如何通过用户界面中的插槽处理文件路径？

Question

I want to build a simple interface to my offline Map Project (C++), how can I replace the Path passed to My Function loadFile("G:/QT/Projects/database/city.osm.pbf"); with Open File so The Function Load File takes the path from the map file I'm choosing ?

Answer 1

void MainWindow::on_action_Open_File_triggered()
{
    QString FileName = QFileDialog::getOpenFileName(this,tr("Open File"),"C://","OSM File (*.pbf)" );
    //cout << "File Name \t"<< FileName.toStdString() <<endl;
    string FilePath2 = FileName.toStdString();
    loadFile(FilePath2);
}
