HTMLViewer link handling

I am using a HTMLViewer with LoadPage and passing in an imported HTML page

me.LoadPage default, Nil

Now, I want any links in the HTML to be clickable, so I follow Christian's advice from his posting to the mailing list, but make some modifications as I am not loading a webpage hosted on a server

Function CancelLoad(URL as String) As Boolean
  // http://support.realsoftware.com/listarchives/realbasic-nug/2010-02/msg00873.html - Christian Schmitz
  
  const kEventHandled = TRUE
  const kEventNotHandled = FALSE
  
  if (url = "about&#058;blank") OR (url.Left(4) = "file") OR (url.Left(2) = "C:") then  // about&#058;blank is for Mac OS X WebKit, file is for Win32 WebKit and C: is for Win32 native
    Return kEventNotHandled
  else
    ShowURL(url)
    Return kEventHandled
  end if
End Function

The first "if" line will make sure our page loads on the different OSes and with the different web browsers (sorry Linux users, I cannot seem to get the HTMLViewer to work in on my install)..

The URL parameter will contain one of the following:
"about:blank" on Mac OS X webkit
an absolute file path to the temp file, starting with "file:///" on Win32 webkit
an absolute file path to the temp file, starting with "C:\" on Win32 native renderer

Remember, this is only when you are passing in HTML source to the LoadPage.. Hopefully that makes sense and helps someone out :-)
