Well DocumentView is just a viewer i've done for gb.report. In fact
it's abilities is to manages different Image in a paging style layout.

So this tool is good for display Documents such as pdf or reports. But
for those documents the libs pdf and report have a .Draw method that
render the image in the given DrawingArea or image container.

For you job take a look in the gambas ide in the HelpView.class. It
inherit webview and give the hability to manage personnal url's. (in
this case "gambas://") by cheating with the error link event.

Take a look :-). Even we generate web page on the fly for the help
embedded in the code source.
