Java LibreOffice Programming
Java LibreOffice Programming (JLOP) is intended for programmers who want to learn how to use the Java version of the LibreOffice API. This allows Java to control and manipulate LibreOffice's text, drawing, presentation, spreadsheet, and database applications, and a lot more (e.g. its spell checker, forms designer, and charting tools).
This book is not about how to use LibreOffice's GUI. I won't explain where to find a particular menu item to change text colour or run the spell checker. But I will explain how to do these kinds of things via API calls from Java programs. For instance, I describe a program that constructs a Word file full of randomly generated algebra questions, and show how a ASCII text file can be transformed into a slide presentation.
Although most of the examples are Java programs that call the LibreOffice API, I briefly look at other kinds of programming, such as Java macros and new LibreOffice functionality, accessible via menu items or as spreadsheet functions, and the dispatching of commands to the GUI.
One of my aims was to develop utility code to help flatten the steep learning curve for the API. For example, my Lo class simplifies the steps needed to initialize the API (by creating a connection to a LibreOffice process), to open/create a document, save it, and close down LibreOffice.
Another aim was to have my code work on LibreOffice and OpenOffice, which isn't difficult since their APIs are nearly identical. However, I must admit that at this stage I've restricted myself to testing the programs only on LibreOffice, and only on MS Windows.
