Question

如何把qcalendarwidget放到最前面

Answer 1

从源码可知以下按钮的名称，

//set names for the header controls.
//prevMonth->setObjectName(QLatin1String("qt_calendar_prevmonth"));
//nextMonth->setObjectName(QLatin1String("qt_calendar_nextmonth"));
//monthButton->setObjectName(QLatin1String("qt_calendar_monthbutton"));
//yearButton->setObjectName(QLatin1String("qt_calendar_yearbutton"));
//yearEdit->setObjectName(QLatin1String("qt_calendar_yearedit"));

你可以获取到QToolButton的对象，你想咋整都行。
QToolButton *tools = calendar->findChild<QToolButton*>(QLatin1String("qt_calendar_prevmonth"));
