I have a few problems with the list/tree widgets.
Before I forget, here is the  version info

Python 2.2.2 (#1, Jan 15 2003, 01:45:57)
[GCC 3.2.1 20021207 (Red Hat Linux 8.0 3.2.1-2)] on linux2

My first problem is with creating a ListStore with
a dynamic numbers of columns.
The best thing I could come up with so far is this:
args = [gobject.TYPE_PYOBJECT] + ([gobject.TYPE_STRING] * len(titles))
model = apply( gtk.ListStore, args)
Is there a better way avoiding the use of "apply"?

Try model = gtk.ListStore(object, *([str]*len(titles)))

This uses the "*args" syntax introduced in Python 2.0.

Second, I am trying to have different background colors for different row
using the first column of of my model to hold the actual color:
for index in range(len(titles)):

           renderer = gtk.CellRendererText()
           column = gtk.TreeViewColumn(titles[index], renderer, text=index+1)
           column.add_attribute(renderer,"background-gdk",0)
           view.append_column(column)
the values for the rows including  the color rows are set here:

   def redraw_events(self):

       self._model.clear()
       for event in self._events:
           if event.get_type() == TYPE_REGULAR:
               fields = [self._color_normal]
           else:
               fields = [self._color_active]
           fields +=  self._viewer(event)
           iter = self._model.append()
           for i in range(len(fields)):
               self._model.set_value(iter, i, fields[i])
       return
When running the program I get a lot of warnings like:

GLib-GObject-WARNING **: unable to set property `background-gdk' of type
`GdkColor' from value of type `PyObject'
And, of course, my color settings are ignored. How do I work around this?
 

Make the first column type gtk.gdk.Color.  Alternatively, you can make 
the first column a string column holding the colour name, and map 
"background" to the first column, rather than "background-gdk".
