如何在字符右侧的QString中查找元素(How to find elements in a QString to the right of a character)

如何在字符右侧的QString中查找元素(How to find elements in a QString to the right of a character)

我有一个文件名作为QString，它看起来像“c：/ ..... /whatIAmActuallyInterestedIn.stuff”

我想在最后/之后获得所有信息，在这种情况下，这将是whatIAmActuallyInterestedIn.stuff

现在，我知道我可以将它转换为std :: string，使用rfind查找字符串中的最后一个/，然后将其转换回QString进行输出。 但是，这看起来像是为了我相当确定的QString内置的东西做了大量的工作，我找不到函数调用。

I have a filename as a QString which looks like "c:/ ..... /whatIAmActuallyInterestedIn.stuff"

I want to get all the information after the last /, which in this case would be whatIAmActuallyInterestedIn.stuff

Right now, I know that I can convert this to a std::string, use rfind to find the last / in the string, and then convert it back to a QString for then outputting. However, this seems like doing an excessive amount of work for something that I am fairly certain QString has built in, I just can't find the function call.

最满意答案

您可以像这样提取文件名：

QFileInfo("c:/ ..... /whatIAmActuallyInterestedIn.stuff").fileName();

You can extract the file name like this:

QFileInfo("c:/ ..... /whatIAmActuallyInterestedIn.stuff").fileName();
