Re: [wxperl-users] wxWidgets web browser

[Mark D. <mar...@zn...>]

After some cursory investigation, I can't actually get
Wx::InternetFSHandler to work on Win32. The obvious C code doesn't work,
and the obvious is pretty much all I can manage.

You can get pages to load if you install
Wx::Perl::FSHandler::LWP
from CPAN. Then you can do:

use Wx::FS;
use LWP::UserAgent;
use Wx::Perl::FSHandler::LWP;
my $ua = LWP::UserAgent->new;
my $handler = Wx::Perl::FSHandler::LWP->new( $ua );
Wx::FileSystem::AddHandler( $handler );
..........
$htmlwindow->LoadPage('http://www.google.com/');

However, as pointed out by Marcus, this still isn't particularly
satisfactory as it does not handle relative urls so none of the image
tags work.

You could take a look at the Wx::Perl::FSHandler::LWP code and in
particular the sub 'OpenFile'.

If you add the following code to it:

 my $path = $fs->GetPath();
 print qq(PATH = $path\n);
 print qq(LOCATION = $location\n);

you'll see where the problem lies.

This could probably by fixed by adding in your own custom handlers for
the appropriate bits of the parser and tag handlers, but if you look at
the output in wxHtmlWindow, it probably won't ever do what you require.

Thanks to the efforts of Andrew on this list putting together a patch
for Wx::ActiveX, I've  finally included Wx::ActiveX in the unicode ppms
at http://www.cava.co.uk/freetools/wxperl.html

Until Wx::WebCore is ready (which sounds wonderful) IMHO your best bet
for embedding on MSWin32 seems to be Wx::ActiveX. But I say that as one
who has read what it is supposed to do rather than from any successful
experience.
