要选择多个文件，必须使用QFileDialog::getOpenFileNames

示例1:

from PyQt4 import QtCore, QtGui

if __name__ == '__main__':
    import sys
    app = QtGui.QApplication(sys.argv)
    filenames = QtGui.QFileDialog.getOpenFileNames()
    print(filenames)
    sys.exit(app.exec_())

示例2:

from PyQt4 import QtCore, QtGui

if __name__ == '__main__':
    import sys
    app = QtGui.QApplication(sys.argv)
    filenames = QtGui.QFileDialog.getOpenFileNames(None,
        "Select one or more files to open",
        QtCore.QDir.homePath(),
        "Images (*.png *.xpm *.jpg)")
    print(filenames)
    sys.exit(app.exec_())
