As a statement, CompatibilityMode( value ) takes a Boolean value to set or clear the mode. You will find a range of examples which use these methods in the following sections. 13 for LibO, and 1.3, ch. The IsMissing function checks whether a parameter has been passed or is left out. The majority of these properties are defined in the com.sun.star.text.BaseFrameProperties service, which is also supported by each TextFrame service. Note: Example declarations for integer variables: Long integer variables can store any whole number between 2147483648 and 2147483647. The code is first checked for obvious errors and then executed line by line. Before accessing a returned object, you should therefore check whether the returned object supports the com.sun.star.text.Paragraph service for paragraphs or the com.sun.star.text.TextTable service for tables. The Print method of the com.sun.star.view.Xprintable interface is provided for this purpose. Regardless of the type of event, all objects provide access to the relevant control element and its model. The Select command is not restricted to simple 1:1 assignments you can also specify comparison operators or lists of expressions in a Case branch. If you assign a floating point number to an integer variable, the number is rounded up or down to the next whole number. The LibreOffice API has been structured so that as many of its parts as possible can be used universally for different tasks. Whereas control elements appearing one after another in dialogs are automatically combined to form a group, grouping in forms is performed on the basis of names. LibreOffice provides the com.sun.star.text.TextCursor service for more complicated tasks, including navigating backward within a document or navigating based on sentences and words rather than TextPortions. The ForNext loop has a fixed number of passes. They are suitable for binary specifications that can only adopt one of two statuses. The Map AppFont (ma) replaces the Twips unit to achieve better platform independence. For example, to create Yes, No and Cancel buttons (value 3) where Cancel is the default (value 512), the parameter value is 3 + 512 = 515. This code inserts the test.jpg graphic and adapts its appearance using the Adjust properties. 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 following responses, which are defined in the com.sun.star.beans.PropertyState enumeration, are possible: com.sun.star.beans.PropertyState.DIRECT_VALUE, the property is defined directly in the text (direct formatting), com.sun.star.beans.PropertyState.DEFAULT_VALUE, the property is defined by a template (indirect formatting), com.sun.star.beans.PropertyState.AMBIGUOUS_VALUE. Then you can use the "perpetual" Do Loop: The WhileWend loop construct works exactly the same as the Do WhileLoop, but with the disadvantage that there is no Exit command available. 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. LibreOffice Basic predefines several constants. You can close a dialog by clicking the close button on the title bar of the dialog window. To improve clarity, you should avoid using Option Base 1. The On Error Goto 0 call at the end of the code resets the status information of the error (the error code in the Err system variables) so that an error occurring at a later date can be clearly recognized. VBA: The basic idea of search and replace in LibreOffice is comparable to that used in VBA. No action is performed to check if the status of the control element has actually changed. However, unlike the old Application object, StarDesktop is primarily responsible for opening new documents. The easiest way to change a variable from one type to another is to use an assignment. You can also have loops with an undefined number of passes. Methods can be understood as functions that relate directly to an object and through which this object is called. This can be done using the createUnoService function: This call assigns to the Obj variable a reference to the newly created object. The first section deals with the anatomy of text documents and concentrates on how a LibreOffice Basic program can be used to take iterative steps through a LibreOffice document. Possible formats are: The following functions form the counterpart to the DateSerial and TimeSerial functions: These functions extract the date or time sections from a specified Date variable. The entire LibreOffice API is based on these interfaces, which are described in more detail in the following chapters of this document. The properties of the text frame objects are set to the starting values required. You can add a shadow to most drawing objects with the com.sun.star.drawing.ShadowProperties service. The ASCII character set is a set of codes that represent numbers, characters, and special symbols by one byte. 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. The method getTextTables() of the text document object is used for this purpose: Note: 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. However, the names are not case-sensitive. To use bitmap projection as a fill, you must set the FillStyle property to BITMAP. So Replace("This is a test", " ", "_") yields "This_is_a_test" :D. Warning: In the same way, the following example checks whether MyTime is between 12 and 14 hours. The following properties can be specified: The following example shows how the number of pages can be inserted into the footer of a document. You do, however, have the option of switching to a TextCursor which allows for navigation at the level of characters, sentences and words. To do this, all option buttons of a group must contain the same name. Extensive examples are provided to help you quickly develop your own LibreOffice Basic programs. Again an auxiliary structure, in this case com.sun.star.drawing.Hatch, is used to define the appearance of hatches. Note: As of LibreOffice Version 3.3, this status does not show in the GUI, nor is there any GUI way to re-enable the feature. StarOffice 5: StarDesktop.loadComponentFromURL supersedes the Documents.Add and Documents.Open methods from the old LibreOffice API. The copyRange method functions in the same way as the moveRange method, except that copyRange inserts a copy of the cell range instead of moving it. If the cursor of LibreOffice is in a cell, then the name of that cell can be seen in the status bar. Since replacing parts of character sequences is one of the most frequently used functions, the Mid function in LibreOffice Basic has been extended so that this task is performed automatically. For Windows the recursion level is 5800. Buy a printed copy. The function ensures that the variable is actually assigned the correct value regardless of the country-specific settings. An example of the use of XNameAccess is provided by the sheets object of a spreadsheet. The following example shows how all text fields of a text document can be traversed in a loop and checked for their relevant type. This service can be addressed in LibreOffice Basic using the global name StarDesktop. This code uses the String-property of the rectangle to insert the text and the CharWeight and CharFontName properties from the com.sun.star.style.CharacterProperties service to format the text font. The following example shows how these can be used in conjunction with a TextCursor. This function creates directories and sub-directories. The following is a list of several methods for editing highlighted areas using a TextCursor and which also support the com.sun.star.text.TextCursor service: The com.sun.star.text.TextCursor service supports all the character and paragraph properties that were presented at the start of this chapter. A ResultSet is a type of marker that indicates a current set of data within a volume of results obtained using the SELECT command. 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. The hasByName, getByName and insertByName methods are obtained from the com.sun.star.container.XNameContainer interface as described in #Introduction to the API. The following example sets the page size of a drawing document which has just been opened to 20 x 20 centimeters with a page margin of 0.5 centimeters: Warning: placeholders in both VBA and LibreOffice Basic. To pass parameters as values, use the ByVal keyword. Unicode increases the length of a character to four bytes and combines different character sets to create a standard to depict as many of the world's languages as possible. The fourth parameter of the loadComponentFromURL function is a PropertyValue data field. Changes made to the variables are retained when the procedure or function is exited: In this example, the value A that is defined in the Test function is passed as a parameter to the ChangeValue function. Note: To prevent this effect, the user can access the associated paragraph portions rather than the entire paragraph. The following program code shows how the Step value in event handlers of the Next and Prev buttons can be increased or reduced and changes the status of the buttons. For a detailed description please refer to the LibreOffice Basic Guide which is available separately. The ISO 8859 character sets provide an international standard. The interfaces to various LibreOffice applications, which allow for direct access to Office documents. If you click on Yes, the new or changed styles will be copied into the document. The following is a practical example of this. When administering strings, LibreOffice Basic uses the set of Unicode characters. Therefore, before copying the content from B to A, B has to be converted into A's internal format. Libreoffice basic programming guide pdf Anyone who is already familiar with LibreOffice Basic programming can find additional information in the Developer's Guide on LibreOffice Basic and LibreOffice programming. Note: If you want to use such a name, you must tell Basic where to look. The origin of the objects is explained at a later point in this guide. If the directory contains sub-directories or files, these are also deleted. The type declaration symbol for an integer variable is %. However, as a result, the same character value can represent different characters in different languages. This example uses the insertByIndex method to insert a new column into the fourth column position in the sheet (index 3 - numbering starts at 0). A database form corresponds to a standard LibreOffice form. They may essentially consist of standard text, but can be placed at any position on a page and are not included in the text flow. VBA: In VBA, the Err.Clear method of the Err object resets the error status after an error occurs. Note: Here are a few examples: The following example shows how all empty lines in a text document can be removed with the help of the regular expression ^$: So far, this chapter has only dealt with text paragraphs and their portions. If you want to format the individual objects of a group, apply the formatting before you add them to the group. They work in all applications of LibreOffice and help to significantly simplify formatting. There are no practical limits on the indexes or on the number of elements in an array, so long as there is enough memory: Note: All of the drawing objects that are described in the previous sections can also be rotated and sheared using the com.sun.star.drawing.RotationDescriptor service. The type of removal is defined by one of the following values from the com.sun.star.sheet.CellDeleteMode enumeration: The XRangeMovement interface provides two additional methods for moving (moveRange) or copying (copyRange) cell ranges. In addition to the drawing functions that are provided by the Presentation property, the presentation document has a presentation object that provides access to the main properties and control mechanisms for presentations. push of a normal button, you can also close an open dialog window with the endExecute method: The dialog object must be accessible from the event routine. The FileExists function can be used to check whether a file exists: When working with files, it is sometimes important to be able to establish the file properties, the time the file was last changed and the length of the file. You can also use the com.sun.star.drawing.Text service to position and format text in drawing object. The color intensity of the start and end colors is 150 percent (StartIntensity and EndIntensity) which results in the colors seeming brighter than the values specified in the StartColor and EndColor properties. The figure above shows the LibreOffice Basic development environment with a dialog window that contains two list boxes. All occurrences of the name, A * indicates that the preceding character may be repeated any number of times. The program now checks whether the ResultSet actually exists and traverses the data records using a loop. For a more detailed picture, see the API reference. The queries are accessed by means of the QueryDefinitions method of the data source. Here, you will find an overview of the most common of these interfaces. Note: The methods for inserting and deleting rows use the Rows object function in the same way as the methods shown for editing columns using the Columns object. 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. The False parameter in the previous function call specifies whether the area passed over with the cursor movement is highlighted. Each of these documents may contain several spreadsheets. The inner loop processes the paragraph portions in these paragraphs. The main property for single-color fills is: To use the fill mode, you must the FillStyle property to the SOLID fill mode. They provide a very convenient way to store, maintain, and distribute styles, macros, boiler-plate text, and other useful things. The insertCell method is used to insert cells into a sheet. 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. Drawing objects include shapes (rectangles, circles, and so on), lines, and text objects.
