Java – height of the list component at ireport

I have a list component in my report that displays a set of data.Its height is determined during runtime according to the size of the Set(JRBeanCollectionDataSource).I want to create a rectangle whose height is the same as the list.How can i do this? Thanks.

Best Answer

You can put List element and Rectangle in Frame container.

The sample:

<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>

You should set stretchType property for rectangle as RelativeToTallestObject and set textField's (lying in list) isStretchWithOverflow property as true.

The result will be:
