Re: Slider values
Well done Brian. Yes, setting the (invisible) lineIncrement property to zero fixes the numbers. I didn't notice that the little ticks were wrong. I don't know how to fix them. Your initial comments regarding a new user are exactly my sentiments. There are a couple of bugs in scrollbar objects in addition to such unexpected behaviour. I would like to see them cleaned up substantially at some stage. They are awkward to use in any quantitative way because their lineInc, pageInc and numberFormat properties are all interlinked. What do these number series have in common, and what is the underlying pattern? a: 1,2,3,4,5,6,7,8,8,9,10; b: 1,10,20,29,38,48,57,67,76. The answer is they are the series of values that you get when you click on the bar of (a) a fresh, unadjusted slider control, and (b) a slider with its On bar click value (pageInc property) set to 10. Here is a challenge: Make a slider control that starts at 0 and increments by exactly 10 when you click on the bar, up to 100. It is certainly possible, but not easy if you don't know the trick.

Lew Setting the lineIncrement property to 0 seems to solve it... except: a) I had to discover lineIncrement and set it by script b) The ticks marks are wrong So, what IS the trick? -- Michael J.

Re: Slider values
Agreed. I can suggest two simple changes that seem as though they would make sliders work out of the box: 1) Change the default lineIncrement to 0 for slider style objects 2) There appears to be an engine bug with the number of ticks displayed (at least on MacOS X). There is one too few. For example, for a slider with values from 0 to 100, pageInc = 10 and lineIncr = 0 (as described in this thread), it displays 10 ticks. There should be 11: 0,10,20,30,40,50,60,70,80,90,100, My guess is that somewhere the engine is doing something like: numTicks = (maxValue - minValue)/(pageIncrement - lineIncrement) This seems intuitively ok at first (100 divided by 10!) but it should actually be the above plus 1, since you want ticks at both the min and max values. As it is now, what you get is a slider that stops on 10,20,30,etc but the ticks marks are actually at 11,22,33,44,55,etc - which looks very awkward. I'll BugZilla #2 as an engine bug unless someone else sees something here, but as far as I can tell it makes it impossible to properly display a slider, since paging left and right misses the ticks completely! - Brian Well done Brian.

Re: Slider values
Eric, This is helpful. I do, however, think it should still be considered a bug that one needs a special script in order to correct how sliders work when created in the IDE. Plus, since the script below actually modifies the pageIncrement away from what you originally intended, you again will have to do some funny calculation if you rely on the actual numeric value of the thumbPos. A very helpful stack to get people unstuck, but this really is both an IDE and an engine bug IMO. - Brian Hi Michael and Brian, May be you could have a look to my How-To stack How to manage scrollbars (available through Tutorials Picker: see my website).

Perhaps this is the problem. This could be related, but I don't think it will help the ticks. The actual number of ticks marks is wrong, and I don't think that can be affected by changing the thumbSize. I could be wrong, but that would just add more credence to needing to have this work by default =)! - Brian ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

Re: Slider values
Well that certainly is interesting- it appears that setting pageInc to 10 actually gets your slider to increase by 9.375 at a time.

What do these number series have in common, and what is the underlying pattern? a: 1,2,3,4,5,6,7,8,8,9,10; b: 1,10,20,29,38,48,57,67,76.
