Inventory Filter

This dialog is used from several different places.  It's used to define a filter for finding or listing only particular items from the inventory database.

Nearly every field in the inventory database can be filtered using this function.  The "Reset" state will be no filtering at all (include all items) except inactive items.  Note that even a reset filter must have some things checked, so that all possible combinations of conditions are included (e.g. all cases of what taxes apply).

The filter selections should be simple enough to understand.  It's just a matter of figuring out which conditions you want to check.  Quantities can be filtered by any range (minimum and maximum values.  Keep in mind that all "Filter by" conditions selected must be met for an item to be included.  For instance if you enter both a price and a cost range, an item will not be included unless it meets both the price and the cost criteria.

To filter by class, category, park (if applicable) or vendor, just select the ones that you want to include -- use Ctrl-click to select multiple items.  If no items are selected, than that's actually the same as selecting none of them (all items cases be included).  You can filter by more than one field at a time also -- for instance to show only items belonging to a particular class and from a particular vendor.
