c++ - Access QVector element index by its content -

i have qvector of qstrings , want remove element content, don't know how find index of it. know how can remove it? don't want iterate on , compare content value.

my qvector declared follows:

qvector <qstring> user_valid; 

and want remove content, example element value "marigold":

user_valid.remove(user_valid.find("marigold"); 

thank in advance!

ok, following if you:

• use qstringlist instead of qvector<qstring> has convenience methods can useful you; more common , hence comprehensive. spare 1 method call in case.

• just use removeone() and/or removeall() methods depending on exact scenario.

therefore, writing this:

qstringlist user_valid; user_valid << "marigold" << "cloud" << "sun" << "rain"; user_valid.removeone("marigold"); // user_valid: ["cloud", ,"sun", "rain"] 

if insist on using qvector<qstring> - bad idea in opinion -, need index first indexof() method, writing this:

user_valid.remove(user_valid.indexof("marigold"));
