how to have a directory dialog
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?
From inside your QDialog/QWidget class, you should be able to do:
file = str(QFileDialog.getExistingDirectory(self, "Select Directory"))
Just as simple as that:
folderpath = QtWidgets.QFileDialog.getExistingDirectory(self, 'Select Folder')
Here, self represents the parent window usually the QMainWindow object.
Similarly for File dialog:
filepath = QtWidgets.QFileDialog.getOpenFileName(self, 'Hey! Select a File')
