The method getByName() is mandatory, and should always be available. 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. All objects that support the com.sun.star.text.Paragraph service also provide support for the paragraph properties in com.sun.star.style.ParagraphProperties. Regardless of the type of event, all objects provide access to the relevant control element and its model. The following return values are available in this instance: In the previous example, checking the return values could be as follows: In addition to the information text and the parameter for arranging the information box, MsgBox also permits a third parameter, which defines the text for the box title: If no box title is specified, the default is soffice. as the decimal point. The variable Rect determines the position and size of the chart within the first sheet in the spreadsheet document. To check if the contents of a cell contains a number or a string, use the Type property: The Cell.Type property returns a value for the com.sun.star.table.CellContentType enumeration which identifies the contents type of a cell. These are: The code for saving a document can be extended by these options so that the document is only saved if the object has actually been modified and the file name is only queried if it is actually needed: The example first checks whether the relevant document has been modified since it was last saved. The hasByName, getByName and insertByName methods are obtained from the com.sun.star.container.XNameContainer interface as described in #Introduction to the API. Basic languages are designed to be easy to use. The & operator is safer when dealing with strings because it assumes that all arguments should be strings, and converts the arguments to strings if they are not strings. The following sections describe the main formatting options for spreadsheet pages. Warning: In addition to single dimensional data fields, LibreOffice Basic also supports work with multi-dimensional data fields. 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. The first 128 characters of the ISO character set correspond to the ASCII character set. Dialogs appear in the form of one single dialog window, which is displayed over the document and does not permit any actions other than dialog processing until the dialog is ended. FileNo is the handle created by the FreeFile function. To do this, a free file handle is needed, which clearly identifies the file for subsequent file access. The first example of this page may be written as: The second example of this page may be written as: The SelectCase instruction is an alternative to the cascaded If statement and is used when you need to check a value against various conditions: In this example, the name of a weekday corresponds to a number, so that the DayOfWeek variable is assigned the value of 1 for Sunday, 2 for Monday value, and so on. 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. 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 text frame is therefore inserted directly in the text flow and behaves like a character. A variation of the If statement is the If/Else clause: In this example, the variable B is assigned the value of 2 when A is greater than 3, otherwise B is assigned the value of 0. If assignment is successful, the function returns True. This is called indirect formatting. There are various ways of formatting text. Calculations that use integer variables are very fast and are particularly useful for loop counters. Note: 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. Since LibreOffice Basic is a procedural programming language, several linguistic constructs have had to be added to it which enable the use of UNO. Note: To open a PDF document in LibreOffice Draw, simply launch the application and in the menu bar, go to File > Open and then select the PDF document that you want to edit. Furthermore, the SearchFlags parameter must be set so that the corresponding framework is created, if it does not already exist. A single key action on a modification key, such as the Shift key or the Alt key does not create an independent event. 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. These objects cover not only the options, but also the current search text and, if necessary, the associated text replacement. 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 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. . Python libraries help organize modules in order to prevent module name collisions. More information about working with styles can be found in the '''#Default values for character and paragraph properties''' section in #Text Documents. The start() method of the object is used to start the example and run the screen presentation. The command: specifies the same delay, 2 seconds, as the previous example. The Internet Standard RFC 1738, upon which this is based, permits use of the 0-9, a-z, and A-Z characters. If the width of an individual cell is changed, the width of the column that contains the cell is not changed. Public domain variables are defined in the header section of a module by the keyword Dim. The functions resident in the old Application object for controlling the on-screen depiction of LibreOffice (for example, FullScreen, FunctionBarVisible, Height, Width, Top, Visible) are no longer used. en Context-dependent objects are usually created by means of an object method, on which the object depends. The return value can be overwritten several times within the function. The syntax of such method calls is oriented towards classic functions. Here, you will find an overview of the most common of these interfaces. In addition to these "real" properties, there are also properties in LibreOffice Basic which consist of two methods at the UNO level. Accessing databases is often a matter of critical speed. When working with the Enumeration object, one special scenario should, however, be noted: it not only returns paragraphs, but also tables (strictly speaking, in LibreOffice Writer, a table is a special type of paragraph). For example charts in spreadsheets can display data obtained from the cell ranges and charts in text documents can display data obtained from writer tables. You do that by using the name of the object as a qualifier. This provides the following properties: The TextContent objects also share some methods in particular, those for creating, inserting and deleting objects. The last of the drawing elements presented here are graphic objects that are based on the com.sun.star.drawing.GraphicObjectShape service. However, this call does not affect the UNO sequences that are defined through the LibreOffice API whose index always begins with 0. Here is an list of the most important properties of the table object: A table consists of a list containing rows. The WaitUntil statement provides a greater degree of compatibility with VBA parameter usage. Similarly, if you set this value to zero for a control element, the element is displayed on all the tab pages in a dialog. The shape object of the control element must already be known if the code is to function. storeAsURL provides the following options: The following example shows how the Overwrite option can be used in conjunction with storeAsURL: The example then saves Doc under the specified file name if a file already exists under the name. 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. A chart may contain its own data or may display data from the container document. The queries are accessed by means of the QueryDefinitions method of the data source. This code shows that you do not get the type that you specify. The following example creates two objects that reference the first row and the first column of a sheet and stores the references in the FirstCol and FirstRow object variables. The example below shows how the characters 0 and . LibreOffice provides various ways of establishing database connections. The lines can be stacked (com.sun.star.chart.StackableDiagram). This code inserts the test.jpg graphic and adapts its appearance using the Adjust properties.

The found expressions differ by up to two letters from the search expression: Note: The com.sun.star.table.CellProperties service provides the following properties for defining background colors and shadows: The com.sun.star.table.ShadowFormat structure and the detailed specifications for cell shadows have the following structure: The following example writes the number 1000 to the cell B2, changes the background color to red using the CellBackColor property, and then creates a light gray shadow for the cell that is moved 1 mm to the left and down. The LoadLibrary method performs this task. 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. A space in a local file name therefore, for example, becomes a %20 in the URL. Once the database connection has been established, the code used in the example first uses the Connection.createObject call to create a Statement object. Each time the function is called, the values generated previously are not available. Set focus. Parameters are normally passed by Reference in LibreOffice Basic. The following examples show you how to access a sheet either through its number or its name. The following example creates a red rectangle with a transparency of 50 percent. Before the corresponding call can be made, the polygon must be inserted into the document. its spell checker, forms designer, and charting tools). For example, support for the ChDir, ChDrive and CurDir functions is not provided. The shadow is rendered in dark gray with 50 percent transparency.
