Sets the current keyboard focus to be at path, and selects it.
This is useful when you want to focus the user’s attention on a particular row. If focus_column is not
null, then focus is given to the column specified by it. Additionally, if focus_column is
specified, and start_editing is true, then editing should be started in the specified cell.
This function is often followed by gtk_widget_grab_focus (this) in order to give keyboard
focus to the widget. Please note that editing can only happen when the widget is realized.
If path is invalid for model, the current cursor (if any) will be unset and the function will return without
failing.
