按照自己思路简单写了个桌面播放器，只有自己喜欢的歌。使用QtDesigner设计的ui界面，功能简单，还有很多bug@~@，代码奉上：
music_button.ui使用扩展工具pyuic5生成了music_button.py文件，内容如下：
# -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'music_button.ui' # # Created by: PyQt5 UI code generator 5.11.3 # # WARNING! All changes made in this file will be lost! from PyQt5 import QtCore, QtGui, QtWidgets class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow.resize(265, 65) MainWindow.setMinimumSize(QtCore.QSize(265, 65)) MainWindow.setMaximumSize(QtCore.QSize(265, 169)) self.centralwidget = QtWidgets.QWidget(MainWindow) self.centralwidget.setObjectName("centralwidget") self.pushButton = QtWidgets.QPushButton(self.centralwidget) self.pushButton.setGeometry(QtCore.QRect(60, 10, 24, 24)) self.pushButton.setAutoFillBackground(False) self.pushButton.setStyleSheet("border-image: url(:/qrc_files/up.png);") self.pushButton.setText("") self.pushButton.setAutoDefault(False) self.pushButton.setObjectName("pushButton") self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget) self.pushButton_2.setGeometry(QtCore.QRect(110, 10, 24, 24)) self.pushButton_2.setStyleSheet("border-image: url(:/qrc_files/play.png);") self.pushButton_2.setText("") self.pushButton_2.status = 0 self.pushButton_2.setObjectName("pushButton_2") self.pushButton_3 = QtWidgets.QPushButton(self.centralwidget) self.pushButton_3.setGeometry(QtCore.QRect(160, 10, 24, 24)) self.pushButton_3.setStyleSheet("border-image: url(:/qrc_files/down.png);") self.pushButton_3.setText("") self.pushButton_3.setObjectName("pushButton_3") MainWindow.setCentralWidget(self.centralwidget) self.statusbar = QtWidgets.QStatusBar(MainWindow) self.statusbar.setObjectName("statusbar") MainWindow.setStatusBar(self.statusbar) self.menubar = QtWidgets.QMenuBar(MainWindow) self.menubar.setGeometry(QtCore.QRect(0, 0, 265, 23)) self.menubar.setObjectName("menubar") MainWindow.setMenuBar(self.menubar) self.retranslateUi(MainWindow) self.pushButton.clicked.connect(self.pushButton_1_click) self.pushButton_2.clicked.connect(self.pushButton_2_click) self.pushButton_3.clicked.connect(self.pushButton_3_click) QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi(self, MainWindow): _translate = QtCore.QCoreApplication.translate MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow")) def pushButton_1_click(self): pass def pushButton_2_click(self): pass def pushButton_3_click(self): pass from qrc_files import down from qrc_files import play from qrc_files import up
上面引入qrc文件，需要自己使用扩展工具pyrcc将图片资源转为python文件再引入，qrc文件内容如下：
<RCC> <qresource prefix="qrc_files/"> <file>down.png</file> </qresource> </RCC>
以下是down.png生成的down.py文件：
