python - 将 .ui 转换为包含升级框架的 .py 文件

Question

我有一个.h file，它对应的.cpp file是一个频率 Controller 小部件。我可以通过将 Qframe 小部件提升到该 .h 文件来在 QtCreator 和 C++ 中使用它，没有任何问题。但我想在 QTDesigner 中构建一个 UI 并使用 pyuic5 将其转换为 python。当然，pyuic5无法理解c++代码，甚至在.ui文件中没有任何线索或指向.cpp文件的链接!那么如何将包含升级的 QFrame 的表单转换并使用 python 代码并在 pyqt 应用程序中使用它？

这是我设计的简单用户界面，我想使用 pyuic5 将其转换为 python

pyuic 只是一个将 .ui 转换为 .py 的工具，因此他通过生成以下内容来完成此操作:

pyuic5 file.ui -o file_ui.py -x

file_ui.py

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'file.ui'
#
# Created by: PyQt5 UI code generator 5.12.1
#
# 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(456, 280)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.freqCtrl = CFreqCtrl(self.centralwidget)
        self.freqCtrl.setGeometry(QtCore.QRect(80, 70, 280, 40))
        sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Fixed, QtWidgets.QSizePolicy.Fixed)
        sizePolicy.setHorizontalStretch(0)
        sizePolicy.setVerticalStretch(0)
        sizePolicy.setHeightForWidth(self.freqCtrl.sizePolicy().hasHeightForWidth())
        self.freqCtrl.setSizePolicy(sizePolicy)
        self.freqCtrl.setMinimumSize(QtCore.QSize(280, 40))
        self.freqCtrl.setToolTip("")
        self.freqCtrl.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.freqCtrl.setFrameShadow(QtWidgets.QFrame.Raised)
        self.freqCtrl.setObjectName("freqCtrl")
        MainWindow.setCentralWidget(self.centralwidget)

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

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


from freqctrl import CFreqCtrl


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

正如您所看到的，它具有以下指令 from freqctrl import CFreqCtrl 指示您要导入应位于 freqctrlv.py 文件中的 CFreqCtrl 类。

PyQt5 或 pyuic5 无法理解 C++ 代码，因此您的任务是手动将 C++ 代码移植到 python，另一个选项是使用 SIP 创建绑定(bind)，请使用第一个选项:
