Pre-computing scrollbar size to accomodate all the items in music collection

[Shivani Poddar <shivani poddar92 gmail com>]

Hi!

I am working on the bug ->https://bugzilla.gnome.org/show_bug.cgi?id=699832

I want to pre-compute the size of the scrollbar to indicate the total items in the collection (which are more than the ones we load in the application at one instance )

Need some ideas as to how do I tackle it.

Thankyou,

Shivani Poddar
