- 2.多个文件打开 QFileDialog.getOpenFileNames()
- 3.文件夹选取 QFileDialog.getExistingDirectory()
- 4.文件保存 QFileDialog.getSaveFileName()

二、实例代码:
- from PyQt5 import QtWidgets
- from PyQt5.QtWidgets import QFileDialog
-
- class MyWindow(QtWidgets.QWidget):
- def __init__(self):
- super(MyWindow,self).__init__()
- self.myButton = QtWidgets.QPushButton(self)
- self.myButton.setObjectName("myButton")
- self.myButton.setText("Test")
- self.myButton.clicked.connect(self.msg)
-
- def msg(self):
- directory1 = QFileDialog.getExistingDirectory(self,
- "选取文件夹",
- "./") #起始路径
- print(directory1)
-
- fileName1, filetype = QFileDialog.getOpenFileName(self,
- "选取文件",
- "./",
- "All Files (*);;Text Files (*.txt)") #设置文件扩展名过滤,注意用双分号间隔
- print(fileName1,filetype)
-
- files, ok1 = QFileDialog.getOpenFileNames(self,
- "多文件选择",
- "./",
- "All Files (*);;Text Files (*.txt)")
- print(files,ok1)
-
- fileName2, ok2 = QFileDialog.getSaveFileName(self,
- "文件保存",
- "./",
- "All Files (*);;Text Files (*.txt)")
-
- if __name__=="__main__":
- import sys
-
- app=QtWidgets.QApplication(sys.argv)
- myshow=MyWindow()
- myshow.show()
- sys.exit(app.exec_())
