[yast-devel] Browser with functional links

13 Aug 2007

      Hi,

Posting this here incase anyone else hadn't thought of this before.

There are a number of exciting things that would be possible with a
web page & usable links within YaST. The registration module just
launches an external browser.

There is of course the Rich Text widget that provides a useful subset
of html, and by combining with the xdg-open utility we can have links
that open in the appropriate browser or application for the user's
desktop environment.

e.g. a link to a webpage will open in konqueror/firefox depending on
user's browser. Link to a pdf would open in kpdf on KDE, link to an
irc:// link would open in konversation/xchat etc.

Sample code:

{
	string OPEN_CMD = "xdg-open";
	    UI::OpenDialog(`opt(`centered),
			`MinHeight(22,
				`MinWidth(68,
					`VBox(
						`RichText(`id(`rtext),"")
					)
				)
			)
		);
	UI::ChangeWidget(`rtext,`Value,"<body bgcolor=\"White\">\
									<h1>Browser demo</h1>\
									<p>Example of page with functional links within YaST</p>\
									<li><a href=\"http://example.com\">This link should open in
your browser</a></li>\
									<li><a href=\"irc://irc.freenode.net/#yast\">This link should
connect you to the YaST channel</a></li>\
									<li><a
href=\"http://wiki.novell.com/images/d/d8/Quick_Reference_11_UNIX-Linux_Troubleshooting.pdf\">This
link should open in your PDF viewer</a></li>\
									</body>");
	any input =  UI::UserInput();
    while(is(input,string))
	{
		SCR::Execute(.target.bash, OPEN_CMD + " '" + (string)input + "'");
		input = UI::UserInput();
	}
}

You can do relatively complex things, for example here is a screenshot
of yaloki's irc support page running inside YaST
http://bw.uwcs.co.uk/yast-browser-qt.png .

Minor annoyances include requiring absolute paths for images.

Does anyone have any thoughts on how to do this even better, or
potential applications for this?
