Introducing the GNOME Clipboard Manager application and environment
About:
------
GNOME Clipboard Manager for GNOME 2.0 desktops is an application and an
environment for managing clipboards -a.k.a. selections- and their
available formats -a.k.a. their available targets-.
The three core components of GNOME Clipboard Manager :
* GNOME Clipboard Manager itself is a daemon that will autocollect new
clipboards and has the option to choose which clipboard is to be
pasted when an application asks for the clipboard in a specific
format. A longer list of features is listed below. They include
saving, creating, editing, merging of items. GNOME Clipboard Manager
is plugable and writing new plugins for GNOME Clipboard Manager is
not a difficult task.
* Libgcm is a library for controlling the GNOME Clipboard Manager daemon
from your own applications.
* GcmApplet is a sample GNOME 2.0 PanelApplet that uses libgcm for
controlling the GNOME Clipboard Manager daemon. It is still a little
bit buggy because I am not very good at writing PanelApplets and
because there is not very much documentation about them available
already. That is why I prefer calling it a sample.
Please check out http://gcm.sf.net/about_gcm.html if you want to know
more.

Major changes in the following areas :
Added : libgcm + a libgcmtest application
Added : Plugin subsystem + sampleplugin
Added : GcmApplet

Features list :
---------------
Note:
I know that it might be confusing but I am not the person who gave these
animals names, "a target is a format" and "a clipboard is a selection"
in the following text :
* Storing your clipboards and all their available formats. A.k.a the
collecting of clipboards.
o A clipboard (a.k.a. a selection) can have multiple formats
(a.k.a targets) o GNOME Clipboard Manager will store all your
previous clipboards and formats so that you can go back to a
previously saved clipboard o A format can be
+ Html : which are the HTML-tags of a HTML selection
when you copypaste some stuff in your browser + Image
data : If you select a portion of an image and use the
"Copy"- or "Cut"-feature in for example OpenOffice.org
+ Normal text :
a.k.a. COMPOUND_TEXT which is the most common format of
clipboards
+ Some other format used by a specific
application that contains information about the data.
For example the clipboards of OpenOffice.org contain
gzipped formats which host XML-files that define the
layout and information that is to be copypasted to for
example another OpenOffice.org screen.
o Once collected, a clipboard becomes an Item for GNOME
Clipboard Manager o Making a clipboardring by setting the
max. amount of collected items. Older items will then
automatically be deleted from the list of collected items.
o The autocollecting of new items
* Saving and loading collected clipboards (Items) to
XML-formatted files.
o The data of the items will be written to the files in
UUEncoded data to make sure that we don't write binary data in
an UTF-8 orientated fileformat like XML is o Saving multiple
items in one file is, of course, possible
* Editing and viewing some supported formats in a clipboard
o The editing of the COMPOUND_TEXT or normal text target is
possible o The editing (and previewing in a GtkHtml widget) of
the text/html target is possible
* Manipulating of formats
o Blocking specific formats that are too large to store into
memory. E.g. Blocking large binary format-types
o Copying a specified format-type to another format-type o The
possibility to write a plugin for GNOME Clipboard Manager that
does the converting of the format-data while copying it to
another format-type
* Some advanced UserInterface options
o The UserInterface is, by default, hidden. So GNOME Clipboard
Manager is, by default, a clipboard collecting daemon. You can
make it show its UserInterface by using a small external tool
or by using the GNOME Clipboard Manager Applet. o Hiding all
UserInterface objects
o Making the scrollbar follow while adding new items o
Autoselect most new collected item
o Unselect-all after collecting a new item
* Support for the following selectiontypes
o The CLIPBOARD-selection : Used when using CTRL+C and CTRL+V
and the "Copy"- and "Paste"-features in the menus of most
applications o The PRIMARY selection : The text that is
selected in your session o The SECONDARY selection : The text
that was selected the last time in your session o A CUSTOM
atom : For those who know what they are doing
* A PanelApplet
o A PanelApplet for GNOME Clipboard Manager that can make
GNOME Clipboard Manager perform some specific tasks.
* A library for your own applications to control GNOME Clipboard
Manager
o GNOME Clipboard Manager comes with libgcm which is a library
that enables your application(s) to control and make use of
GNOME Clipboard Managers features.
* The hosting of plugins
o You can write plugins for GNOME Clipboard Manager in a same
fashion as you can with applications like mediaplayers (like
xmms).

a specific feature caused very strange problems that cannot be solved.
