关键摘要:

• 在updateEditorGeometry函数中，使用auto关键字可能会导致代码可读性降低，建议使用明确的类型名。
• fileview变量在声明后没有立即使用，可能是无用的代码，应该移除。
• 在if条件判断中，fileview->size().height() > viewHelper->viewContentSize().height()这个条件可能会导致逻辑错误，因为viewContentSize可能不是fileview的全局尺寸，而size方法返回的是窗口大小。
• setMaxHeight函数的参数使用了qMax函数，但没有检查maxHeight是否为负数，可能会导致setMaxHeight函数抛出异常。
• sizeHint函数的使用可能会导致性能问题，因为它需要计算一次布局。如果这个函数调用不是很频繁，可以考虑使用minimumSize代替。

是否建议立即修改:
是
