Hacking the GUI

If by "rotate" you mean like 3D then no way  ;-)

I mean using grab to move a large photo around on an iPad.
What had to be done was to disable/kill the scroller that lived in the same
space. There is a scrolling group of about one hundred rows that have
groups of: THUMBNAIL_MAGE - FIELD - FIELD

That scroller affected that Grab so it only worked for a small distance.

Clicking on the thumbnail brought up the following image which can be
increased/decreased in size.  This video does not show the scroller part
which gets disappears using  hide grp "AllItems"

I wanted them to be grabbed and moved so you can increase in size for
viewing details - that meant that  you needed to grab and drag parts back
into the view of the iPad as the image gets larger than the iPad space.
This is for a museum and they have items such as coins and clothing that
cannot be handled but details can be viewed by using this technique.

The following is recorded from the iOS simulator - using the iPad looks
much smoother.

So, that is what I meant by "spin".
