According to getOpenFileName instructions:
QString fileName = QFileDialog.getOpenFileName(this, tr("Open File"),
"/home",
tr("Images (*.png *.xpm *.jpg)"));
How can I make the dialog remember the path the last time when I close it?
and what does the tr mean in the tr("Open File")
?
Thanks
If you omit the dir
argument (or pass in an empty string), the dialog should remember the last directory:
filename = QtGui.QFileDialog.getOpenFileName(
parent, 'Open File', '', 'Images (*.png *.xpm *.jpg)')
The tr function is used for translating user-visible strings. You can omit it if you won't ever be providing translations for your application.
EDIT:
It seems that the start directory may not be automatically remembered on all platforms/desktops, depending on whether you use the native dialog or not. If Qt's built-in dialog is used, the start directory should always be automatically remebered on all platforms (even between invokations of the application). To try the non-native dialog, do:
filename = QtGui.QFileDialog.getOpenFileName(
parent, 'Open File', '', 'Images (*.png *.xpm *.jpg)',
None, QtGui.QFileDialog.DontUseNativeDialog)
Alternatively, you can use the QFileDialog constructor, which will always create a non-native dialog:
dialog = QtGui.QFileDialog(parent)
dialog.setWindowTitle('Open File')
dialog.setNameFilter('Images (*.png *.xpm *.jpg)')
dialog.setFileMode(QtGui.QFileDialog.ExistingFile)
if dialog.exec_() == QtGui.QDialog.Accepted:
filename = dialog.selectedFiles()[0]
