一、方法 1.单个文件打开
QFileDialog.getOpenFileName()
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import sys
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__":
app=QtWidgets.QApplication(sys.argv)
myshow=MyWindow()
myshow.show()
sys.exit(app.exec_())
