by Malte Brill (Thanks Malte) and made some changes. Here is my technique and the required scripts: ------------------------------- Make a graphic with alternating stripes the height of the field's textHeight. It must be at least twice as high as the scrolling field. Import it into the stack and group it into a single item group. Resize the group to the size of the field and position over the field, then lock it's location. Send group to back & position accurately, making it a few pixels smaller if required. Move up & down one or two pixels to line up with text after the initialization script has run once. In these scripts, the striped graphic group is called "StripesGroup" and the scrolling field is called "Scroller" -- put this in preOpenCard handler -- initialize scrolling striped background -- set the vscroll of fld "Scroller" to 0 set the vscroll of grp "StripesGroup" to the effective textHeight of fld "Scroller" * 2 -- put these in the field script -- on scrollBarDrag setStripeScroll end scrollBarDrag -- called by scrollBarDrag in scrolling field -- on setStripeScroll put the vScroll of me into tScroll put the effective textHeight of me into tHeight put tHeight * 10 into tSkip -- change this to 6 or so if there are less than 7 lines visible put (tScroll div tSkip) + 1 into tScrollLoop put tScrollLoop * tSkip into tCorrect put tScroll + tSkip - tCorrect + (tHeight * 2) into newScroll if newScroll > tSkip then subtract tSkip from newScroll set the vScroll of grp "StripesGroup" to newScroll end setStripeScroll _______________________________________________ use-revolution mailing list [email protected] http://lists.runrev.com/mailman/listinfo/use-revolution _______________________________________________ use-revolution mailing list [email protected] http://lists.runrev.com/mailman/listinfo/use-revolution
