Auto-scaling scrollbars

[Lonesome Ducky]

Most scrollbars I've seen scale the button in the middle depending on how much you can scroll. In irrlicht, the button stays the exact same size no matter what. I tested my own revision of the scrollbar, scaling the button to the width of the scrollbar divided by the range. It was extremely easy, and made it far easier to tell how much it could scroll. Are there any plans to change the scrollbar to something like that, or will it stay the same?

Maybe, I wrote a patch for that once (but old Irrlicht version and back then I didn't realize yet how much patches suck which do more than one single thing: http://www.michaelzeilfelder.de/irrlich ... ures.patch), but it hasn't been too high on my priority list so far. So basically I like it and it's probably not too much work adding it (well, some work for writing tests first) once I get to it.

That's good! And if I can make a suggestion if you do add it at some point, can you make the button scale not just by the total range, but say by the range divided by a user defined number? Because say you wanted a really smooth scrollbar, so you set the max really high. With scaling just on the range, the button would be tiny, but maybe you don't have a whole lot to scroll through. But if the user could define that divisor, you could have a really smooth scrollbar and a button that shows how much there really is to scroll.

I think I simply used a min-size in my patch which could be set.

Well I mean, take the scrollbar on your browser for example. It has that really smooth movement, but a large button. To get the smooth movement like that in irrlicht, you'd have to set the max of the scrollbar really high, and doing so would make the button small. I'm proposing something that allows for a high max, but a button that takes up maybe half the scrollbar. So instead of deciding the width of the scrollbar by dividing the scroll length by the range, maybe divide the scroll length by the range that is itself divided by a user defined number. This way you could have a max of say, 10000, and change that number so your button can still take up half the scrollbar. Sorry if my explanation isn't very clear, and I don't want to sound like I'm demanding anything either

Ok, I'll read & think about it again when I get to it, probably makes sense when I start doing a few tests ;-)
