hi, LOR.
что-то тут не так. есть идеи?
$ls
wtf.cpp wtf.h
$cat wtf.h
#include <QSettings>
class C : public QSettings
{
Q_OBJECT
public:
C():QSettings("1","2"){}
int value(int key, int def) {
return value(QString::number(key), QVariant(def)).toInt();
}
};
$cat wtf.cpp
#include "wtf.h"
int main()
{
QSettings s("1","2");
s.value("3","123");
C c;
c.value(3,123);
c.value(QString::number(3),QVariant(123));
return 0;
}
$qmake-qt4 -project

int value(int key, int def) {
return QSettings::value(QString::number(key), QVariant(def)).toInt();
}
