Bug#824606: libgtk-3-0: Single click opening of selected items in file-selector is confusing

[Javier Ayres]

Package: libgtk-3-0
Version: 3.20.4-1
Severity: normal

Hi, this bug is a copy of
https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1519778. I'm copying the
content of the Ubuntu bug below.

> Since the GNOME 3.18 upgrade I keep opening files by error in the gedit file-
selector. It took me a while to understand, what's going on why sometime single
click acts like double > click it seems to be due to this change
> https://git.gnome.org/browse/gtk%2B/commit/?id=fb0a13b7
>
> "file chooser: Allow activating without double-click
> Interpret a unmodified primary click on the selection like a double
> click. This makes it possible to activate a file or open a folder
> without using double-click."
>
> That has several issues:
>
> - the behaviour seems inconsistant, it's not easy to understand what's going
on as an user (I first though my mouse buttons was having issues)
>
> - if you double click on a selected directory to browse it, it opens it with
the first click then open an item directly in the directory, which is not what
you want (seems https://> bugzilla.gnome.org/show_bug.cgi?id=757950 was meant
to address that but it doesn't here)
>
> - if you select an item, switch to another windows and click back on the
file-selector to focus it and manage to hit the selected item then it's
opened...
>
> I'm unsure what the issue the change was trying to address, if that's about
touch devices maybe the behaviour shouldn't impact pointer devices?
