Python 有没有办法在pyqt5中显示“帮助”选项卡？

我正在为我在pyqt5中的拼贴项目编写代码，在那里我需要制作一个帮助选项卡。我计划使帮助内容智能化，因为大多数软件都有，如下图所示（onlyoffice的帮助）。有没有办法写得容易些

这种显示标题栏中嵌入多个“选项卡”的界面的问题在于，使用Qt不容易实现，而您应该手动实现整个标题栏，这并不容易

如果您正在寻找一个更简单的解决方案，我建议使用一个QTabWidget，如果只有一个选项卡，它不会显示选项卡栏。如果您尚未使用带有可关闭选项卡的选项卡式界面，则可以将选项卡小部件设置为允许可关闭选项卡，并覆盖默认方法，以便在不需要关闭按钮时隐藏关闭按钮

class TabWidget(QtWidgets.QTabWidget):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.setDocumentMode(True)
        self.setTabsClosable(True)
        self.tabCloseRequested.connect(self.removeTab)
        self.tabBar().hide()

    def addTab(self, *args, **kwargs):
        self.insertTab(-1, *args, **kwargs)

    def insertTab(self, *args, **kwargs):
        super().insertTab(*args)
        closable = kwargs.get('closable', False)
        if not closable:
            index = args[0]
            if index < 0:
                index = self.count() - 1
            for side in QtWidgets.QTabBar.LeftSide, QtWidgets.QTabBar.RightSide:
                widget = self.tabBar().tabButton(index, side)
                if isinstance(widget, QtWidgets.QAbstractButton):
                    self.tabBar().setTabButton(index, side, None)
                    break
        self.tabBar().setVisible(self.count() > 1)

    def removeTab(self, index):
        super().removeTab(index)
        self.tabBar().setVisible(self.count() > 1)


class MainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.tabWidget = TabWidget()
        self.setCentralWidget(self.tabWidget)

        self.main = QtWidgets.QWidget()
        self.tabWidget.addTab(self.main, 'My program')
        layout = QtWidgets.QGridLayout(self.main)

        someButton = QtWidgets.QPushButton('Some button')
        layout.addWidget(someButton, 0, 0)

        layout.addWidget(QtWidgets.QLabel('Some label'), 0, 1)

        helpButton = QtWidgets.QPushButton('Show help!')
        layout.addWidget(helpButton, 0, 2)

        textEdit = QtWidgets.QTextEdit()
        layout.addWidget(textEdit, 1, 0, 1, 3)

        self.helpTab = QtWidgets.QTextBrowser()
        self.helpTab.setHtml('Hello, this is <b>help</b>!')

        helpButton.clicked.connect(self.showHelp)

    def showHelp(self):
        for i in range(self.tabWidget.count()):
            if self.tabWidget.widget(i) == self.helpTab:
                break
        else:
            self.tabWidget.addTab(self.helpTab, 'Help!', closable=True)
        self.tabWidget.setCurrentWidget(self.helpTab)
        self.tabWidget.tabBar().show()

谢谢@musicamante，很抱歉回复太晚。这对我来说太难理解了。你有一个简单的解决方案吗？就像我有一个PDF文件，里面包含了帮助的所有主题。如何合并该文件？@ParthPatel使用qspliter作为中心小部件并添加pdf查看器，或者使用QDockWidget。

NoWhatsThisText = '__NoWhatsThis'
NoWhatsThisValue = 'There is no help for this object'
HelpData = {
    NoWhatsThisText: NoWhatsThisValue, 
    'someButton': 'Do something with the button', 
    'helpButton': 'Click the button to show this help', 
    'textEdit': 'Type <b>some text</b> to <i>read</i> it', 
    'mainWindow': 'A main window is cool!', 
}

            whatsThis = source.whatsThis()
            while whatsThis == NoWhatsThisText:
                if not source.parent():
