Hi,

I'm using PyKDE4, and trying to load Designer .ui files. I have a problem with one \
file which has the following KUrl widget:

    <widget class="KUrlRequester" name="kcfg_executable">
     <property name="mode">
      <set>KFile::ExistingOnly|KFile::File</set>
     </property>
    </widget>

When I try to load this using the uic module, I get the following error:

Traceback (most recent call last):
  File "./kterminal_example.py", line 43, in create
    self.creator = ExecutableEditor()
  File "./kterminal_example.py", line 21, in __init__
    self.ui = uic.loadUi("Projects/exekutor/src/ExecutableEditor.ui")

    self.wprops.setProperties(obj, branch)
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 403, in \
setProperties  prop_value = self.convert(prop, widget)
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 368, in convert
    return func(prop[0], **args)
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 113, in _set
    expr = [self._pyEnumMember(v) for v in prop.text.split('|')]
  File "/usr/lib/pymodules/python2.7/PyQt4/uic/properties.py", line 108, in \
_pyEnumMember  raise AttributeError("unknown enum %s" % cpp_name)
AttributeError: unknown enum KFile::ExistingOnly

I have checked that importing KFile (from PyKDE4.kio) in the main program makes no \
difference, and that importing it from the interpreter  prompt allows me to print the \
value of KFile.ExistingOnly. So I guess from this last line that the issue is that \
the uic module somehow  needs to know how to resolve the KFile name. Any ideas on how \
to resolve this issue would be appreciated.

Thanks, Shaheed
