libreoffice basic programming guide pdf

A complete If statement may be written on a single line, with a simpler syntax. More information about working with these buttons is discussed in #Control Elements in Detail. The following program code shows how the Step value in event handlers of the Next and Prev buttons can be increased or reduced and changes the status of the buttons. VBA: In VBA, the Err.Clear method of the Err object resets the error status after an error occurs. The Dir function in LibreOffice Basic is responsible for searching through directories for files and sub-directories. This ensures that at any one time, only one option button is set. If you click on Yes, the new or changed styles will be copied into the document. VBA: Whereas VBA summarizes the error messages in a statistical object called Err, LibreOffice Basic provides the Err, Error$, and Erl variables. 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 Diagram object provides the following properties to access the axes title: and for the secondary axes (available since OpenOffice.org 3.0): The objects for formatting the axes title are based on the com.sun.star.chart.ChartTitle service, which is also used for chart titles. All directories needed within a hierarchy are also created, if required. The following example creates two objects that reference the first row and the first column of a sheet and stores the references in the FirstCol and FirstRow object variables. For an understanding of the API, it is, however, useful to have the assignment of methods to various interfaces handy, since many interfaces are used in the different services. For more information, see the LibreOffice API reference. These in turn can be linked to LibreOffice Basic macros to considerably extend the usage range of LibreOffice Basic. It uses not only the Doc document object but also the DocCrl document controller object which makes reference to the current document window. Queries are used to simplify working with databases because they can be opened with a simple mouse click and also provide users without any knowledge of SQL with the option of issuing SQL commands. However, this is not sufficient for many problems. LibreOffice then creates a list of the associated cell names for each of these tables. These are defined in the com.sun.star.text.TextTable service. In other words, the methods are assigned (as combinations) to the service in interfaces. Sunday is considered the first day of the week. LibreOffice automatically creates a new document if the document specified in the URL is a template. The FilterOptions property contains the description of the syntax of the csv file. which provides LibreOffice with various options for opening and creating documents. 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. Some of the properties that this service provides are: The following example creates a rectangle with a solid border (LineStyle = SOLID) that is 5 millimeters thick (LineWidth) and 50 percent transparent. Any existing values in the specified cell range are moved below the range. An ma unit is defined as being one eighth of the average height of a character from the system font defined in the operating system and one quarter of its width. 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 following example formats the B2 cell so that numbers are displayed with three decimal places and use commas as a thousands separator. The following example checks whether the date saved in MyDate is in the year 2003. The hasByName and getByName methods are obtained from the com.sun.star.container.XNameAccess interface. Furthermore, it creates a data field for two PropertyValue entries named PrinterProperties. Essential parameters must be enclosed in parentheses after the function or procedure names. In the simplest scenario, a table control element is linked to a database using the autopilot form, which links all columns with the relevant database fields in accordance with the user specifications. The example first creates a text field which supports the com.sun.star.text.textfield.PageNumber service. The CellAddress structure provides the following values: The cell contents in the target range are always overwritten by the moveRange method. For example, most of the page properties described in #Spreadsheets can therefore be used not only in LibreOffice Calc, but also in LibreOffice Writer. MsgBox displays a basic information box, which can have one or more buttons. These include not only single-dimensional strings, but also two-dimensional fields. If the user changes one of the attributes of a style, then LibreOffice automatically adjusts all document sections depending on the attribute. A table is usually accessed in LibreOffice through the ResultSet object. Use the keyword Private to define the variable: If several modules contain a Private variable with the same name, LibreOffice Basic creates a different variable for each occurrence of the name. You can copy or move subs, functions, modules and libraries from one file to another by using the Macro dialog. 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. It accesses the array of models using the GetGroupByName method (rather than the GetByName method to determine simple models). VBA: Unlike VBA, where you can only dimension dynamic arrays by using Dim MyArray(), LibreOffice Basic lets you change both static and dynamic arrays using ReDim. Line charts provide the following properties: Area charts (com.sun.star.chart.AreaDiagram service) support two X-axes, two Y-axes and one Z-axis. At this point, only some of the abstract aspects of objects, for which the LibreOffice API provides some central interfaces, are discussed. To define the cell range that you want to insert, use the com.sun.star.table.CellRangeAddress structure. It supports the createTextCursor interface for creating an associated TextCursor object. A currency variable can store any value between -922337203685477.5808 and +922337203685477.5807 and takes up to eight bytes of memory. The. The following example inserts text in a rectangle and formats the font com.sun.star.style.CharacterProperties service. When using the CompatibilityMode ( true ) function, LibreOffice Basic behaves like VBA and the Dir function, using parameter 16, returns sub-directories and standard files. Variables that are declared in a function or a procedure are called local variables: Local variables only remain valid as long as the function or the procedure is executing, and then are reset to zero. If you start the macro from the IDE, ThisComponent will still find and return your document. The com.sun.star.awt.UnoControlEdit service forms the basis for text fields. If you click a button that has this property set to the value of 1, the dialog is closed, and the Execute method of the dialog returns the value 1 (dialog sequence has been ended correctly). The code in the following example moves an entry from the left to the right list box of a dialog. can define the digits after the decimal point in an expression: In the same way, zeros can be added in front of a number to achieve the desired length: A , represents the character that the operating system uses for a thousands separator, and the # stands for a digit or place that is only displayed if it is required by the input string. This is a transfer channel which permits direct communication with the database. As a parameter, this takes the name of the property and returns a constant that provides information about the origin of the formatting. Use thereof is explained in our trademark policy (see Project:Copyrights for details). Any modifications made to the data within the spreadsheet will also be reflected in the assigned chart. The location of individual cells in a cell range can be determined using the getCellByPosition method, where the coordinates of the top left cell in the cell range is (0, 0). Its argument specifies the value that will be returned by execute method. Values for the Array fields can be stored like this: Accessing values in an array works like this: And example containing all steps that show real array usage: A variable in LibreOffice Basic has a limited life span and a limited scope from which it can be read and used in other program fragments. The following sections describe the main formatting options for spreadsheet pages. A control element of a form has three aspects: The models of the control elements of a form are available through the GetByName method of the Object form: The example determines the model of the MyListBox control element, which is located in the first form of the text document currently open. createUnoService creates an object which can be used universally. In the simplest scenario, these are the X and Y-axes. 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. 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. LibreOffice therefore compresses the files and saves them as a ZIP file. To make the definition available to other modules, add the Public keyword. If the bitmap is already available in LibreOffice, you just need to specify its name in the FillBitMapName property and its display style (simple, tiled, or elongated) in the FillBitmapMode property (default values in accordance with com.sun.star.drawing.BitmapMode). VBA: The flags used in VBA for querying the concealed, system file,archived and volume name file properties are not supported in LibreOffice Basic because these are Windows-specific and are not or are only partially available on other operating systems. If it does, the method determines a corresponding object reference by using the getByName method and then saves the reference in a variable in Sheet. The following example moves the B2:C3 range so that the range starts at position A6: In addition to the CellRangeAdress structure, the moveRange method expects a com.sun.star.table.CellAddress structure to define the origin of the move's target region. An example of the use of XNameAccess is provided by the sheets object of a spreadsheet. Note: The text frame is therefore inserted directly in the text flow and behaves like a character. 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. In LibreOffice, these properties are defined using a page style which in turn is linked to the associated document. The Select command is not restricted to simple 1:1 assignments you can also specify comparison operators or lists of expressions in a Case branch. This is probably not what you want. Once the writing process has been completed, the file must be closed using a Close call: Again here, the file handle should be specified. The structure is further complicated by tables. en If a corresponding model is found, then a reference to this is saved in the Ctl variable and the search is terminated. A table consists of individual rows. A dialog can contain any number of control elements. The following values are available: The following example creates a circular slice with a 70 degree angle (produced from difference between start angle of 20 degrees and end angle of 90 degrees). In VBA, the function also returns the names of the standard files so that further checking is needed to retrieve the directories only. The following example uses the hasByName method to check if a page called MyPage exists. 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. Note: VBA: The ResultSet object from SDBC is comparable with the Recordset object from DAO and ADO, since this also provides iterative access to a database. Information about how to create, open, save and print documents is described in #Working with Documents, because it can be used not only for text documents, but also for other types of documents. In LibreOffice Basic, this is irrelevant. The 0 (zero) used as the second parameter in the Dir function ensures that Dir only returns the names of files; directories are ignored. To define your own color gradient, you need to complete a com.sun.star.awt.Gradient structure to assign the FillGradient property. The functions resident in the old Application object for controlling the on-screen depiction of LibreOffice (for example, FullScreen, FunctionBarVisible, Height, Width, Top, Visible) are no longer used. Note: The preceding Document object could, for example, provide a Save method, which can be called as follows: Methods, just like functions, may contain parameters and return values. With the value, LibreOffice Basic ignores the part of the exponent after the decimal point and interprets the expression as. Some interfaces of LibreOffice can be found in many parts of the LibreOffice API. Correct handling of error situations is one of the most time-consuming tasks of programming. Logical operators allow you to do operations on elements according to the rules of Boolean algebra. Some UNO services in turn support other services so that, through one object, you are provided with a whole range of services. For more information and examples of this service, see #Formatting Spreadsheet Documents. Text frame objects provide a range of properties with which the position and behavior of the frame can be influenced. If you use the CompatibilityMode ( true ) function, LibreOffice Basic will behave like VBA. The com.sun.star.presentation.PresentationDocument service, responsible for presentation documents, also provides the complete com.sun.star.drawing.DrawingDocument service. If a cell contains a numerical value, then the example changes the formatting correspondingly. LibreOffice provides various functions that allow you to change the justification of a text in a table cell. You must use whole numbers that are preceded by &O. Boolean variables can only contain one of two values: True or False. Each paragraph is recorded in its own HTML element

for this purpose. 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 com.sun.star.style.CharacterProperties service does not provide any interfaces, but instead offers a range of properties through which character properties can be defined and called. However, this may have fatal consequences. The insertByName line inserts the NewStyle style under the name of the same name in the ParagraphStyles object. The X-axis points in reverse direction from right to left. Issue 31001 Issue 54049 Issue 91121 Issue 107277 are still not corrected. The most important interface of the StarDesktop is com.sun.star.frame.XComponentLoader. 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. 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 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.
