scrollbar programming

[Rajashekar]

An array is having vertical scroolbar. I using more than two arrays where each will be having individual scrollbar. I want to use a common scrollbar for all the arrays where if I move the slide on the scrollbar the elements in all the arrays should move up or down depending on the scrollbar move.

Hello... 🙂

So you want to synchronize all scroll bars...? Is it so...?

Can you please explain in detail or post your code....?

Well, if all arrays should always scroll together, you might want to display your data in a 2D array or in a table instead. Would make more sense. 🙂

If you want to scroll all your 1D arrays with an external scrollbar, just place a naked scrollbar and use a "value change" event to update the "indexvals" preorty of all the arrays, for example as in the attached image.

Hi,

Make the scroll bar visible only for a single array and make all other array scroll bar as invisible. Then use the property node "Index Values"  of the visible scroll bar array to set to all other array Index Values.

Hope it helps you..

Create property nodes for the arrays and use the Index Values property.

Thanks for the help, I tried the logic in my program its working, I need one more information what is the max size of array?

Are 2,147,483,647 elements enough? You'll run out of memory on most systems before you get to an array that large, anyway, so it doesn't really matter.

I need 6,00,000 locations in an array to store 32 bit data in each location. Is it possible?

6,000,000 multiplied by 4 bytes comes out to ~24 MB. That's not a problem, as long as you don't make too many data copies.
