Size of scrollbar in qlistWidget

[chikymanzanares]

I want to put a scroll bar bigger in my listWidget. I try using styleSheet, but It doesn't change the size

@
ui->listWidgetStudents->setStyleSheet("QScrollBar:horizontal {border: 2px solid green;background: cyan;height: 15px;margin: 0px 20px 0 20px;}");
@

[EDIT: code formatting, please wrap in @-tags, Volker]
