This tutorial is meant to be a basic guide; it tries to assume only a no prior knowledge of wxWidgets API; for a detailed API description you need to refer to the wxWidgets/wxPerl manual (downloadable copy). The key thing you need to keep in mind while browsing wxWidgets documentation is that, if a wxPerl class is called, say, Wx::Frame, you should search for wxFrame in wxWidgets documentation.

A reasonably good Perl knowledge is required. You need to understand basic Perl syntax, the creation and use of modules, and how objects work in Perl.
