In my application i need to use dark grey color border for my progress. by googling i changed the border color and background color successfully like,
QString st = QString ("QProgressBar::chunk {""background-color: #00B82E;""}");
st.append("QProgressBar {""border: 6px solid grey;" "border-radius: 9px;""text-align: center;""background: #00B82E;""}");
Progress->setStyleSheet(st);
but not able to find out the list of border color like "border: 6px solid grey;".How to find out list of colors like "6px solid grey" because i need to change another color for border
