"""
|
|
|
|
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.
