Before we discuss anchors, let's talk about property groups in general. This is a new concept introduced in QML. Property groups are used when there are multiple properties with a similar purpose. For example, the Label type has a number of properties related to the font. They can be implemented as separate properties; consider the following example:
Label { // this code does not work fontFamily: "Helvetica" fontSize: 12 fontItalic: true }
However, such repetitive code is hard to read. Luckily, font properties are implemented as a property group, so you can set them using the group notation syntax:
Label { font { family: "Helvetica" pointSize: 12 italic: true }}
This code is much cleaner! Note that there is no colon character ...
