Note: The first three chapters introduce you to LibreOffice Basic: These chapters provide an overview of LibreOffice Basic and should be read by anyone who intends to write LibreOffice Basic programs. It marks a certain point within a text document and can be navigated in various directions through the use of commands. You do, however, have the option of switching to a TextCursor which allows for navigation at the level of characters, sentences and words. This object is then applied to the required text area in order to perform the action. The com.sun.star.awt.UnoControlEdit service forms the basis for text fields. VBA: LibreOffice Basic does not support the VBA Like comparison operator. In the following example, variable I is the loop counter, with an initial value of 1. The type declaration symbol for a single variable is !. In its simplest form, the command for an explicit declaration of a variable is as follows: This example declares a variable with the name MyVar and the type variant. Furthermore, the following methods are provided through the view object of the list box: LibreOffice forms can be directly linked to a database. The InputBox function queries simple strings from the user. In this instance, access is provided directly through the HeaderText property of the page style rather than the HeaderFooterContent object. The following properties are provided for pie and donut charts with the Diagram object: LibreOffice has an integrated database interface (independent of any systems) called Star Database Connectivity (SDBC). The options for defining color gradients and hatches let you create other colors into play. The methods are accessed through the following object call: A format is specified using a format string that is structured in a similar way to the format function of LibreOffice Basic. This function is similar to the one that is used in text documents as described in #Text Documents. Note: The corresponding constant for SearchFlags is: The following example shows how the content of an opened window can be replaced with the help of the frame parameter and SearchFlags: The example first opens the test.odt file in a new window with the frame name of MyFrame. Even in the standard installation, LibreOffice Basic has all the components needed to create its own Basic macros, including: The components of the LibreOffice API that are discussed in this guide were selected based on their practical benefits for the LibreOffice Basic programmer. The Step-value of 0 is a special case. The properties are accessed by means of cascading expressions (for example, Range.Font.AllCaps). The 0 to 127 ASCII codes correspond to the alphabet and to common symbols (such as periods, parentheses, and commas), as well as some special screen and printer control codes. Queries are used to simplify working with databases because they can be opened with a simple mouse click and also provide users without any knowledge of SQL with the option of issuing SQL commands. Since replacing parts of character sequences is one of the most frequently used functions, the Mid function in LibreOffice Basic has been extended so that this task is performed automatically. Example 1: access by means of the number (numbering begins with 0), Note: Webworld record scup nando's long stem broccoli recipe charles dierkop boxer mariana mazza conjoint rumeur which of the following statement is false about culture smith river oregon striper fishing jonathan creek the seer of the sands film location docker hughes death Charts are not treated as independent documents in LibreOffice, but as objects that are embedded in an existing document. The actual object form can be accessed through the Forms list at the drawing level. It provides the functions for the frame object of LibreOffice, under which all document windows are classified. The model object of a checkbox form provides the following properties: The model objects of text field forms offer the following properties: The model object of the list box forms provides the following properties: Note: For an understanding of the API, it is, however, useful to have the assignment of methods to various interfaces handy, since many interfaces are used in the different services. VBA: The flags used in VBA for querying the concealed, system file,archived and volume name file properties are not supported in LibreOffice Basic because these are Windows-specific and are not or are only partially available on other operating systems. Through these, you then have access to the subordinate objects. The Form Functions Toolbar is used for editing forms. There is no direct counterpart in LibreOffice Basic for the Characters, Sentences and Words lists provided in VBA. In the simplest scenario, these are the X and Y-axes. It accesses the array of models using the GetGroupByName method (rather than the GetByName method to determine simple models). Programmers of other languages such as Java, C++, or Delphi should also find it easy to familiarize themselves with LibreOffice Basic. The form can be defined using two properties. Whereas the document object in VBA is called a Workbook and its individual pages Worksheets, they are called SpreadsheetDocument and Sheet in LibreOffice Basic. You can, for example, highlight a certain word within a text using bold type or center a line. The following example shows how a text file is opened, written, and closed: Text files are read in the same way that they are written. These are presented in detail in the #Introduction to the LibreOffice API. A database is incorporated into LibreOffice by creating what is commonly referred to as a data source. They can, however, only be used in tables that do not contain merged table cells. therefore ensures that the text is preceded by a tab character (Unicode-value 9) and that a hard line break (Unicode-value 13) is added after the text. The wall is set to be blue. The descriptor objects are created using the document object, completed in accordance with the relevant requests, and then transferred back to the document object as parameters for the search methods. StarOffice 5: The Value, String, and Formula properties supersede the old PutCell method of StarOffice 5 for setting the values of a table cell. There are no practical limits on the indexes or on the number of elements in an array, so long as there is enough memory: Note: All directories needed within a hierarchy are also created, if required. This guide provides an introduction to programming with LibreOffice Basic. The True value of the IsDate property results in only the date and not time being displayed. The following example is an algorithm that uses two loops to sort a list by names. Note: For example, the TextCursor in the following example. LibreOffice Basic saves strings as string variables in Unicode. The program code then uses the Doc.createInstance call to create the rectangle drawing object as specified by the com.sun.star.drawing.RectangleShape service. Remember to use the object returned from opening the document instead of ThisComponent. Whereas VBA uses the Document.Frames.Add method for this purpose, creation in LibreOffice Basic is performed using the previous procedure with the aid of a TextCursor as well as the createInstance method of the document object. This can be compared with highlighting a point in the text using the mouse. If a ResultSet is a SCROLL_INSENSITIVE or SCROLL_SENSITIVE type, it supports a whole range of methods for navigation in the stock of data. Unlike C++ or Delphi, the LibreOffice Basic compiler does not create executable or self-extracting files that are capable of running automatically. The following example shows how a bookmark can be found within a text, and a text inserted at its position. In other words, formatting using templates is assigned a lower priority than direct formatting in a text. Checkboxes provide the following properties: The model object of a checkbox provides the following properties: The following example shows some of the properties for the checkboxes: These buttons are generally used in groups and allow you to select from one of several options. These include. Once the method has been completed, Save saves a return value in the Ok variable. In the hexadecimal system, the numbers 0 to 9 and the letters A to F are used as numbers. For a detailed description please refer to the LibreOffice Basic Guide which is available separately. This section describes the Integrated Development Environment for LibreOffice Basic. This section describes how to assign Basic programs to program events. The example checks all drawing elements to determine whether they support the com.sun.star.drawing.XControlShape interface needed for control element forms. Throughout this document, the LibreOffice installation directory is represented in syntax as install-dir. The variable Rect determines the position and size of the chart within the first sheet in the spreadsheet document. You will find details about this in the LibreOffice Developer's Guide. As Basic makes automatic type conversions, there is usually no problems using a constant in an expression. In this example, the getByName method is used to find the bookmark required by means of its name. A complete If statement may be written on a single line, with a simpler syntax. The number of additional, deleted and modified characters for these expressions can be defined individually. The majority of these properties are defined in the com.sun.star.text.BaseFrameProperties service, which is also supported by each TextFrame service. Function calls, mathematical expressions, and other linguistic elements, such as function and loop headers, must be completed on the same line that they begin on. Instead, the DoLoop is executed until a certain condition is met. The com.sun.star.style.PageProperties service defines the following properties of a pages background: The page format is defined using the following properties of the com.sun.star.style.PageProperties service: The following example sets the page size of the "Default" page style to the DIN A5 landscape format (height 14.8 cm, width 21 cm): The com.sun.star.style.PageProperties service provides the following properties for adjusting page margins as well as borders and shadows: The following example sets the left and right-hand borders of the "Default" page style to 1 centimeter. Templates are auxiliary documents. Functions and procedures can receive one or more parameters. Programmers who want to work directly with Java or C++ rather than LibreOffice Basic should consult the LibreOffice Developer's Guide instead of this guide. The following example outlines the replacement process within a drawing: This code uses the first page of the document to create a ReplaceDescriptor and then applies this descriptor in a loop to all the pages in the drawing document. There are numerous options for formatting cells, such as specifying the font type and size for text. If you want to display the layout on screen, then you should create the associated LibreOffice Basic procedures so that they can be called up by the event handlers. The com.sun.star.view.XPrintable interface, which contains the methods for printing documents. Since LibreOffice Basic is a procedural programming language, several linguistic constructs have had to be added to it which enable the use of UNO. WaitUntil takes a parameter of type Date, with a combined date and time value. Data can either be displayed as 2D or 3D graphics, and the appearance of the chart elements can be individually adapted in a way similar to the process used for drawing elements. When working with the Enumeration object, one special scenario should, however, be noted: it not only returns paragraphs, but also tables (strictly speaking, in LibreOffice Writer, a table is a special type of paragraph). LibreOffice Basic provides a whole range of methods for reading and writing files. An array declaration is similar to that of a simple variable declaration. This status arises, for example, when querying the bold type property of a paragraph, which includes both words depicted in bold and words depicted in normal font. The user can therefore, for example, change the font type of all level one headers by means of a central modification in the document. If you want to keep the original values, use the Preserve command: When you use Preserve, ensure that the number of dimensions and the type of variables remain the same. For example, you can define an array to contain all the words in a text that begin with the letter A. Spreadsheet documents, like text documents, provide a function for searching and replacing. ThisComponent returns the last previously active document. The complete name in the named example would be: In addition to the module and service terms, UNO introduces the term 'interface'. If a dialog contains an OK or a Cancel button, the dialog is automatically closed when you click one of these buttons. The five most important placeholders within a template are the zero (0), pound sign (#), period (. If the cursor of LibreOffice is in a cell, then the name of that cell can be seen in the status bar. The example shows a loop that runs through all sheet elements one after another and saves a reference to each in the Sheet object variable. As the number of these words is initially unknown, you need to be able to subsequently change the field limits. To make an instance of the type actual variables that can be read and stored use the Dim as New statement: As shown in the example below, the Type definition may be written at the start of a module (before the first Sub or Function). The following methods are provided as presentation objects: The following properties are also available: LibreOffice can display data as a chart, which creates graphical representations of numerical data in the form of bars, pie charts, lines or other elements. The dispose method at the end of the code releases the resources used by the dialog once the program ends. LibreOffice provides various ways of establishing database connections. Again, the second parameter specifies the number of columns that you want to delete. Finally, the removeByName call removes the object behind OldStyle from ParagraphStyles. They work in all applications of LibreOffice and help to significantly simplify formatting. If the field proves to be a date/time field or an annotation, then the corresponding field type is displayed in an information box. When administering strings, LibreOffice Basic uses the set of Unicode characters. Alternatively, you can change the start index for all data field declarations to the value 1 by using the call: The call must be included in the header of a module if you want it to apply to all array declarations in the module. features than the dialogs for the other three languages. As a result, it returns a data field containing the names. Changes made to the variables are retained when the procedure or function is exited: In this example, the value A that is defined in the Test function is passed as a parameter to the ChangeValue function. The found expressions differ by up to two letters from the search expression: Note: This includes the distance of the paragraph from the edge of the page as well as line spacing. The text in the paragraph can be retrieved and modified using the String property: The example opens the current text document and passes through it with the help of the Enumeration object.
