知道了每个 widget 后,就可以像下面这样用 QSS 修改 QCalendarWidget 的样式了。
示例1:

#qt_calendar_calendarview {
    background: white;
}

#qt_calendar_navigationbar {
    background: rgba(215, 215, 215, 255);
}

QToolButton {
    icon-size: 30px, 30px;
    width: 80px;
    height: 30px;
}

QToolButton#qt_calendar_prevmonth {
    background: green;
    width: 40px;
    qproperty-icon: url(:/img/left.png);
}

QToolButton#qt_calendar_nextmonth {
    background: blue;
    width: 40px;
    qproperty-icon: url(:/img/right.png);
}

QToolButton#qt_calendar_monthbutton {
    background: yellow;
    padding-right: 20px;
}

QToolButton#qt_calendar_yearbutton {
    background: magenta;
}

QToolButton#qt_calendar_monthbutton::menu-indicator{
    subcontrol-origin: padding;
    subcontrol-position: center right;
    right: 3px;
    width: 10px;
}

QAbstractItemView {
    color: black;
    selection-color: white;
    selection-background-color: rgb(255, 174, 0);
    font: 15px;
}
