I'm using wxComboBox with my own extended search functionalities.
After catching EVT_CHAR on the TextCtrl of the ComboBox a Database search
is done - if the result is more than one row the ComboBox gets filled with the
rows from the result.
In that case I would like the ComboBox to magically pop-up just as if the user
clicked on the arrow, because if the user already is "inside" the ComboBox while
writing and pressing Enter for searching, he could continue with navigating
with the keyboard-arrow keys for example, instead of having to use the mouse again
for clicking on the ComboBox arrow.
Is there such a possibility in wxPython - i guess its at least not officially implemented,
as I didn't find much about that theme online.
See the ComboCtrl demo for wxPython 2.8 . It has a method that you can
call to pop up the listing.

The last thing I tried was:
###
nevent = wx.CommandEvent(wx.wxEVT_LEFT_DOWN)
nevent.SetId(obj.GetId())
obj.GetEventHandler().ProcessEvent(nevent)
###
"obj" being a button (for testing purposes).
Thanks in advance

No. For something like this you need to have the event be converted to the native equivalent and then sent to the native widget, and wx doesn't do that. The event handling system is only geared up to turn native events into wx events, not the other way around. To do it you'll need to call the native APIs using ctypes or something to send the right events.
Or as Josiah suggested you can use the new wx.combo.ComboCtrl to get more control over the widget.
