OpenOffice Extensions

What are extensions

Extensions in OpenOffice extends the capability of the OpenOffice program. Extension can be for OpenOffice Writer, Calc, Presentation, Database or for the core OpenOffice. For OpenOffice writer, there may be extensions that extends the dictionary feature of OpenOffice so that user can use a French dictionary. Similarly there may be extensions that adds extra grammar features. An extension for Calc might do a complex calculation like mortgage calculation or filter data in certain way. A popular extension might become part of the core program in a future release. Extensions for OpenOffice can downloaded at

How to install extensions

That extension might only appear and work on context menu. So if you cannot find it, check the extension's read-me file or manual.

Preparing development environment


Install and SDK program and SDK can be installed through package manager program, such as apt-get, yum, merge and pacman. Also, several GUI font-end for package manager programs are available to make installation easier. On Ubuntu, Synaptic is good choice. YumEx is the best option on Fedora.

  • Ubuntu:
    • With aptitude: launch a terminal and enter following command
    sudo aptitude install
    If you want SDK examples and documentations, install as well.
    sudo aptitude install
    • With Synaptic: Go to menu: System -> Administration -> Synaptic Package Manager. Search openoffice, and click,, packages, then click Mark for Installation and hit Apply on toolbar.
  • Fedora:
    • With Yum:
    sudo yum install {package name}
    To-Do: replace {package name} with real package names under Fedora
    • With YumEx:
    YumEx does not come with distribution. You needed to be installed manually.
    sudo yum install yumex
    After installation, launch YumEx, search openoffice, select those packages and install.

Note: On Fedora, sudo is not set by default. You can add you account to wheel user group so that you can use sudo. Also, you may use su to change to root, and run yum to install packages.
Note: On Ubuntu, if you use program that comes with distribution, and try to install SDK that is downloaded from website, you may encounter dependency issue. You should the SDK that come with distribution.

Install NetBean, and Extension Development Plugin

NetBean can be installed through package manager as well. Package name is netbeans. Ubuntu:

sudo aptitude install netbeans


sudo yum install netbeans

To-Do: need someone check if the packages name for Netbeans on Fedora is netbeans. After installation, you can install development plugin in NetBean. Lunch NetBean, select Plugins under Tool menu. Then switch to Available Plugins tab, and install OOo API plugin. Finally, select Options under Tool menu, and go to Miscellaneous -> OOo API Plugins tab. Fill in the path to program and SDK. Path is provide in following section.

Install Eclipse and Extension Development Plugin

To-Do: guild on install setup Eclipse for OOo Extension Dev

Path to Program and SDK

  • Ubuntu:
    • Program: /usr/lib/openoffice
    • SDK: /usr/lib/openoffice/basis3.2/sdk
    • Examples: /usr/lib/openoffice/basis3.2/sdk/example
  • Mint:
    • Program: /usr/lib/openoffice
    • SDK: /usr/lib/openoffice/basis3.1/sdk
    • Examples: /usr/lib/openoffice/basis3.1/sdk/example

To-Do: need path on Fedora and others major distros.


This is tutorial is to set up a Java development platform on Windows. You will need the following software: SDK Netbeans Make sure you install OpenOffice and the SDK before running Netbeans. First Open Netbeans and go to: Tools -> Plugins Go the Available Plugins tab and look for API Plugin and check the box beside it. It will prompt you to install and click the Install button on the bottom of the list. The plugin will install. To change the setting for the plugin go to: Tools -> Options -> Miscellaneous -> OOo API Plugin There you will see the directory path to the installation of both OO and The SDK. If you need to change it then you can make the corrections here.

Programming languages for developing an extension







.Net Resources SDK (Software Development Kit) API (Application Programming Interface) objects and methods, such as paragraphs, spreadsheets, and fonts, are accessible to Basic through the application programming interface, or API. Through the API, for example, documents can be created, opened, modified and printed. The API can be used not only by Basic, but also by other programming languages, such as Java and C++. The interface between the API and various programming languages is provided by something called Universal Network Objects (UNO).
