how to have a directory dialog

问题

In PyQt, how does one display a file browser that shows and selects only directories (not files)?

And how does one retrieve the name of the selected directory?

回答1:

From inside your QDialog/QWidget class, you should be able to do:

file = str(QFileDialog.getExistingDirectory(self, "Select Directory"))
