libreoffice basic programming guide pdf

While test functions exist for checking numbers, date details and arrays in LibreOffice Basic, a corresponding function for checking Boolean values does not exist. The insertCell method is used to insert cells into a sheet. The & operator is safer when dealing with strings because it assumes that all arguments should be strings, and converts the arguments to strings if they are not strings. The descriptor objects for searching and replacing in spreadsheet documents are not created directly through the document object, but rather through the Sheets list. Numbers can be inserted and called up with the Value property, text with the String property, and formulas with the Formula property. In the following example the A parameter is obligatory, whereas the B parameter is optional. If a corresponding model is found, then a reference to this is saved in the Ctl variable and the search is terminated. Only at run-time can you find out which properties or methods are available for an object. If the directory contains sub-directories or files, these are also deleted. To make the definition available to other modules, add the Public keyword. You can access these elements through the getControl method that returns the control element by name. There are various ways of formatting text. For example charts in spreadsheets can display data obtained from the cell ranges and charts in text documents can display data obtained from writer tables. The search expression sh.rt therefore can stand for both for, The character ^ marks the start of a paragraph. The first example of this page may be written as: The second example of this page may be written as: The SelectCase instruction is an alternative to the cascaded If statement and is used when you need to check a value against various conditions: In this example, the name of a weekday corresponds to a number, so that the DayOfWeek variable is assigned the value of 1 for Sunday, 2 for Monday value, and so on. Note: The Assign Action dialog lists all the available Events. A default value which can be added within the input area. If on the other hand, the example encounters another field, then it displays the information unknown. To do so, the method of formatting individual table cells must be used. Charts are not treated as independent documents in LibreOffice, but as objects that are embedded in an existing document. The value is then changed to 20 and passed to TheValue, which is retained when the function is exited. It accesses the array of models using the GetGroupByName method (rather than the GetByName method to determine simple models). Since these function areas are available in all types of documents, they are explained first in this chapter. The following example changes the dimension of the initial array so that it can record 11 or 21 values: When you reset the dimensions of an array, you can use any of the options outlined in the previous sections. The user interface provides a corresponding option for creating data sources in the Extras menu. The working memory needed for a string variable depends on the length of the string. Example declarations of double variables: Currency variables differ from the other variable types by the way they handle values. Once the message box has been confirmed, it replaces the content of the window with the test2.odt file. The ResultSet object provides Update methods for modifying values, which are structured in the same way as the get methods for retrieving values. If neither of these apply, FileDescription is assigned the "normal" string. In VBA, the function also returns the names of the standard files so that further checking is needed to retrieve the directories only. The command: specifies the same delay, 2 seconds, as the previous example. With the help of this controller object and the model of the control element, it then uses the GetControl method to determine the view (CtlView variable) of the control element form. LibreOffice Basic Macro Tutorials StarOffice (Basic) programmer's Tutorial, May 2000 LibreOffice API LibreOffice scripts make use of the LibreOffice API , documentation is available at: api.libreoffice.org OpenOffice.org 3.1 Developer's Guide Developer's Guide new home in LibreOffice wiki ScriptForge Library LibreOffice Programming The TextCursor object in LibreOffice Basic acts independently from the visible cursor in a text document. VBA: Whereas the active document in Word is accessed through Application.ActiveDocument and in Excel through Application.ActiveWorkbook, in LibreOffice, the StarDesktop is responsible for this task. They define sets of methods for abstract tasks which can be applied to various problems. The text frame is created using Doc.createInstance. The following keyboard events are available in LibreOffice Basic: Both events relate to logical key actions and not to physical actions. Apache OpenOffice - Official Site - The Free and Open Productivity Suite Note: The date is formatted here in accordance with the country-specific settings used on the system. These are available through the Rows and Columns properties of the spreadsheet object and support the com.sun.star.table.TableColumns and/or com.sun.star.table.TableRows services. The FileExists function can be used to check whether a file exists: When working with files, it is sometimes important to be able to establish the file properties, the time the file was last changed and the length of the file. The following example also shows a correct declaration, but with negative data field limits: It declares an integer data field with 6 values that can be addressed using the indexes -10 to -5. When the dimensions of the data field are changed, all contents are lost. These variables are available to all the modules in their library: The value of variable A is not changed by the Test function, but is increased by one in the Flip function and decreased by one in the Flop function. SetModuleB is triggered from one toolbar button and ShowVarB is triggered from another toolbar button, then ShowVarB will display a C value of 0 since module variables are reset after each macro completion. 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. As an alternative, a validity range with start and end values can be specified for the data field declaration. In addition to the properties for characters (com.sun.star.style.CharacterProperties service, refer to #Text Documents) and lines (com.sun.star.drawing.LineStyle service, refer to #Drawings and Presentations), it provides the following properties: For the primary axes grids and sub grids can be displayed, matching to the major and minor intervals. If you are interested in only the mouse click, your macro should ignore all calls where PopupTrigger is TRUE. Context-dependent objects are usually created by means of an object method, on which the object depends. VBA: The path specifications listed in Dir may use the * and? In other words, formatting using templates is assigned a lower priority than direct formatting in a text. Note: The second parameter of Dir specifies whether files or directories are to be searched for. The individual data sources are based on the com.sun.star.sdb.DataSource service and can be determined from the database context using the getByName method: The example creates a DataSource object for a data source called Customers. Before a text file is accessed, it must first be opened. LibreOffice recognizes a whole range of services that support this service. InputBox receives three standard parameters: The Beep function causes the system to play a sound that can be used to warn the user of an incorrect action. The selection ranges from simple text fields through list and combo boxes to various buttons. You will find a range of examples which use these methods in the following sections. Note - VBA : Compatibility between OpenOffice.org Basic and VBA relates to the OpenOffice.org Basic language as well as the runtime library. Write it before the inner name, and separate it by a period: Since containers may hold other containers, you may need more than one qualifier. The control elements available in forms are similar to those of dialogs. In addition to the methods and properties of control elements, both dialog and control element objects have a subordinate Model object. The control codes are defined in the com.sun.star.text.ControlCharacter group of constants. Throughout this document, the LibreOffice installation directory is represented in syntax as install-dir. In addition to the Name property used in the example, the com.sun.star.sdb.QueryDefinition provides a whole range of other properties. Drawing objects include shapes (rectangles, circles, and so on), lines, and text objects. If a style in the template has been changed, and you open a document created with that template, you will see a message asking whether to update the styles in the document. The following path references the test.odt file in the doc directory on the C: drive: file:///C:/doc/test.odt Its syntax is. WaitUntil takes a parameter of type Date, with a combined date and time value. There is no type declaration symbol for date variables. Graphic objects support two of the general formatting properties: Additional properties that are supported by graphic objects are: The following example shows how to insert a page into a graphics object. You can also use plus (+) or minus (-) signs as prefixes for decimal numbers (again with or without spaces). However, this is not sufficient for many problems. After the call for the ChangeValue function, variable A retains the value 10. The query object is first created using the createUnoService call, then initialized, and then inserted into the QueryDefinitions object by means of insertByName. The associated com.sun.star.form.FormButtonType group of constants provides the following values: The OK and Cancel button types provided in dialogs are not supported in forms. The com.sun.star.style.CharacterProperties and com.sun.star.style.ParagraphProperties services can format text in drawing objects. The example creates a text frame, inserts this in the current document and opens a TextCursor for the text frame. In the previous example, if the UserInput variable contains a valid numerical value, then this is assigned to the ValidInput variable. libreoffice basic programming guide pdf By July 27, 2021 OpenOffice Basic . As the size of the legend and the titles is calculated automatically based on the current content and the character height for example, the size property provides read access only. A long integer variable can take up to four bytes of memory. You can access individual pages either through their number or their name. Depending on the system and configuration, various types of data are saved here. Note: StarOffice 5: The Range object allows you to address any table area and has been extended in the new API. To compare the differences between different SQL dialects, the SDBC components from LibreOffice have their own SQL parser.

All formatting options for individual characters and paragraphs are therefore automatically available. If the cursor of LibreOffice is in a cell, then the name of that cell can be seen in the status bar. Here are a few examples of correct and incorrect markers: Enclosing a variable name in square brackets allows names that might otherwise be disallowed; for example, spaces. All the named objects return an object that supports the com.sun.star.sheet.HeaderFooterContent service. Let us first take the properties of the table itself. These commands stop the procedure or function and return the program to the point at which the procedure or function was called up. The CompatibilityMode statement and function provide greater compatibility with VBA, by changing the operation of certain functions. You can apply all the named properties to individual cells and to cell ranges. LibreOffice Basic provides an extensive interface for program-controlled creation and editing of spreadsheets. The interaction between the AnchorType (from the TextContent Service) and VertOrient (from the BaseFrameProperties Service) properties should be noted here. The LibreOffice API provides you with a whole range of objects with which you can create, open and modify Office documents. The XNameContainer interface takes on the insertion, deletion and modification of subordinate elements in a basic object. To continue a program without an error message when an error occurs, use the following format: Use the On Error Resume Next command with caution as its effect is global. The following example activates the automatic height optimization for the first five rows in the sheet and makes the second column invisible. With the TypeEnd Type statements, you can define your own (non-UNO) structs: The Type definition is only a pattern or template, not a set of actual variables. You should therefore be careful when using RmDir. The method provides the result in the form of a string. Common pieces of reusable Python or UNO features must be stored in My macros within (User Profile)/Scripts/python/pythonpath. In other terms, you may think of a struct as a record, or part of a record. To make this possible, data sources are accessed by drivers. The reference CellStyles(I) corresponds to the method getByIndex(), which is optional for these style container objects. RectangleShape.String = "This is a test" For a more detailed picture, see the API reference. Text frames are considered to be TextContent objects, just like tables and graphs. To do this, you first create a standard LibreOffice Writer or LibreOffice Calc form and then link the fields to a database. XIndexAccess provides the methods for accessing individual objects. LibreOffice forms may contain text fields, list boxes, radio buttons, and a range of other control elements, which are inserted directly in a text or spreadsheet. You should instead use Basic object ThisComponent. The text frame is created using the createInstance method of the document object. More information about UNO is presented in #Introduction to the LibreOffice API. The following example creates a rectangle and tiles the Sky bitmap that is available in LibreOffice to fill the area of the rectangle: You can adjust the transparency of any fill that you apply. The second section concentrates on how to edit spreadsheets efficiently by focusing on cell areas and the options for searching and replacing cell contents. The bars can be stacked (com.sun.star.chart.StackableDiagram). The following properties are available in this context in the control elements model: Finally, the control element provides a setFocus method that ensures that the underlying control element receives the focus: A dialog in LibreOffice can have more than one tab page.
