[Glade-users] making comboBox open up the dropdown list

[ashats at hotmail.com (Arthur Shats)]

I created a comboBox in Glade. 
When I tab into the box, I want the list of items that comboBox has to dropdown automatically, like an 
equivalent of clicking on the box's arrow.
How would I do this in Python?
 
Also, in one of my fields I have _activate handler to catch the Enter key. When Enter is pressed I would like 
to set focus to comboBox and open the dropdown list without clicking on the arrow. Doing myBox.grab_focus() 
will just highlight the comboBox, but I also need to for the box's list to drop down. Any suggestions? 
Examples would be helpful.
 
Thanks,
Arthur.
