使用python3+PyQt5+PyCharm桌面GUI开发

发表于 | 更新于 | 评论数： | 阅读次数：

下面简单介绍基于Python3、PyQt5和PyCharm进行桌面GUI开发。

环境配置

安装python3

PyQt5所支持的python版本是从3.5开始的，因此安装的Python3版本必须大于3.5。

安装PyQt5

2
pip3 install PyQt5
pip3 install PyQt5-tools

安装PyCharm

安装完PyCharm后，需要配置Qt Designer和PyUIC，前者用于设计UI，后者用于将UI转成Py文件。

具体步骤请参考程序员之路：python3+PyQt5+pycharm桌面GUI开发。

        self.lineEdit_ExtName.setGeometry(QtCore.QRect(100, 112, 281, 21))
        self.lineEdit_ExtName.setObjectName("lineEdit_ExtName")

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

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.label_DirPath.setText(_translate("Form", "文件路径："))

# 下面代码是手动添加的
if __name__=="__main__":
    import sys
    from PyQt5.QtGui import QIcon
    app=QtWidgets.QApplication(sys.argv)
    widget=QtWidgets.QWidget()
    ui=Ui_Form()
    ui.setupUi(widget)
    # widget.setWindowIcon(QIcon('web.png'))#增加icon图标，如果没有图片可以没有这句
    widget.show()
    sys.exit(app.exec_())
