QTableView - Selection background color

Question

Hi, I am using the following code for set the style for the table in simulator(S60)(Nokia Qt SDK).

searchTable->setStyleSheet("background: rgb(255,255,255);color:rgb(0,0,0); font-family:Arial Narrow;font-size:20px; border: 4px outset rgb(255,255,255);gridline-color: #669933;"
                           "selection-background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,stop: 0 #486909, stop: 1 white);"
                              );

But When I am selecting the element in the data I got the following output. Please find the attachment.

Please help me.... What I did wrong .. Thanks in advance.
