gtk tree view. Handle both single and double click

Question

According to the GTK+3 reference site:

The "row-activated" signal is emitted when the method gtk_tree_view_row_activated() is called, when the user double clicks a treeview row with the "activate-on-single-click" property set to FALSE, or when the user single clicks a row when the "activate-on-single-click" property set to TRUE. It is also emitted when a non-editable row is selected and one of the keys: Space, Shift+Space, Return or Enter is pressed.

Is there really no way to deal with both single and double click? For example, single click does an action, double click another one.

Answer 1

You can try to use parent signals, in this case GtkWidget's signal "button-press-event", with the event of GDK_BUTTON_PRESS doing something and GDK_2BUTTON_PRESS doing other. Little note: you have grab the GtkTreeViewSelection on which row you need.

This was meant to be a comment under luciomrx answer, but is to long. In my case button-press-event didn't worked, because its handler gets fired before selection is even performed. So I simply switched to button-release-event and from there I checked for selection using gtk_tree_selection_get_selected (works only for "single" and "browse" selection modes). But in my case I wanted to show some window on double click, and simply change descriptions when user selects a row (i.e. when row gets highlighted). I think this is common scenario. And the drawback of aforementioned implementation is that user can change selection using keyboard, so my labels were left unchanged. So I used GtkTreeSelection "changed" signal instead (obtain it using gtk_tree_view_get_selection method).
