Because Gtk::ComboBoxText is derived from Gtk::ComboBox, I think you
can use the member function:
int get_active_row_number () const
���� Returns the index of the currently active item, or -1 if there's
no active item.

Hi,
I am porting my Qt application to Gtkmm in order to learn more about
Gtkmm.� I am not particularly clear on how to get an index into my
ComboBoxText.� So if I have a combo box of a number of text items,
in my case Irish Gaelic prepositions, how do get the index on a changed
signal?

�...
� ��� //Connect signal handler:
��� m_prepBox.signal_changed().connect( sigc::mem_fun(*this,
&IrishPrep::on_combobox_changed) );
...
All I can get from the combo box is the text selected.� In Qt I
had used a QtComboBox, where I could access the member function
currentItem.� I would rather have the actual index into it and not
the string.
Thanks in advance!
Sean
