QFileDialog not started in needs dir

Mihaill

Hi!
I use Ubuntu 20.
QFileDialog not started in needs dir, hi started in /home

filePaths = QFileDialog.getOpenFileNames(self, "Open npy", "./dbFiles", "npy files (*.npy )")[0]

How this fix ?

"./dbFiles"

You're using relative path. Relative paths are relative to current working directory.
Try to pass an absolute path instead.

I try this, but this too not work:

filePaths = QFileDialog.getOpenFileNames(self, "Open npy", "/home/owner/PythonProjects/add3DImagesInDb/dbFiles", "npy files (*.npy )")[0]

@Mihaill
"Not work" meaning "does not start in /home/owner/PythonProjects/add3DImagesInDb/dbFiles"?
Before posting this you would have made sure that /home/owner/PythonProjects/add3DImagesInDb/dbFiles really does exist (case-sensitive) as a directory, wouldn't you....? E.g. your username is owner, is it?
Open a terminal and show the output from: ls -ld /home/owner/PythonProjects/add3DImagesInDb/dbFiles

Mihaill

Dir is exist /home/owner/PythonProjects/add3DImagesInDb/dbFiles
This command works

cd /home/owner/PythonProjects/add3DImagesInDb/dbFiles

This code open dialog in /home

filePaths = QFileDialog.getOpenFileNames(self, "Open npy", "/home/owner/PythonProjects/add3DImagesInDb/dbFiles", "npy files (*.npy )")[0]

Then I don't know why it does not work for you but does for anyone else.
Try replacing "/home/owner/PythonProjects/add3DImagesInDb/dbFiles" by "/" and then by "/tmp". Where does it show for each of these?
What version of Qt are you using?

Mihaill

I use pyqt 5.15
If do "/" and "/tmp", then open /home

Hi,

How did you install PyQt ?

Mihaill

I use pycharm for installing

SGaist

In a virtual environment ?
Can you test your application outside of PyCharm ?

JonB

@Mihaill
Also what does print(QDir("/home/owner/PythonProjects/add3DImagesInDb/dbFiles").exists()) run from your program in its PyCharm/virtual environment tell you?

Mihaill

@JonB said in QFileDialog not started in needs dir:

print(QDir("/home/owner/PythonProjects/add3DImagesInDb/dbFiles").exists())

It's return True

Linux work on laptop.
If I run app with outside , then open /home in QDialog

So you seem to be saying it starts in /home and ignores your directory parameter in all cases.

In that case I give up, works fine for me in Ubuntu 20. Though I only use C++. You have not said which Qt Python you are using, maybe try the opposite one, maybe it's a bug in whichever one you use.

Please provide a minimal script that shows this behaviour.

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QFileDialog
import requests

if __name__ == '__main__':

    app = QApplication(sys.argv)
    w = QWidget()
    filePaths = QFileDialog.getOpenFileNames(w, "Open npy", "/home/owner/PythonProjects/add3DImagesInDb/dbFiles", "npy files (*.npy )")[0]

    sys.exit(app.exec_())

SGaist

Using a path that exists on my machine, no problem, it opens correctly.

Can you share the exact version of the package you installed ?

@Mihaill
A couple of suggestions at this point.

Can you try some of the other static functions than getOpenFileNames(). There are getOpenFileName(), getSaveFileName() and getExistingDirectory(). Do any of these respect your requested starting directory or do they all use /home regardless?
You should be able to specify options. I'd like you to try DontUseNativeDialog in case that is relevant. I think it would be something like:

QFileDialog.getOpenFileName(w, "...", "/tmp", "...", options=QFileDialog.DontUseNativeDialog)

Instead of the static functions, try one of the ones which use a QFileDialog instance. Something like:

fd = QFileDialog(w)
fd.setDirectory("/tmp")
fd.exec()

Sorry to re-ignite this. But I am having the exact issue. Our program is C++ and we cross build Redhat, MacOS, and msys2/mingw. Using Qt 5.12 through 5.15 (whatever the latest packages are). I am also using the static function getOpenFileName().

MacOS and mingw work just fine. On both CentOS 8 and Alma 9, the native QFileDialog defaults to "Recents". I do specify a fully qualified path. I now have a #ifdef linux that sets options to DontUseNativeDialog. This works fine. But the compilers on the other OSs are complaining that passing in zero is deprecated. So I am out looking for a solution....and if nothing else, to say that the OP is not delusional.
