The type is declared in the same way as a variable declaration: If the return type is not specified (see first example of this page), the function returns a variant. The example creates a text frame, inserts this in the current document and opens a TextCursor for the text frame. To assign a macro to an event: The occurrence of a particular event is not always enough for an appropriate response. Download PDF. To simplify access to the tables, LibreOffice, however, provides some methods which operate using columns. More information about the available services, and their interfaces, methods and properties can be found in the reference for the LibreOffice API. It displays the names in a message box. The property has been virtually imitated from two methods. The first 128 characters of the ISO character set correspond to the ASCII character set. A LibreOffice Basic program can contain dozens, hundreds, or even thousands of markers, which are names for variables, constants, functions . Buy a printed copy. For example, you can check whether a user has typed a valid number or date. The syntax of such method calls is oriented towards classic functions. The properties for formatting headers are: The properties for formatting footers are: The content of headers and footers in a spreadsheet is accessed through the following properties: If you do not need to distinguish between headers or footers for odd and even pages (the FooterIsShared property is False), then set the properties for headers and footers on odd pages. In this instance, the storeAsURL method is used. The option of creating sub-forms is also provided for this purpose. This is used to define a gradient that specifies the transparency of a fill area. The simplest scenario is for the button to trigger a When Initiating event when it is clicked by a user. The following example shows how all text fields of a text document can be traversed in a loop and checked for their relevant type. Here, the methods are called directly by means of the relevant object. Upon closer inspection, the following code sequence. The recursion levels are set at different levels based on the software platform. It returns the document object on which the macro is run. Then it iterates through the entire text, sentence by sentence, and highlights each of the first words and formats this in bold. 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 assign a floating point number to an integer variable, the number is rounded up or down to the next whole number. Buy a printed copy. If this is true, the function ends the search. For a detailed description please refer to the LibreOffice Basic Guide which is available separately. It is important to check the error number so that unanticipated errors can be detected. The com.sun.star.view.XPrintable interface, which contains the methods for printing documents. 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. Anyone who has already worked with these languages can quickly become accustomed to LibreOffice Basic. This gradually returns the individual paragraphs of the text in a loop. If a cell contains a numerical value, then the example changes the formatting correspondingly. LibreOffice also supports complex polygonal shapes through the com.sun.star.drawing.PolyPolygonShape service. LibreOffice is an open source, cross-platform, office suite, made up of six main applications, and lots of other useful stuff. Note: VBA: When requested in LibreOffice Basic, the Dir function, using the parameter 16, only returns the sub-directories of a folder. When LibreOffice Basic encounters an incorrectly defined variable type in a particular context, an error message is generated. At the end, the drawing object is assigned to a page using a Page.add call. A database connection is needed for access to a database. These in turn contain the various cells. In some instances, the date cannot be converted: In the example shown, the assignment of the test string to a date variable makes no sense, so the Basic interpreter reports an error. As in the old API from LibreOffice, searching and replacing text in the new API is also performed using the document object. In LibreOffice Writer, standard letters can be created with the assistance of SDBC data sources and these can then be printed out. The second parameter of insertCells contains a value of the com.sun.star.sheet.CellInsertMode enumeration and defines what is to be done with the values that are located in front of the insert position. The example creates an Enumeration object on the basis of this list, with which all text fields can be queried in turn in a loop. A simple ResultSet, provides the minimum scope of functions available. As with the loadComponentFromURL method, some options can also be specified in the form of a PropertyValue data field using the storeAsURL method. The interfaces to various LibreOffice applications, which allow for direct access to Office documents. The hasByName, getByName and insertByName methods are obtained from the com.sun.star.container.XNameContainer interface as described in #Introduction to the API. The wall is set to be blue. The steep learning curve is not imposed by your chosen language. For more complex statements, you can cascade the If statement, for example: If the value of variable A equals zero, B is assigned the value 0. Like bubbles, the variables gradually migrate to the right position. The return value is provided as a bit mask in which the following values are possible: The following example determines the bit mask of the test.txt file and checks whether this is read-only whether it is a directory. A complete list of the paragraph properties can be found in the LibreOffice API reference. Note: Until Basic encounters the End With statement, it looks for partly-qualified names: names that begin with a period (unary dot-operator). Currency variables are mostly intended for business calculations that yield unforeseeable rounding errors due to the use of floating point numbers. English documentation | LibreOffice Documentation - LibreOffice User Guides en / English documentation English documentation Getting Started Books Buy a printed copy Download PDF Guide Source Files Website Buy a printed copy Download PDF Download Source Files Read in your browser Buy a printed copy Download PDF Download Source Files The previous example creates a bar chart. If the text of the paragraph is now changed using the paragraph's String property, then LibreOffice first deletes the old paragraph portions and inserts a new paragraph portion. In LibreOffice Basic, this is accomplished with the On Error or Resume commands. A currency variable can store any value between -922337203685477.5808 and +922337203685477.5807 and takes up to eight bytes of memory. Working with LibreOffice Basic In other words, code (like the above examples) that works in a particular document type should also work for the associated template type. A single variable can take up to four bytes of memory. This example inserts a cells range that is two rows by two columns in size into the second column and row (each bear the number 1) of the first sheet (number 0) in the spreadsheet. LibreOffice Basic saves strings as string variables in Unicode. Finally, the following information symbols are available and can also be displayed by adding the relevant parameter values: The following call displays an information box with the Yes and No buttons (value 4), of which the second button (No) is set as the default value (value 256) and which also receives a question mark (value 32), 4+256+32=292. Programmers who want to work directly with Java or C++ rather than LibreOffice Basic should consult the LibreOffice Developer's . As the name suggests, LibreOffice Basic is a programming language from the Basic family. Before accessing a returned object, you should therefore check whether the returned object supports the com.sun.star.text.Paragraph service for paragraphs or the com.sun.star.text.TextTable service for tables. One of these is used to query the value of the property and the other is issued to set it (get and set methods). createUnoService creates an object which can be used universally. The following example lists the names of data source queries can be established in a message box. If you want to delete directory (including its files) use the RmDir function. The page properties that are valid for both types of documents are defined in the com.sun.star.style.PageProperties service. You can access individual pages either through their number or their name. "LibreOffice" and "The Document Foundation" are registered trademarks of their corresponding registered owners or are in actual use as trademarks in one or more countries. 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. The selection ranges from simple text fields through list and combo boxes to various buttons. Note: An example for the grouped option button: Text fields allow users to type numbers and text. Whereas cell, paragraph, and character elements can be formatted directly, page formats can also be defined and indirectly applied using page styles. The method provides the result in the form of a string. 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). This can be compared with highlighting a point in the text using the mouse. Numbers can be inserted and called up with the Value property, text with the String property, and formulas with the Formula property. So Replace("This is a test", " ", "_") yields "This_is_a_test" :D. Warning: The question remains as to which objects or services if we are going to remain with UNO terminology support which properties, methods and interfaces and how these can be determined. You can also move data from the database window into text documents using the drag-and-drop function. The Map AppFont (ma) replaces the Twips unit to achieve better platform independence. LibreOffice Basic provides two functions to convert lowercase characters in a string to uppercase and vice-versa. documents = StarDesktop.getComponents () enumeration = documents.createEnumeration () Do While enumeration.hasMoreElements () doc = enumeration.nextElement () window = doc.CurrentController.Frame.ComponentWindow window.setFocus () REM Sleep 1.5 seconds Wait 1500 Loop. For more information, see the LibreOffice API reference. If you want to administer a numerical value (for example a database ID) in addition to the natural language text, you must create an auxiliary data field that administers in parallel to the list box. The second parameter of Dir specifies whether files or directories are to be searched for. As a function, CompatibilityMode() returns the Boolean value of the mode. To avoid such blind events, save the old control element value in a global variable, and then check to see if the value has changed when an event is executing.
