Variant Based Canvas Example

This example demonstrates how to use the QtVariantPropertyManager convenience class for all property types. In this approach only one instance of the property manager class is used, and the developer interfaces with a dynamic API based on QVariant.

The example presents a canvas filled up with items of different types, and a tree property browser which displays the currently selected item's properties.

All item types has a few common properties like "Position X", "Position Y" or "Position Z", but each type also adds its own type-specific properties (e.g. the text items provide "Text" and "Font" properties, and the line items provide a "Vector" property).

The source files can be found in examples/canvas_variant directory of the package.
