If you are interested in only the mouse click, your macro should ignore all calls where PopupTrigger is TRUE. Pie charts (com.sun.star.chart.PieDiagram) do not contain any axes and cannot be stacked. The ResultSet object provides Update methods for modifying values, which are structured in the same way as the get methods for retrieving values. There is no type declaration symbol for date variables. You should instead use Basic object ThisComponent. While this term may be familiar to Java programmers, it is not used in Basic. 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. Furthermore, it creates a data field for two PropertyValue entries named PrinterProperties. The entire LibreOffice API is based on these interfaces, which are described in more detail in the following chapters of this document. The endDialog method of the dialog is an improvement of endExecute. 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. The named _blank value for the Frame parameter ensures that LibreOffice creates a new window for every call from loadComponentFromURL. LibreOffice Basic provides two functions to convert lowercase characters in a string to uppercase and vice-versa. The replacement function of LibreOffice is particularly effective when used in conjunction with regular expressions. LibreOffice Basic predefines several constants. If you click on Yes, the new or changed styles will be copied into the document. Dialogs such as this one are described as modal because they do not permit any other program action until they are closed. Programmers who want to work directly with Java or C++ rather than LibreOffice Basic should consult the LibreOffice Developer's Guide instead of this guide. For example, you can check whether a user has typed a valid number or date. Using the DBG_ properties is a very crude method to discover the contents of an API objects. You can apply all the named properties to individual cells and to cell ranges. A complete If statement may be written on a single line, with a simpler syntax. The cell type is not determined by the content that is saved in the cell, but rather the object property which was used for its entry. You will find another description of dialogs in the Developer's Guide: Browse to and select the macro you want to assign. Furthermore, the SearchFlags parameter must be set so that the corresponding framework is created, if it does not already exist. The status information remains valid until the program encounters a Resume or On Error command, whereupon the information is reset. The previous examples are based on data fields of a specified dimension. By default, the parameters are passed by reference. All characters that follow an apostrophe are treated as comments: Markers can only contain Latin letters, numbers, and underscores (_). You can also use the following style to declare an integer type variable: The Dim instruction can record several variable declarations: If you want to assign the variables to a permanent type, you must make separate assignments for each variable: If you do not declare the type for a variable, LibreOffice Basic assigns the variable a variant type. As a result, it returns a data field containing the names. The Val function is different from the Csng, Cdbl and Cstr methods. This status arises, for example, when querying the bold type property of a paragraph, which includes both words depicted in bold and words depicted in normal font. Text fields can be inserted in a text document using the same methods as those used for other TextContent objects: The example inserts a text field with the current date at the start of the current text document. If you close a dialog by clicking the OK button, the Execute method returns a return value of 1, otherwise a value of 0 is returned. Properties are like the properties of an object; for example, Filename and Title for a Document object. 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. The option of creating sub-forms is also provided for this purpose. The two empty strings in the command line stand for the user name and password. Slide 3 will be changed into Slide 4, etc. If you want to format the individual objects of a group, apply the formatting before you add them to the group. The preceding call returns a page object that supports the com.sun.star.drawing.DrawPage service. The Goto ErrorHandler ensures that LibreOffice Basic exits the current program line and then executes the ErrorHandler: code. For example, support for the ChDir, ChDrive and CurDir functions is not provided. Conversely, the CStr methods use the currently selected country-specific settings when formatting numbers, dates and time details. Some DOS-specific file and directory functions are no longer provided in LibreOffice, or their function is only limited. This reflects the content of a table or the result of a SQL-SELECT command. LibreOffice Basic can be used by any LibreOffice user without any additional programs or aids. Note: If the user clicks the Cancel button or closes the window, the. LibreOffice positions the control elements of a form at drawing object level. 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 com.sun.star.frame.XStorable interface, which is responsible for saving documents. More extensive navigation options, such as the possibility of modifying values, are therefore not included. An integer variable can take up to two bytes of memory. In the previous example, if the UserInput variable contains a valid numerical value, then this is assigned to the ValidInput variable. 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. In LibreOffice Basic, the directory and all its files are deleted. Once the message box has been confirmed, it replaces the content of the window with the test2.odt file. In the past, the ResultSet object provided the resident methods in the Application object for navigation within the data, for example, DataNextRecord ). Even in the standard installation, LibreOffice Basic has all the components needed to create its own Basic macros, including: The components of the LibreOffice API that are discussed in this guide were selected based on their practical benefits for the LibreOffice Basic programmer. You can also use the keyword Public instead of Dim to declare a public domain variable: A public domain variable is only available so long as the associated macro is executing and then the variable is reset. A single variable can take up to four bytes of memory. Fill properties are combined in the com.sun.star.drawing.FillProperties service. You cannot modify the objects once they are in the group. 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: In the hexadecimal system (base 16 system), a 2-digit number corresponds to precisely one byte. Only at run-time can you find out which properties or methods are available for an object. 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 following example steps through all the paragraphs of a text: The example first creates a ParagraphEnumeration auxiliary object. Predefined queries can be assigned to a data source. Set focus. LibreOffice Basic libraries contain classes, routines and variables, Python modules contain classes, functions and variables. For this purpose, LibreOffice provides several help objects, such as the TextCursor object, which extend beyond those specified in the first section. The code listed in the example is very similar to the code listed in the previous example for determining a control element model. However there is one major difference: whereas the command format expects English abbreviations and decimal points or characters as thousands separators, the country-specified abbreviations must be used for the structure of a command format for the NumberFormats object. Whereas the Document.Tables.Add method takes on the task of creating and setting the table in VBA, this is created in LibreOffice Basic in accordance with the previous example using createInstance, initialized, and inserted in the document through insertTextContent. Forms are created using the Form Controls and the Form Design Toolbar directly within the document. In the following example, the loop is terminated during the fifth pass: The For EachNext loop variation in VBA is supported in LibreOffice Basic. The store method of the com.sun.star.frame.XStorable interface is available for this purpose: This call functions provided that the document has already been assigned a memory space. The removeByIndex method deletes the sixth column (index 5). For more information about the LibreOffice API and the Software Development Kit, visit https://api.libreoffice.org. Even the paragraph properties are available in various objects. com.sun.star.awt.UnoControlNumericalField, A currency field makes it possible to enter, display and edit currency values. Note: In addition to the standard properties, the following database-specific properties must also be set in the form: The com.sun.star.sdb.CommandType enumeration covers the following values: The database fields are assigned to the individual control elements through this property: Another control element is provided for work with databases, the table control element. To ensure that the footer line is visible, the FooterIsOn property is set to True. Once the Dlg dialog object has been initialized, you can use the Execute method to display the dialog. The declaration is made using the Dim instruction (see #The Language of LibreOffice Basic). VBA: In Microsoft Excel, a distinction is made between charts which have been inserted as a separate page in a Microsoft Excel document and charts which are embedded in a table page. 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. The following example shows how format properties can be edited in LibreOffice. In this example, the return value of the function is 123.
