[pygtk] two treeview problems

[N. Volbers]

Hello everyone on the list,

I have two questions regarding the treeview widget:

(1) (see attached sample script) Using a CellRendererCombo it is 
possible to manipulate the model data by choosing a value from the 
combo. Clicking on 'apply' in the sample script will dump the values in 
the model to stdout. My problem occurs, if you try to modify a value by 
selecting a value in the combo, and then you immediately click on apply 
without leaving the combo. In this case the 'edited' signal of the 
treeview is not emitted and the selected value in the combo is not set 
in the model! However, at least for myself I would prefer this kind of 
behaviour. Is there any way to force the treeview to finish any pending 
edit operations?

(2) For some columns, I would like to have a button appear if you enter 
the row, e.g. a little button with three dots indicating that if you 
click on the button you will get a fancy dialog. I guess it would be 
possible to write such a thing using a GenericCellRenderer, but I would 
be very happy if anybody could point out existing code to me?

With best regards,

Niklas Volbers.
