# # pyParts.py (C) 2002 Jim Bublitz # """ This is an extemely simple and crude example of using a TDEHTMLPart - 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 PyTDE app framework to display a URL via the 'net: self.w = TDEHTMLPart (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 TDEMainWindow or other widget too. The TDE 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 - PyTDE/TDE will take care of everything else. Perceptive users will notice the TDEHTMLPart code is lifted from the TDE classref.
