=begin
This is a ruby version of Jim Bublitz's pykde program, translated by Richard Dale
=end
#
# pyParts.py (C) 2002 Jim Bublitz <jbublitz@nwinternet.com>
#
=begin
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 Korundum app framework to display a URL
via the 'net:
w = KDE::HTMLPart.new(self, "HTMLPart", self)
w.openURL(KDE::URL.new("http://www.kde.org"))
w.view().setGeometry(30, 55, 500, 400)
w.show()
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.
