With the same case as from the previous commit, the very long "Mounted
on ..." text is now wrapped, but the text may not be left justified.
Slowly adjust the dialog width and see how the text wrapping is updated
to fit the size adjustment but the text is centred rather than left
justified.
This is because setting the halign property to Gtk::ALIGN_START does not
guarantee left alignment of text for wrapped or ellipsized Gtk::Labels.
Use the xalign property instead.
To set the xalign property there is a method in the GtkMisc (Gtk::Misc)
base class:
gtk_misc_set_alignment (Gtk::Misc::set_alignment)
However, GtkMisc (Gtk::Misc) was deprecated in Gtk 3.14 (Gtkmm 3.14)
and in Gtk 3.16 (gtkmm 3.16) set_alignment() was replaced with the
introduction of two new methods:
gtk_label_set_xalign (Gtk::Label::set_xalign)
gtk_label_set_yalign (Gtk::Label::set_yalign)
Add a check for Gtkmm method Gtk::Label::set_xalign() in configure.ac
and use it when available.

Before Gtk 3.22 GtkScrolledWindow propagated natural size to its
Children and so on to descendants. In Gtk 3.22 this was changed to
always request the minimum size. This was done because it is believed
to be a safer default (gives a better behaviour) in case of dynamic
content inside the scrolled window, that is, content that may change
allocated size. [1][2][3]
When the scrolled window content is not dynamic the natural size is
preferable because it gives a better looking layout and without any
downside.
In the case of GParted content which is not dynamic, so request the
scrolled windows to allocate children at natural sizes for Gtk >= 3.22.
The benefits of natural size allocation are evident in presence of
wrapping labels (for example inside the "Partition Info" dialog), that
with the minimum size request likely end up taking a very small width.

Closes!22 - Increase minimums to libparted 2.2 and glibmm 2.32
gdk_spawn_command_line_on_screen() is not present in Gtk3. The
documentation from Gtkmm 2.24 states [1]:
gdk_spawn_command_line_on_screen has been deprecated since version
2.24 and should not be used in newly-written code. This function is
being removed in 3.0. Use either g_spawn_command_line_sync(),
g_spawn_command_line_async() or GdkAppLaunchContext instead.
g_spawn_command_line_sync() and g_spawn_command_line_async() are screen
/ display agnostic, as such we would loose functionality. There is a
workaround, which involves setting the DISPLAY environment variable [2],
but it's a weak solution (and I don't know if it works on backends
other than X11).
GdkAppLaunchContext is an implementation of GIO's GAppLaunchContext that
handles launching an application in a graphical context [3]. Therefore
use GdkAppLaunchContext and GIO's GAppInfo.
GdkAppLaunchContext was introduced in Gtk2 version 2.14. The C++
wrapper Gdk::AppLaunchContext was introduced only in Gtkmm3 version 3.4
[4]. Bump the minimum required version of Gtkmm to 3.4.0 for this
requirement.
GAppInfo was introduced in GLib version 2.16. The C++ wrapper
Gio::AppInfo was introduced in Giomm version 2.16. Note that the
minimum required version for glibmm is already 2.32.

Use of Glib::thread_init() was deprecated in glibmm 2.32 [1]. The
oldest supported distributions have these versions:
Debian 8 glibmm 2.42.0
RHEL / CentOS 7 glibmm 2.56.0
SLES 12 glibmm 2.38.1
Ubuntu 14.04 LTS glibmm 2.39.93
Checking further the glibmm 2.32 reference manual says this about
Glib::thread_init() [2]:
Initializes the GLib thread system.
Deprecated:
Calling thread_init() is no longer necessary and no longer has any
effect.
However only some of the glibmm example programs had Glib::thread_init()
removed, others had it replaced by Glib::init() [3]. Again the glibmm
2.32 reference manual says this about Glib::init() [4]:
Initialize glibmm.
You may call this more than once. You do not need to call this if
you are using Glib::MainLoop or Gtk::Main, because they call it for
you.
GParted does call Gtk::Main and test_PipeCapture does call
Glib::MainLoop. Therefore just raise the minimum version to glibmm 2.32
and remove both calls to Glib::thread_init().

Scrollkeeper and the associated OMF catalog files are used by the
GNOME 2 version of yelp to display the GParted help manual. To see how
this works try the following command:
yelp ghelp:gparted
GNOME version 3 and higher yelp do not require scrollkeeper or the OMF
catalog files to properly display the GParted help manual. And in fact
GNOME 3 deprecated the GNOME 2 method of building and installing GNOME
help documents altogether; including use of GNOME_DOC_INIT autoconf
macro, the gnome-doc-utils package and use of scrollkeeper.

This is needed to build GParted documentation on still supported GNOME 2
distributions RHEL / CentOS 6. So avoid requiring deprecated
scrollkeeper on GNOME 3 by automatically disabling scrollkeeper database
updates when the scrollkeeper-update command is not available.

--------------------+------------------------+-------------------

Yes | --disable-scrollkeeper | No
| |
No | <any> | No
Note that because GParted is still using the GNOME 2 documentation build
system it still builds and installs OMF files. It is just that they are
not required with GNOME 3 yelp and this commit automatically disables
updating the scrollkeeper database when the scrollkeeper-update command
is not available.
Bug 743318 - configure script missing check for scrollkeeper dependency
GParted fails to display when run under Wayland [1][2][3]. This is
because by intentional design Wayland doesn't allow applications with
root privileges access to the display [4].
As an interim workaround make the gparted shell wrapper use xhost to
grant root access to the X11 server if root doesn't already have access,
but only when configured. Granting root access must be explicitly
enabled when building GParted like this:
./configure --enable-xhost-root
It defaults to disabled. When gpartedbin binary ends the shell wrapper
revokes root access only if it granted such access.

DISPLAY=:0.0
$ sh -x /usr/local/bin/gparted
...
+ pkexec /usr/local/bin/gparted

variable to allow execution of X11 applications until the introduction

Only install the GParted polkit action file when pkexec is being used as

Bug 776437 - GParted fails to run as root under Wayland
An action file is always needed with polkit to describe the privileged
actions that are available to the subject (client program). For GParted
the only available action is to run the gparted shell script as root.
Note that the polkit action file will be installed into location
$(prefix)/share/polkit-1/actions. This is required by the GNU Coding
Standards [1] and to prevent 'make distcheck' from failing [2]. However
polkit only uses /usr/share/polkit-1/actions for it's action files [3].
This dilemma was discussed in this Bugzilla bug 776437 and on the
general Automake discussion email list [4]. The solution is to simply
document in the README file that a manual additional installation step
may be required.
The action file is marked as translatable with the underscore (_) of the
_description and _message tags identifying the string to be translated.
Use of INTLTOOL_POLICY_RULE in Makefile.am to merge translations into
the polkit action file necessitates increasing the minimum version of
intltool to 0.36.0 where it was first introduced in intltool.m4. This
will prevent GParted building on RedHat/CentOS 5 which only has intltool
0.35.0. But that doesn't matter because RedHat/CentOS 5 reached end of
life on 31st March 2017.

Bug 776437 - GParted fails to run as root under Wayland
Many of the distributions (confirmed for Arch Linux, Debian, Fedora,
OpenSUSE, RedHat/CentOS and Ubuntu but likely many others too) are now
using polkit as the mechanism to authorise privileged actions, including
using it to authorise GParted to run as root in their packages of
GParted. Therefore make the GParted configure script check for the
pkexec command.
Use pkexec with the --disable-internal-agent option when available,
preventing pkexec using it's own textual authentication agent. When
running GParted from a desktop icon or menu there is no terminal with
which to interact with the textual authentication agent to it can't be
used. The desktop's graphical agent must be running. This matches how
some distributions already use polkit in their own packages of GParted.
Required actions file will be added in the next commit.

Previously the autoconf check for Gtk::Window::set_default_icon_name()
method was a compile test because the documentation reported the method
was available in gtkmm from 2.6 [1], however it wasn't available on
RHEL / CentOS 5.x with gtkmm 2.10.
Then commit [2] added detection and enabling of C++11 compilation, but
after the above autoconf check. So on Fedora 23 the compiler based
autoconf check for set_default_icon_name() method failed because C++11
compilation had not yet been enabled:

> checking whether g++ supports C++11 features by default... no
> checking whether g++ supports C++11 features with -std=gnu++11... yes
The gtkmm source code reveals that set_default_icon_name() method was
