wxWidgets Discussion Forum

Since streams in wxWidgets seems to be similar to the ones from Java, I was wondering how to make a custom own stream class, like for example DESInputStream, that should decrypt DES data from some wxInputStream. Is there some examples how to do something like that?

Usually these stream classes derive from wxFilterInputStream and take a wxInputStream as input parameter.

One example would be wxZlibInputStream, its implementation is relatively small and can be seen in <wxdir>/src/common/zstream.cpp

OK, so it seems to be really similar to how it´s done in Java. Howewer in Java I have to overwrite read, posiblly some other functions, not shure since it long time ago, but do I have to overwrite some functions to create a custom wxWidgets stream? I gues I have to owerwrite read, but which one?
