Notes on Using this Reference Manual

In the descriptions of the wxWidgets classes and their member functions, note that descriptions of inherited member functions are not duplicated in derived classes unless their behaviour is different.

So in using a class such as wxScrolledWindow, be aware that wxWindow functions may be relevant.

Where not explicitly stated, size and position arguments may usually be given a value of wxDefaultSize and wxDefaultPosition, in which case wxWidgets will choose suitable values.
