PySide2 set base dir in QFileDialog.getOpenFileNames()

[Please_Help_me_D]

Hi,

I'm very new to python.
I'm trying to open QFileDialog.getOpenFileNames() and set base dir. If I do it as follows:

file_names = QFileDialog.getOpenFileNames(self, self.tr("Select one or more LAS files to open"),
             "C:/Program Files", "LAS (*.las);; all (*.*)")

It works and the current directory is "C:/Program Files"

Now I want to set current directory as base.
To do so I write:

        current_dir = os.getcwdb()
        file_names = QFileDialog.getOpenFileNames(self, self.tr("Select one or more LAS files to open"),
             current_dir, "LAS (*.las);; all (*.*)")

I get the error:
FIXME Subscripted generics cannot be used with class and instance checks
Traceback (most recent call last):
File "C:/.../lasreader.py", line 19, in on_add_btn_clicked
file_names = QFileDialog.getOpenFileNames(self, self.tr("Select one or more LAS files to open"),
TypeError: 'PySide2.QtWidgets.QFileDialog.getOpenFileNames' called with wrong argument types:

@Please_Help_me_D use os.getcwd() instead of os.getcwdb()

@eyllanesc thank you!

@Please_Help_me_D said in PySide2 set base dir in QFileDialog.getOpenFileNames():

os.getcwdb()

Even better, don't use a Python function for passing a parameter to a Qt method when a suitable Qt one is available: QDir::currentPath(). At least that is returned in the internal format used by Qt for paths which is technically what is expected by QFileDialog.getOpenFileNames().

@JonB yes, thank you for the hint!
