If the links later can become clickable, it would be good if also such
extra links in translations are handled.
I don't know how to make clickable links in an Xaw widget.
I did figure out what command to issue, though:
xdg-open http://....
does open a new tab in the default browser for the mentioned URL.
(Mentioning a local file, however, opened it in gedit, whih is indeed what
happens on my system when I double-click a .html file, but which is not
what we want.) It does require that the xdg-utils are installed, however.
I pushed a trial patch to hgm.nubati.net (master branch), which tries two
methods to invoke the xdg-open command:
One is buttons in the About Box (now redone with the generic popup):
"XBoard Home" and "What's New?". (I linked the What's New directly to the
4.6.0 page; this is after all 4.6.0...) The other is an extra menu item
"On-line User Guide". Probably we should use one system or the other
consistently, this is just to enable us to see what we like better. I would
go for the menu, I think. (Then there would also be little reason to redo
the About Box, other than that eventually I want to redo all dialogs with
GenericPopUp to limit the effort of porting to other platforms.to just
porting that single popup.)
Btw, I think an on-line user guide is quite environmentally unfriendly, as
every user is likely to use it at least once, and more likely a few dozen
times. So it would be much better to get it to him in the initial download,
where it will be zipped as well.
