Stretch with overflow Detail band not working as e

I have a simple report. It has two bands title and detail. In the Title I have a static text, in the Detail I have one textField.

The textField is set to stretchwithoverflow = "true". If I set the height for this field to fit one raw information, I get for the larger information one and a half rows. So one textField, in the textField I have 2 rows information, first row displayed correctly, second one - I can see a half height.

Can this be done? Expand only the rows that contain larger information and the larger information will fit well in the text field?

回答1:

In the same band if there are more items and you want to have all same stretched. It has to be set to all of them to stretchType="RelativeToTallestObject" and isStretchWithOverflow="true".

    <textField isStretchWithOverflow="true" pattern="###0">
            <reportElement stretchType="RelativeToTallestObject" x="1576" y="0" width="91" height="20"/>
            <textElement textAlignment="Center"/>
            <textFieldExpression class="java.lang.Long"><![CDATA[$F{count_tohfa}]]></textFieldExpression>
        </textField>

Report property: Add this

net.sf.jasperreports.text.save.line = true

net.sf.jasperreports.export.html.wrap.break.word = true
