Pycharm+Python+PyQt5使用

#pip install pyqt5#pip install pyqt5-tools

配置环境

pycharm目录栏file>settings>tools>external tools 将QtDesigner和PyUIC链接到PyCharm的外部工具库 点击+添加 配置programs，和working directory 按同样的方法添加UIC 配置program， arguments： -m PyQt5.uic.pyuic -o $FileNameWithoutExtension$.py $FileName$ working directory。

设置完成后就可以在PyCharm的Tools->External Tools菜单下看到我们新添加的工具了

新建QT designer，方法PyCharm的Tools->External Tools>UI

点击保存 鼠标右键选择external tools>UIC将ui文件转换成py文件

from PyQt5 import QtCore, QtGui, QtWidgetsclass Ui_MainWindow(object):    def setupUi(self, MainWindow):        MainWindow.setObjectName("MainWindow")        MainWindow.resize(321, 380)        self.centralwidget = QtWidgets.QWidget(MainWindow)        self.centralwidget.setObjectName("centralwidget")        self.pushButton = QtWidgets.QPushButton(self.centralwidget)        self.pushButton.setGeometry(QtCore.QRect(90, 280, 75, 23))        self.pushButton.setObjectName("pushButton")        self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget)        self.pushButton_2.setGeometry(QtCore.QRect(190, 280, 75, 23))        self.pushButton_2.setObjectName("pushButton_2")        self.label = QtWidgets.QLabel(self.centralwidget)        self.label.setGeometry(QtCore.QRect(120, 70, 281, 61))        font = QtGui.QFont()        font.setFamily("新宋体")        font.setPointSize(18)        self.label.setFont(font)        self.label.setMouseTracking(True)        self.label.setObjectName("label")        self.label_2 = QtWidgets.QLabel(self.centralwidget)        self.label_2.setGeometry(QtCore.QRect(60, 200, 54, 12))        self.label_2.setObjectName("label_2")        self.label_3 = QtWidgets.QLabel(self.centralwidget)        self.label_3.setGeometry(QtCore.QRect(60, 240, 54, 12))        self.label_3.setObjectName("label_3")        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)        self.lineEdit.setGeometry(QtCore.QRect(110, 200, 113, 20))        self.lineEdit.setObjectName("lineEdit")        self.lineEdit_2 = QtWidgets.QLineEdit(self.centralwidget)        self.lineEdit_2.setGeometry(QtCore.QRect(110, 240, 113, 20))        self.lineEdit_2.setObjectName("lineEdit_2")        MainWindow.setCentralWidget(self.centralwidget)        self.menubar = QtWidgets.QMenuBar(MainWindow)        self.menubar.setGeometry(QtCore.QRect(0, 0, 321, 23))        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.translate        MainWindow.setWindowTitle(_translate("MainWindow", "myWindow"))        self.pushButton.setText(_translate("MainWindow", "取消"))        self.pushButton_2.setText(_translate("MainWindow", "确定"))        self.label.setText(_translate("MainWindow", "用户登录"))        self.label_2.setText(_translate("MainWindow", "用户名："))        self.label_3.setText(_translate("MainWindow", "密  码："))

这个py文件只有定义珠光扣以及起空间的代码，并没有程序入口的代码，如要显示窗口，在末位增添代码如下：

import sysfrom PyQt5.QtWidgets import QApplication,QMainWindowclass Mywindow(QMainWindow,Ui_MainWindow):    def __init__(self,parent=None):        super(Mywindow,self).__init__(parent)        self.setupUi(self)if __name__ == '__main__':    app = QApplication(sys.argv)    ex = Mywindow()    ex.show()    sys.exit(app.exec())
