JasperReport - avvolge il testo per mostrare il testo lungo nel campo di testo

Question

Sto usando il report jasper come strumento di segnalazione nella mia applicazione. E mi chiedo come posso avvolgere il lungo testo espandendo lo reportElement dinamicamente in direzione verticale (espandendo la dimensione della riga, non la larghezza della colonna). O c'è un modo per raggiungere questo obiettivo? Il mio approccio in basso sta troncando il lungo testo "Nome molto lungo". Potete darmi qualche suggerimento?

Answer 1

mi sono trovato la risposta:

Ho effettuato alcune ricerche aggiuntive sulle proprietà dei componenti e rectangle. E ho scoperto che ho bisogno di impostare le seguenti proprietà.

Per rettangolo:

 <rectangle> 
      <reportElement stretchType="RelativeToBandHeight" ... /> 
     </rectangle> 

Per textField:

 <textField isStretchWithOverflow="true"> 
      ... 
     </textField> 

uscita come previsto:

La sezione <detail> ...</detail> dopo la correzione:

<detail> 
     <band height="21" splitType="Stretch"> 
      <rectangle> 
       <reportElement stretchType="RelativeToBandHeight" x="0" y="0" width="88" height="21"/> 
      </rectangle> 
      <textField isStretchWithOverflow="true"> 
       <reportElement x="2" y="0" width="84" height="21"/> 
       <textElement verticalAlignment="Middle"/> 
       <textFieldExpression><![CDATA[$F{personName}]]></textFieldExpression> 
      </textField> 
      <rectangle> 
       <reportElement stretchType="RelativeToBandHeight" x="88" y="0" width="122" height="21"/> 
      </rectangle> 
      <textField isStretchWithOverflow="true"> 
       <reportElement x="90" y="0" width="118" height="21"/> 
       <textElement verticalAlignment="Middle"/> 
       <textFieldExpression><![CDATA[$F{address}]]></textFieldExpression> 
      </textField> 
     </band> 
    </detail> 

UPDATE

È inoltre possibile impostare la proprietà net.sf.jasperreports.print.keep.full.text a true per conseguire tale attraverso i vostri tutti i rapporti.

Answer 2

Inoltre è possibile rendere elegante il troncamento utilizzando le seguenti proprietà impostate sul campo di testo. Controlla questo sample

net.sf.jasperreports.text.truncate.at.char 
net.sf.jasperreports.text.truncate.suffix 
net.sf.jasperreports.print.keep.full.text
