problem in QString

[wagmare]

hi friends,



const char *str;
QString path;
path = lineEdit->text();
str = (const char *)path.latin1();
// str = (const char *)path.local8Bit());


but compilation gives error: ‘class QString’ has no member named ‘latin1’
or local8Bit() why its showing like this....
please help ..

well, it is showing that because...
a) you are using Qt4 and that is simply the truth: there is no such method (there is QString::toLatin1(), though)
b) you are using Qt3 and forgot to #include <QString>

HTH

QString::latin1() is Qt 3. In Qt 4 it's named a little bit different. Make sure to read the correct version of docs.

first thanks for reply guru :)

you are right i am using Qt4.4.3 .... i just follow one good example in net without considering
version .....

Just notice that the example you've found is a bit problematic. QString::toLatin1() returns a QByteArray object. You store a pointer to the internal data of that temporary object. "const char* str" is a dangling pointer as soon as the QByteArray object goes out of scope. For more details, see TT knowledgebase: How can I convert a QString to char* and vice versa ?
