void MyLineEdit::focusOutEvent(QFocusEvent *event){QLineEdit::focusOutEvent(event);QString curText = text();QString str = curText.replace(QStringLiteral("°"), ",").replace(QStringLiteral("′"), ",").replace(QStringLiteral("″"), "");QStringList listStr = str.split(",");if (listStr.size() != 3) return;bool isD = false, isF = false, isM = false;int d = listStr[0].toInt(&isD);int f = listStr[1].toInt(&isF);int m = listStr[2].toInt(&isM);if (!isD || !isF || !isM) return;setText(QString::number(d + f / 60.0 + m / 3600.0));}
