可以通过以下两种方法获取QTextLine中的内容:
1. 使用text()函数获取整个QTextLine中的文本:
```cpp
QTextLine line = textEdit->document()->findBlockByLineNumber(lineNumber).layout()->lineAt(linePosition);
QString lineText = line.text();
```
2. 使用textLength()和textStart()函数分别获取文本长度和起始位置,并使用QString::mid()函数获取QTextLine中的内容:
```cpp
QTextLine line = textEdit->document()->findBlockByLineNumber(lineNumber).layout()->lineAt(linePosition);
int textStart = line.textStart();
int textLen = line.textLength();
QString lineText = textEdit->document()->text().mid(textStart, textLen);
```
以上两种方法均可以获取QTextLine中的内容,具体使用哪种方法取决于实际需要。
