[Qgis-developer] Compiling ui files with custom widgets creates wrong imports

[Lauri Kajan]

Hi Jürgen!

I think that this can't be fixed by just setting the PYTHONPATH.

If I have understood right the problem is that PyQt and its uic module
can't find qgis_customwidgets.py or better said
'qgis-dev\python\PyQt4\uic\widget-plugins' directory because it is not told
to do so. It is not that some module can't be imported because it is not in
pythonpath. Please correct me if I'm wrong.

Directories that are searched for widget plugins by PyQt4 are defined in
uic.widgetPluginPath. I have not found any environment variable where this
list can be altered.
After I appended
"C:\OSGeo4W64\apps\qgis-dev\python\PyQt4\uic\widget-plugins" to the
widgetPluginPath list I'm able to use uic.loadUiType function inside
python. Still that doesn't solve the problem with pyuic4 because
widgetPluginPath can't be set externally.
