In addition to providing several interfaces for editing the content, this service provides the following properties: A sheet provides methods getName and setName to read and modify its name. Note: This chapter describes how to control the relevant services, methods and properties of spreadsheet documents: The first section addresses the basic structure of spreadsheet documents and shows you how to access and to edit the contents of individual cells. Before you can create the dialog, you must ensure that the library it uses (in this example, the Standard library) is loaded. If an error is made during the modifications, this can be undone using the cancelRowUpdates()method. The False parameter in the previous function call specifies whether the area passed over with the cursor movement is highlighted. 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. It focuses on paragraphs, paragraph portions and their formatting. For more information and examples of this service, see #Formatting Spreadsheet Documents. The following example is an algorithm that uses two loops to sort a list by names. The Format Cells dialog in LibreOffice Calc provides an overview of the different formatting options for cells. The declaration can only be made using the supplement As Boolean. The modules are of no other functional importance for LibreOffice Basic programmers. There are passed through in turn in a loop. If it finds the search term, it takes the part before the expression and writes it to the Result return buffer. In the latter examples, the code will be executed at least once. Strictly speaking, a PolyPolygon is not a simple polygon but a multiple polygon. This is an instance of the example function described in #Search and Replace. The SetAttr function permits the properties of a file to be changed. The following path references the test.odt file in the doc directory on the C: drive: file:///C:/doc/test.odt This example shows how you may define and use a struct, and how to reference the items within it, both with and without With. 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 five most important placeholders within a template are the zero (0), pound sign (#), period (. 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. VBA: LibreOffice Basic does not provide code completion. A single key action on a modification key, such as the Shift key or the Alt key does not create an independent event. This provides the methods for saving, exporting and printing documents. This code shows that you do not get the type that you specify. Common pieces of reusable Python or UNO features must be stored in My macros within (User Profile)/Scripts/python/pythonpath. It displays the names in a message box. This is a transfer channel which permits direct communication with the database. These in turn contain the various cells. To simplify access to the tables, LibreOffice, however, provides some methods which operate using columns. RectangleShape.CharFontName = "Arial". LibreOffice Basic provides a whole range of methods for reading and writing files. 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 ShapeCollection is added to the page using the Group method and returns the actual Group object that can be edited like an individual Shape. It may not be available in all types of documents. Base includes additional functionality that allows you to create full data-driven applications. 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. Or this much simpler function can be used. The following example uses this method to create an object of cell C3. The applications are: Writer (a word processor), Draw (vector graphics drawing), Impress (for slide presentations), Calc (spreadsheets), Base (a database front- end), and Math (for writing formulae). A single variable can take up to four bytes of memory. Programmers who want to work directly with Java or C++ rather than LibreOffice Basic should consult the LibreOffice Developer's . Note - VBA : Compatibility between OpenOffice.org Basic and VBA relates to the OpenOffice.org Basic language as well as the runtime library. 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. When the dimensions of the data field are changed, all contents are lost. The LibreOffice Developer's Guide describes the LibreOffice API in more detail than this guide, but is primarily intended for Java and C++ programmers. It first creates the com.sun.star.frame.Desktop service and then displays the supported properties and methods in message boxes. The com.sun.star.text.TextTableRow service provides the following properties: Columns are accessed in the same way as rows, using the getByIndex, getCount, insertByIndex, and removeByIndex methods on the Column object, which is reached through getColumns. Basic languages are designed to be easy to use. This depends on the rotation of the chart. Note that this name must not begin with an underscore. XML-based files can be opened and edited with other programs. If you assign a floating point number to an integer variable, the number is rounded up or down to the next whole number. Once the method has been completed, Save saves a return value in the Ok variable. If it does not have a URL or was opened in its read-only status, it is saved under a new URL. The number of additional, deleted and modified characters for these expressions can be defined individually. A table consists of individual rows. Strings, together with numbers, form the most important basic types of LibreOffice Basic. Some drivers access file-based databases and take the data directly from them. Character objects in UNO, for example, provide the getPosition and setPosition methods through which the associated key point can be called up and changed. The LibreOffice API has been structured so that as many of its parts as possible can be used universally for different tasks. LibreOffice Basic supports Modules and Libraries. 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. Note: The example first tests whether the B parameter has been passed and, if necessary, passes the same parameter to the internal B_Local variable. The following keyboard events are available in LibreOffice Basic: Both events relate to logical key actions and not to physical actions. To make your code easier to read, you should assign meaningful names to these procedures. The page properties that are valid for both types of documents are defined in the com.sun.star.style.PageProperties service. The paragraph properties are available through the com.sun.star.style.ParagraphProperties service. (In English, at least, they must be followed by a space, tab, or return for this to work.). The associated com.sun.star.chart.ChartArea service supports line and fill properties. The, a Boolean variable which specifies whether the, com.sun.star.text.textfield.CharacterCount. 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. A variant is a universal variable that can record all conceivable values, including strings, whole numbers, floating point figures, and Boolean values. This object is then applied to the required text area in order to perform the action. The following example defines a procedure that expects an integer value A and a string B as parameters. The color gradient is depicted using a hundred graduated individual colors (StepCount). The text frame's insert position is determined by a Cursor object, which is also executed when inserted. To retrieve the next entry, the Dir function should be requested without parameters. This is useful, for example, if the contents of different databases are displayed within one document, or if a 1:n database relationship is displayed within a form. 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. The preceding function can be called within a program as follows: The code defines a variable A and assigns the result of the Test function to it. 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. You must not declare, in any module of your library, a Public variable or a Public constant, or a Sub, or a Function, named PrintDoc. This allows Java to control and manipulate LibreOffice's text, drawing, presentation, spreadsheet, and database applications, and a lot more (e.g. 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. 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. You can navigate through the control elements in any dialog by pressing the Tab key. The following example creates a rectangle and tiles the Sky bitmap that is available in LibreOffice to fill the area of the rectangle: You can adjust the transparency of any fill that you apply. A complete list of all text fields is provided in the API reference in the com.sun.star.text.textfield module. VBA: Text frames are LibreOffice's counterpart to the position frame used in Word. Large sections of the basic constructs of LibreOffice Basic are compatible with Visual Basic. Annotation fields (com.sun.star.text.textfield.Annotation) can be seen by means of a small yellow symbol in the text.
