java - ireport 中列表组件的高度

标签 java jasper-reports ireport

我的报表中有一个列表组件,它显示一组数据。它的高度是在运行时根据 Set(JRBeanCollectionDataSource) 的大小确定的。我想创建一个高度与列表相同的矩形。我怎样才能做到这一点?谢谢。

最佳答案

您可以将List元素和Rectangle放入Frame容器中。

示例:

<detail>
    <band height="20" splitType="Stretch">
        <textField>
            <reportElement x="0" y="0" width="100" height="20"/>
            <textElement/>
            <textFieldExpression><![CDATA[$F{ADDRESS_FIRSTNAME}]]></textFieldExpression>
        </textField>
        <textField>
            <reportElement x="100" y="0" width="100" height="20"/>
            <textElement/>
            <textFieldExpression><![CDATA[$F{ADDRESS_CITY}]]></textFieldExpression>
        </textField>
        <frame>
            <reportElement x="200" y="0" width="324" height="20"/>
            <componentElement>
                <reportElement x="0" y="0" width="155" height="20"/>
                <jr:list xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" printOrder="Vertical">
                    <datasetRun subDataset="dataset1">
                        <datasetParameter name="addressId">
                            <datasetParameterExpression><![CDATA[$F{ADDRESS_ID}]]></datasetParameterExpression>
                        </datasetParameter>
                        <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
                    </datasetRun>
                    <jr:listContents height="20" width="155">
                        <textField isStretchWithOverflow="true">
                            <reportElement x="0" y="0" width="62" height="20"/>
                            <textElement/>
                            <textFieldExpression><![CDATA["Total docs: " + $F{DOCUMENT_TOTAL}]]></textFieldExpression>
                        </textField>
                    </jr:listContents>
                </jr:list>
            </componentElement>
            <rectangle>
                <reportElement stretchType="RelativeToTallestObject" x="155" y="0" width="100" height="20"/>
            </rectangle>
        </frame>
    </band>
</detail>

您应该将矩形stretchType属性设置为RelativeToTallestObject 并将 textField 的(位于列表中) isStretchWithOverflow 属性设置为 true

结果将是:
