How to set the QTreeWidget's header color and hide the dividing line?

I want to change the background color of the header when I use the QWidget. I tried the following methods but they didn't work:

QTreeWidgetItem * header = ui->treeWidget->headerItem(); 
header->setBackground(0, QBrush(QColor(185,192,201)));
header->setBackgroundColor(0, QColor(185,192,201));

setStyleSheet("QHeaderView::section { background-color:red }");

I also want to know how to hide the header's dividing line?

I've found a method to change the header's style,but I don't know why my previous method did not work.

QHeaderView::section {                          
    color: black;                               
    padding: 2px;                               
    height:20px;                                
    border: 0px solid #567dbc;                  
    border-left:0px;                            
    border-right:0px;                           
    background: #f9f9f9;                        
}

As you can read here (and as you see in your example) setBackgroundColor does not work for header item (I suspect that this is due to difference between header and row items). You should to reimplement QHeaderView or to try option described above.

Why don't you use only the stylesheet?

YourQTreeWidget QHeaderView::section {
    background-color: red; // for the bakcground
    border-right: none; // right-border of each section
    border-left: none;  // left border of each section
}
