Programmers who want to work directly with Java or C++ rather than LibreOffice Basic should consult the LibreOffice Developer's Guide instead of this guide. A table consists of individual rows. The runtime library: Provides standard functions which have no direct reference to LibreOffice, for example, functions for editing numbers, strings, date values, and files. The origin of the line is specified in the Location property, whereas the coordinates listed in the Size property specify the end point of the line. The structure of the associated event objects is defined in the com.sun.star.awt.MouseEvent structure which provides the following information: The constants defined in com.sun.star.awt.MouseButton for the mouse buttons are: The following example outputs the mouse position as well as the mouse button that was pressed: Note: For a more detailed picture, see the API reference that comes along in the chapter...

StarOffice 5: The database is actually accessed in LibreOffice through a ResultSet object. The LibreOffice Basic programming language can be divided into four components: Note:
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.
To create a hatch fill, the FillStyle property must be set to HATCH. What is written here also applies to Impress documents. The mechanisms explained there are identical to those for forms. The following example uses a recursive function to calculate the factorial of the numbers 42, -42, and 3.14: The example returns the factorial of the number 42 by recursively calling the CalculateFactorial function until it reaches the base condition of 0!
In the hexadecimal system (base 16 system), a 2-digit number corresponds to precisely one byte. Let us first take the properties of the table itself. This ensures that at any one time, only one option button is set. Note: Information about a pressed key is provided by the event object that LibreOffice Basic supplies to the procedure for event handling. This returns an auxiliary object, which in turn provides the XEnumeration interface with the hasMoreElements and nextElement methods. The actual replacement process is finally implemented using the replaceAll method of the document object, which replaces all occurrences of the search expression. This distinction is not made in LibreOffice Basic, because charts in LibreOffice Calc are always created as embedded objects of a table page.
For example, in the following variable declaration, MyVar1 becomes a variant and MyVar2 becomes an integer: The following sections list the variable types that are available in LibreOffice Basic and describe how they can be used and declared. For a more detailed picture, see the API reference.
The example is shown as in-line code, for clarity; in practice, the search would be inside a function, called with the name as a string parameter, and include error processing. There are four versions of the DoLoop. All the properties of the SearchDescriptor described in the previous paragraph are also supported by ReplaceDescriptor. The properties are set by means of a simple assignment: A property, just like a normal variable, has a type that defines which values it can record. Warning: This allows to determine the position and size of the elements using the Position and Size properties. That covers almost everything Microsoft Office includes. It displays the names in a message box. The ISO standard introduces new character sets (code pages) so that more languages can be correctly displayed. You can also link another action to the button to close a dialog using the PushButtonType property. If this is true, the function ends the search. To make the definition available to other modules, add the Public keyword. The start index of a data field usually begins with the value 0.
Many parts of LibreOffice Basic are identical to Microsoft Visual Basic for Applications and Microsoft Visual Basic. Keep in mind that ShowVarB only shows the expected value of C (20) because Sub Test is keeping it in scope. In addition to single dimensional data fields, LibreOffice Basic also supports work with multi-dimensional data fields. 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.
Since these function areas are available in all types of documents, they are explained first in this chapter. It only continues with the saving process if this is the case. 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. If you start the macro from the IDE, ThisComponent will still find and return your document. The following example outlines the replacement process within a drawing: This code uses the first page of the document to create a ReplaceDescriptor and then applies this descriptor in a loop to all the pages in the drawing document. Elements of the API are available through both the View and the Model. The complete name of a service consists of the com.sun.star expression, which specifies that it is a LibreOffice service, followed by the module name, such as frame, and finally the actual service name, such as Desktop. return the number of pages, words, or characters of a text. The topmost link in this forum's Macros and API Forum provides a good starting point. An example for the grouped option button: Text fields allow users to type numbers and text. If you are hoping to learn more about the program, this course will offer many lessons in learning related skills. The view of the control element can then be determined with the assistance of the model and using the document controller. 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. The return value of a function can be any type. The recursion levels are set at different levels based on the software platform.
An instance of the new type is a variable, and follows the usual rules for variable scope (see #Scope and Life Span of Variables).
When it is used with 4 arguments, to replace a sub-string in a string, Mid is an instruction, not a function: it does not return any value! The call is made by entering the procedure name at the relevant point of the program. With the help of this controller object and the model of the control element, it then uses the GetControl method to determine the view (CtlView variable) of the control element form.
In accordance with UNO philosophy, an Obj is described as a reference to an object which supports the com.sun.star.frame.Desktop service. The color gradient is depicted using a hundred graduated individual colors (StepCount). You can, for example, highlight a certain word within a text using bold type or center a line. The method getByName() is mandatory, and should always be available. Unlike LibreOffice Basic identifiers, the names of control elements are case sensitive. The following properties are provided for 3D charts at the Diagram object: The following example creates a 3D area chart. 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. Note: The functions for writing the HTML file, as well as a test code that checks the font weight of the corresponding text portions and provides paragraph portions in bold type with a corresponding HTML tag, have been added. In the latter examples, the code will be executed at least once. 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. If you are running from within the Basic IDE, debugging or exploring, then StarDesktop returns the Basic IDE itself. The values for selecting the buttons are: To set a button as the default button, add one of the following values to the parameter value from the list of button selections. The following example replaces three characters with the string is from the sixth position of the MyString string. WebThis chapter describes LibreOffice API concepts without resorting to code (that comes along in the next chapter). StarOffice 5: The Value, String, and Formula properties supersede the old PutCell method of StarOffice 5 for setting the values of a table cell. The core of a text document consists of a sequence of paragraphs. No action is performed to check if the status of the control element has actually changed. LibreOffice Basic is a fully-developed procedural programming language and no longer requires rudimentary control structures, such as GoTo and GoSub. Note: This code inserts the test.jpg graphic and adapts its appearance using the Adjust properties. The properties of the text frame objects are set to the starting values required. 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). Go to the option from the menu: Tools ==> Macros ==> Organize Macros ==> LibreOffice Basic. Finally, when calling up a text file, the eof instruction is used to check whether the end of the file has been reached: The following example shows how a text file can be read: The individual lines are retrieved in a Do While loop, saved in the Msg variable, and displayed at the end in a message box. A text field can contain one or more lines and can be edited or blocked for user entries.
All other characters are inserted as escape coding in the URLs. RectangleShape.CharFontName = "Arial". They can, however, only be used in tables that do not contain merged table cells. The computeFunction expects a constant as the parameter that describes the mathematical function that you want to use. Page 2. They provide a very convenient way to store, maintain, and distribute styles, macros, boiler-plate text, and other useful things. Text frames are considered to be TextContent objects, just like tables and graphs. When using the ResultSet's UPDATEABLE and SCROLL_SENSITIVE properties, the scope of function of a ResultSet is comparable with a Dynaset type Recordset from ADO and DAO. The getCount and getByIndex methods allow the list to be further processed and belongs to the com.sun.star.table.XtableRows interface. The ForNext loop has a fixed number of passes. The LibreOffice Developer's Guide describes the LibreOffice API in more detail than this guide, but is primarily intended for Java and C++ programmers. LibreOffice provides various functions that allow you to change the justification of a text in a table cell. One of these is used to query the value of the property and the other is issued to set it (get and set methods). If you close a dialog by clicking the OK button, the Execute method returns a return value of 1, otherwise a value of 0 is returned. Fill and line properties (com.sun.star.drawing.FillProperties and com.sun.star.drawing.LineProperties services) as well as the character properties (com.sun.star.style.CharacterProperties service) are provided for further formatting of the elements. To compare the differences between different SQL dialects, the SDBC components from LibreOffice have their own SQL parser. The values valid there can be found in the relevant VBA documentation. You can also declare type-specific variables in an array. The individual data sources are based on the com.sun.star.sdb.DataSource service and can be determined from the database context using the getByName method: The example creates a DataSource object for a data source called Customers. For this purpose, LibreOffice provides several help objects, such as the TextCursor object, which extend beyond those specified in the first section. The control codes are defined in the com.sun.star.text.ControlCharacter group of constants. However, unlike the old Application object, StarDesktop is primarily responsible for opening new documents.
The objective of developing this interface was to provide access to as many different data sources as possible. Note: Note that this name must not begin with an underscore. Cells cannot be formatted by column in LibreOffice Basic. Forms, on the other hand, are displayed directly in the document, just like drawing elements. The command: specifies a delay of 2 seconds (2000 milliseconds). Every UNO object knows what properties, methods and interfaces it already contains.
Note: This code inserts the test.jpg graphic and adapts its appearance using the Adjust properties. The properties of the text frame objects are set to the starting values required. 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).
