QRGroupBand problem

Hi,

I acctualy need report with this structure:

***************************
* Group Header - full page width  *
***************************
* Column            * Column           *
*                         *                       *
***************************

But group header goes like this:

***************************
* Group Header * Column          *
**************                       *
* Column            *                      *
*                         *                      *
***************************

So I added extra Column header band and print it only to make 2nd column
start lower on page:

***************************
* Group Header *  Col header    *
**************************
* Column            *Column          *
*                         *                      *
***************************

But the Col header allways fill its interior with its color and this clears
what my group header printed (if its wider than one column).

I tried to create DummyBand as descendant of QRBand to override Print method
to stop that filling, but band is filled by some other method.
Does anybody know how to make QRBand transparent? What method should I
override to prevent drawing of frame and filling it with Color?

Can any body tell how to make my report look like I want?

Thank you very much

Martin
