Module Browser

The Browser module provides a way to display markup in your web browser. On the Windows platform, the default installed browser will be started up to display the page. On UNIX platforms, WebL tries to communicate with an already running copy of Netscape. Note that to implement this functionality, WebL has to write the markup to a temporary file in the specified character encoding.

On the Windows platform only, module Browser also provides rudimentary support for inquiring and controlling a running copy of a Netscape browser with Dynamic Data Exchange ( DDE). Specifically it is possible to detect what web page is being viewed in the browser, and to request Netscape to navigate to a specific URL. Both the support for viewing markup and the DDE functionality is bundled in a Windows platform-specific DLL called weblwin32.dll. The readme.txt file that is part of the WebL distribution contains instructions how to install this DLL on a Windows machine.
