Software Development Kit %PRODUCT_RELEASE%

# Examples

The SDK provides a rich set of examples in different programming languages (Java, Python, C++, %PRODUCTNAME% %PRODUCT_RELEASE% Basic, OLE) to illustrate the use of the API and demonstrate how to benefit from the included word processor, spreadsheet, presentation software, graphics program and database of %PRODUCTNAME% %PRODUCT_RELEASE%. Some of the examples need a running office instance listening on a port. If this is necessary you will get further information in the makefiles. Every makefile contains at least one run target to execute an running example, please see the makefile output in the different example directories. Some of the examples which create a component have no run target. In these cases a document is provided which instantiates and runs the component (see the makefile output). Also the Basic examples provide documents which use and shows the implemented functionality.

UNO Component Examples | Description
Object Inspector | The Object Inspector is primarily an auxiliary tool for the developer, which can present information about an object of the %PRODUCTNAME% %PRODUCT_RELEASE% API at run-time. Depending on the object to be inspected, appropriate methods, interfaces, services, and attributes can be displayed to the developer. The methods, interfaces, services and attributes are represented in a predictable tree. If the attributes contained in an object are to be examined, the appropriate nodes in the tree can be expanded with the help of the mouse. For each non primitive object, five categories are offered to the user, as long as those are available with that object. The Object Inspector is currently available as a NetBeans project only because of major code changes. Please see the project page for further details.

%PRODUCTNAME% %PRODUCT_RELEASE% Basic examples |
The example programs are embedded in %PRODUCTNAME% %PRODUCT_RELEASE% documents in the samples directory. To view or edit the %PRODUCTNAME% %PRODUCT_RELEASE% Basic source, select the appropriate document and then select Tools->Macro. Most of the examples are stand-alone, but two of them (Creating an Index and Import/Export of ASCII Files) have an associated data file identified by a .txt file name suffix). Some of the examples are also available in Java, you can find them in the Java section.
Example | Description
Changing Appearance | To change the style used for certain words, you can start with the following example. This code searches for the regular expression `the[a-z]`, which stands for the text portion the followed by exactly one lowercase letter. All occurrences of these four letters are then changed to bold characters. The same happens in the next part of the program, this time changing the appearance of `all[a-z]` to italic. In order for this example to work, you must execute it from an open text document.
Replacing Text | If you regularly receive documents from other people for editing, you might want to make sure that certain words are always written the same. The next example illustrates this by forcing certain words to be spelled in American English. In order for this example to work, you must execute it from an open text document. For a real world application, it is a good idea to read the words from an external file.
Using Regular Expressions | Another application of automatic text modification is related to stylistic questions. Suppose your company’s policy is to avoid the use of certain words. You want to replace these words, but you cannot do that automatically because you have to find the appropriate replacement, which depends on the context. So instead of deleting or replacing the offending words automatically, you change their color to make them stand out during a subsequent manual review process. The following example handles two kinds of unwanted wordings: those which are absolutely forbidden and must be replaced by something else, and those which are considered bad style. A subroutine is responsible for the changes. It can be used to make all words in a list appear in a certain color in the text document. To keep the lists short, we use regular expressions which provide for the variants of the words (plural, adjective etc.).
Inserting Bookmarks | The next example does something very similar. This time, however, we do not change the color of the words but insert a bookmark at each of them. You can thus use the StarOffice navigator to jump directly from word to word. Bookmarks must first be created using `createInstance()`. They are then inserted with `insertTextContent()` at the current text range. The main difference to the preceding example is the For loop in `markList()`. Instead of changing the color of the current word, it creates a new bookmark, oBookmark, whose name is the current word with an integer appended. It then inserts this bookmark at the word.
Creating an Index | Indices for text documents can be created manually in %PRODUCTNAME% %PRODUCT_RELEASE% Writer by clicking on the words that should appear in the index. If the document is large, or if you have to generate indices for several documents, this task should be automated.
Adapting to Euroland | Most of the members of the European Union will abandon their old currency in favor of the new Euro in 2001. This requires modifications to all programs using the old currencies. Since the exchange rates for the old currencies have been fixed at the end of 1999, one can already convert old data. The following program does this for all values in a table that are formatted with the currency string DM.
Import/Export of ASCII Files | You can use the drawing facilities of StarOffice API to generate a picture from ASCII input. One application would be a hierarchical representation of a directory listing, based on textual data.
Stock Quotes Updater | If you want to display stock charts for certain companies, you can open up your browser every day, go to a search engine, look up the quote and copy it by hand into a table. Or you can use a program that does all this automatically. The following example relies on the sheet module. It uses URLs to obtain the current stock quotes. The quotes are displayed in sheets, one for each company. We show a line diagram and the numerical values for this company on every sheet. The functionality is hidden in the three subroutines `GetValue()`, `UpdateValue()`, and `UpdateChart()`.
Forms and Controls | The example document Burger Factory offers some forms and controls, which you can use to order your desired burger type, beverage, topping, and sauce. By hitting the button "Order now!", your order will be placed.

Object Linking and Embedding (OLE) examples |
Example | Description
ActiveX Control | The ActiveX control shows an example of access to UNO through COM technology. It requires a properly installed StarOffice version 6.0 or OpenOffice 1.0 or newer. This is a Lite ActiveX control so it can be used only in containers that allow the use of such controls. It can be activated with an <OBJECT> tag from a html-page to embed a document. Without any parameters a new writer document will be opened for editing. For more details please see the README. Note: This example works only under windows and if you don't use the MS .Net C++ compiler please check the makefile and take notice of the comments.
