Hvor bliver rækkerne genereret?

Jeg har tidligere brugt % (modulo) til at skifte farve på hver anden række. Ved at gennemløbe en løkke, og tage modulo 2 af iteratoren:

loop
  if ((iterator % 2) == 0)
    // Udskriv med den ene farve
  else
    // Udskriv med den anden farve
end loop

God ide. Gør det. ;-)

Rækkerne bliver generet i "createReportDefinition ()". Den metoder som du bruger kender jeg godt:-) Du finder jo sådan set bare ud at om tallet et lige eller ulige. Men det kan ikke bruges i denne sammenhæng. Som du kan se i funktion angiver man kun hvor mange kolonner der skal være - og rækkerne blive genereret automatisk.

sondergard: Hov, sorry. Det var ikke for at være sarkastisk eller noget, jeg troede det var spørgeren der skrev. :)

Så må du bruge noget funktionalitet i JFreeReport. Den kender jeg ikke, så jeg kan ikke hjælpe dig.

Nu ved jeg overhovedet ikke hvordan det fungerer, men du bruger
  report.getItemBand().addElement(factory.createElement());
Så jeg opfatter at et element i report er en række?

Kan du så ikke bruge
  Array[] elements = report.getItemBand().getElementArray();
For at få antallet af rækker ud?

http://www.jfree.org/jfreereport/javadoc/org/jfree/report/Band.html#getElementArray() <-- man skal så åbenbart ikke ændre i elementerne...........

Hov - det var jo self Element[]...

Hmm - jeg fandt aldrig frem til et svar.

Hvis nogen føler sig snydt må i jo give lyd fra Jer.
