Solved Changing QStringList with number to another QStringList
-
Hi,
I have a QStringList which has
winter1.jpg
winter2.jpg
winter3.jpg
...
winter999.jpg
I need to changed this to another QStringList which has
winter001.jpg
winter002.jpg
winter003.jpg
...
winter999.jpg
How can I change it in Qt? -
I'll go with a foreach and a regular expression.
Or with a lambda function and a std::transform. -
Really depends on how universal your transformation has to be.
In the case you describe, I would probably do something like this:
QString addZeros(QString s, int size = 3){ while(s.size() < size) s.insert(0,'0'); return s; } .... for(QString sEntry : myStringList){ QString replaceString; for(int i = 0; i< sEntry.size(); if(sEntry.at(i) >= QChar('0') && sEntry.at(i) <= QChar('9')) replaceString.append(sEntry.at(i)); } sEntry.replace(replaceString, addZeros(replaceString)); }
