"""
This is an extemely simple and crude example of using
a KHTMLPart - I put it together mostly to make sure
the openURL method worked correctly after some modifications
done in KParts::ReadOnlyPart. It took exactly four lines
added to a basic PyKDE app framework to display a URL
via the 'net:
self.w = KHTMLPart (self, "HTMLPart", self);
self.w.openURL (KURL ("http://www.kde.org"));
self.w.view ().setGeometry (30, 55, 500, 400);
self.w.show ();
(Actually 5 lines if you count the 'import' line)
You can play around with the commented out lines or add
additional code to make this do something useful. The
.rc for khtnmlpart (sorry, I never looked it up), doesn't
seem to provide much help. Also, to follow links, you
probably need to connect some signals to slots. I
haven't tried it, but this should work with a plain
KMainWindow or other widget too.
The KDE website also incorporates gifs, jpegs, and
I believe CSS too. Playing around with some other
sites, it appears the font defaults could use some
improvement.
NOTE!!! For this to work, you (obviously) need to have
a route to the internet established or specify a local
URL - PyKDE/KDE will take care of everything else.
Perceptive users will notice the KHTMLPart code is
lifted from the KDE classref.
