Real Object Inventory To Dialog

De DigiWiki.

This script will display all items contained in an Object Inventory, regardless of the amount of items or length of item names. Further more, this script allows you to determine who has access to the Object using this script. It also provides an easy way to configure end, next and back buttons. I have used non standard unicode characters for my buttons in this example (characters that cannot be part of an item name). A simple giver has been implemented, which checks your permissions on any selected Inventory Item to see if it's actually transferable.

If the Owner uses the object, the above check is not done.

Apart from displaying content in a dialog, this script demonstrates several techniques that are useful in many ways.
