All the above debug tools work on a running program. The Chr command is often used in Basic languages to insert control characters in a string. Since LibreOffice Basic is a procedural programming language, several linguistic constructs have had to be added to it which enable the use of UNO. A Boolean value is saved internally as a two-byte integer value, where 0 corresponds to the False and any other value to True. The assignment. There are passed through in turn in a loop. A table consists of individual rows. The return value can be overwritten several times within the function. As these control elements are based on the UnoControlEdit Uno service, their program-controlled handling is similar. Styles deleted from the template are not removed from documents.

LibreOffice provides the com.sun.star.text.TextCursor service for more complicated tasks, including navigating backward within a document or navigating based on sentences and words rather than TextPortions. Drawing objects include shapes (rectangles, circles, and so on), lines, and text objects. For example, the methods and properties of the Z-axis, are available in 3D charts, but not in 2D charts, and in pie charts, there are no interfaces for working with axes. The code used in the example then creates a list containing all charts of the first spreadsheet (Charts line = Doc.Sheets(0).Charts). The objects are accessed as follows in text documents: The GetByIndex method returns the form with the index number 0. A text document can essentially contain four types of information: This section concentrates on the text and associated formatting options. These error messages can be avoided by checking the program before an assignment, in order to establish whether the content of the variable to be assigned matches the type of the target variable. This example uses the insertByIndex method to insert a new column into the fourth column position in the sheet (index 3 - numbering starts at 0). The service term used in LibreOffice Basic therefore corresponds to the type and class terms used in other programming languages. placeholders in both VBA and LibreOffice Basic. You specify the qualifiers in the With statement. In addition to the methods and properties of control elements, both dialog and control element objects have a subordinate Model object. The InputBox function queries simple strings from the user. This provides the following properties: The TextContent objects also share some methods in particular, those for creating, inserting and deleting objects. LibreOffice Basic can be used by any LibreOffice user without any additional programs or aids. A double variable can take up to eight bytes of memory. Note: Overview. (In the following examples, A > 10 represents any condition): As in the ForNext loop, the DoLoop also provides a terminate command. The corresponding counterparts of the TextCursor object in LibreOffice are described in the following sections. The following code is an example of an error handling procedure: This procedure begins with the definition of an error handler, followed by the actual program code. Some DOS-specific properties are no longer used in functions that expect file properties as parameters (for example, to differentiate from concealed files and system files). In LibreOffice Writer, standard letters can be created with the assistance of SDBC data sources and these can then be printed out. It supports the createTextCursor interface for creating an associated TextCursor object. This conversion is much more elaborate than it appears: the integer B remains in the working memory in the form of a two-byte long number. Note: In addition to the drawing functions that are provided by the Presentation property, the presentation document has a presentation object that provides access to the main properties and control mechanisms for presentations. LibreOffice Basic provides an extensive interface for program-controlled creation and editing of spreadsheets. The parameters are structured in the same way as the corresponding functions in XNameContainer. The replacement function of LibreOffice is particularly effective when used in conjunction with regular expressions. LibreOffice provides the com.sun.star.drawing.LineShape service for line objects. The example creates a TextTables list containing all tables of a text that are traversed in a loop. A global Dlg variable that references an open dialog must be included to make this example possible. Several TextCursor objects can even be opened for the same document and used in various positions, which are independent of one another. The Print method of the com.sun.star.view.Xprintable interface is provided for this purpose. The structure is further complicated by tables. The FilterOptions property contains the description of the syntax of the csv file. Any number of documents can be opened in this way in LibreOffice Basic and then edited using the returned document objects. This procedure differs from VBA. If this procedure was created in LibreOffice Basic, you can assign it to an event required using the property window of the dialog editor. It is called a ReplaceDescriptor and supports the com.sun.star.util.ReplaceDescriptor service. All of these charts support the com.sun.star.chart.StackableDiagram service, which in turn provides the following properties: Line charts (com.sun.star.chart.LineDiagram) support two X-axes, two Y-axes and one Z-axis. For more information about the LibreOffice API and the Software Development Kit, visit https://api.libreoffice.org. There are, however, also special drivers which access the MAPI address book, LDAP directories or LibreOffice spreadsheets as data sources. VBA: Unlike VBA, you cannot insert option buttons in a group of control elements in LibreOffice Basic. There is, however, one main difference: a Universal Network Object may support several services at the same time. Jumping directly to a general program procedure from a macro can result in unclear code. Example: Suppose that in your Basic library you have a module named PrintDoc. 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. This gradually returns the individual paragraphs of the text in a loop. With the aid of Doc, the example then creates an Enumeration object that traverses through the individual parts of the text (paragraphs and tables) and assigns the current element to TextElement object. This method is also defined in com.sun.star.frame.XStorable and can be used to define the location of the document: In addition to the preceding methods, com.sun.star.frame.XStorable also provides some help methods which are useful when saving documents. Integrated Development Environment (IDE) This section describes the Integrated Development Environment for LibreOffice Basic. Routine tasks can therefore be automated in LibreOffice Basic, links can be made to other programs for example to a database server and complex activities can be performed at the press of a button by using predefined scripts. Example declarations for integer variables: Long integer variables can store any whole number between 2147483648 and 2147483647. com.sun.star.frame.Desktop resembles an object type; however in UNO terminology it is called a service rather than a type. These may be outside the flow of text and can be positioned anywhere on the page. But text documents may also contain other objects. Its syntax is. However, unlike the old Application object, StarDesktop is primarily responsible for opening new documents. The best way to learn Python is a simple text editor with syntax highlighting. The underscore must always be the last character in a linked line and cannot be followed by a space or a tab or a comment, otherwise the code generates an error. 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. To determine the current cursor position, the following test methods are provided and all return a Boolean value: If a ResultSet has been created with the ResultSetConcurrency = UPDATEABLE value, then its content can be edited. LibreOffice then creates a list of the associated cell names for each of these tables. 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. 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. The associated constants are defined in the com.sun.star.sheet.GeneralFunction enumeration. The com.sun.star.presentation.PresentationDocument service, responsible for presentation documents, also provides the complete com.sun.star.drawing.DrawingDocument service. VBA: Unlike VBA, where only the upper limit of the last dimension of a data field can be changed through Preserve, LibreOffice Basic lets you change other dimensions as well. The following functions are available in LibreOffice Basic to retrieve the system time and system date: Working with files is one of the basic tasks of an application. The wall is set to be blue. The objective of developing this interface was to provide access to as many different data sources as possible. Like bubbles, the variables gradually migrate to the right position. To avoid other errors resulting from implicit type conversions, LibreOffice Basic offers a range of conversion functions, which you can use to define when the data type of an operation should be converted: You can use these conversion functions to define how LibreOffice Basic should perform these type conversion operations: During the first addition in the example, LibreOffice Basic first adds the integer variables and then converts the result into a chain of characters. When you click a button that has this property set to the value of 0, the dialog remains unaffected. Whereas the document object in VBA is called a Workbook and its individual pages Worksheets, they are called SpreadsheetDocument and Sheet in LibreOffice Basic. The following example shows how a database context can be created and then used to determine the names of all data sources available. Unlike most other programming languages, Basic performs type conversion automatically. The color intensity of the start and end colors is 150 percent (StartIntensity and EndIntensity) which results in the colors seeming brighter than the values specified in the StartColor and EndColor properties. Functions LBound() and UBound() return respectively the lowest permitted index value and the highest permitted index value of an array. The When initiating event is also noteworthy for the following reasons: The properties for the Item Status Changed event are: LibreOffice Basic recognizes a range of control elements which can be divided into the following groups: A button performs an action when you click it. LibreOffice Basic predefines several constants. In LibreOffice Basic, the directory and all its files are deleted. The Model property provides program-controlled access to the model of dialog and control element objects. The text can only be inserted after the drawing object has been added to the drawing page. For all axes an additional title can be displayed. Since the drivers are based on UNO components, other drivers can be developed and therefore open up new data sources. VBA: If a string in LibreOffice Basic contains a non-numerical value and if this is assigned to a number, LibreOffice Basic does not produce an error message, but stops converting the string at the first invalid character. Even the paragraph properties are available in various objects. Furthermore, the SearchFlags parameter must be set so that the corresponding framework is created, if it does not already exist. For a more detailed picture, see the API reference. These include the previously described com.sun.star.text.Paragraph services for paragraphs as well as the com.sun.star.text.TextPortion services for paragraph portions. Set focus. LibreOffice Basic supports Modules and Libraries. The following example shows how all text fields of a text document can be traversed in a loop and checked for their relevant type. All formatting options for individual characters and paragraphs are therefore automatically available. Unlike the data sources presented in the previous section, the database connection must therefore be re-established every time the program is restarted. It may not be available in all types of documents. Multiple modules can be combined to a library. You can also benefit from the advantages of object-oriented programming since an interface in LibreOffice Basic enables you to use external object libraries. A long integer variable can take up to four bytes of memory. For example: The DoLoop is not linked to a fixed number of passes.
