Using STL in Qt4 vs. Qt3

[hvw59601]

Hi,

This shows my ignorance, but in Qt3 I could do:

//      Find the latest mtime...
for (vector<string>::const_iterator iss = new_partitions->begin(); iss != new_partitions->end(); ++iss) {
        QString this_string = (*iss);

//      Find the latest mtime...
for (vector<string>::const_iterator iss = new_partitions->begin(); iss != new_partitions->end(); ++iss) {
        QString this_string = (*iss);

To copy to clipboard, switch view to plain text mode 

to which I get an error:

do_test_gpc.cpp:323: error: conversion from 'const std::basic_string<char, std::char_traits<char>, std::allocato
r<char> >' to non-scalar type 'QString' requested

do_test_gpc.cpp:323: error: conversion from 'const std::basic_string<char, std::char_traits<char>, std::allocato
r<char> >' to non-scalar type 'QString' requested

To copy to clipboard, switch view to plain text mode 

Could someone point out what should be done instead?
Thanks!

In Qt 4 you have QString::fromStdString().

In Qt4 implicit convertion from std::string to QString is no longer supported.
You need to make use of QString QString::fromStdString ( const std::string & str )

Instead of :

...
        QString this_string = (*iss); 
...

...
        QString this_string = (*iss); 
...

To copy to clipboard, switch view to plain text mode 

You need to write:

...
        QString this_string = QString::fromStdString(*iss); 
...

...
        QString this_string = QString::fromStdString(*iss); 
...
