The applet works with both GTK2 and GTK3 versions of MATE and allows you to:

• Place a dock on any MATE panel, of any size, on any side of the desktop you desire.
• Pin and unpin apps to the dock. Pinned apps can be shown in the dock on all workspaces or only the workspace where they were pinned (allowing the dock to be customised for each particular workspace).
• Rearrange application icons on the dock
• Launch apps by clicking on their icons in the dock
• Minimize/unminimize running app windows by clicking the app's dock icon
• Detect changes in the current icon theme and update the dock accordingly
• Use an indicator by each app to show when it is running
• Optionally, use multiple indicators for each window an app has open
• Use different styles of indicators, or turn indicators off altogether
• Change the colour of MATE panels to the dominant colour (i.e. the most common colour) of the desktop wallpaper. The colour can be applied to all panels or just the panel containing the dock.

The applet is available in Debian testing (currently GTK2 only):

apt-get install mate-dock-applet

The applet is included by default in Ubuntu MATE 16.04. It can be used by selecting the 'Mutiny' desktop layout in the MATE Tweak application, or by simply adding it to any panel.

Note: when upgrading from Ubuntu Mate 15.10 to 16.04 any previously installed version of the applet will be replaced with the one from the distribution's respositories.

The applet is not installed by default - apt-get install mate-dock-applet will do the trick...

The applet is included in the repositories but is compiled for Gtk2, rather than Gtk3. Therefore it will not work with the version of MATE desktop supplied with Linux Mint. Currently, the only solution is to manually compile and install the applet from source - instructions are further below. Note: the latest version of the applet which will work with the version of Gtk3 used in Linux Mint is V0.80 - souce code available here.

Users of Ubuntu MATE 15.10 and earlier, or of Linux Mint 18.1 or earlier, can install the applet from the PPA kindly provided by webupd8

Note: this is currently GTK2 only

For Arch users the GTK 3 version is available as a package in the repositories.

An ebuild is available via the mate-de-gentoo

Users of other distros will need to install from source, so first install the required dependencies. Note, the package names below are for Ubuntu/Linux Mint/Debian - the name of the packages will vary on other distros.

• Python3
• Python wnck bindings (gir1.2-wnck-1.0 for Gtk2 versions of the applet, gir1.2-wnck-3.0 for Gtk3) (gnome-python2-libwnck in Fedora)
• Python implementation of Xlib - python-xlib (python3-xlib in Ubuntu based distributions and Fedora)
• GLib development files (libglib2.0-dev) (glib2-devel in Fedora)
• Python Imaging Library (python3-pil) (python3-pillow in Fedora)
• Python 3 Cairo bindings (python3-cairo)
• Bamf (bamfdaemon, libbamf and gir1.2-bamf) (bamf-daemon and bamf in Fedora)
• Python Distro (python3-distro)

then cd to the directory containing all of the development files and run:

autoreconf --install

To build a GTK2 version of the applet:

./configure --prefix=/usr

To build a GTK3 version:

./configure --prefix=/usr --with-gtk3

Then enter the following commands:

make

sudo make install

This is a little more involved. First download gir1.2-wnck-1.0 for arm architechure from here and install it with sudo dpkg -i. Then install other dependencies - sudo apt-get install git autoreconf libglib2.0-dev

From this point the instructions above for compiling from source should be followed.

In order for window minimizing and maximizing to work correctly under Compiz, the Focus Prevention Level setting must be set to off in CompizConfig Settings Manager (General Options, Focus and Raise Behaviour)
