QPixmap简介

QPixmap类用于绘图设备的图像显示，它可以作为一个QPainterDevice对象，也可以加载到一个控件中，通常是标签或者按钮，用于在标签或按钮上显示图像QPixmap可以读取的图像文件类型有BMP，GIF，JPG等。

import sys

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(270, 180, 241, 101))
        self.label.setText("")
        self.label.setPixmap(QtGui.QPixmap(":/img/logo.png"))
        self.label.setObjectName("label")
        MainWindow.setCentralWidget(self.centralwidget)

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

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))


if __name__ == '__main__':
    import resource  # 导入添加的资源（根据实际情况填写文件名）
    app = QApplication(sys.argv)
    MainWindow = QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

 需要向PyUIC 生成的代码，添加如下代码片段:

追加资源文件

import resource  # 导入添加的资源（根据实际情况填写文件名）
