PyQt5 将.ui文件转为.py文件并用另一个.py调用-Toy模板网

这篇具有很好参考价值的文章主要介绍了PyQt5 将.ui文件转为.py文件并用另一个.py调用。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

一、.ui转.py

1.使用终端进入ui文件所在的文件夹

值得注意的是，Anaconda Prompt不能直接cd进其它盘

需要在根目录下进行切换盘符操作，使用 cd ..切进上一级目录，直到进入根目录：

这样就可以了

2.输入以下命令：

pyuic5 -o UI.py UI.ui

代码说明

生成的py文件：

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'UI.ui'
#
# Created by: PyQt5 UI code generator 5.15.7
#
# WARNING: Any manual changes made to this file will be lost when pyuic5 is
# run again.  Do not edit this file unless you know what you are doing.

        self.retranslateUi(Gaze_Estimation)
        QtCore.QMetaObject.connectSlotsByName(Gaze_Estimation)

    def retranslateUi(self, Gaze_Estimation):
        _translate = QtCore.QCoreApplication.translate
        Gaze_Estimation.setWindowTitle(_translate("Gaze_Estimation", "Form"))
        self.label_predictor.setText(_translate("Gaze_Estimation", "<html><head/><body><p><span style=\" font-size:11pt;\">Predictor:</span></p></body></html>"))
        self.pushButton_predictor.setText(_translate("Gaze_Estimation", "选择文件"))
        self.label_gaze_model.setText(_translate("Gaze_Estimation", "<html><head/><body><p><span style=\" font-size:11pt;\">Gaze model:</span></p></body></html>"))
        self.pushButton_gaze_model.setText(_translate("Gaze_Estimation", "选择文件"))
        self.label_pnet_model.setText(_translate("Gaze_Estimation", "<html><head/><body><p><span style=\" font-size:11pt;\">Pnet model:</span></p></body></html>"))
        self.pushButton_pnet_model.setText(_translate("Gaze_Estimation", "选择文件"))
        self.label_rnet_model.setText(_translate("Gaze_Estimation", "<html><head/><body><p><span style=\" font-size:11pt;\">Rnet model:</span></p></body></html>"))
        self.pushButton_rnet_model.setText(_translate("Gaze_Estimation", "选择文件"))
        self.label_onet_mobel.setText(_translate("Gaze_Estimation", "<html><head/><body><p><span style=\" font-size:11pt;\">Onet model:</span></p></body></html>"))
        self.pushButton_onet_model.setText(_translate("Gaze_Estimation", "选择文件"))
        self.label_device.setText(_translate("Gaze_Estimation", "<html><head/><body><p><span style=\" font-size:11pt;\">Device:</span></p></body></html>"))
        self.pushButton_device.setText(_translate("Gaze_Estimation", "选择文件"))

二、用另一个py文件调用展示ui

import sys

from PyQt5.QtWidgets import *

from UI import Ui_Gaze_Estimation


class MyWindow(QWidget, Ui_Gaze_Estimation):
    def __init__(self):
        super(MyWindow, self).__init__()
        self.setupUi(self)
        self.retranslateUi(self)


if __name__ == "__main__":
    app = QApplication(sys.argv)

    w = MyWindow()
    # 展示窗口
    w.show()

    app.exec()

运行代码即可成功展示UI界面：
