As you already know, calling TreeView::set_activate_on_single_click(
false ) and connecting to TreeView::signal_row_activated() allows you to
intercept a double click. To intercept a single click, get the
TreeSelection object associated with the TreeView using
TreeView::get_selection() and connect to
TreeSelection::signal_changed(). Be aware that a single click on a row
that's already selected will not emit signal_changed(). Also, there's a
warning somewhere in the documentation that says you may occasionally
receive signal_changed() when in fact there has NOT been a change in the
selection.
If that doesn't do what you need, you can also intercept and handle
clicks at a much more basic level with
TreeView::signal_button_press_event(). There's an example at
https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/treeview/popup
that will get you started in that direction.

Hi
I am working on a software that has been developed using gtkmm 2. I
have been working on a treeview. I wish to implement two different
actions on single and double click on rows of this treeview.
The property "activate-on-single-click" is available in gtkmm 3. Else
this property could have been used for both type of clicks.
signal_row_activated() is emitted when the user double clicks a
treeview row.
How can I achieve both type of clicks for the treeview?
