Answer 1

In Qt5 you can simply use

return QtWidgets.QFileDialog.getOpenFileNames(self, title, directory, filter=filterFile)

Answer 2

Here's a hack that should work for you: Create a subclass of QFileDialog that disconnects the "Open" button and reconnects it to a customized function. It's not guaranteed to work across different versions of Qt, though, since it relies on being able to find specific sub-widgets that may be reconfigured at some point.

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
