Hi Adrian,

I'm wondering about the error message, as gConfigDict should be created by the constructor of GClientApp. gConfigDict() is defined in, which is called in line 344 of (in common/src/apps).

If I call your application, I get the error that gConfigForms is missing. This can be circumvented by adding the
following line to your constructor.

self.configurationManager.registerAlias ('gConfigForms', 'forms')

Finally you still have to setup datasources to get your app working.

Btw. which version of gnue are you using?

I am still trying (without much success) to execute a gfd form with
the ability to
specify programatically the file, the user and the password. I mean , i need to
specify them in code, not on the command line.

By instantiating the GFClient class i have been able to pass the file name
with client.ARGUMENTS.append('form.gfd').   However, passing the user
and the password in the same way proved to be impossible.

Two days ago, i have been told that it should be possible to instantiate the
GFInstance class.  And that an example of how to do that can be found in
gnue-navigator's  sources.


from gnue.forms.GFInstance import GFInstance
from gnue.forms.uidrivers import wx as ui
from gnue.forms.GFConfig import ConfigOptions
from gnue.common.apps.GClientApp import GClientApp

class gfdrunner(GClientApp):
  def __init__ (self, connections = None):
    GClientApp.__init__ (self, connections, 'forms', ConfigOptions)

  def run(self):
    instance = GFInstance(manager=self,
               ui=ui, disableSplash=1)

#     instance.addFormFromFile('/home/am/src/gfaf/gnue/prod.gfd')
#     instance.activate()

r = gfdrunner()

Traceback (most recent call last):
 File "./", line 42, in ?
 File "./", line 34, in run
   ui=ui, disableSplash=1)
 File "/usr/local/gnue/lib/python/gnue/forms/", line
153, in __init__
   options = gConfigDict()
NameError: global name 'gConfigDict' is not defined

Any ideas about how to fix this ?
