libreoffice basic programming guide pdf

You can, for example, highlight a certain word within a text using bold type or center a line. Extensive examples are provided to help you quickly develop your own LibreOffice Basic programs. The following example inserts text in a rectangle and formats the font com.sun.star.style.CharacterProperties service. In the simplest scenario, these are the X and Y-axes. Furthermore, the following methods are provided through the view object of the list box: LibreOffice forms can be directly linked to a database. These commands stop the procedure or function and return the program to the point at which the procedure or function was called up. The example first creates a list containing all rows using a Table.getRows call.

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 properties of this service are: The following example creates a rectangle with a shadow that is vertically and horizontally offset from the rectangle by 2 millimeters. The following example shows how to create a chart assigned to some cell ranges within a spreadsheet document: Although the code used in the example may appear to be complex, the central processes are limited to three lines. The best way to learn Python is a simple text editor with syntax highlighting. documents = StarDesktop.getComponents () enumeration = documents.createEnumeration () Do While enumeration.hasMoreElements () doc = enumeration.nextElement () window = doc.CurrentController.Frame.ComponentWindow window.setFocus () REM Sleep 1.5 seconds Wait 1500 Loop. The number of elements in an array is not affected if you use Option Base 1, only the start index changes. Note: 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. LibreOffice provides various ways of establishing database connections. A number of UNO objects support the supportsService method, with which you can establish whether an object supports a particular service. The type declaration symbol for a long integer is &. Basic can handle both methods like a property Name. English documentation | LibreOffice Documentation - LibreOffice User Guides en / English documentation English documentation Getting Started Books Buy a printed copy Download PDF Guide Source Files Website Buy a printed copy Download PDF Download Source Files Read in your browser Buy a printed copy Download PDF Download Source Files 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 Execute method of the dialog returns the value 0, which is the same as when you click Cancel. ThisComponent returns the currently active document. The Chart object provides the property Area to format the background: The background of a chart covers its complete area, including the area under the title, subtitle and legend. For Windows the recursion level is 5800. If the document has already been assigned a URL and is not a read-only document, it is saved under the existing URL. Some UNO services in turn support other services so that, through one object, you are provided with a whole range of services. 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 code determines the object for the MyButton control element and then initializes the Ctl object variable with a reference to the element. Since the header and footer lines are defined as part of the page templates of LibreOffice, this is initially established using the list of all PageStyles. This example shows how a text can be searched for the word "turnover" and the results formatted in bold type. The execute method of the dialog returns the value 0, which is the same as when you click Cancel. The FileProperties array has two elements, one for each option used. To get the most out of this book, you should be familiar with other programming languages. Since LibreOffice Basic uses the country-specific settings of the operating system when converting a string into a date value, the expression shown previously only functions correctly if the country-specific settings match the string expression. As Basic makes automatic type conversions, there is usually no problems using a constant in an expression. Basic can handle both methods like a property Name. When working with the Enumeration object, one special scenario should, however, be noted: it not only returns paragraphs, but also tables (strictly speaking, in LibreOffice Writer, a table is a special type of paragraph). Text frames are considered to be TextContent objects, just like tables and graphs. The formatting options that are available depend on the type of drawing object. A single variable can take up to four bytes of memory. The Exit For instruction allows you to exit a For loop prematurely. LibreOffice Basic provides the MsgBox and InputBox functions for basic user communication. The As keyword syntax, and the fact that a comma is not used, goes back to the roots of the Basic language. When you click a button that has this property set to the value of 0, the dialog remains unaffected. (In the following examples, A > 10 represents any condition): As in the ForNext loop, the DoLoop also provides a terminate command. 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. Among the most useful are: LibreOffice Basic understands common mathematical, logical, and comparison operators. The easiest way is to assign the format properties directly to the text sequence. The paragraph properties are available through the com.sun.star.style.ParagraphProperties service. There is no type declaration symbol for Boolean variables. A default value which can be added within the input area. These are neither named nor indexed and there is therefore no possible way of directly accessing individual paragraphs. The example first creates a text field which supports the com.sun.star.text.textfield.PageNumber service. The starting point for establishing the text fields present is the TextFields list of the document object. LibreOffice Basic lets you use whole numbered hexadecimal values, so long as they are preceded by &H. LibreOffice Basic also understands the octal system (base 8 system), which uses the numbers 0 to 7. 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. Note: For example, during a replacement process, case sensitivity can also be activated and deactivated, and similarity searches can be performed. If you want to format the individual objects of a group, apply the formatting before you add them to the group. In place of the $ placeholder, the Format function displays the relevant currency symbol defined by the system (this example assumes a European locale has been defined): The format instructions used in VBA for formatting date and time details can also be used: LibreOffice Basic provides the Date data type, which saves the date and time details in binary format. Warning: It displays the names in a message box. It provides the functions for the frame object of LibreOffice, under which all document windows are classified. After modification, the values must be transferred into the database using the updateRow()method. The following example shows a double loop which passes over all paragraphs of a text document and the paragraph portions they contain and applies the replacement processes from the previous example: The example runs through a text document in a double loop. Cells cannot be formatted by column in LibreOffice Basic. If you want to specify the type of a data, use a typed variable, not a constant. The following focus events are available: The Event objects for the focus events are structured as follows: In addition to the preceding events, which are supported by all control elements, there are also some control element-specific events that are only defined for certain control elements. When you port a VBA application to LibreOffice Basic, you must change any duplicate variable names. The XNameContainer interface takes on the insertion, deletion and modification of subordinate elements in a basic object. The first central line creates the Doc document variable, which references the current spreadsheet document (Doc line = StarDesktop.CurrentComponent). LibreOffice Basic provides four functions that return partial strings, plus a length function: Unlike array subscripts, character positions in a string start with 1. 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. Some drivers access file-based databases and take the data directly from them. The formatting properties can be found in each object (Paragraph, TextCursor, and so on) and can be applied directly. The following example uses the hasByName method to check if a sheet called MySheet exists. This is probably not what you want. The expression, is interpreted as 1.43 minus 2, which corresponds to the value -0.57. TRUE is -1 and FALSE is 0. Import and export of spreadsheets in multiple formats, including HTML, CSV, PDF, and Java LibreOffice Programming. A table consists of individual rows. Most template types Draw templates are the exception have an automatic-update feature. VBA: In VBA, the MkDir and RmDir functions only relate to the current directory. The com.sun.star.awt.UnoControlEdit service forms the basis for text fields. These event types can be divided into four groups: When you work with events, make sure that you create the associated dialog in the LibreOffice development environment and that it contains the required control elements or documents (if you apply the events to a form). By convention, the symbolic names given below are written in UPPERCASE, to mark them as predefined, rather than user-defined. 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. StarOffice 5: The database is actually accessed in LibreOffice through a ResultSet object. This code works only if the macro is started from the document itself! libreoffice basic programming guide pdf By July 27, 2021 OpenOffice Basic . A, on the other hand, is a string, and the computer saves a one- or two-byte long value for each character (each number). These are useful if no cells have been merged in the table. The wall is set to be blue. It contains the following properties: The following example uses the KeyCode property to establish if the Enter key, the Tab key, or one of the other control keys has been pressed. The following properties are defined in the com.sun.star.style.PageProperties service: The following example creates a header in the "Default" page style for text documents and adds the text "Just a Test" to the header. For detailed information check out our wiki page. If you are not sure of the form of a control element, you can use the option for searching through all forms for the control element required: The example uses the HasByName method to check all forms of a text document to determine whether they contain a control element model called MyListBox. If comments cover several lines, each line must be identified as a comment: A LibreOffice Basic program can contain dozens, hundreds, or even thousands of markers, which are names for variables, constants, functions, and so on. Note: The method provides the result in the form of a string. The following call, for example, determines whether the TextElement object supports the com.sun.star.text.Paragraph service. Alternatively, you can use the keyboard shortcut Ctrl + O within LibreOffice Draw and select the document you want to open. It is described in the chapter Apache OpenOffice Basic of the Developer's Guide. LibreOffice Basic saves strings as string variables in Unicode. While this dialog is open, the program remains in the Execute call. 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. check the "Macro" chapters in LibreOffice and Calc guides (1.1, ch. Any number of documents can be opened in this way in LibreOffice Basic and then edited using the returned document objects. At the end, the drawing object is assigned to a page using a Page.add call. Note: You can access the individual sheets of a spreadsheet document through the Sheets list. You can assign a date to a date variable through the assignment of a simple string: This assignment can function properly because LibreOffice Basic automatically converts the date value defined as a string into a date variable. Since the points of a polygon are defined as absolute values, you do not need to specify the size or the start position of a polygon. The following call also specifies the True parameter for the document object when requesting the Save method. The type declaration symbol for an integer variable is %. The code is first checked for obvious errors and then executed line by line. Then it iterates through the entire text, sentence by sentence, and highlights each of the first words and formats this in bold. An A stands for the decimal number 10, while the letter F represents the decimal number 15. You can design each page separately. 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. When variable I equals 10, the loop stops. Text fields can be inserted in a text document using the same methods as those used for other TextContent objects: The example inserts a text field with the current date at the start of the current text document. The mechanisms explained there are identical to those for forms. 257x267px The 0 character within the template ensures that a number is always placed at the corresponding point. The properties of the text frame objects are set to the starting values required. The CellAddress structure provides the following values: The cell contents in the target range are always overwritten by the moveRange method. The main property for single-color fills is: To use the fill mode, you must the FillStyle property to the SOLID fill mode. In addition to these "real" properties, there are also properties in LibreOffice Basic which consist of two methods at the UNO level. Instead, the DoLoop is executed until a certain condition is met. The simplest variant is a single-color fill. The TextCursor object in LibreOffice Basic acts independently from the visible cursor in a text document. The elements in getByIndex however are numbered beginning with 0. 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. The following properties can be specified: The following example shows how the number of pages can be inserted into the footer of a document. Standard file names using this system begin with the prefix file:/// followed by the local path.
