关键摘要:

• 在keySequencesToNativeString函数中，使用std::copy_if和std::transform可能会导致不必要的性能开销，因为这些函数在C++11中已经被优化。建议直接遍历sequences并使用lambda函数来过滤和转换键序列。
• keySequencesToNativeString函数在actionmanager/command.h和plugins/option/optioncore/mainframe/shortcutsettingwidget.cpp中被重复定义，应该考虑合并到一个文件中。
• 在ShortcutSettingWidgetPrivate::checkConflict函数中，直接使用keySequencesToNativeString可能会导致不必要的函数调用和内存分配。建议在检查冲突时直接使用QKeySequence的toString方法。
• ShortcutSettingWidgetPrivate::updateShortcut函数中的keyStrList变量应该声明为const auto &，以避免不必要的拷贝。
