To transfer paths into Qt when selecting multiple files or folders on the desktop, you can utilize QFileDialog to handle file selection and obtain the paths in a Qt-friendly format.
Step-by-Step Explanation:
-
Include Necessary Headers:
Ensure that you have included the required headers for file dialogs and string handling:
#include <QStringList> #include <QFileDialog> -
Initialize File Dialog:
Use QFileDialog to open a dialog in save or open mode with appropriate options:
QString dir = QFileDialog::getOpenFileNames(...); -
Handle Multiple Selections:
Retrieve the list of selected files and folders as a QStringList:
QStringList open_filenames = QFileDialog::getOpenFileNames( nullptr, tr(“Select Files”), dir, tr(“All Files (*)”), QFileDialog::ReadOnly | QFileDialog::ExistingFiles ); -
Convert Paths:
Convert the QStringList to a format suitable for Qt operations:
QList<QString> qt_paths = open_filenames;
This approach efficiently integrates file selection with Qt’s type system, ensuring seamless handling of multiple file and folder paths.
