App crashed while browsing PST files

[praneshpk]

@jsulm @JonB I have another doubt. Now using this code I'm able to load only one file. How can I select all files or a specific folder? Can you help me with this?

[jsulm]

@praneshpk Get all files in the folder using https://doc.qt.io/qt-5/qdir.html#entryList-1 and iterate over these files...

[praneshpk]

Instead of

 QtWidgets.QFileDialog.getOpenFileName

I have given

 QtWidgets.QFileDialog.getOpenFileNames

I am able to select many files but it is not reflected in lineedit.

[jsulm]

@praneshpk said in App crashed while browsing PST files:

I am able to select many files but it is not reflected in lineedit.

Please show the code...

Well that is up to your code. getOpenFileNames() returns a list of filenames, what you do with that like putting it into a QLineEdit or QListView or whatever is up to you.

[praneshpk]

def returnPressedSlot( self ):
    ''' Called when the user enters a string in the line edit and
    presses the ENTER key.
    '''
    fileName =  self.lineEdit.text()


# slot
def browseSlot( self ):
    ''' Called when the user presses the Browse button
    '''
    #self.debugPrint( "Browse button pressed" )
    options = QtWidgets.QFileDialog.Options()
    options |= QtWidgets.QFileDialog.DontUseNativeDialog
    fileName, _ = QtWidgets.QFileDialog.getOpenFileName(
                    None,
                    "QFileDialog.getOpenFileName()",
                    "",
                    "All Files (*);;Python Files (*.py)",
                    options=options)
    if fileName:
        #self.debugPrint( "setting file name: " + fileName )
        self.model.setFileName( fileName )
        self.refreshAll()

what happens is when I use getfilename single file name is loaded and displayed. when I get many files using getfilenames it is creating a list. That list is not reflected in line edit (here linedit function is returnedpresses slot). how to get that name inside a list and display in lineedit

[JonB]

@praneshpk
This is just a Python issue. If you have a list in Python you use join() to turn it into a string, don't you? E.g.

print(" ".join(filenames))

[praneshpk]

@JonB have tired that it is not working

[jsulm]

@praneshpk Please show the code, not just "is not working". And in what way it did not work?

[praneshpk]

@jsulm I thought you would refer code that I have added at the starting of discussion. I will attach the code below.

@praneshpk Where in this code do you get a list of files, do the join (as @JonB suggested) and then set the label?!
I only see your old QtWidgets.QFileDialog.getOpenFileName to get ONE file, not a list?
Did you try it at all?!
I also asked only for the relevant code, not the whole code!
