I need the user to select either one folder or one file with a specific extension. Since the FileMode of QFileDialog is not a QFLag, i cant set FileMode (ExistingFile | Directory).
Is there any trick or workaround to solve my problem?
In short, the only solution - write your own dialog. In discussing the details are correct: "It would be hard to create a combined directory and file dialog. Much because it would be impossible to tell if you pick a directory or just want so enter it to look for other directories or files."
QFileDialog has only one button that which takes one of two states: Open (dir) | Select. But you need two buttons in the same time.
I think that you don't need to do that. Just
Looks like this should be enough because the description for this flag says
bq. The name of a directory. Both files and directories are displayed. eq.
That's right, displays directories and files. But you can select only directories :) That said, the problem of an only one button
Oh, I see. Well, the first that comes to mind is to create a widget which contains a button (or radio button group) and a file dialog. A click on a button changes the fileMode() from Directory to ExistingFile and vice versa. I'm not sure this will look great in terms of UI, but I don't see any other easy solution.
i think i a desktop application, having radiobuttons like that to choose a dialog is a bad solution. Also in my case the user neednt to know if it is a folder or a file, since it doesnt matter at all.
It was just an idea, I'm not forcing you to follow it :).
I just run into a similar problem where the user needs to choose a directory or a file from a File Dialog
Here's my hack to solve it.
subclass your class from QFileDialog and set the FileMode to AnyFile
QFileSystemModel *model = new QFileSystemModel; model->setRootPath(QDir::currentPath()); QStringList filenames; QList<QUrl> urls; urls << QUrl::fromLocalFile(QDesktopServices::storageLocation(QDesktopServices::DesktopLocation)) << QUrl::fromLocalFile(QDesktopServices::storageLocation(QDesktopServices::DocumentsLocation)); mfiledialog->setSidebarUrls(urls); mfiledialog->setFileMode(QFileDialog::AnyFile); mfiledialog->setViewMode(QFileDialog::Detail);
Then have a slot to change FileMode on currentchanged signal as follows
void MainWindow::on_mfiledialog_currentchanged(QString filedir)
QFileInfo finfo = QFileInfo(filedir);
