libreoffice basic programming guide pdf

You can define hundreds of dimensions in LibreOffice Basic Arrays; however, the amount of available memory limits the number of dimensions you can have. You can access individual pages either through their number or their name. Integrated Development Environment (IDE) This section describes the Integrated Development Environment for LibreOffice Basic. The XIndexContainer interface provides the insertByIndex and removeByIndex functions. It displays the names in a message box. The method provides the result in the form of a string. If you are interested in only the mouse click, your macro should ignore all calls where PopupTrigger is TRUE. The following example shows how these can be used in conjunction with a TextCursor. The Filtername property defines whether LibreOffice uses a LibreOffice Calc text filter to open files. The 0 to 127 ASCII codes correspond to the alphabet and to common symbols (such as periods, parentheses, and commas), as well as some special screen and printer control codes. A simple way is to declare it as a Private or Public variable common to the main dialog routine and the event routine. The associated com.sun.star.form.FormButtonType group of constants provides the following values: The OK and Cancel button types provided in dialogs are not supported in forms. In this case, the syntax of the function is: In the previous examples, InStr ignores uppercase and lowercase characters. LibreOffice Writer supports the following types of styles: LibreOffice Calc supports the following types of styles: LibreOffice Impress supports the following types of styles: In LibreOffice terminology, the different types of styles are called StyleFamilies in accordance with the com.sun.star.style.StyleFamily service on which they are based. If the True parameter is passed here, then insertControlCharacter replaces the current text. The options for defining color gradients and hatches let you create other colors into play. There are, however, also special drivers which access the MAPI address book, LDAP directories or LibreOffice spreadsheets as data sources. LibreOffice therefore compresses the files and saves them as a ZIP file. If the layout of the text is changed at a later date, the user only needs to change the template. The view of the control element can then be determined with the assistance of the model and using the document controller. In the same way, the following example checks whether MyTime is between 12 and 14 hours. The Map AppFont (ma) replaces the Twips unit to achieve better platform independence. LibreOffice then creates a list of the associated cell names for each of these tables. The simpler the better but syntax highlighting is necessary. The data sources from LibreOffice are not 1:1 comparable with the data sources in ODBC. The areas can be stacked (com.sun.star.chart.StackableDiagram). 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. 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. If you click on Yes, the new or changed styles will be copied into the document. LibreOffice programming with Java or C++ is a considerably more complex process than programming with LibreOffice Basic. 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. In dialogs, the distinction between data and depiction is not always as clear as in other API areas of LibreOffice. For charts in which the values of the various rows of data deviate significantly from one another, LibreOffice provides a second X and Y-axis for second scaling operations. If it does not have a URL or was opened in its read-only status, it is saved under a new URL. If the Dir function finds no more entries, it returns an empty string. It supports the createTextCursor interface for creating an associated TextCursor object. Here are a few example calls for the named functions: LibreOffice Basic provides the InStr function for searching for a partial string within another string: The StringToFind parameter specifies the string to be searched for within MyString. 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. There is, however, one main difference: a Universal Network Object may support several services at the same time. Here we rename the first sheet of the spreadsheet document. The same applies when using variant variables: Since variant variables may contain both numbers and strings, it is unclear whether variable A is assigned the number 2 or the string 11. These are: The following example shows how a query object can be created in a program-controlled manner and can be assigned to a data source. This provides the following properties: The TextContent objects also share some methods in particular, those for creating, inserting and deleting objects. The example creates an Enumeration object on the basis of this list, with which all text fields can be queried in turn in a loop. In so doing, the name of the proper com.sun.star.text.TextFrame service should be specified. If one of these keys has been pressed, the name of the key is returned, otherwise the character that was typed is returned: Information about other keyboard constants can be found in the API Reference under the com.sun.star.awt.Key group of constants. With this function, LibreOffice searches for an expression that may be similar to but not exactly the same as the search expression. Example declarations of currency variables: The handling of Basic Currency type is not reliable. check the "Macro" chapters in LibreOffice and Calc guides (1.1, ch. The following example first moves the TextCursor ten characters to the left and then three characters to the right: A TextCursor can highlight a complete area. LibreOffice Basic Macro Tutorials StarOffice (Basic) programmer's Tutorial, May 2000 LibreOffice API LibreOffice scripts make use of the LibreOffice API , documentation is available at: api.libreoffice.org OpenOffice.org 3.1 Developer's Guide Developer's Guide new home in LibreOffice wiki ScriptForge Library LibreOffice Programming 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 inserts the test.jpg graphic and adapts its appearance using the Adjust properties. If you assign a floating point number to an integer variable, the number is rounded up or down to the next whole number. In LibreOffice Basic, this is accomplished with the On Error or Resume commands. The replacement function of LibreOffice is particularly effective when used in conjunction with regular expressions. To avoid other errors resulting from implicit type conversions, LibreOffice Basic offers a range of conversion functions, which you can use to define when the data type of an operation should be converted: You can use these conversion functions to define how LibreOffice Basic should perform these type conversion operations: During the first addition in the example, LibreOffice Basic first adds the integer variables and then converts the result into a chain of characters. For a more detailed picture, see the API reference. It then converts a URL into a local file name and also displays this. This is because the contents of cell A2 were entered as a string and not as a number. You can navigate through the control elements in any dialog by pressing the Tab key. In the strictest sense of the word, a service in UNO does not support methods, but rather interfaces, which in turn provide different methods. The execute method of the dialog returns the value 0, which is the same as when you click Cancel. Several independent lists containing corner points can therefore be specified and combined to form a complete object. Annotation fields (com.sun.star.text.textfield.Annotation) can be seen by means of a small yellow symbol in the text. The associated constants are defined in the com.sun.star.sheet.GeneralFunction enumeration. Both interfaces provide you with an object, through which the properties for searching and replacing can be defined. When you port a VBA application to LibreOffice Basic, you must change any duplicate variable names. A similarity search is used so that not only the word turnover, but also the plural form "turnovers" and declinations such as "turnover's" are found. The variable RangeAddress determines the assigned cell range whose data will be displayed within the chart. LibreOffice provides the queryKey and addNew methods so that you can access existing number formats as well as create your own number formats. Functions LBound() and UBound() return respectively the lowest permitted index value and the highest permitted index value of an array. Programmers of other languages such as Java, C++, or Delphi should also find it easy to familiarize themselves with LibreOffice Basic. The minimum distance between the text edge of the drawing object is set to three millimeters. The TextCursor object in LibreOffice Basic acts independently from the visible cursor in a text document. In the present version of LibreOffice, a visible StarDesktop is no longer used. 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. Content on this page is licensed under the Public Documentation License (PDL). When the dimensions of the data field are changed, all contents are lost. The CellAddress structure provides the following values: The cell contents in the target range are always overwritten by the moveRange method. In addition to the Yes and No states, a check box can have an in-between state if the corresponding Yes or No status has more than one meaning or is unclear. LibreOffice Basic then interprets the following line as a regular instruction again. Most charts in LibreOffice can also be displayed with 3D graphics. If you want to delete directory (including its files) use the RmDir function. The right and left-hand edges of the line extend to their points of intersect with each other (LineJoint = MITER) to form a right-angle. Note: The search expression sh.rt therefore can stand for both for, The character ^ marks the start of a paragraph. (In English, at least, they must be followed by a space, tab, or return for this to work.). 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. A chart may contain its own data or may display data from the container document. The getCount and getByIndex methods allow the list to be further processed and belongs to the com.sun.star.table.XtableRows interface. VBA: Compatibility between LibreOffice Basic and VBA relates to the LibreOffice Basic language as well as the runtime library. In accordance with UNO philosophy, an Obj is described as a reference to an object which supports the com.sun.star.frame.Desktop service. All occurrences of the name, The character $ marks a paragraph end. The WaitUntil statement provides a greater degree of compatibility with VBA parameter usage. Text frame objects provide a range of properties with which the position and behavior of the frame can be influenced. Warning: The real API call is: Sheet.getColumns.getByIndex(1). 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. The most important field types and their properties are described in the following sections. Many of the styles that are described are also available for text documents. This book introduces Base, the database component of LibreOffice. They can be displayed as 2D or 3D graphics (com.sun.star.chart.Dim3Ddiagram service). This is not, for example, possible with complex SQL commands with linked columns or accumulated values. (In the following examples, A > 10 represents any condition): As in the ForNext loop, the DoLoop also provides a terminate command. Or this much simpler function can be used. 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. The return value is provided as a bit mask in which the following values are possible: The following example determines the bit mask of the test.txt file and checks whether this is read-only whether it is a directory. Through the API, for example, documents can be created, opened, modified and printed. The best way to learn Python is a simple text editor with syntax highlighting. A TextCursor object is created using the createTextCursor call: The Cursor object created in this way supports the com.sun.star.text.TextCursor service, which in turn provides a whole range of methods for navigating within text documents. In the following example the A parameter is obligatory, whereas the B parameter is optional. 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 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. After modification, the values must be transferred into the database using the updateRow()method. The area highlighted by the TextCursor therefore begins after the seventh character in the text and ends after the tenth character. . With indirect formatting, the user assigns a pre-defined template to the relevant text portion. The type declaration symbol for a single variable is !. The Sheet object that is obtained by the getByName method supports the com.sun.star.sheet.Spreadsheet service. Example declarations for integer variables: Long integer variables can store any whole number between 2147483648 and 2147483647. The API does not provide a method to change the position of a page inside a drawing document. You can access these elements through the getControl method that returns the control element by name. The variable can contain up to 15 numbers before the decimal point. Focus events indicate if a control element receives or loses focus. The formatting properties can be found in each object (Paragraph, TextCursor, and so on) and can be applied directly. The example inserts one number, one text, and one formula in the fields A1 to A3. The following methods are provided as presentation objects: The following properties are also available: LibreOffice can display data as a chart, which creates graphical representations of numerical data in the form of bars, pie charts, lines or other elements. The variable Rect determines the position and size of the chart within the first sheet in the spreadsheet document. Others use standard interfaces such as JDBC or ODBC. Anyone who is already familiar with LibreOffice Basic programming can find additional information in the Developer's Guide on LibreOffice Basic and LibreOffice programming. This method is also defined in com.sun.star.frame.XStorable and can be used to define the location of the document: In addition to the preceding methods, com.sun.star.frame.XStorable also provides some help methods which are useful when saving documents. Java LibreOffice Programming (JLOP) is intended for programmers who want to learn how to use the Java version of the LibreOffice API. LibreOffice BASIC Programming Guide. creates both the C:\SubDir1\SubDir2 directory and the C:\SubDir1\SubDir2\SubDir3 directory. One can be found in the createUnoService function mentioned at the start of this chapter. LibreOffice Basic provides a range of tools for simplifying error handling. This function creates directories and sub-directories. value in the left-hand text field of the header from the "Default" template. If you want to specify the type of a data, use a typed variable, not a constant. As a result, LibreOffice Basic enables the creation of a variable through simple usage and without an explicit declaration. This is not the case for new documents. The objective of developing this interface was to provide access to as many different data sources as possible. To provide an overview of these services, they have been combined into modules. Large sections of the basic constructs of LibreOffice Basic are compatible with Visual Basic. This defines what LibreOffice searches for in a document. If no more matches are found for the search term, the function establishes the part of the string still remaining and adds this to the return buffer. Some DOS-specific properties are no longer used in functions that expect file properties as parameters (for example, to differentiate from concealed files and system files). The StarDesktop object replaces the Application object of StarOffice 5 which previously applied as a root object. Each cell is defined by its X and Y-position with respect to the top left cell which has the position (0,0). Note: The tables inserted in a text document can be determined using a simple loop. So Replace("This is a test", " ", "_") yields "This_is_a_test" :D. Warning: The method for accessing the shape objects of a control element also uses the corresponding drawing level of the document. A variant is a universal variable that can record all conceivable values, including strings, whole numbers, floating point figures, and Boolean values. The LoadLibrary method performs this task. This section describes four services and in each instance the sample program code uses a rectangle shape element that combines several types of formatting. In all other instances (that is, if A is greater than or equal to 3), B is assigned the value 2. The function returns a number that contains the position at which the StringToFind first appears within MyString; a return value of zero indicates no match.
