The self argument may > or may not be needed, its been a while since ive used Qt. getOpenFileName is a static method. The first parameter is the [optional] parent widget. The documentation says the dialog should be centered over the parent, but it probably won't be if you let it use the default native dialog. This can be disabled with the option QFileDialog.DontUseNativeDialog. For example: path = QtGui.QFileDialog.getOpenFileName( parent=self, caption='File Dialog', directory='path/to/open', filter='type1 (*.ext1);;type2 (*.ext2)', selectedFilter='type2 (*.ext2)', options=QFileDialog.DontUseNativeDialog, ) http://pyqt.sourceforge.net/Docs/PyQt4/qfiledialog.html#getOpenFileName http://pyqt.sourceforge.net/Docs/PyQt4/qfiledialog.html#Option-enum ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Yes, the following works. path = QtGui.QFileDialog.getOpenFileName() Thanks!

No problem. to do it without the instance variable, you access its method directly. so replace: path = self.fileDialog.getOpenFileName() with path = QFileDialog.getOpenFileName(self) which is basically the same thing except you're going to the method directly instead of creating a class instance.

Re: [Tutor] Fwd: QT Python: How to re-use the return value of fileDialog.openFileName() ?
Thanks!
I defined a function, as you suggested, to call when the button was
clicked. But then I also had to use self.fileDialog from within the
function. Not sure how I could avoid using fileDialog.
I also defined global variable (under the class) and assigned it to the
filename, so I could access it from within the main class.
The following works:
QtCore.QObject.connect(self.toolButton,
QtCore.SIGNAL(_fromUtf8("clicked()")), self.getFileName)
def getFileName(self):
self.fileDialog = QtGui.QFileDialog()
path = self.fileDialog.getOpenFileName()
print(" File Selected: ", path)
self.lineEdit.setText(path)
self.XmlFileName = path
Thanks.

i think the way youre doing it won't allow you to get the filename as
you are calling it through a signal.
Things you can do:
1) dont use self.fileDialog.getOpenFileName as a slot like you are
doing. Create a function and call it when the toolbar's button is
clicked, then in that function assign the filename to the return value
of self.fileDialog.getOpenFileName.
2) if the only thing your self.fileDialog is doing is responding to
the toolbar's button, don't create it at all. do what i said in #1 and
assign a filename variable to the full method of the dialog. What im
saying is there might be no need to create the self.fileDialog
instance variable at all.
