Complete with downloadable source code examples, lots of source example in the article, and plenty of prose to keep you awake, AntonyPranata.com brings us an article on how to create customizations using subclassing with a list box. Add some spice and uniqueness to your apps.
This article explains how to subclass a list box in Symbian, especially in UIQ. One reason to subclass a list box is to have our own custom list box, for example you can display a double line list box (see Figure 1a). I will focus the discussion in this article on UIQ because Series 60 has already various types of list box, for instance CAknDoubleStyleListBox, CAknSingleHeadingStyleListBox, etc. In most cases, you can use one of these classes. However, in a few cases, you might need to subclass list box in Series 60 as well.
