QFileDialog- Using getOpenFile

@jsulm I just did try to cancel and nothing happened, everything works fine.

That is truly remarkable, with your existing code.

            fname5, _ = QFileDialog.getOpenFileName(self, "Choose File", "", "All Files(*) ;; Images(*.jpeg)")
            pixmap = QPixmap(fname5, _)

So after the user clicks Cancel in the dialog, what is returned in fname5 and most importantly what in your code stops so that it does not try to load a QPixmap? Or do you mean it just seems to be OK when you continue ignoring the Cancel and try to load a QPixmap from "nothing"? Try first running this and picking a suitable file to load, then re-running it and pressing Cancel, that leaves the currently loaded pixmap as-is, does it?

@jsulm Yes I'm using SQL.

@JonB Oh! my bad. I meant when user clicks on the cancel the dialog window exits.

[JonB]

@LT-K101
Now I'm really lost. From the QFileDialog clicking either Cancel or selecting a file and clicking OK should close/exit that dialog window. Originally you said

but my application exits as soon as i click on open file

If you want help can you please state clearly whether this is still the case and/or when your application exits upon closing the file dialog.

@JonB @JonB Any help on how to display only file name instead of displaying file full path using the QFileDialog? Thanks in advance. Below is my code.

    
def Load_First_Certificate(self):
        self.fname1, ok = QFileDialog.getOpenFileName(self, "Upload Pdf File", "", "Pdf Files(*.pdf)")

        if ok:
            defaultPdf = os.path.split(self.fname1)
            self.ui.Pdf_lineEdit.setText(self.fname1)

@LT-K101 If you look at the QString (or str in Python) documentation you will surely notice that there is split() method. So self.fname1.split('/').last() should do the trick. Why don't read documentation on the basic types you use?

[JonB]

@LT-K101

print(QFile(self.fname1).fileName())
print(QFileInfo(self.fname1).fileName())

Your code:

        self.fname1, ok = QFileDialog.getOpenFileName(self, "Upload Pdf File", "", "Pdf Files(*.pdf)")
        if ok:

Where do you get the idea that the second result is any kind of ok parameter, and that you should be looking at it for success?

@LT-K101

self.ui.Pdf_lineEdit.setText(os.path.basename(self.fname1))

@jsulm
You are encouraging OP to mix native Python calls with Qt calls when no need to, grrr! Since QFileDialog.getOpenFileName() returns a Qt-type-path (right?), he must now go check up how os.path.... handles e.g. /s under Windows....

@JonB Sorry that was a function i wrote for my image upload function, if user does not upload an image then the default image should be an avatar. I copied it and forgot to delete the if statement. Thanks

@jsulm Thanks it's working! After selecting the pdf file saving to a location in my working directory is the problem now. Any assistance please?

Any assistance please?

Please ask a concrete question. What is the concrete problem you're having now?

[LT-K101]

@jsulm I want to save the uploaded file itself to a specific directory not just the filename. Example when the user click on open button to select file , after user select file. The file should be saved in a directory.

[jsulm]

@LT-K101 Then do so: https://doc.qt.io/qt-5/qfile.html

@jsulm Thanks
