r952 | In addition to the obvious value and label properties the user can also control | ||
the visual appearance of a slice. By modifying the visual appearance also means that | ||||

To enable user interaction with the pie some basic signals are provided about clicking and hovering. | ||||

\qmlclass PieSlice QPieSlice | ||||
PieSlice defines the properties of a single slice in a PieSeries. The element should be used | ||||
as a child for a PieSeries. For example: | ||||
\snippet ../examples/qmlpiechart/qml/qmlpiechart/main.qml 2 | ||||
An alternative (dynamic) method for adding slices to a PieSeries is using PieSeries.append | ||||
method. | ||||
\snippet ../examples/qmlpiechart/qml/qmlpiechart/main.qml 4 | ||||
In that case you may want to use PieSeries.at or PieSeries.find to access the properties of | ||||
an individual PieSlice instance. | ||||
\snippet ../examples/qmlpiechart/qml/qmlpiechart/main.qml 5 | ||||
