This is my code for updating a dynamic 'thumbnail' scroll group. In CreateThumbnailGroup(), you'll see that I prepass the folder items to get the maximum width for the ScrollGroup GROUP_THUMBNAIL_SCROLL. Of course, this endeavor doubles the time it takes to load all of the bitmaps (as they are loaded twice - once for calculation, once to set the BitmapButton). Is there any way that the group's width could be set after the fact to avoid the prepass? Or would you suggest just getting the count of elements that 'might' have a bitmap and preallocating an array of BaseBitmap which is then disposed of upon exiting CreateThumbnailGroup()?

To respond to this myself, I could not find a way to 'reset' the ScrollGroup width after the fact. There might be a way, but the docs are inprecise about how this could be done.

Instead, the BaseBitmap array was used to store all of the bitmaps during the width calculation phase and then these set to the BitmapButtons instead of reconstructing the image path and reloading the image into a generic bitmap. This means that the width calculation variation is about as fast as the non-calculation instead of taking twice the time.

That's about as good as it gets. Now if the developers would make image loading into bitmaps a little faster (as that is my main bottleneck here from testing) users of my plugin would be elated.

Thanks,
