I've posted a tutorial about how to use Eclipse's PyDev to debug python scripts using Qt4 and QGIS.<br>I'm sorry if it's in portuguese, but my blog's main audience is my brazilian friends.<br><a href="http://mauriciodepaulo.blogspot.com/2009/12/e-viva-o-pydev.html">http://mauriciodepaulo.blogspot.com/2009/12/e-viva-o-pydev.html</a><br>
Anyway, the screenshots says everything one needs to configure it so that eclipse uses osgeo4w python and imports qgis and pyqt4.<br>I hope it helps.<br>Mauricio de Paulo<br><br>
