Subs and functions are always contained in modules. Note: It uses not only the Doc document object but also the DocCrl document controller object which makes reference to the current document window. Most charts in LibreOffice can also be displayed with 3D graphics. To determine a special control element, all drawing elements of the drawing level must be searched through. Charts are not treated as independent documents in LibreOffice, but as objects that are embedded in an existing document. 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. If nothing is assigned, the function returns a zero value (number 0 for numerical values and a blank for strings). LibreOffice does not limit the number of pages in a drawing document. There is no type declaration symbol for date variables. It accesses the array of models using the GetGroupByName method (rather than the GetByName method to determine simple models). 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. Whereas the Document.Tables.Add method takes on the task of creating and setting the table in VBA, this is created in LibreOffice Basic in accordance with the previous example using createInstance, initialized, and inserted in the document through insertTextContent. The most common branching statement is the If statement as shown in the following example: The B = 2 assignment only occurs when value of variable A is greater than three. Direct formatting always takes priority over indirect formatting. The color gradient is depicted using a hundred graduated individual colors (StepCount). The ForNext loop has a fixed number of passes. The headers and footers of a document form part of the page properties and are defined using the com.sun.star.style.PageProperties service. Buy a printed copy. To display all information available from an object and link to the corresponding API documentation, use instead the Development Tools built into LibreOffice or MRI extension. Write it before the inner name, and separate it by a period: Since containers may hold other containers, you may need more than one qualifier. VBA: In VBA, the formatting properties of an object are usually spread over a range of sub-objects (for example, Range.Font, Range.Borders, Range.Shading, Range.ParagraphFormat). In this case, the frame object of the window should contain an explicit name. This ensures that at any one time, only one option button is set. However, this character set does not include a range of special characters used in Europe, such as , , and , as well as other character formats, such as the Cyrillic alphabet. For this purpose, the com.sun.star.sheet.TablePageStyle service provides the following properties: Whereas the previous section described the main structure of spreadsheet documents, this section describes the services that allow you to easily access individual cells or cell ranges. 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. The LibreOffice Developer's Guide describes the LibreOffice API in more detail than this guide, but is primarily intended for Java and C++ programmers. The main properties of this service are described in the following sections. The Exit For instruction allows you to exit a For loop prematurely. 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. Microsoft based its Windows product on the American National Standards Institute (ANSI) character set, which was gradually extended to include characters that are missing from the ASCII character set. The minimum value of the Y-axis is fixed to 0 and the maximum value is fixed to 100 so that the resolution of the chart is retained even if the values are changed. You can copy or move subs, functions, modules and libraries from one file to another by using the Macro dialog. For example, support for the ChDir, ChDrive and CurDir functions is not provided. 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 gradient starts with red (StartColor) in the top left corner, and extends at a 45 degree angle (Angle) to green (EndColor) in the bottom right corner. The ASCII character set is a set of codes that represent numbers, characters, and special symbols by one byte. This is not the case for new documents. The first character of a marker must be a letter or an underscore. storeAsURL provides the following options: The following example shows how the Overwrite option can be used in conjunction with storeAsURL: The example then saves Doc under the specified file name if a file already exists under the name. The following example lists the names of data source queries can be established in a message box. Note: If the cursor of LibreOffice is in a cell, then the name of that cell can be seen in the status bar. These include tables, drawings, text fields and directories. The Dialog Editor: Creates personal dialog windows and provides scope for the adding of control elements and event handlers. As in the old API from LibreOffice, searching and replacing text in the new API is also performed using the document object. For example, the TextCursor in the following example. LibreOffice Basic recognizes the following mouse events: Note: 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 com.sun.star.presentation.PresentationDocument service, responsible for presentation documents, also provides the complete com.sun.star.drawing.DrawingDocument service. The core of a text document consists of a sequence of paragraphs. When you port a VBA application to LibreOffice Basic, you must change any duplicate variable names. The createInstance method, which is defined in the XMultiServiceFactory interface, is used in particular in the document objects. In this example, the counter begins at 10 and is reduced by 1 at the end of each pass until the counter is 1. com.sun.star.awt.UnoControlTimeField, A numeric field makes it possible to enter, display and edit formatted numeric values. Alternatively, you can use the keyboard shortcut Ctrl + O within LibreOffice Draw and select the document you want to open. An event handler runs a predefined procedure when a particular action occurs. 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). Basic Guide - Computer Science and Engineering | Engineering com.sun.star.awt.UnoControlCurrencyField. The second section addresses more complex editing functions, such as grouping, rotating, and scaling objects. The dialog can be reached using Event.Source.Context. The start index of a data field usually begins with the value 0. Although you can use the + operator to concatenate strings, the Basic interpreter can become confused when concatenating a number to a string. This supports the com.sun.star.document.OfficeDocument service, which in turn provides two central interfaces: LibreOffice documents are saved directly through the document object. A single key action on a modification key, such as the Shift key or the Alt key does not create an independent event. Write the qualifiers in order, from outer to inner: These names may also be described as, "concatenated with the dot-operator ('.')". To continue a program without an error message when an error occurs, use the following format: Use the On Error Resume Next command with caution as its effect is global. The associated constants are defined in the com.sun.star.sheet.GeneralFunction enumeration. The bookmarks of a text are accessed through a list called Bookmarks. 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 TextCursor object in LibreOffice, for example, provides methods for navigating and changing text which are included in the Range object in VBA (for example, MoveStart, MoveEnd, InsertBefore, InsertAfter). In LibreOffice, these properties are defined using a page style which in turn is linked to the associated document. 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. Note: This event is also used for notifying requests for a popup context menu on the control. The loadComponentFromURL function introduced in the previous section returns a document object. If the user changes one of the attributes of a style, then LibreOffice automatically adjusts all document sections depending on the attribute. In terms of functionality, OptimalWidth is more of a method than a property. Similarly, if you set this value to zero for a control element, the element is displayed on all the tab pages in a dialog. The following is an example of a search and replace process: This example uses the first page of the document to create a ReplaceDescriptor and then applies this to all pages in a loop. In the present version of LibreOffice, a visible StarDesktop is no longer used. Note: Buy a printed copy. The objects are accessed as follows in text documents: The GetByIndex method returns the form with the index number 0. The following example inserts text in a rectangle and formats the font com.sun.star.style.CharacterProperties service. The text frame is created using the createInstance method of the document object. 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. As the number of these words is initially unknown, you need to be able to subsequently change the field limits. Content on this page is licensed under the Public Documentation License (PDL). A complete list of all text fields is provided in the API reference in the com.sun.star.text.textfield module. Python libraries help organize modules in order to prevent module name collisions. Anyone who has already worked with these languages can quickly become accustomed to LibreOffice Basic. Do not specify the constant type in the declaration: it will be silently ignored. They are listed in the source text without a comma separating the thousand figure: The numbers can be preceded by both a plus (+) or minus (-) sign (with or without a space in between): When you type a decimal number, use a period (.) If a style in the template has been changed, and you open a document created with that template, you will see a message asking whether to update the styles in the document. Any number of documents can be opened in this way in LibreOffice Basic and then edited using the returned document objects. However, unlike the old Application object, StarDesktop is primarily responsible for opening new documents. A Boolean value is saved internally as a two-byte integer value, where 0 corresponds to the False and any other value to True. Note: These are neither named nor indexed and there is therefore no possible way of directly accessing individual paragraphs. The properties are provided by the com.sun.star.util.SearchDescriptor service: The LibreOffice SearchSimilarity (or fuzzy match) function is also available in LibreOffice Basic. Since control element forms within the documents are administered like a special drawing element, there is also a, This page was last edited 13:55:11, 2022-12-07 by, Please note that all contributions to The Document Foundation Wiki are considered to be released under the. 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. It only allows iteration to be applied forward, and for values to be interrogated. The example Dim MyIntArray(5, 5) As Integer defines an integer array with two dimensions, each with 6 indexes (can be addressed through the indexes 0 to 5). An example of the use of XNameAccess is provided by the sheets object of a spreadsheet. To simplify access to the tables, LibreOffice, however, provides some methods which operate using columns. To prevent errors caused by an implicit declaration of variables, LibreOffice Basic provides a switch called: This must be listed in the first program line of each module and ensures that an error message is issued if one of the variables used is not declared. These commands stop the procedure or function and return the program to the point at which the procedure or function was called up. If the True parameter is passed here, then insertControlCharacter replaces the current text. The top left cell is usually called A1 and the bottom right row is usually called Xn, where X stands for the letters of the top column and n for the numbers of the last row. However, this is not sufficient for many problems. Example declaration of a Boolean variable: Date variables can contain date and time values. If the activation sequence is interrupted by another control element, then LibreOffice automatically starts with a new control element group that can be activated regardless of the first group of control elements. LibreOffice Developer's Guide: Chapter 11 - LibreOffice Basic < Documentation | DevGuide Contents 1 First Steps with LibreOffice Basic 1.1 Step By Step Tutorial 1.2 Creating a Module in a Standard Library 1.3 Writing and Debugging a Basic UNO program 1.4 Calling a Sub from the User Interface 1.5 Creating Dialogs 1.6 Adding Event Handlers All formatting options for individual characters and paragraphs are therefore automatically available. Methods can be understood as functions that relate directly to an object and through which this object is called. When using the CompatibilityMode ( true ) function, LibreOffice Basic behaves like VBA and the Dir function, using parameter 16, returns sub-directories and standard files. The LibreOffice API provides two options for creating objects. For Solaris and Linux, an evaluation of the stacksize is performed and the recursion level is calculated. (For Writer documents only, you can use the Template Changer extension to set this feature again.). LibreOffice notes the SQL commands of queries so that they are available at all times. A dialog can contain any number of control elements. Download PDF. Like bubbles, the variables gradually migrate to the right position. Working with LibreOffice Basic Their respective logos and icons are also subject to international copyright laws. Example declarations for single variables: Double variables can store any positive or negative floating point numbers between 1.79769313486232 x 10308 and 4.94065645841247 x 10-324. Function calls, mathematical expressions, and other linguistic elements, such as function and loop headers, must be completed on the same line that they begin on. The data field must provide a PropertyValue structure for each option in which the name of the option is saved as a string as well as the associated value. 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. In the preceding example, you can also assign the Step value of 0 to the dividing line as well as the Cancel, Prev, Next, and Done buttons to display these elements on all pages. The getByIndex method returns a row object, which supports the com.sun.star.text.TextTableRow service. VBA: The path specifications listed in Dir may use the * and? However, this may have fatal consequences. 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. 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 These services relate to individual characters and paragraphs and are described in detail in #Text Documents. A date / time field (com.sun.star.text.textfield.DateTime) represents the current date or the current time. The counting variable of the loop therefore runs from 0 to getCount()-1.
