+    \example quick/canvas
+    \brief This is a collection of QML Canvas examples.
+
+    This is a collection of small QML examples relating to Canvas item. Each example is
+    a small QML file emphasizing a particular element or feature.
+
+    Red heart demonstrates using a bezierCurve API to stroke and fill a red heart.
+
+    Talk bubble demonstrates using a quadraticCurveTo API to stroke and fill a customized talk bubble,
+    this example also demonstrates the fillText API.
+
+    Squircle demonstrates using a collection of simple moveTo/lineTo path APIs to draw a smooth squircle.
+
+    Rounded rectangle demonstrates using a collection if lineTo/arcTo path APIs to draw a rounded rectangle.
+
+    Smile face demonstrates using several complex path APIs to draw an fill a smile face.
+
+    Clip demonstrates using clip API to clip a given image.
+
+    Tiger demonstrates using SVG path API to draw a tiger with a collection of SVG path strings.
