In this code, we place a (vertical) box with two rectangles as child elements.

It has a command line interface with which to act on those rectangles\textquotesingle{} {\bfseries{size hints}}\+:

\end{DoxyCodeInclude}
 That should be self explanatory. Change those values (possibly resizing the box, which will resize together with the example\textquotesingle{}s window) to get how size hints are honored by a container object, which in this case is the Evas box.
