|
<p>This example demonstrates how to use the <a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a> 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 <a href="http://qt.nokia.com/doc/4.6/qvariant.html">QVariant</a>.</p>
|
|
<p align="center"><img src="images/canvas_variant.png" /></p><p>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.</p>
|
|
<p>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).</p>
|
|
<p>The source files can be found in examples/canvas_variant directory of the package.</p>
