The example first creates a text field which supports the com.sun.star.text.textfield.PageNumber service. XIndexAccess provides the methods for accessing individual objects. As Basic makes automatic type conversions, there is usually no problems using a constant in an expression. its spell checker, forms designer, and charting tools). If a number is not provided, 0 is displayed in its place. For example, if only the C:\SubDir1 directory exists, then a call. The Step property of a dialog defines the current tab page of the dialog whereas the Step property for a control element specifies the tab page where the control element is to be displayed. It is important that the name and position of a cell are not confused because row counting for names begins with 1 but the counting for position begins with 0. The following example creates a table with the help of the createInstance method described previously. The example creates a text frame, inserts this in the current document and opens a TextCursor for the text frame. Page properties are the formatting options that position document content on a page as well as visual elements that are repeated page after page. 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. Alternatively, if only an empty document without any adaptation is needed, a private:factory URL can be specified: The call creates an empty LibreOffice writer document. This view shows not only the individual values, but also an overview of all the values. The return value can be overwritten several times within the function. Note: The example uses the supportsService method to check whether the TextElement is a paragraph or a table. The ResultSet object provides Update methods for modifying values, which are structured in the same way as the get methods for retrieving values. Paragraphs provide their own Enumeration object for this purpose. = 1. VBA: A ResultSet containing the READ_ONLY and SCROLL_INSENSITIVE properties corresponds to a record set of the Snapshot type in ADO and DAO. The second parameter of Dir specifies whether files or directories are to be searched for. You specify the qualifiers in the With statement. If a dialog contains an OK or a Cancel button, the dialog is automatically closed when you click one of these buttons. In the second example, the sheet is accessed by its name and the getByName method. If this procedure was created in LibreOffice Basic, you can assign it to an event required using the property window of the dialog editor. In addition to this guide, you can get more information about objects from the following sources: the supportsService method, the debug methods as well as the Developer's Guide, and the API reference. The command: specifies a delay of 2 seconds (2000 milliseconds). In the simplest scenario, these are the X and Y-axes. These are presented in detail in the #Introduction to the LibreOffice API. The grouping of control elements in LibreOffice Basic is only used to ensure a visual division by drawing a frame around the control elements. The database interface from LibreOffice is available in the LibreOffice Writer and LibreOffice Calc applications, as well as in the database forms. LibreOffice Basic returns the name of the first directory entry found. Establishing whether a section of a document has been directly or indirectly formatted is not easy. LibreOffice positions the control elements of a form at drawing object level. VBA: The CellProperties object in the LibreOffice API is comparable with the Interior object from VBA which also defines cell-specific properties. If it finds the search term, it takes the part before the expression and writes it to the Result return buffer. The properties are accessed by means of cascading expressions (for example, Range.Font.AllCaps). The main properties of this service are described in the following sections. FileNo is the handle created by the FreeFile function. Essential parameters must be enclosed in parentheses after the function or procedure names. A number of UNO objects support the supportsService method, with which you can establish whether an object supports a particular service. These objects cover not only the options, but also the current search text and, if necessary, the associated text replacement. The letter A stands for the column and the number 1 for the row. The characters are not rotated. You can use these events to, for example, determine if a user has finished processing a control element so that you can update other elements of a dialog. List boxes (com.sun.star.awt.UnoControlListBox service) support the following properties: List boxes provide the following methods: The model object of the list boxes provides the following properties: Note: If there is another line inwards, it marks the transition to a filled area. com.sun.star.chart.ChartTitle contains not only the listed formatting properties, but also two other properties: The legend (com.sun.star.chart.ChartLegend) contains the following additional property: The following example creates a chart with a title "Main Title String", a subtitle "Subtitle String" and a legend. For all axes an additional title can be displayed. Such CellRange objects are created using the getCellRangeByName call of the spreadsheet object: A colon (:) is used to specify a cell range in a spreadsheet document. Large sections of the basic constructs of LibreOffice Basic are compatible with Visual Basic. A spreadsheet consists of a two-dimensional list containing cells. A LibreOffice Basic program can contain dozens, hundreds, or even thousands of markers, which are names for variables, constants, functions . The type declaration symbol is #. Note: All objects that support the com.sun.star.text.Paragraph service also provide support for the paragraph properties in com.sun.star.style.ParagraphProperties. Note: 12 for Calc); the OpenOffice Basic Wikipedia page has some useful links, including: the OO Basic Guide and Andrew Pitonyak's OpenOffice Macro Information; there's also a book, Learn OpenOffice.org Spreadsheet Macro Programming from Pakt . When you select an option, all the other options in the group are deactivated. Note: It converts a string into a number; however it always expects a period to be used as the decimal point symbol. If the document has already been assigned a URL and is not a read-only document, it is saved under the existing URL. Since LibreOffice Basic is a procedural programming language, several linguistic constructs have had to be added to it which enable the use of UNO. The named _blank value for the Frame parameter ensures that LibreOffice creates a new window for every call from loadComponentFromURL. return the number of pages, words, or characters of a text. The com.sun.star.container.XNameContainer interface provides a method to remove a sheet of a given name: Each sheet contains a list of its rows and columns. en The waiting period is specified in milliseconds. It can, for example, be moved into the next line if a line break occurs. LibreOffice is an open source, cross-platform, office suite, made up of six main applications, and lots of other useful stuff. You can define modules to be global or part of a document. 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. The options for defining color gradients and hatches let you create other colors into play. VBA: Whereas the structure of an object in VBA is defined by the class to which it belongs, in LibreOffice Basic the structure is defined through the services which it supports. For charts in which the values of the various rows of data deviate significantly from one another, LibreOffice provides a second X and Y-axis for second scaling operations. storeAsURL provides the following options: The following example shows how the Overwrite option can be used in conjunction with storeAsURL: The example then saves Doc under the specified file name if a file already exists under the name. In place of the $ placeholder, the Format function displays the relevant currency symbol defined by the system (this example assumes a European locale has been defined): The format instructions used in VBA for formatting date and time details can also be used: LibreOffice Basic provides the Date data type, which saves the date and time details in binary format. You can also have loops with an undefined number of passes. Apache OpenOffice offers a complete user interface for developing programs in Basic. LibreOffice control elements recognize different types of events that can be triggered in different situations. Each type of style provides a whole range of individual formatting properties. The following example lists the most important syntax variants: Now consider a misleading (advanced) example, and a common error: The statement (Var = 8) evaluates to TRUE if Var is 8, and FALSE otherwise. Note: Jumping directly to a general program procedure from a macro can result in unclear code. Note: In Example 1, the page is accessed by its number (counting begins at 0). Like bubbles, the variables gradually migrate to the right position. The insertByName line inserts the NewStyle style under the name of the same name in the ParagraphStyles object. 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. This chapter provides an introduction to the macro-controlled creation and editing of drawings and presentations. It could be for example, A247. Note: The WithEnd With bracketing statements provide an alternative to writing out all the qualifiers, every time and some of the qualifiers in the API can be quite long. 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 includes the distance of the paragraph from the edge of the page as well as line spacing. In LibreOffice Basic, you can use object parameters to provide more information about an event to a procedure, for example: The structure and properties of the Event object depend on the type of event that triggers the procedure call. The previous section has already discussed a whole range of options for editing text documents, focusing on the com.sun.star.text.TextPortion and com.sun.star.text.Paragraph services, which grant access to paragraph portions as well as paragraphs. A For Each loop says "do this to everything in this set", rather than "do this n times". The following example shows how to create a chart assigned to some cell ranges within a spreadsheet document: Although the code used in the example may appear to be complex, the central processes are limited to three lines. To avoid this problem, the DateSerial function should be used to assign a fixed value to a date variable: The function parameter must be in the sequence: year, month, day. As the name suggests, LibreOffice Basic is a programming language from the Basic family. Both interfaces provide you with an object, through which the properties for searching and replacing can be defined. Microsoft based its Windows product on the American National Standards Institute (ANSI) character set, which was gradually extended to include characters that are missing from the ASCII character set. LibreOffice presentations are based on drawing documents. To improve clarity, you should avoid using Option Base 1. Note the last line in the example: Once the text is changed, the TextContent object must be assigned to the header again so that the change is effective. A text document can essentially contain four types of information: This section concentrates on the text and associated formatting options. OpenOffice.org BASIC Programming Guide 2 OpenOffice. In some situations, it is not the actual text of a document, but rather its structure that needs modifying. If there is no highlighted area, the text is inserted at the present TextCursor position. The following example shows how a bookmark can be found within a text, and a text inserted at its position. This detail may be of interest in particular to Java- or C++ programmers, since in these languages, the interface is needed to request a method. If you want to cleanly structure your code to prevent generating errors when you use this construct, you should not use jump commands without monitoring them.
