Put a button in a GUI in order to open a folder not a file

[john_hobbyist]

Hello I am trying to put a button icon on a GUI Widget, so that when I press it to let me select a folder not a file. After google searching I found this: https://stackoverflow.com/questions/41587541/pyqt-assign-to-a-button-the-ability-to-choose-a-directory So, my try is this:

dialog = QFileDialog()
file = dialog.getExistingDirectory(None, "Select Folder")
self.tb.addWidget(dialog)

The problem is that when I execute the code, the first thing I see is a select directory menu, not the GUI on which I need to place the icon button and when I choose folder the code collapse. When I remove the above code, everything works fine.... Do you see something strange on my code?

You need to write this in the slot attached to the button's clicked() signal.

Ok, I have build a QPushButton that when pressed it calls do_something() method. What do I put inside the method so that I can choose a directory and not a file...??

Because when I tried file = dialog.getExistingDirectory(None, "Select Folder") with QPushButton I got this error:
AttributeError: 'QPushButton' object has no attribute 'getExistingDirectory'

Then your dialog variable must have been a QPushButton.... And that is not what you show with your earlier dialog = QFileDialog().

@john_hobbyist apparently, you named your QPushButton dialog.

getExistingDirectory is a static function, you can simply call it this way:

QString dir = QFileDialog::getExistingDirectory(this, tr("Open Directory"),
                                                "/home",
                                                QFileDialog::ShowDirsOnly
                                                | QFileDialog::DontResolveSymlinks);

@JonB Yes, I deleted the code I showed on first post and I wrote new code as you told me to use different rationale...What should I do now with the method do_something() ??

@J-Hilk Thanks but I do not know how to transform C/C++ to python...I use PyQt5...

@john_hobbyist
But you had something which worked for this originally: file = dialog.getExistingDirectory(None, "Select Folder"). Or you might change it to:

dirName = QFileDialog.getExistingDirectory(self, "Select Folder")

You don't need or use the dialog = QFileDialog() for calling getExistingDirectory() because it is a static method of QFileDialog.

@john_hobbyist moved this to Qt for Python subform, since it is the python part you're having problems with :D
