Delete item from QMap<int, QString> with shift

[Usernаme]

For example I want that after map.remove element with index 2 replace your index to 1..


#include <QApplication>
#include <QMap>
#include <QDebug>

int main(int argc, char **argv)
{
QApplication app(argc, argv);

QMap<int, QString> map;
map.insert(1, "some1");
map.insert(2, "some2");
map.insert(3, "some3");

map.remove(1);

qDebug() << map.value(1);

return app.exec();
};

You you please explain this a little bit better?

Do you want to remove the item at index 2? The item at index 2 is the item with key = "3" and value = "some3".
And do you want the item at index 2 to be replaced by the item at index 1?
