The function isType should generally be used by all elements to check the type of a drop operation. It automatically causes further data reads from the object to return information from a matching base object. This functionality is also utilized by the framework, i.e. a custom drag with a supported base data item available in the chain can be used with an out of the box framework element. The currently active data is called top level data. Special cases requiring a rewind of the inheritance chain can use the resetType function.
When drag objects are set using the setData function, here is the expected format of the LUA table used to define the drag object:
...
type (string) [optional]
The type applied to the created base dragdata
Return values
(dragdata)
Returns a dragdata object representing the created base data object.
