WxBrowser - a wxPerl HTML Browser

Category:

GUI Programming

Description:

A crude HTML Browser written using wxPerl. More of a minimalistic demo than anything. Nice layout IMO (a hint of things to come).

If you want the GOBAR at the bottom, just ## switch these two lines, the wxBOTTOM or wxTOP don't matter
$sizer1->Add( $sizer3, 0, wxGROW|wxTOP, 0 );
$sizer1->Add( $sizer2, 1, wxGROW|wxALIGN_CENTER_VERTICAL, 0 );

WxBrowser is a crude browser created as a demo of wxPerl
Has basic support for html (probably html 1.0 or 2.0)
That means, no cookies, no images, no forms, bad tables ;)

This is excelent. Thanks you for posting. Will be an awesome foundation for a full featured perl web browser I intend to write. Cant believe it took me so long to find it. ^_^ Cheers, Kyle.
