Here is the call graph for this function:

inlineoverridevirtual |
Returns the type of an item as an int.
All standard graphicsitem classes are associated with a unique value; see QGraphicsItem::Type. This type information is used by qgraphicsitem_cast() to distinguish between types.
The default implementation (in QGraphicsItem) returns UserType.
To enable use of qgraphicsitem_cast() with a custom item, reimplement this function and declare a Type enum value equal to your custom item's type. Custom items must return a value larger than or equal to UserType (65536).
For example:
Reimplemented from QGraphicsItem.
