Here we present an example in detail. The class CardLayout is inspired by the Java layout manager of the same name. It lays out the items (widgets or nested layouts) on top of each other, each item offset by -TQLayout::spacing(). +TQLayout::spacing().

To write your own layout class, you must define the following:

 In this case, we choose a simple implementation: we store an integer

 constructor. In our example we do not need a destructor.

 several child widgets, because it will have to do a complete layout
 every time. Instead, calculate the geometry and then set it. (This
