not rotating...what could be the reason plss help me..

 

void Transform::Apply() 

{ 

angleString = angleLE->text();

                                xcString  = xcLE->text();

                                ycString  = ycLE->text();

                                angle = angleString.toDouble();

                                xc = xcString.toDouble();

                                yc = ycString.toDouble();

 

 
geometry->setTransform(QTransform().translate(xc,
yc).rotate(angle).translate(-xc, -yc));

                               console->append("\n");

                               console->append("geometry is rotated  by
" +  angleString + " about point ( " + xcString + ", " + ycString + "
)");

                               console->append("\n");

}

but it's rotating for the first time if I click 2nd time it's not
rotating.
