libreoffice basic programming guide pdf

The Basic interpreter first calculates the result of the addition process and then converts this into a string, which, as its result, produces the string 2. This chapter provides an introduction to the macro-controlled creation and editing of drawings and presentations. A space in a local file name therefore, for example, becomes a %20 in the URL. Display of the Input Box. InputBox receives three standard parameters: File:Pictures/1000020100000244000000AFAF261E64.png VBA: In VBA, the Err.Clear method of the Err object resets the error status after an error occurs. 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. 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. Comparison operators can be applied to all elementary variable types (numbers, date details, strings, and Boolean values). VBA: Through their ValueItemList property, list box forms provide a counterpart to the VBA property, ItemData, through which you can administer additional information for individual list entries. For a detailed description please refer to the LibreOffice Basic Guide which is available separately. This section describes the Integrated Development Environment for LibreOffice Basic. This section describes how to assign Basic programs to program events. LibreOffice recognizes a whole range of services that support this service. com.sun.star.awt.UnoControlCurrencyField. The LibreOffice Basic programmer can access the values through the Position property. This is an object-oriented programming interface which LibreOffice sub-divides into various objects which for their part ensure program-controlled access to the Office package. LibreOffice therefore compresses the files and saves them as a ZIP file. The com.sun.star.frame.Desktop service, which is similar to the core service of LibreOffice. Some interfaces of LibreOffice can be found in many parts of the LibreOffice API. This provides the following properties: The TextContent objects also share some methods in particular, those for creating, inserting and deleting objects. Instead, to simplify code maintenance and troubleshooting, you should create another procedure to serve as an entry point for event handling - even if it only executes a single call to the target procedure. For example, most of the page properties described in #Spreadsheets can therefore be used not only in LibreOffice Calc, but also in LibreOffice Writer. In the past, the ResultSet object provided the resident methods in the Application object for navigation within the data, for example, DataNextRecord ). It marks a certain point within a text document and can be navigated in various directions through the use of commands. LibreOffice control elements recognize different types of events that can be triggered in different situations. As can be seen in the example, the insertTextContent method expects not only the Content object to be inserted, but two other parameters: Note: The pages of a drawing document are available through the DrawPages container. A simple way is to declare it as a Private or Public variable common to the main dialog routine and the event routine. In addition to the listed properties, the com.sun.star.drawing.LineStyle service provides options for drawing dotted and dashed lines. They work in all applications of LibreOffice and help to significantly simplify formatting. LibreOffice Basic ensures that variable B is converted to a string during assignment to variable A. Furthermore, the following methods are provided through the view object of the list box: LibreOffice forms can be directly linked to a database. A string consists of a sequence of consecutive individual characters. Here are the central methods that the com.sun.star.text.TextCursor service provides for navigation: The text is divided into sentences on the basis of sentence symbols. You can open a dialog with the following code: CreateUnoDialog creates an object called Dlg that references the associated dialog. In other words, code (like the above examples) that works in a particular document type should also work for the associated template type. To get the most out of this book, you should be familiar with other programming languages. The following example demonstrates the use of ReplaceDescriptors for a search within a LibreOffice document. To make an instance of the type actual variables that can be read and stored use the Dim as New statement: As shown in the example below, the Type definition may be written at the start of a module (before the first Sub or Function). 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 possible values are: In addition to directly modifying cell content, LibreOffice Calc also provides an interface that allows you to insert, delete, copy, or merge cells. Text tables are available in LibreOffice through the TextTables list of the document object. Note: The type declaration symbol for a long integer is &. The functionality can, however, be imitated by using the IsBoolean function: The IsBoolean function defines an internal Dummy help variable of the Boolean type and tries to assign this to the transferred value. The following focus events are available: The Event objects for the focus events are structured as follows: In addition to the preceding events, which are supported by all control elements, there are also some control element-specific events that are only defined for certain control elements. which at first glance seems straightforward, ultimately proves to be something of a trap. 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). The following functions are available in LibreOffice Basic to retrieve the system time and system date: Working with files is one of the basic tasks of an application. The following example shows how the models of the control elements of a group can be iterated, exemplary displaying the states of all control elements in a given group: The code corresponds to the previous example for determining a simple control element model. The following explanations relate to working with text files (not text documents). This property provides the following options: The following example demonstrates the use of color gradients with the aid of the com.sun.star.awt.Gradient structure: This example creates a linear color gradient (Style = LINEAR). A control element of a form has three aspects: The models of the control elements of a form are available through the GetByName method of the Object form: The example determines the model of the MyListBox control element, which is located in the first form of the text document currently open. All directories needed within a hierarchy are also created, if required. The StyleFamilies are accessed by means of the document object: The example uses the StyleFamilies property of a spreadsheet document to establish a list containing all available cell styles. Python libraries help organize modules in order to prevent module name collisions. The LibreOffice API has been structured so that as many of its parts as possible can be used universally for different tasks. Jumping directly to a general program procedure from a macro can result in unclear code. The On Error instruction is the key to any error handling: The On Error Goto ErrorHandler line defines how LibreOffice Basic proceeds in the event of an error. LibreOffice Basic provides a range of tools for simplifying error handling. The InteractionHandler ensures that LibreOffice asks the user for the required login data. VBA: The rules for constructing markers are different in LibreOffice Basic than in VBA. Clicking on this symbol opens a text field, in which a comment on the current point in the text can be recorded. A dialog containing a label and a list box. In LibreOffice, the fields are administered using an object-oriented concept. 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. 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. If the bitmap is already available in LibreOffice, you just need to specify its name in the FillBitMapName property and its display style (simple, tiled, or elongated) in the FillBitmapMode property (default values in accordance with com.sun.star.drawing.BitmapMode). A single variable can take up to four bytes of memory. The most important of these events are: When you work with events, note that some events, such as the When initiating event, can be initiated each time you click the mouse on some control elements (for example, on radio buttons). Each cell is defined by its X and Y-position with respect to the top left cell which has the position (0,0). Throughout this document, the LibreOffice installation directory is represented in syntax as install-dir. If it encounters a corresponding paragraph portion, it deletes the direct formatting using the setPropertyToDefault method and assigns a MyBold character template to the corresponding paragraph portion. This code determines the object for the MyButton control element and then initializes the Ctl object variable with a reference to the element. Only at run-time can you find out which properties or methods are available for an object. Using Library.Module variable qualification grants explicit access to module-scoped variables: Constants are values which may be used but not changed by the program. dim my_doc as object Dim my_sheets as object Dim my_cell as object. This ensures that at any one time, only one option button is set. The following example steps through all the paragraphs of a text: The example first creates a ParagraphEnumeration auxiliary object. When the dimensions of the data field are changed, all contents are lost. It could be for example, A247. The expressions for searching and replacing are set using the SearchString and ReplaceString properties of the ReplaceDescriptors. The maximum length of a marker is 255 characters. This allows to determine the position and size of the elements using the Position and Size properties. The lines are dark gray (Color) and are spaced is 0.2 millimeters (Distance) apart. Spreadsheet documents, like text documents, provide a function for searching and replacing. The Option Explicit switch should be included in all Basic modules. This based on the com.sun.star.sdb.DatabaseContext service and is the root object for all database operations. The symbol bars provided by LibreOffice show the common text properties such as font type, weight and size. The drawing object can, for example, be created as follows using a spreadsheet object: A paragraph template in a text document is created in the same way: The XNameAccess and XNameContainer interfaces are used in objects that contain subordinate objects, which can be addressed using a natural language name. Note: LibreOffice provides the com.sun.star.drawing.LineShape service for line objects. At this point, only some of the abstract aspects of objects, for which the LibreOffice API provides some central interfaces, are discussed. Here are a few correct and incorrect examples of numbers in exponential format: Note, that in the first and third incorrect examples that no error message is generated even though the variables return incorrect values. The LibreOffice API provides two options for creating objects. In LibreOffice Basic, you can use object parameters to provide more information about an event to a procedure, for example: The structure and properties of the Event object depend on the type of event that triggers the procedure call. These variables are available to all the modules in their library: The value of variable A is not changed by the Test function, but is increased by one in the Flip function and decreased by one in the Flop function. When using the CompatibilityMode ( true ) function, LibreOffice Basic behaves like VBA and the Dir function, using parameter 16, returns sub-directories and standard files. A program-controlled position change of a TextCursor object has no impact whatsoever on the visible cursor. Originally, single variables were used to reduce the computing time required for the more precise double variables. Since however, the paragraph portions are edited directly, their formatting information is retained when replacing the string. The start() method of the object is used to start the example and run the screen presentation. Please, edit this topic's initial post and add " [Solved]" to The TextCursor objects available in LibreOffice Basic should not, however, be confused with the visible cursor. Sunday is considered the first day of the week. The parameters are structured in the same way as the corresponding functions in XNameContainer. VBA: LibreOffice Basic does not provide code completion. The following path references the test.odt file in the doc directory on the C: drive: file:///C:/doc/test.odt For example, support for the ChDir, ChDrive and CurDir functions is not provided. If it does, the method determines a corresponding object reference by using the getByName method and then saves the reference in a variable in Sheet. There are, however, a few key differences: Users who want to provide their forms with their own methods for event handling, should refer to the #Dialogs chapter. If you want to delete directory (including its files) use the RmDir function. ; Fishing Championships Find out about all the upcoming fishing championships and tournaments in Canada, where theyre taking place, and what First, we will declare 3 Objects to define the Calc workbook, a collection of sheets and a cell. The origin of the objects is explained at a later point in this guide. The row objects are based on the com.sun.star.table.TableRow service that has the following properties: If the OptimalHeight property of a row is set to the True, the row height changes automatically when the height of a cell in the row is changed. The endDialog method of the dialog is an improvement of endExecute. No action is performed to check if the status of the control element has actually changed. The start index of a data field usually begins with the value 0. If the width of an individual cell is changed, the width of the column that contains the cell is not changed. For all axes an additional title can be displayed. File:Pictures/10000201000000C50000006978F16295.png In LibreOffice, various types of charts can be displayed in a stacked form. If the position of the cell is fixed, it is more clear to use the following code: The above code also works with a named cell. This drawing area can be surrounded with toolbars and information areas. libreoffice 6 0 6 2 The status information remains valid until the program encounters a Resume or On Error command, whereupon the information is reset. creates both the C:\SubDir1\SubDir2 directory and the C:\SubDir1\SubDir2\SubDir3 directory. The following list describes the most important properties: Formatting information that does not refer to individual characters, but to the entire paragraph is considered to be a paragraph property. A For Each loop says "do this to everything in this set", rather than "do this n times". The definition will then be available to all routines in the module. In draft mode, the position of control elements can be changed and their properties can be edited using a properties window. Just like individual cells, you can apply formatting to cell ranges using the com.sun.star.table.CellProperties service. Here is an overview of the most important formatting properties and the points at which they are explained: The format properties are by no means restricted to the applications in which these are explained, but instead can be used universally. As with all TextContent objects, a distinction is also made with text frames between the actual creation and insertion in the document. therefore ensures that the text is preceded by a tab character (Unicode-value 9) and that a hard line break (Unicode-value 13) is added after the text. This is probably not what you want. You can also assign the elements to an individual tab page (for example page 1). WebOpenOffice Basic(formerly known as StarOffice Basic or StarBasicor OOoBasic) is a dialect of the programming languageBASICthat originated with the StarOfficeoffice suiteand spread through OpenOffice.organd derivatives such as Apache OpenOfficeand LibreOffice(where it is known as LibreOffice Basic). What is written here also applies to Impress documents. The following example inserts a paragraph after the 20th character of a text: The False parameter in the call of the insertControlCharacter method ensures that the area currently highlighted by the TextCursor remains after the insert operation. This guide provides an introduction to programming with Apache OpenOffice Basic. If you want to cleanly structure your code to prevent generating errors when you use this construct, you should not use jump commands without monitoring them. It can, for example, be moved into the next line if a line break occurs. The code used in the example then creates a list containing all charts of the first spreadsheet (Charts line = Doc.Sheets(0).Charts). XIndexAccess provides the getByIndex and getCount methods for calling the subordinate objects. Text fields are TextContent objects because they provide additional logic extending beyond pure text. The Rows and Columns objects of a sheet can access existing rows and columns as well as insert and delete them. The SetAttr function permits the properties of a file to be changed. The division between visible program elements (View) and the data or documents behind them (Model) occurs at many places in LibreOffice API. These include tables, drawings, text fields and directories. Here are the central methods of the com.sun.star.table.XtableRows interface: Whereas the getByIndex and getCount methods are available in all tables, the insertByIndex and removeByIndex methods can only be used in tables that do not contain merged cells. 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. The dispose method at the end of the code releases the resources used by the dialog once the program ends. WebLibreOffice 5.4 Writer Guide - LibreOffice Documentation Team 2018 LibreOffice is a freely-available, full-featured office suite that runs on Windows, Linux, and Mac OS X. Once the writing process has been completed, the file must be closed using a Close call: Again here, the file handle should be specified. They can be displayed as 2D or 3D graphics (com.sun.star.chart.Dim3Ddiagram service). The getCount and getByIndex methods allow the list to be further processed and belongs to the com.sun.star.table.XtableRows interface. This detail may be of interest in particular to Java- or C++ programmers, since in these languages, the interface is needed to request a method. If it does, the method determines a corresponding object reference by using the getByName method and then saves the reference in a variable in Page. A table is usually accessed in LibreOffice through the ResultSet object. The function ensures that the variable is actually assigned the correct value regardless of the country-specific settings. The options for defining color gradients and hatches let you create other colors into play. In addition to pure strings, text documents also contain formatting information. However, you usually need more than one line to get anything done, so you will typically write routinesalso known as proceduresthat consist of a This method deletes the range that is defined in the CellRangeAddress structure from the sheet. createUnoService creates an object which can be used universally. Styles are named lists containing formatting attributes. The SQL language is provided as a query language for users of SDBC. LibreOffice recognizes four main types of formatting for a fill area.
