pyqt中如何取消textbrowser控件的滚动条

你可以使用`QTextBrowser`的`setVerticalScrollBarPolicy()`方法来设置垂直滚动条的显示策略。如果你想要禁用垂直滚动条，可以将其显示策略设置为`Qt.ScrollBarAlwaysOff`。示例代码如下：

from PyQt5.QtWidgets import QApplication, QTextBrowser, QWidget, QVBoxLayout, QAbstractScrollArea
from PyQt5.QtCore import Qt
import sys

app = QApplication(sys.argv)

widget = QWidget()
layout = QVBoxLayout(widget)

text_browser = QTextBrowser()
text_browser.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOff)  # 禁用垂直滚动条

text = "This is a long text that requires scrolling to read. This is a long text that requires scrolling to read. This is a long text that requires scrolling to read."
text_browser.setText(text)

layout.addWidget(text_browser)
widget.show()

sys.exit(app.exec_())

在上面的代码中，我设置了`text_browser`的垂直滚动条显示策略为`Qt.ScrollBarAlwaysOff`，这样就可以禁用垂直滚动条了。如果你想要禁用水平滚动条，也可以使用`setHorizontalScrollBarPolicy()`方法来设置水平滚动条的显示策略。
