[PyKDE] PyQt Tutorial: How to write reusable widgets (and a bug report)

[Roberto Alsina]

I just finished writing a short tutorial that explains how to write custom
widgets in PyQt that are easy to reuse on other applications. Hope you
like it!

It does however, also work as test case for something that is (IMHO) a
bug, but may be very hard to fix.

If you define a custom widget for designer and implement it using PyQt,
any connection defined in designer to a slot in the python-based widget is
compiled by pyuic into this:

self.connect(self.pushButton1,SIGNAL("clicked()"),self.restEditor1,SLOT("render()"))

While it should be something like this:

self.connect(self.pushButton1,SIGNAL("clicked()"),self.restEditor1.render)

I don't think this is fixable because pyuic can't guess that
self.restEditor1 is python-based, but I hope the PyQt guys can surprise me
with a patch :-)

It's not terribly important, because you can use it just fine, you only
need to handle the connections on python-code, but it is a small problem.
