Qt-QCalendarWidget只能选中周一及获取更新日期

获得更新日期：

1 //  ui.calendarWidget->setVerticalHeaderFormat (QCalendarWidget::ISOWeekNumbers);// lyy : 2016/8/26 8:54:14 说明:显示星期数
2     ui.calendarWidget->setVerticalHeaderFormat (QCalendarWidget::NoVerticalHeader);// lyy : 2016/8/26 8:56:07 说明:不显示星期数
1   void OnCalendarSelectChanged();
2         // lyy : 2016/8/26 8:27:56 说明:天或年更改时
3         void OnCalendarYearMonthChanged (int iYear, int iMonth);
1 connect (ui.calendarWidget,        SIGNAL (selectionChanged()),        this,        SLOT (OnCalendarSelectChanged()));
2     connect (ui.calendarWidget,        SIGNAL (currentPageChanged (int , int)),        this,        SLOT (OnCalendarYearMonthChanged (int, int)));
 1 QString AlarmPaper::strDateFromat = QObject::tr ("yyyy-MM-dd");
 2 void AlarmPaper::OnCalendarSelectChanged()
 3 {
 4     //const QChar* str=GlobalConstant::strDateFromat.data();
 5     mFlagTime = QDateTime (ui.calendarWidget->selectedDate());
 6     QString strTime = mFlagTime.toString (strDateFromat);
 7     ui.timeLabel->setText (strTime);
 8 }
 9 void AlarmPaper::OnCalendarYearMonthChanged (int iYear, int iMonth)
10 {
11     // lyy : 2016/9/20 10:57:18 说明:update the time mFlage
12     mFlagTime = QDateTime (QDate (iYear, iMonth, mFlagTime.date().day()));
13     QString strTime = mFlagTime.toString (strDateFromat);
14     ui.timeLabel->setText (strTime);
15 }
