error: ‘class QComboBox’ has no member named ‘setCurrentText’;

Question

我遇到过这样的错误，

error: ‘class QComboBox’ has no member named ‘setCurrentText’; did you mean ‘currentText’?
             x_cn_num->setCurrentText(QApplication::translate("MainWindow", "0", 0, QApplication::UnicodeUTF8));
                       ^~~~~~~~~~~~~~

然而，我检查了official documentation，"setCurrentText"正是QComboBox的兼容成员。

如果你知道真正的原因和解决方法，请给我一些线索。

您正在尝试使用 Qt 3.0 函数。您应该使用文档中链接的替代函数（在本例中为 setItemText），或者如果您真的想使用旧函数，则需要将 QT_DISABLE_DEPRECATED_BEFORE 定义为 0.
