Display of the Message Box. As a statement, CompatibilityMode( value ) takes a Boolean value to set or clear the mode. The amount of time that a variable is retained, as well as where it can be accessed from, depends on its specified location and type. Information about creating, opening, and saving drawings can be found in #Working With Documents. In LibreOffice, these properties are defined using a page style which in turn is linked to the associated document. If a corresponding model is found, then a reference to this is saved in the Ctl variable and the search is terminated. The same applies when attempting to assign a string to a Boolean variable: Again, the basic interpreter reports an error. In LibreOffice Basic, this is accomplished with the On Error or Resume commands. If you want to change the size or position of control elements for runtime, determine the total size of the dialog and adjust the values for the control elements to the corresponding part ratios. The following example demonstrates the use of ReplaceDescriptors for a search within a LibreOffice document.

For a multi-dimensional array you need to specify the position (1 to n) of the index you want to know the permitted lower and upper values: In some cases, especially when dealing with the API, you need to declare an empty array. As the name suggests, LibreOffice Basic is a programming language from the Basic family. The expression MB_YESNOCANCEL + MB_DEFBUTTON3 is harder to write, but easier to understand. VBA: A ResultSet containing the READ_ONLY and SCROLL_INSENSITIVE properties corresponds to a record set of the Snapshot type in ADO and DAO. To check if the contents of a cell contains a number or a string, use the Type property: The Cell.Type property returns a value for the com.sun.star.table.CellContentType enumeration which identifies the contents type of a cell. Constants have the same scope as variables (see #Scope_of_Variables Scope and Life Span of Variables), but the syntax is slightly different. Accessing databases is often a matter of critical speed. 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. You can also define arrays in which the dimension of the data fields dynamically changes. 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. Objects that allow character properties to be set have to support the com.sun.star.style.CharacterProperties service. Note: The shape object of the control element must already be known if the code is to function. LibreOffice Basic also offers several other services through which you can modify such properties, as formatting or apply fills. The LibreOffice Developer's Guide describes the LibreOffice API in more detail than this guide, but is primarily intended for Java and C++ programmers. Others use standard interfaces such as JDBC or ODBC. An interface combines several methods. The FilterOptions property contains the description of the syntax of the csv file. For example, if only the C:\SubDir1 directory exists, then a call. Once the database connection has been established, the code used in the example first uses the Connection.createObject call to create a Statement object. As with rectangle shapes, all the formatting properties of drawing objects are also provided for polypolygons: The PolyPolygonShape service also has a property that lets you define the coordinates of a polygon: The following example shows how you can define a triangle with the PolyPolygonShape service. These include bold type and the font type. A drawing object for a spreadsheet document, for example, can therefore only exist in conjunction with this one document. The bookmarks can either be accessed by their number or their name. The service provides the following properties: The following example creates a rectangle and rotates it by 30 degrees using the RotateAngle property: The next example creates the same rectangle as in the previous example, but instead shears it through 30 degrees using the ShearAngle property. However, these speed considerations no longer apply, reducing the need for single variables. com.sun.star.awt.UnoControlCurrencyField. The Select Case statement evaluates the expression, which is TRUE or FALSE, and then compares that value to Var. Direct formatting is used in particular with short documents because the formats can be assigned by the user with the mouse. A default value which can be added within the input area. Finally, when calling up a text file, the eof instruction is used to check whether the end of the file has been reached: The following example shows how a text file can be read: The individual lines are retrieved in a Do While loop, saved in the Msg variable, and displayed at the end in a message box. The user interface provides a corresponding option for creating data sources in the Extras menu. To determine a special control element, all drawing elements of the drawing level must be searched through. When it is used with 4 arguments, to replace a sub-string in a string, Mid is an instruction, not a function: it does not return any value! If you want to increment the loop counter by a value other than 1 at the end of each pass, use the Step function: In the preceding example, the counter is increased by 0.5 at the end of each pass and the loop is executed 19 times. This code determines the object for the MyButton control element and then initializes the Ctl object variable with a reference to the element. If the center of a paragraph, for example, contains a word printed in bold, then it will be represented in LibreOffice by three paragraph portions: the portion before the bold type, then the word in bold, and finally the portion after the bold type, which is again depicted as normal. Note: The command: specifies the same delay, 2 seconds, as the previous example. 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 Model property provides program-controlled access to the model of dialog and control element objects. When you select an option, all the other options in the group are deactivated. The StarDesktop object replaces the Application object of StarOffice 5 which previously applied as a root object. It supports the createTextCursor interface for creating an associated TextCursor object. Essential parameters must be enclosed in parentheses after the function or procedure names. The LibreOffice API provides two options for creating objects. = 1. Note: If nothing is assigned, the function returns a zero value (number 0 for numerical values and a blank for strings). A global Dlg variable that references an open dialog must be included to make this example possible. In LibreOffice Basic, the * placeholder may however only be the last character of a file name and/or file extension, which is not the case in VBA. A fuller description of this facility is beyond the scope of this document, but more information can be found in the Help system. The procedure for defining page formats differs from other forms of formatting. LibreOffice Writer supports the following types of styles: LibreOffice Calc supports the following types of styles: LibreOffice Impress supports the following types of styles: In LibreOffice terminology, the different types of styles are called StyleFamilies in accordance with the com.sun.star.style.StyleFamily service on which they are based. value in the left-hand text field of the header from the "Default" template. If one of these keys has been pressed, the name of the key is returned, otherwise the character that was typed is returned: Information about other keyboard constants can be found in the API Reference under the com.sun.star.awt.Key group of constants. The control element can be reached using Event.Source and its model using Event.Source.Model. The runtime library: Provides standard functions which have no direct reference to LibreOffice, for example, functions for editing numbers, strings, date values, and files. Styles deleted from the template are not removed from documents. The Assign Action dialog lists all the available Events.

The reference CellStyles(I) corresponds to the method getByIndex(), which is optional for these style container objects. chapter #Programming Dialogs and Dialog Controls shows more examples in Basic. The two empty strings in the command line stand for the user name and password. In addition to pure strings, text documents also contain formatting information.

This chapter presents the central interfaces and services of text documents. Standard file names using this system begin with the prefix file:/// followed by the local path. If you assign a floating point number to an integer variable, the number is rounded up or down to the next whole number. Line objects support all the general formatting services with the exception of areas. Example declaration of a string variable: Note: The fill mode of a drawing object is defined using the FillStyle property. The topmost link in this forum's Macros and API Forum provides a good starting point. 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. The dialog can be reached using Event.Source.Context. In addition to these "real" properties, there are also properties in LibreOffice Basic which consist of two methods at the UNO level. 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. Literals are enclosed between hash signs #. The FreeFile function is used to create a free file handle: FileNo is an integer variable that receives the file handle. 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. In many instances, it is the case that a text is to be searched for a particular term and the corresponding point needs to be edited. 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. 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. The assignment. All characters that follow an apostrophe are treated as comments: Markers can only contain Latin letters, numbers, and underscores (_). File:Pictures/10000200000001FA0000020F3B892B46.gifThe LibreOffice Basic development environment. 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: Some UNO services in turn support other services so that, through one object, you are provided with a whole range of services. They can be displayed as 2D or 3D graphics (com.sun.star.chart.Dim3DDiagram service). If the PushButtonType has the value of 2, the dialog is closed and the Execute method of the dialog returns the value 0 (dialog closed). The Print method of the com.sun.star.view.Xprintable interface is provided for this purpose. You can also pass a parameter as a value if you do not want subsequent changes to the parameter to affect the value that is originally passed. The example first creates a list containing all rows using a Table.getRows call. libreoffice 6 0 6 2 To do this, all option buttons of a group must contain the same name. The following example shows how all element names of a spreadsheet can thereby be determined and displayed in a loop: The hasByName method of the XNameAccess interface reveals whether a subordinate object with a particular name exists within the basic object. The headers and footers of a document form part of the page properties and are defined using the com.sun.star.style.PageProperties service. The paragraph properties are available through the com.sun.star.style.ParagraphProperties service. The ASCII character set is commonly used as a standard format for transferring text data between computers. You can create and structure dialogs using the LibreOffice dialog editor: You can drag the control elements from the design pallet (right) into the dialog area, and define their position and size. Finally, LibreOffice provides a mechanism for forms based on databases. 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 following values are included in this structure: The completed CellRangeAddress structure must be passed as the first parameter to the insertCells method. Before you can create the dialog, you must ensure that the library it uses (in this example, the Standard library) is loaded. This event is also used for notifying requests for a popup context menu on the control. The example inserts one number, one text, and one formula in the fields A1 to A3. Note: To convert a URL into a local file name, LibreOffice provides the ConvertFromUrl function: The example converts a local file name into a URL and displays it in a message box. Here we rename the first sheet of the spreadsheet document. The code in the following example moves an entry from the left to the right list box of a dialog. The following example activates the automatic height optimization for the first five rows in the sheet and makes the second column invisible. 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. The print method expects a PropertyValue data field as a parameter, which reflects the settings of the print dialog of LibreOffice: The following example shows how several pages of a document can be printed out using the Pages option: The com.sun.star.view.XPrintable interface provides the Printer property, which selects the printer. The code listed in the example is very similar to the code listed in the previous example for determining a control element model. These determine the procedure LibreOffice uses when saving a document. Such array is declared without dimension, but may later be filled by an API function or with a Redim statement: You cannot assign a value to an empty array, since it does not contain any elements. Each cell of a LibreOffice document has a unique name. The following example creates an object that references the top left cell and inserts a text in the cell: In addition to numerical coordinates, each cell in a sheet has a name, for example, the top left cell (0,0) of a spreadsheet is called A1. libreoffice 6 0 6 2 A Draw (or Impress) document is composed of pages, also called slides. In this course, it is assumed that you are a beginner in office software but have a grasp of the basic concepts. 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. Content on this page is licensed under the Public Documentation License (PDL). Any number of documents can be opened in this way in LibreOffice Basic and then edited using the returned document objects. The com.sun.star.awt.UnoControlEdit service forms the basis for text fields. In LibreOffice Basic, you can use the Exit Sub and Exit Function commands to terminate a procedure or function prematurely, for example, for error handling. Note: An integer variable can take up to two bytes of memory. The dispose method at the end of the code releases the resources used by the dialog once the program ends. A chart may contain its own data or may display data from the container document.
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. This allows numbers to be handled in a manner which more closely reflects machine architecture. VBA: The page properties (page margins, borders, and so on) for a Microsoft Office document are defined by means of a PageSetup object at the Worksheet object (Excel) or Document object (Word) level. Here is an list of the most important properties of the table object: A table consists of a list containing rows. In addition to the program code to be executed, an LibreOffice Basic program can also contain comments that explain the individual parts of the program and provide important information that can be helpful at a later point. This example removes the B2:C3 cell range from the sheet and then shifts the underlying cells up by two rows. The Diagram object provides the following properties to access the axes: The axis objects of a LibreOffice chart support the com.sun.star.chart.ChartAxis service. The removeByIndex method deletes the sixth column (index 5). They work in all applications of LibreOffice and help to significantly simplify formatting.
