Tato příručka seznamuje s programováním v jazyce Apache OpenOffice Basic. Předpokladem k pochopení popisované problematiky je určitá předchozí znalost jiného programovacího jazyka. V příručce je uvedeno velké množství příkladů , jenž by vám měly pomoci při tvorbě vašich programů v jazyce Apache OpenOffice Basic.

Tato příručka rozděluje informace o administraci Apache OpenOffice do několika kapitol. První tři kapitoly poskytují základní informace o Apache OpenOffice Basic:

• The Language of Apache OpenOffice Basic
• Runtime Library
• Introduction to the API

Tyto kapitoly poskytují základní přehled o Apache OpenOffice Basic a měl by se s nima seznámit každý, kdo chce psát programy v Apache OpenOffice Basic. Zbývající kapitoly popisují jednotlivé komponenty Apache OpenOffice API mnohem detailněji a mohou být prostudovány dle potřeby:

• Working with Documents
• Text Documents
• Spreadsheet Documents
• Drawings and Presentations
• Charts (Diagrams)
• Databases
• Dialogs
• Forms

About Apache OpenOffice Basic

The Apache OpenOffice Basic programming language has been developed especially for Apache OpenOffice and is firmly integrated in the Office package.

As the name suggests, Apache OpenOffice Basic is a programming language from the Basic family. Anyone who has previously worked with other Basic languages — in particular with Visual Basic or Visual Basic for Applications (VBA) from Microsoft — will quickly become accustomed to Apache OpenOffice Basic. Large sections of the basic constructs of Apache OpenOffice Basic are compatible with Visual Basic.

The Apache OpenOffice Basic programming language can be divided into four components:

• The language of Apache OpenOffice Basic: Defines the elementary linguistic constructs, for example, for variable declarations, loops, and functions.
• The runtime library: Provides standard functions which have no direct reference to Apache OpenOffice, for example, functions for editing numbers, strings, date values, and files.
• The Apache OpenOffice API (Application Programming Interface): Permits access to Apache OpenOffice documents and allows these to be created, saved, modified, and printed.
• The Dialog Editor: Creates personal dialog windows and provides scope for the adding of control elements and event handlers.

VBA : Compatibility between Apache OpenOffice Basic and VBA relates to the Apache OpenOffice Basic language as well as the runtime library. The Apache OpenOffice API and the Dialog Editor are not compatible with VBA (standardizing these interfaces would have made many of the concepts provided in Apache OpenOffice impossible).

Intended Users of Apache OpenOffice Basic

The scope of application for Apache OpenOffice Basic begins where the standard functions of Apache OpenOffice end. Routine tasks can therefore be automated in Apache OpenOffice Basic, links can be made to other programs — for example to a database server — and complex activities can be performed at the press of a button by using predefined scripts.

Apache OpenOffice Basic offers complete access to all Apache OpenOffice functions, supports all functions, modifies document types, and provides options for creating personal dialog windows.

Use of Apache OpenOffice Basic

Apache OpenOffice Basic can be used by any Apache OpenOffice user without any additional programs or aids. Even in the standard installation, Apache OpenOffice Basic has all the components needed to create its own Basic macros, including:

• The integrated development environment (IDE) which provides an editor for creating and testing macros.
• The interpreter, which is needed to run Apache OpenOffice Basic macros.
• The interfaces to various Apache OpenOffice applications, which allow for direct access to Office documents.

More Information

The components of the Apache OpenOffice API that are discussed in this guide were selected based on their practical benefits for the Apache OpenOffice Basic programmer. In general, only parts of the interfaces are discussed. For a more detailed picture, see the API reference.

The Developer's Guide describes the Apache OpenOffice API in more detail than this guide, but is primarily intended for Java and C++ programmers. Anyone who is already familiar with Apache OpenOffice Basic programming can find additional information in the Developer's Guide on Apache OpenOffice Basic and Apache OpenOffice programming.

Programmers who want to work directly with Java or C++ rather than Apache OpenOffice Basic should consult the Apache OpenOffice Developer's Guide instead of this guide. Apache OpenOffice programming with Java or C++ is a considerably more complex process than programming with Apache OpenOffice Basic.
