Cascades Development

[dridk]

From Qt, it was easy to custom a QML element by reimplement the paintEvent() and use a QPainter. 

Is there a way from Cascade to custom a QML element ? For example, create PieChart Element as the document show above :

Cascades does all its rendering in a seperate thread and does not expose any API for custom rendering/painting.

There are two workarounds for this:

1. Using the ForeignWindow class, it is possible to embed a window in the Cascades scene. Therefore you could create your own window and paint your window in any way you like - OpenGL or using QPainter on a QImage, with the QImage being backed by the actual window buffer.
2. Paint to a QImage and use that as a source for a PaintDefinition inside an ImageView
