Create a temporary file and fill it with data, organized according to the KugarData Document Type Definition. Then call the kugar shell command ( kugar -d Kugar data file -r Kugar template file ) to preview and print the report. See Using &kugar; shell for previewing reports for a detailed description. Use &kugar; directly in the application's code. See Using &kugar; classes for reporting for a detailed description. Create a &Qt; designer plugin, use it to build the application &GUI; in the designer and link it to the program dynamically. See Creating a &Qt; designer plugin for a detailed description. The last two ways are acceptable for &Qt; and &tde; developers; but &kugar; is designed to be a report generator, independent from a programming language and/or IDE. It uses &XML; format for describing report templates and data files. So any program can produce output in &kugar; data file format as described in KugarData DTD or even a report template file format (see KugarTemplate DTD). &kugar; shell (report viewer) can be used to preview and print the generated report. Create a report template file with &kudesigner; Create a data file with column values for detail bands of the report. Use KugarData DTD to produce correct data files. Run &kugar; shell to preview and print a report. For example, to do this, in C or C++ languages call: system("kugar -r template_file.ktf-d data_file.kdf"). Don't forget to include stdlib.h. The &kugar; library includes two widgets for use. The KReportViewer class is designed for &tde; developers. It supports a &tde; printing system and &UNIX; localization via i18n() calls. The MReportViewer class is designed for &Qt; developers and provides real crossplatforming. It can be used not only on &UNIX; platforms, but also on &Windows; and &MacOS;. In order to build a program that uses the &kugar; library, it should be linked with libkugar.so shared library, which is provided with the &kugar; distribution on all &UNIX; platforms. Include files are kugarqt.h and kugar.h for &Qt; and &tde; programs respectively. For a detailed example of how &kugar; classes can be used, look in the /shell folder in the &kugar; sources. MReportViewer (and KReportViewer too) contains several public methods that can be used. void renderReport Renders the report onto a screen. void printReport Calls the print dialog to print the report. void clearReport Clears the report on a screen and frees report data. Call this before opening the new report. bool setReportData const QString &data_file_name Sets report data from data_file_name file. bool setReportData const QIODevice &data_io_device Sets report data from data_io_device file. IO device can be any successor of the QIODevice class. For example, to fetch records directly from the database, create a QIODevice successor and redefine all necessary functionality. bool setReportTemplate const QString &template_file_name Sets report template from template_file_name file. bool setReportTemplate const QIODevice &template_io_device Sets report template from template_io_device file. IO device can be any successor of the QIODevice class. For example, to obtain a report template from network storage or database, create a QIODevice successor and redefine all necessary functionality. This is the example code of how a designer plugin is created. The code below creates a plugin for a &tde; KReportViewer widget. If a &Qt; widget is desired, replace KReportViewer with MReportViewer and kugar.h with kugarqt.h in the plugin code. The designer plugin will allow the usage of &Qt; Designer to place a KReportViewer widget onto a window and preview it correctly. Programs that make use of this plugin must be linked dynamically with it. The corresponding library is called libkugar_plugin.so. Widgets or dialogs that include KReportViewer widget must include <kugar.h> in implementation and have a forward declaration of class KReportViewer. Includes can be done with &Qt; Designer's Object Explorer (Source tab). To build the plugin run: qmake kugar_plugin.pro make kugar_plugin.h kugar_plugin.cpp kugar_plugin.pro A header file for the KugarWidgetPlugin, QWidgetPlugin successor; A source file for the KugarWidgetPlugin, QWidgetPlugin successor; A project file for the QMake utility. #include <qwidgetplugin.h> class KugarWidgetPlugin:public QWidgetPlugin { public: KugarWidgetPlugin (); QStringList keys () const; QWidget *create (const QString & classname, QWidget * parent = 0, const char *name = 0);
