Copy path to QString

问题

I need to copy the full filepath, without filename, into a QString from QFileDialog below.

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

回答1:

You use QString QFileInfo::absolutePath() const for this. See the documentation for details.

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