解决pyqt5 textbrowser控件超链接锚点问题

引用stackoverflow的一篇文章，我解决了pyqt5 textbrowser控件超链接锚点问题，
文章链接：https://stackoverflow.com/questions/73584865/qtextbrowser-pyqt5-problem-after-click-on-anchor

主要解决方案：每次在textbrowser控件中使用append添加内容(包含超链接内容)之前，将游标移动到textbrowser控件的最下方，即可以解决问题。

'''This might be unintuitive for QTextBrowser, since it doesn't show the text cursor (the "caret"), but clicking on a QTextBrowser does change the cursor position, exactly like it would if you used setReadOnly(False) or by using a standard QTextEdit.

The solution is to always move the text cursor to the end before calling append(). Remember that in order to make the actual text edit/browser cursor move, you must call setTextCursor() again after moving its position.'''

    def addtxt(self):
        # get the QTextCursor of the widget's document
        cursor = self.browser.textCursor()
        # move it to the end of the document
        cursor.movePosition(cursor.End)
        # *restore* the text cursor on the widget
        self.browser.setTextCursor(cursor)

        self.browser.append('sample text 1')
        self.browser.append('some text: <a href="http://link.com">textlink</a>')
        self.browser.append('sample text 2')

现象描述如下:
源代码：

import sys
from PyQt5.QtWidgets import *


class MainWindow(QMainWindow):

    def __init__(self):
        QMainWindow.__init__(self)
        self.resize(500, 500)
        self.browser = QTextBrowser(self)
        self.browser.resize(500, 300)
        self.btn = QPushButton('get html print', self)
        self.btn.move(250, 400)
        self.btn.clicked.connect(self.gethtml)
        self.btn2 = QPushButton('add text', self)
        self.btn2.move(150, 400)
        self.btn2.clicked.connect(self.addtxt)
        self.browser.setOpenLinks(False)
        self.browser.anchorClicked.connect(self.anchor_clicked)

    def gethtml(self):
        print(self.browser.toHtml())

    def addtxt(self):
        self.browser.append('sample text 1')
        self.browser.append('some text: <a href="http://link.com">textlink</a>')
        self.browser.append('sample text 2')

    def anchor_clicked(self):
        pass


if __name__ == '__main__':
    app = QApplication(sys.argv)
    dlgMain = MainWindow()
    dlgMain.show()
    sys.exit(app.exec_())

点击界面上"add text"按钮后，显示结果如下图：

在textbrowser控件显示超链接文本内容之后，点击textlink链接锚点会打开对应的链接，
点击之后，再点击"add text"按钮后会变成如下效果, 没有设置超链接的文本也激活了超链接锚点，

贴出我的代码：

    self.button2.clicked.connect(self.getaccounts)

def getaccounts(self):
        # 启动进度条动画
        self.progress_bar.setRange(0, 0)
        self.progress_timer.start(100)

        # 禁用按钮防止重复点击
        self.button1.setEnabled(False)
        self.button2.setEnabled(False)
        self.scrolledtext1.setReadOnly(True)

        # 创建工作线程
        self.worker = WorkerThread(self._do_getaccounts)
        self.worker.finished.connect(self.on_getaccounts_finished)
        self.worker.start()

def on_getaccounts_finished(self, success, result):
        # 恢复按钮状态
        self.button1.setEnabled(True)
        self.button2.setEnabled(True)
        

        # 停止进度条
        self.progress_timer.stop()
        self.progress_bar.setRange(0, 1)
        self.progress_bar.setValue(0)
        self.scrolledtext1.clear()

        # 滚动到最后一行，这部分即是点睛之笔。
        self.scrolledtext1.setFocus()
        cursor = self.scrolledtext1.textCursor()
        cursor.movePosition(cursor.End)
        self.scrolledtext1.setTextCursor(cursor)
        self.scrolledtext1.append(result)   # 追加文本内容是在移动游标之后。
        if not success:
            self.scrolledtext1.append(f"操作失败: {result}")
