Multiple files and folder selection in QFileDialog (Revisited)

Question

This question already exists here , but the answer seems outdated or no longer works with Python 2.7.

When I use this code to subclass my QFileDialog, the initDialog init class is called, but the openClicked method is never called.

class FileDialog(QtGui.QFileDialog): def __init__(self, *args): QtGui.QFileDialog.__init__(self, *args) self.setOption(self.DontUseNativeDialog, True) self.setFileMode(self.ExistingFiles) btns = self.findChildren(QtGui.QPushButton) self.openBtn = [x for x in btns if 'open' in str(x.text()).lower()][0] self.openBtn.clicked.disconnect() self.openBtn.clicked.connect(self.openClicked) self.tree = self.findChild(QtGui.QTreeView) def openClicked(self): inds = self.tree.selectionModel().selectedIndexes() files = [] for i in inds: if i.column() == 0: files.append(os.path.join(str(self.directory().absolutePath()),str(i.data().toString()))) self.selectedFiles = files self.hide() def filesSelected(self): return self.selectedFiles 

Is this the correct call to FileDialog?

 mydialog = FileDialog() filelist = mydialog.getExistingDirectory(self, "Select Stuff", "", QtGui.QFileDialog.DontConfirmOverwrite) 

Answer 1

The decision on another issue is unnecessarily complicated. All you have to do is override QFileDialog.accept() and then you can implement any behavior you like.

The example below is very minimal. It does not perform any checks on the selected files (for example, see whether they still exist), but it can be easily added if necessary.

 from PyQt4 import QtCore, QtGui class FileDialog(QtGui.QFileDialog): def __init__(self, *args, **kwargs): super(FileDialog, self).__init__(*args, **kwargs) self.setOption(QtGui.QFileDialog.DontUseNativeDialog, True) self.setFileMode(QtGui.QFileDialog.ExistingFiles) def accept(self): super(FileDialog, self).accept() class Window(QtGui.QWidget): def __init__(self): super(Window, self).__init__() self.button = QtGui.QPushButton('Test', self) self.button.clicked.connect(self.handleButton) layout = QtGui.QVBoxLayout(self) layout.addWidget(self.button) def handleButton(self): dialog = FileDialog() if dialog.exec_() == QtGui.QDialog.Accepted: print(dialog.selectedFiles()) if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) window = Window() window.show() sys.exit(app.exec_())
