我目前在qt gui界面中有一个textEdit小部件。 在Linux中，我可以从系统中拖放文件到文件中，并用“file：/// path / to / file”填充该部件。 文件：//部分有点烦人，但我可以筛选出来。 但是，当我尝试从Windows拖放文件时，小部件完全拒绝。 我怎样才能让它接受Windows文件？
主要的python文件与相关的代码：
import os #to get current working directory import sys from ui import Ui_Form #Ui_Form contains the code for the display. Generated by QT Designer from PyQt4 import QtCore, QtGui #code for Qt class UI(Ui_Form): def setupUi(self, Form): super().setupUi(Form) self.browseButton.clicked.connect(self.browse) def browse(self): self.lineEdit.setText(QtGui.QFileDialog.getOpenFileName(self.lineEdit, "Open File", os.getcwd(), "CSV (*.csv)") ) app = QtGui.QApplication(sys.argv) Form = QtGui.QWidget() ui = UI() ui.setupUi(Form) Form.show() sys.exit(app.exec_()) 下面的代码是用QTDesigner生成的：
# -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'interface.ui' # # Created by: PyQt4 UI code generator 4.11.4 # # WARNING!
