python - 将 QTextEdit 添加到 QScrollArea

Question

我的 QTextEdit 区域中有一个文本 block ，但它对于该区域来说太大了。我尝试将 textArea 添加到 QScrollArea 以使我能够滚动浏览文本。我想知道我哪里出了问题，因为它似乎没有做任何事情。我想知道什么是正确的做法。这是我的代码和输出的堆栈跟踪。

self.textEdit.setVerticalScrollBar(self.textEdit)
TypeError: QAbstractScrollArea.setVerticalScrollBar(QScrollBar): argument 1 has unexpected type 'QTextEdit'

Answer 1

QTextEdit 已经有一个 QScrollBar 所以你不应该添加任何，如果你想要文本不可编辑你应该使用 setReadOnly(True) 而不是 setEnabled(False)。

# passwordTF
self.textEdit = QtWidgets.QTextEdit(self.centralwidget)
[...]
self.textEdit.setFont(font)
self.textEdit.setReadOnly(True)
