Re: Setup a Scrollbar?
Hi Scott, My problem is getting the thumb correctly sized so, for example, if the field holds 14 items and the lines number 15, you get a fairly large thumb, instead of the tiny version when its size is set to 1. If you are working with a scrolling field, the thumbSize adjusts automatically to the amount of text in the field. Create a scrolling field with the formattedHeight of the text = to the the field's adjusted height...there will be no visible thumb. Add one line of text and you have a fat thumb that gets slimmer with each line added to the field. If you are using a scrollBar control instead of a scrolling field, this works for moi: set the thumbSize of scrollBar Index Scroll to trunc(maxSize*(visibleLines/linesOfImages)) get visibleLines * imageHeight set the pageInc of scrollBar Index Scroll to it set the lineInc of scrollBar Index Scroll to imageHeight Rob Cozens CCW, Serendipity Software Company And I, which was two fooles, do so grow three; Who are a little wise, the best fooles bee. from The Triple Foole by John Donne (1572-1631) ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: Setup a Scrollbar?
Malte, Scott, et al: pageInc: 1 lineInc: 1 From Rev Dictionary: Use the pageIncrement property to change the amount that is scrolled when the gray region is clicked. Use the lineIncrement property to change the amount that is scrolled when the scrollbar arrows are clicked. Do you really want the scroll limited to one pixel in these cases? lineInc should = the height of one line of scrolling text or objects pageInc should = lineInc * the number of visible lines of text or objects Rob Cozens CCW, Serendipity Software Company And I, which was two fooles, do so grow three; Who are a little wise, the best fooles bee. from The Triple Foole by John Donne (1572-1631) ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Setup a Scrollbar?
Is there a document/recipe somewhere to set up the properties of a scrollbar such that its thumb correctly syncs with the scroll of a field? I know I've done this before somewhere but for some reason I seem to be off on a current project in how I'm figuring the start and end values.

Re: Setup a Scrollbar?
Hi scott, try: startValue: 0 endValue: formattedheight of fld - height of fld - margins of fld (if 1 no scroll) pageInc: 1 lineInc: 1 thumbSize: 1 Hope that helps, Malte ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Re: Setup a Scrollbar?
Scott, I think the trick is that you have to also increase the endValue when you increase the thumbSize (not very intuitive, I know). Try this. Set: startValue: 0 endValue: 100 Now scroll all the way down and check the thumbPosition... it's 67, not 100. So you probably want something more like: endValue = 100*( (height of fld 1/(formattedHeight of fld 1 - height of fld 1))+1) thumbSize = endValue *(height of fld 1)/(formattedHeight of fld 1) For example, if you formattedHeight is 150 and your field is 50, you get: endValue = 100 * (1 + 50/100) = 150 thumbSize = 150 * (1 / 3) = 50 And so you have a thumb which is 1/3 the height of the scrollbar - same as the field is 1/3 the height of it's contents.

Unfortunately, I'm still getting inconsistent results. Sometimes the scrollbar scrolls correctly to the end of the field contents, other times, the scroll falls short. Not sure what's going on (bug in my code, bug in Rev, incorrect proportion, etc). I'll continue to try to figure it out.

Re: Setup a Scrollbar?
Hrm. Any chance it's a rounding / trunc problem? If so you could increase the resolution by jumping from a 0-100 base scale to something more like 0-10 to make the truncating negligible. How much is getting cut off / what are your actual values? Just a shot in the dark...!
