libreoffice basic programming guide pdf
If this is not the case, it must be determined using the preceding code. This call is only available provided that the data has not be re-written into the database using updateRow(). The following example lists the most important syntax variants: Now consider a misleading (advanced) example, and a common error: The statement (Var = 8) evaluates to TRUE if Var is 8, and FALSE otherwise. Issue 31001 Issue 54049 Issue 91121 Issue 107277 are still not corrected. There are numerous options for formatting cells, such as specifying the font type and size for text. All the named objects return an object that supports the com.sun.star.sheet.HeaderFooterContent service. LibreOffice recognizes four main types of formatting for a fill area. The expression, is interpreted as 1.43 minus 2, which corresponds to the value -0.57. The example uses the supportsService method to check whether the TextElement is a paragraph or a table. Therefore, before copying the content from B to A, B has to be converted into A's internal format. If it finds the search term, it takes the part before the expression and writes it to the Result return buffer. That covers almost everything Microsoft Office includes. In addition to the Name property used in the example, the com.sun.star.sdb.QueryDefinition provides a whole range of other properties. (When listing the service name of a text field, uppercase and lowercase characters should be used in LibreOffice Basic, as in the previous example.). No assurances are, however, provided for whether these can also be used by the object in question. The Format Cells dialog in LibreOffice Calc provides an overview of the different formatting options for cells. The following example checks whether the date saved in MyDate is in the year 2003. Context-dependent objects are usually created by means of an object method, on which the object depends. The insertNewByIndex method is obtained from the com.sun.star.drawing.XDrawPages interface. If the corresponding sheet does not exist, it is created by the createInstance call and inserted in the spreadsheet document by the insertByName method. The previous section has already discussed a whole range of options for editing text documents, focusing on the com.sun.star.text.TextPortion and com.sun.star.text.Paragraph services, which grant access to paragraph portions as well as paragraphs. Creating the Macro. Establishing whether a section of a document has been directly or indirectly formatted is not easy. 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). There is no direct counterpart in LibreOffice Basic for the Characters, Sentences and Words lists provided in VBA. The code is first checked for obvious errors and then executed line by line. The following example shows a procedure which terminates implementation when the ErrorOccured variable has the value True. The On Error Goto 0 call at the end of the code resets the status information of the error (the error code in the Err system variables) so that an error occurring at a later date can be clearly recognized. The LibreOffice API provides you with a whole range of objects with which you can create, open and modify Office documents. A VBA object is always assigned to precisely one single class. All the options specified here are based on the user interface from LibreOffice. Once this is done, the Sheets collection is assigned to my_sheets object to access all the Text frame objects provide a range of properties with which the position and behavior of the frame can be influenced. In the previous example, if the UserInput variable contains a valid numerical value, then this is assigned to the ValidInput variable. The com.sun.star.view.XPrintable interface, which contains the methods for printing documents. WebHome; About; Fishing Blogs; Accommodations Taking a fishing trip through Canada or attending championships and tournaments demands accommodation and attractions that suit an exciting fishing experience. Since the drivers are based on UNO components, other drivers can be developed and therefore open up new data sources. The Format function formats numbers as a string. They may essentially consist of standard text, but can be placed at any position on a page and are not included in the text flow. java and OS/2 (TM). More information about working with styles can be found in the '''#Default values for character and paragraph properties''' section in #Text Documents. The declaration. If a ResultSet is a SCROLL_INSENSITIVE or SCROLL_SENSITIVE type, it supports a whole range of methods for navigation in the stock of data. 
The Diagram object provides the following properties to access the grids: The grid object is based on the com.sun.star.chart.ChartGrid service, which in turn supports the line properties of the com.sun.star.drawing.LineStyle support service (refer to #Drawings and Presentations). The associated constants are defined in the com.sun.star.sheet.GeneralFunction enumeration. The copyRange method functions in the same way as the moveRange method, except that copyRange inserts a copy of the cell range instead of moving it. The return value can be overwritten several times within the function. WebThe SDK provides a rich set of examples in different programming languages (Java, Python, C++, LibreOffice 7.4 Basic, OLE) to illustrate the use of the API and The com.sun.star.sheet.TablePageStyle service is only used in LibreOffice Calc page styles and allows cell ranges that you want printed to be centered on the page. Data can either be displayed as 2D or 3D graphics, and the appearance of the chart elements can be individually adapted in a way similar to the process used for drawing elements. More information about working with these buttons is discussed in #Control Elements in Detail. Here are a few examples of Variant variables: The variables declared in the previous example can even be used for different variable types in the same program. When the function is called with the base condition, a result is returned. Note: In the following example, the loop is terminated during the fifth pass: The For EachNext loop variation in VBA is supported in LibreOffice Basic. Instead use the LibreOffice Basic MouseUp event for the click event and imitate the Doubleclick event by changing the application logic. 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. Instead, you need to create an array of the points, package this array in a second array (using the Array(Coordinates()) call), and then assign this array to the polygon. 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. The runtime library from LibreOffice Basic provides several fundamental functions for these tasks. Topics Include The WithEnd With bracketing statements provide an alternative to writing out all the qualifiers, every time and some of the qualifiers in the API can be quite long. LibreOffice Basic provides two methods for inserting comments in the program code: A comment usually includes all characters up to the end of the line. When specifying a service name, it is only the module name which is of any importance because this must be also listed in the name. This event is initiated by either a key-press or a mouse button. VBA: LibreOffice Basic does not provide code completion. The letter "e" can be lowercase or uppercase with or without a plus sign (+) as a prefix. libreoffice 6 0 6 2 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. A spreadsheet document provides properties and methods for formatting cells and pages. A long integer variable can take up to four bytes of memory. The program code for defining the hatch is very similar to the code for color gradients. 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. While the declaration MyInteger(3) creates three integer values in VBA with the indexes 1 to 3, the same declaration in LibreOffice Basic creates four integer values with the indexes 1 to 4. The LibreOffice API provides two options for creating objects. Webdownload and install Openoffice Org Basic Programming Guide Pdf Pdf as a result simple! Before the corresponding call can be made, the polygon must be inserted into the document. Functions and procedures can only be called up if all the necessary parameters are passed during the call. 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. In LibreOffice, the fields are administered using an object-oriented concept. This example removes the B2:C3 cell range from the sheet and then shifts the underlying cells up by two rows. The symbol defined in the corresponding country-specific settings must be used as the decimal point symbol. When the dimensions of the data field are changed, all contents are lost. For example, the aforementioned object, which is based on the com.sun.star.frame.Desktop service, can also include other services for loading documents and for ending the program. Whereas the dialog functions are available in all LibreOffice documents, the full scope of the form functions are only available in text and spreadsheets. When Var is 0, there is a match. When LibreOffice Basic encounters an incorrectly defined variable type in a particular context, an error message is generated. Figure 1: Draw main window Draw main window Workspace The large area in the center of the Draw main window ( Figure 1) is the Workspace, where drawings are created. The drawing object can, for example, be created as follows using a spreadsheet object: A paragraph template in a text document is created in the same way: The XNameAccess and XNameContainer interfaces are used in objects that contain subordinate objects, which can be addressed using a natural language name. Once the method has been completed, Save saves a return value in the Ok variable. 3D charts usually also have a floor. A . The XNameContainer interface takes on the insertion, deletion and modification of subordinate elements in a basic object. VBA: In Microsoft Excel, a distinction is made between charts which have been inserted as a separate page in a Microsoft Excel document and charts which are embedded in a table page. If the file name contains sub-directories, then these are separated by a single forward slash, not with a backslash usually used under Windows. The text frame created in this way can then be inserted in the document using the insertTextContent method of the Text object. The ResultSet object provides Update methods for modifying values, which are structured in the same way as the get methods for retrieving values. 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. Remember to use the object returned from opening the document instead of ThisComponent. In this case, the syntax of the function is: In the previous examples, InStr ignores uppercase and lowercase characters. The following sections present the central functions of the runtime library: In many situations, circumstances arise in which a variable of one type has to be changed into a variable of another type. The structure for hatches has the following properties: The following example demonstrates the use of a hatch structure: This code creates a simple hatch structure (HatchStyle = SINGLE) whose lines are rotated 45 degrees (Angle). The loop is terminated as soon as the hasMoreElements method returns the False value, signaling that the end of the text has been reached. If a number is not provided, 0 is displayed in its place. This service provides the following properties: When you format sheets, you can define whether page elements are visible. One can be found in the createUnoService function mentioned at the start of this chapter. The LibreOffice API (Application Programming Interface): Permits access to LibreOffice documents and allows these to be created, saved, modified, and printed. TRUE is -1 and FALSE is 0. A table consists of individual rows. In LibreOffice Basic, this is irrelevant. Example declaration of a string variable: Note: The document object of a spreadsheet is based on the com.sun.star.sheet.SpreadsheetDocument service. This is because a paragraph in turn consists of individual sub-objects. Before you can create the dialog, you must ensure that the library it uses (in this example, the Standard library) is loaded. Jumping directly to a general program procedure from a macro can result in unclear code. It displays the names in a message box. Templates for formatting characters, paragraphs, and pages, Non-text elements such as tables, graphics and drawing objects, A period within a search expression stands for any character. When you port a VBA application to LibreOffice Basic, you must change any duplicate variable names. The real API call is: Sheet.getColumns.getByIndex(1). Give your desired name in the macro name box and click New. As of LibreOffice Version 3.3, this status does not show in the GUI, nor is there any GUI way to re-enable the feature. The Dialog Editor: Creates personal dialog windows and provides scope for the adding of control elements and event handlers. The False parameter in the previous function call specifies whether the area passed over with the cursor movement is highlighted. Here are the central methods that the com.sun.star.text.TextCursor service provides for navigation: The text is divided into sentences on the basis of sentence symbols. In this example, the counter begins at 10 and is reduced by 1 at the end of each pass until the counter is 1. As can be seen in the example from the previous section, LibreOffice provides a getString method for accessing table contents. The main property for single-color fills is: To use the fill mode, you must the FillStyle property to the SOLID fill mode. It could be for example, A247. This example shows how a text can be searched for the word "turnover" and the results formatted in bold type. You can page through and search in the selected tables and queries, as well as change data records and insert new data records. To convert local file names into a URL, LibreOffice provides the ConvertToUrl function. The formatting options that are available depend on the type of drawing object. Every chart has a background area. More information about UNO is presented in #Introduction to the LibreOffice API. For example, the following line declares an array with four integer variables: In the previous examples, the index for the array always begins with the standard start value of zero. The letter A stands for the column and the number 1 for the row. These determine the procedure LibreOffice uses when saving a document.
