QComboBox: remove drop Down Arrow

[GuS]

Hi folks!

Actually i want to remove the drop Down arrow since i did it in the border-image, and seems i can't:

QComboBox {
	border-image: url(:/Styles/styles/comboBox.png) 2 8 2 8 stretch stretch;
	border-width: 2x 8px 2px 8px;
	min-height: 19px;}
	QComboBox:hover {
	border-image: url(:/Styles/styles/comboBox_hover.png) 2 8 2 8 stretch stretch;
	border-width: 2px 8px 2px 8px;
	min-height: 19px;}
	QComboBox:on {
	border-image: url(:/Styles/styles/comboBox_pressed.png) 2 8 2 8 stretch stretch;
	border-width: 2px 8px 2px 8px;
	min-height: 19px;}
	QComboBox::down-arrow {
	image: none;}
	QComboBox::down-arrow:on {
	image: none;}
	QComboBox QAbstractItemView {
	border-image: url(:/Styles/styles/menuBg.png) 2 2 2 2;
	border-width: 2px 2px 2px 2px;}

QComboBox {
	border-image: url(:/Styles/styles/comboBox.png) 2 8 2 8 stretch stretch;
	border-width: 2x 8px 2px 8px;
	min-height: 19px;}
	QComboBox:hover {
	border-image: url(:/Styles/styles/comboBox_hover.png) 2 8 2 8 stretch stretch;
	border-width: 2px 8px 2px 8px;
	min-height: 19px;}
	QComboBox:on {
	border-image: url(:/Styles/styles/comboBox_pressed.png) 2 8 2 8 stretch stretch;
	border-width: 2px 8px 2px 8px;
	min-height: 19px;}
	QComboBox::down-arrow {
	image: none;}
	QComboBox::down-arrow:on {
	image: none;}
	QComboBox QAbstractItemView {
	border-image: url(:/Styles/styles/menuBg.png) 2 2 2 2;
	border-width: 2px 2px 2px 2px;}

To copy to clipboard, switch view to plain text mode 

And i have this weird result (Attached image).

Any tip?

Thanks
