c++ - 将路径复制到 QString

Question

我需要从下面的 QFileDialog 中将完整的文件路径(不带文件名)复制到 QString 中。

  QString fileName = QFileDialog::getOpenFileName(this,
      tr("Select app to install"), '/' , tr("APK Files (*.apk)"));

Answer 1

你为此使用QString QFileInfo::absolutePath() const。查看documentation for details .

QFileInfo fileInfo(QFileDialog::getOpenFileName(this,
  tr("Select app to install"), '/' , tr("APK Files (*.apk)")));
qDebug() << fileInfo.absolutePath();
