下載Stimulsoft Reports Java最新版本

此示例項目顯示了在運行時創建報表并在查看器中顯示報表的可能性。您只需要顯示報表的本機Java查看器，以及使用組件創建報表的幾行代碼。

首先，我們需要創建Java查看器。創建JFrame，設置必要的選項并添加查看器控件。

public class CreateReport extends JPanel {
 
    private static final long serialVersionUID = 330448692680237867L;
    private static final Dimension FRAME_SIZE = new Dimension(800, 800);
 
    public static void main(final String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                try {
                    JFrame frame = new JFrame();
                    frame.add(new CreateReport(frame));
                    frame.setSize(FRAME_SIZE);
                    frame.setLocationRelativeTo(null);
                    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                    frame.setVisible(true);
                } catch (Throwable e) {
                    StiExceptionProvider.show(e, null);
                }
            }
        });
    }
    public CreateReport(final JFrame parentFrame) throws FileNotFoundException {
    setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
    setPreferredSize(FRAME_SIZE);
    StiViewerFx viewerPanel = new StiViewerFx(parentFrame);
    add(viewerPanel);
...

接下來，創建新的報表對象，然后使用Demo XML和XSD文件的路徑創建XML數據集對象，并將其添加到報表中。

...
    StiReport report = new StiReport();
 
    StiPage page = new StiPage(report);
    report.getPages().add(page);
    page.setName(StiNameCreation.createName(report, StiNameCreation.generateName(page)));
    String xsdPath = "/samples/Demo.xsd";
    StiXmlDatabase xmlDatabase = new StiXmlDatabase("Demo",
        StiResourceUtil.getStream(xsdPath), StiResourceUtil.getStream("/samples/Demo.xml"));
    report.setDictionary(new StiDictionary(report));
    report.getDictionary().getDatabases().add(xmlDatabase);
...

接下來，從Demo數據庫中提取信息，并使用Categories名稱創建TableSource 。

...
    StiXmlTableFieldsRequest tables = StiDataColumnsUtil.parceXSDSchema(StiResourceUtil.getStream(xsdPath));
    StiDataTableSource tableSource = null;
    for (StiXmlTable table : tables.getTables()) {
        if (table.getName().equals("Categories")) {
            tableSource = new StiDataTableSource("Demo." + table.getName(), table.getName(), table.getName());
            tableSource.setColumns(new StiDataColumnsCollection());
            for (StiSqlField field : table.getColumns()) {
                StiDataColumn column = new StiDataColumn(field.getName(), field.getName(), field.getSystemType());
                tableSource.getColumns().add(column);
            }
            tableSource.setDictionary(report.getDictionary());
            report.getDictionary().getDataSources().add(tableSource);
        }
    }
...

現在我們需要創建報表組件。首先，使用Text組件將Header band添加到報告頁面。這些組件將顯示報表標題。

...
    // Create TitleBand
    StiHeaderBand titleBand = new StiHeaderBand();
    titleBand.setHeight(0.85);
    titleBand.setName("TitleBand");
    page.getComponents().add(titleBand);
 
    // Create Title text on header
    StiText headerText = new StiText(new StiRectangle(0, 0, page.getWidth(), 0.85));
    headerText.setTextInternal("Tacticdescription");
    headerText.setHorAlignment(StiTextHorAlignment.Left);
    headerText.setName("TitleHeader");
    headerText.setFont(new StiFont("Arial", 12F, StiFontStyle.Bold));
    titleBand.getComponents().add(headerText);
 
    // Create HeaderBand
    StiHeaderBand headerBand = new StiHeaderBand();
    headerBand.setHeight(0.5);
    headerBand.setName("HeaderBand");
    page.getComponents().add(headerBand);
...

接下來，使用“Text”字段和“Image”字段添加“Data”區域。這些組件將顯示報表數據。

...
    double pos = 0;
    double columnWidth = page.getWidth() / tableSource.getColumns().size();
    Integer nameIndex = 1;
    for (StiDataColumn dataColumn : tableSource.getColumns()) {
        // Create text on header
        StiText hText = new StiText(new StiRectangle(pos, 0, columnWidth, 0.5));
 
        hText.setTextInternal(dataColumn.getName());
        hText.setHorAlignment(StiTextHorAlignment.Center);
        hText.setName("HeaderText" + nameIndex.toString());
        hText.setBrush(new StiSolidBrush(StiColorEnum.Orange.color()));
        hText.getBorder().setSide(StiBorderSides.All);
        headerBand.getComponents().add(hText);
 
        if (dataColumn.getName().equals("Picture")) {
            StiImage dataImage = new StiImage(new StiRectangle(pos, 0, columnWidth, 0.5));
            dataImage.setDataColumn("Categories." + dataColumn.getName());
            dataImage.setName("DataImage" + nameIndex.toString());
            dataImage.getBorder().setSide(StiBorderSides.All);
            dataBand.getComponents().add(dataImage);
        } else {
            StiText dataText = new StiText(new StiRectangle(pos, 0, columnWidth, 0.5));
            dataText.setText("{Categories." + dataColumn.getName() + "}");
            dataText.setName("DataText" + nameIndex.toString());
            dataText.getBorder().setSide(StiBorderSides.All);
            dataBand.getComponents().add(dataText);
        }
        pos = pos + columnWidth;
        nameIndex++;
    }
...

最后，渲染報表并在查看器中顯示它。

...
    report.Render();
 
    viewerPanel.getStiViewModel().getEventDispatcher().dispatchStiEvent(
        new StiViewCommonEvent(StiViewCommonEvent.DOCUMENT_FILE_LOADED, new StiDocument(report), null));
}
