解决Qt设置QTextEdit行高的问题_C 语言

QTextDocument* doc = ui->edtCountryIntroduce->document();    for(QTextBlock it = doc->begin(); it != doc->end(); it = it.next())  {      QTextCursor textCursor(it);      QTextBlockFormat textBlockFormat = it.blockFormat();      //set line height      textBlockFormat.setLineHeight(24,QTextBlockFormat::FixedHeight);        textCursor.setBlockFormat(textBlockFormat);      ui->edtCountryIntroduce->setTextCursor(textCursor);  }

    QTextCursor textCursor = ui->textEdit->textCursor();      QTextBlockFormat textBlockFormat;      //set line height      textBlockFormat.setLineHeight(24,QTextBlockFormat::FixedHeight);        textCursor.setBlockFormat(textBlockFormat);      ui->textEdit->setTextCursor(textCursor);
