pyqt5使用Designer实现按钮上传图片

1、ui界面

在这里插入图片描述

2、ui转py代码

其中uploadimg.py代码如下：

# -*- coding: utf-8 -*-# Form implementation generated from reading ui file 'uploadimg.ui'
#
# Created by: PyQt5 UI code generator 5.15.4
#
# 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.from PyQt5 import QtCore, QtGui, QtWidgetsclass Ui_MainWindow(object):def setupUi(self, MainWindow):MainWindow.setObjectName("MainWindow")MainWindow.resize(800, 600)self.centralwidget = QtWidgets.QWidget(MainWindow)self.centralwidget.setObjectName("centralwidget")self.img_show = QtWidgets.QLabel(self.centralwidget)self.img_show.setGeometry(QtCore.QRect(41, 50, 711, 351))self.img_show.setObjectName("img_show")self.label_2 = QtWidgets.QLabel(self.centralwidget)self.label_2.setGeometry(QtCore.QRect(30, 10, 72, 15))self.label_2.setObjectName("label_2")self.label_3 = QtWidgets.QLabel(self.centralwidget)self.label_3.setGeometry(QtCore.QRect(50, 430, 41, 31))self.label_3.setObjectName("label_3")self.img_path = QtWidgets.QLineEdit(self.centralwidget)self.img_path.setGeometry(QtCore.QRect(100, 430, 371, 31))self.img_path.setObjectName("img_path")self.btn_upload = QtWidgets.QPushButton(self.centralwidget)self.btn_upload.setGeometry(QtCore.QRect(480, 430, 93, 28))self.btn_upload.setObjectName("btn_upload")self.img_list = QtWidgets.QComboBox(self.centralwidget)self.img_list.setGeometry(QtCore.QRect(100, 480, 371, 31))self.img_list.setObjectName("img_list")self.label_4 = QtWidgets.QLabel(self.centralwidget)self.label_4.setGeometry(QtCore.QRect(30, 480, 61, 31))self.label_4.setObjectName("label_4")self.btn_sure = QtWidgets.QPushButton(self.centralwidget)self.btn_sure.setGeometry(QtCore.QRect(480, 480, 93, 28))self.btn_sure.setObjectName("btn_sure")self.btn_next = QtWidgets.QPushButton(self.centralwidget)self.btn_next.setGeometry(QtCore.QRect(590, 480, 93, 28))self.btn_next.setObjectName("btn_next")MainWindow.setCentralWidget(self.centralwidget)self.menubar = QtWidgets.QMenuBar(MainWindow)self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 27))self.menubar.setObjectName("menubar")MainWindow.setMenuBar(self.menubar)self.statusbar = QtWidgets.QStatusBar(MainWindow)self.statusbar.setObjectName("statusbar")MainWindow.setStatusBar(self.statusbar)self.retranslateUi(MainWindow)QtCore.QMetaObject.connectSlotsByName(MainWindow)def retranslateUi(self, MainWindow):_translate = QtCore.QCoreApplication.translateMainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))self.img_show.setText(_translate("MainWindow", "图片"))self.label_2.setText(_translate("MainWindow", "图片"))self.label_3.setText(_translate("MainWindow", "路径"))self.btn_upload.setText(_translate("MainWindow", "加载"))self.label_4.setText(_translate("MainWindow", "图片列表"))self.btn_sure.setText(_translate("MainWindow", "确定"))self.btn_next.setText(_translate("MainWindow", "下一张"))

3、upload_main.py主函数代码

upload_main.py代码如下：
