""" This custom XRCED launcher allows a small wx function to be wrapped
so it provides a little extra needed functionality.

XRC sometimes need to check if a node contains a filename. It does so by
checking node types. This works fine, until we start working with custom
controls, of which XRC knows nothing by default.

The little wrapper added to the pywxrc.XmlResourceCompiler.NodeContainsFilename
method,  will return true if it contains a value ending with '.png', indicating
the content is an PNG image.
