Here are the associated properties of the com.sun.star.util.SearchDescriptor service: Once the SearchDescriptor has been prepared as requested, it can be applied to the text document. If a corresponding model is found, then a reference to this is saved in the Ctl variable and the search is terminated. The previous example may change the text as requested, but it may sometimes also destroy the formatting. In particular, if such a request is made by pressing the right mouse button on the control, the event will be fired twice: once for the popup menu request, and once for the real mouse event. As with all TextContent objects, a distinction is also made with text frames between the actual creation and insertion in the document. This procedure differs from VBA. This can be compared with highlighting a point in the text using the mouse. This defines what LibreOffice searches for in a document. 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. The real API call is: Sheet.getColumns.getByIndex(1). Markers cannot contain special characters, such as . If the cursor of LibreOffice is in a cell, then the name of that cell can be seen in the status bar. The runtime library from LibreOffice Basic provides several fundamental functions for these tasks. This guide provides an introduction to programming with LibreOffice Basic. A complete list of the paragraph properties can be found in the LibreOffice API reference. The individual styles can be accessed directly by means of an index: The loop added since the previous example displays the names of all cell styles one after another in a message box. For example, the following line declares an array with four integer variables: In the previous examples, the index for the array always begins with the standard start value of zero. For Each loops do not use an explicit counter like a ForNext loop does. You can access individual pages either through their number or their name. The central methods are: All methods return a Boolean parameter which specifies whether the navigation was successful. This conversion is much more elaborate than it appears: the integer B remains in the working memory in the form of a two-byte long number. The start index of a data field usually begins with the value 0. This function is similar to the one that is used in text documents as described in #Text Documents. The more functions a ResultSet provides, the more complex its implementation usually is and therefore the slower the functions are. 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. As with the loadComponentFromURL method, some options can also be specified in the form of a PropertyValue data field using the storeAsURL method. You should therefore be careful when using RmDir. As of LibreOffice Version 3.0, unlike variables, there is no way to make the definition accessible outside of the module. Note: XIndexContainer provides methods for inserting and removing elements. The Assign Action dialog lists all the available Events. If the center of a paragraph, for example, contains a word printed in bold, then it will be represented in LibreOffice by three paragraph portions: the portion before the bold type, then the word in bold, and finally the portion after the bold type, which is again depicted as normal. A double variable can take up to eight bytes of memory. The Chart object provides the property Diagram which forms the coordinate system with axes and grids, where the data finally is displayed: Different services are supported depending on the chart type (see #Chart Types). When you select an option, all the other options in the group are deactivated. The expression, is interpreted as 1.43 minus 2, which corresponds to the value -0.57. As an alternative, a validity range with start and end values can be specified for the data field declaration. LibreOffice Basic predefines several constants. To determine the current cursor position, the following test methods are provided and all return a Boolean value: If a ResultSet has been created with the ResultSetConcurrency = UPDATEABLE value, then its content can be edited. If, on the other hand, the Basic interpreter first converts the start values B and C into a string and applies the plus operator to the result, it produces the string 11. ThisComponent returns the last previously active document. The WaitUntil statement provides a greater degree of compatibility with VBA parameter usage. You can add a shadow to most drawing objects with the com.sun.star.drawing.ShadowProperties service. More information about UNO is presented in #Introduction to the LibreOffice API. 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). This example shows how you may define and use a struct, and how to reference the items within it, both with and without With. Text tables are available in LibreOffice through the TextTables list of the document object. LibreOffice Basic provides two functions to convert lowercase characters in a string to uppercase and vice-versa. In the strictest sense of the word, a service in UNO does not support methods, but rather interfaces, which in turn provide different methods. LibreOffice provides the com.sun.star.drawing.LineShape service for line objects. 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 code shows that you do not get the type that you specify. A data field contains several variables, which are addressed through an index. The following example steps through all the paragraphs of a text: The example first creates a ParagraphEnumeration auxiliary object. If the True parameter is passed here, then insertControlCharacter replaces the current text. XIndexAccess provides the methods for accessing individual objects. VBA: The basic idea of search and replace in LibreOffice is comparable to that used in VBA. The following properties are provided for 3D charts at the Diagram object: The following example creates a 3D area chart. When specifying a service name, it is only the module name which is of any importance because this must be also listed in the name. This ensures that at any one time, only one option button is set. Both interfaces provide you with an object, through which the properties for searching and replacing can be defined. If a decimal number is assigned to an integer variable, LibreOffice Basic rounds the figure up or down. You specify the qualifiers in the With statement. In VBA, the function also returns the names of the standard files so that further checking is needed to retrieve the directories only. As the second parameter, loadComponentFromURL expects a name for the frame object of the window that LibreOffice creates internally for its administration. In some cases the loop may only terminate when a condition is met within the loop. SearchDescriptor service and can be created by means of the createSearchDescriptor method of a document: Once the SearchDescriptor has been created, it receives the text to be searched for: In terms of its function, the SearchDescriptor is best compared with the search dialog from LibreOffice. You can also define arrays in which the dimension of the data fields dynamically changes. The Chr command is often used in Basic languages to insert control characters in a string. Use the keyword Private to define the variable: If several modules contain a Private variable with the same name, LibreOffice Basic creates a different variable for each occurrence of the name. Graphic objects support two of the general formatting properties: Additional properties that are supported by graphic objects are: The following example shows how to insert a page into a graphics object. More information about the available services, and their interfaces, methods and properties can be found in the reference for the LibreOffice API. What is written here also applies to Impress documents. This distinction is not made in LibreOffice Basic, because charts in LibreOffice Calc are always created as embedded objects of a table page. Building on this background, the following chapters will show how the API can be used to make LibreOffice do what you want it to do. The individual pages are accessed from the sheets object, by using the getByName method from XNameAccess: The getElementNames method provides an overview of the names of all elements. You must avoid having a marker of public scope with the same name as one of the modules of the library. Line objects support all the general formatting services with the exception of areas. 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. Alternatively, if only an empty document without any adaptation is needed, a private:factory URL can be specified: The call creates an empty LibreOffice writer document. The objective of developing this interface was to provide access to as many different data sources as possible. The LibreOffice documents provide the findFirst and findNext methods for this purpose: The example finds all matches in a loop and returns a TextRange object, which refers to the found text passage. The previous example shows how a text table can be created. The service term used in LibreOffice Basic therefore corresponds to the type and class terms used in other programming languages. Another mechanism for changing the text of headers and footers is available for text documents (LibreOffice Writer) because these consist of a single block of text. The assignments. Most charts in LibreOffice can also be displayed with 3D graphics. Or this much simpler function can be used. The interpreter, which is needed to run LibreOffice Basic macros. Many parts of LibreOffice Basic are identical to Microsoft Visual Basic for Applications and Microsoft Visual Basic. Finally, the following information symbols are available and can also be displayed by adding the relevant parameter values: The following call displays an information box with the Yes and No buttons (value 4), of which the second button (No) is set as the default value (value 256) and which also receives a question mark (value 32), 4+256+32=292. LibreOffice Basic provides the MsgBox and InputBox functions for basic user communication. In this example, variable A is a string, and variable B is an integer. An option button control element provides two properties: You can also use the following properties from the model of the option buttons: To combine several option buttons in a group, you must position them one after another in the activation sequence without any gaps (Model.TabIndex property, described as Order in the dialog editor). The basic object must provide the XEnumerationAccess interface, which contains only a createEnumeration method. The text in the paragraph can be retrieved and modified using the String property: The example opens the current text document and passes through it with the help of the Enumeration object. LibreOffice control elements recognize different types of events that can be triggered in different situations. The Dir function in LibreOffice Basic is responsible for searching through directories for files and sub-directories. Anyone who has already worked with these languages can quickly become accustomed to LibreOffice Basic.

Stacked charts are charts that are arranged with several individual values on top of one another to produce a total value. In addition to the methods and properties of control elements, both dialog and control element objects have a subordinate Model object. If you want to use such a name, you must tell Basic where to look. The As keyword syntax, and the fact that a comma is not used, goes back to the roots of the Basic language. To define the cell range that you want to insert, use the com.sun.star.table.CellRangeAddress structure. Basic can handle both methods like a property Name. In the past, the ResultSet object provided the resident methods in the Application object for navigation within the data, for example, DataNextRecord ). In accordance with UNO philosophy, an Obj is described as a reference to an object which supports the com.sun.star.frame.Desktop service. If an information box contains several buttons, then a return value should be queried to determine which button has been pressed. The loop is terminated as soon as the hasMoreElements method returns the False value, signaling that the end of the text has been reached. 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. Just like individual cells, you can apply formatting to cell ranges using the com.sun.star.table.CellProperties service. In addition to linking individual lines, in LibreOffice Basic you can use colons to divide one line into several sections, so that there is enough space for several expressions. 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. creates 4 integer variables which can be described with the expressions MyInteger(1), MyInteger(2), MyInteger(3), and MyInteger(4). In the second example, the sheet is accessed by its name and the getByName method. Since LibreOffice is a platform-independent application, it uses URL notation (which is independent of any operating system), as defined in the Internet Standard RFC 1738 for file names. The following values are included in this structure: The completed CellRangeAddress structure must be passed as the first parameter to the insertCells method. 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. value in the left-hand text field of the header from the "Default" template. In LibreOffice Basic, this is irrelevant. More information about working with these buttons is discussed in #Control Elements in Detail. These are presented in detail in the #Introduction to the LibreOffice API. The corresponding properties are: The following program code shows how DBG_properties and DBG_methods can be used in real-life applications. The legend has a gray background color, is placed at the bottom of the chart, and has a character size of 7 points. The following example uses the hasByName method to check if a page called MyPage exists. All occurrences of the name, A * indicates that the preceding character may be repeated any number of times. The dialog then changes its appearance as follows: The strings of a Dialog can be localized, see the Developer's Guide chapter #Dialog Localization. The following values are available: The following example creates a circular slice with a 70 degree angle (produced from difference between start angle of 20 degrees and end angle of 90 degrees). An example for the grouped option button: Text fields allow users to type numbers and text. Note: 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. The outer loop refers to the paragraphs of the text. A drawing object for a spreadsheet document, for example, can therefore only exist in conjunction with this one document. Each type of style provides a whole range of individual formatting properties. LibreOffice does not limit the number of pages in a drawing document. Whereas the dialog functions are available in all LibreOffice documents, the full scope of the form functions are only available in text and spreadsheets. The updateString method, for example, allows a string to be written. This provides the following properties: The TextContent objects also share some methods in particular, those for creating, inserting and deleting objects. The syntax of such method calls is oriented towards classic functions. The variable Rect determines the position and size of the chart within the first sheet in the spreadsheet document. All properties form part of the associated model objects. If a dialog contains an OK or a Cancel button, the dialog is automatically closed when you click one of these buttons. Once the method has been completed, Save saves a return value in the Ok variable. A text field can contain one or more lines and can be edited or blocked for user entries. 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. Documents are opened, imported and created using the method StarDesktop.loadComponentFromURL(URL, Frame, SearchFlags, FileProperties) The first parameter of loadComponentFromURL specifies the URL of the associated file. To access the view of a control element form, you need the associated model. To use bitmap projection as a fill, you must set the FillStyle property to BITMAP. Such objects and services are also known as context-independent services. LibreOffice recognizes four main types of formatting for a fill area. In other terms, you may think of a struct as a record, or part of a record. To do this, the function expects a Format expression to be specified, which is then used as the template for formatting the numbers.
