--------------------------------------------+-------------------------------
I've been looking at updating my app to use wxWebView in place of wxHtml.
The app makes significant use of wxMemoryFSHandler but the documentation
is a bit sparse so I hope this is a suitable solution.

I've added a very simple wxWebView file scheme handler class,
wxWebViewFSHandler to make it easier to use wxWidget's virtual file
system.

I've updated the documentation and in particular, amended the example
given with the wxMemoryFSHandler class to show how it can be used with
both the wxHtml and wxWebView systems.

The patch also adds a menu option to the WebView sample which demonstrates
how the new class is used.

Comment:

Thank you very much for this patch! I have tested it on MSW and it works
great. Just a couple of questions before I apply the patch. Firstly how
would you like to be credited in the changelog? Also have you done any
testing with file systems other than the memory handler? When I originally
wrote the wxWebViewArchiveHandler it was because the existing wxFileSystem
syntax for archive didn't work very well.

Comment:

I did consider other protocols, but after looking at the "wxFileSystem
Overview" I guessed that the way wxFileSystem implemented combined
protocols would confuse the browser engines, which is why a different
approach is needed for these. But I don't see why it shouldn't work for
any single-protocol handler. Of the 4 built-in file system handlers: 2 are
combined-protocols and the wxInternetFSHandler is a bit redundant here -
leaving only the wxMemoryFSHandler.

Maybe this should be documented, but since it was mostly guesswork, I just
left it open.

I did briefly look at converting the html/virtual sample, but it documents
a hack which is acceptable for wxHtml but probably not for wxWebView, so I
didn't pursue it.

One test I did do, which I didn't include in the sample, was to test the #
anchor part. This worked as expected.

Nick Matthews, happy to take the blame.

(In [72461]) Add generic wxFileSystem support to wxWebView using
wxWebViewFSHandler.

Closes #14623.
