回答1:

Got the solution. Modified all the static text fields and all the elements properties to positionType="Float".



回答2:

  1. click on the particular textfield in ireport.
  2. on the right side, see TextField properties.
  3. Check the option "STRETCH WITH OVERFLOW. it worked in my case.


回答3:

Just add the isStretchWithOverflow="true" to the textField that you want as an element.

<textField isStretchWithOverflow="true">
    <reportElement x="279" y="7" width="202" height="13"/>
    <textElement/>
    <textFieldExpression class="java.lang.String"><![CDATA[$F{name}]]></textFieldExpression>
</textField>


回答4:

The field can auto stretch with overflow, but it goes down (kinda word wrap) instead of increasing width. In PDF documents that option you look out for, would be of little or no use.

Check this other thread for further info Dynamic column cell width

EDIT Also check and include jasperreports fonts extension. Maybe it could help on a flawless deploy without OS fonts' issues.
