How to read and insert key and Value in the 3D QMap

[saad_saadi]

I am new Map in QT and have a 3D map like this

QMap<const char*, const char*> submap;
QMap<int, submap> map3D;

QMap<const char*, const char*> submap;
QMap<int, submap> map3D;

To copy to clipboard, switch view to plain text mode 

Now i inserted valued in it like this, the max of value of int is 5 but for each int value there is 50 key and value for submap.

1) How can i insert value in map3D. I am doing like this

submapD.insert(TempA,TempB);
map3D.insert(count,submap);

submapD.insert(TempA,TempB);
map3D.insert(count,submap);

To copy to clipboard, switch view to plain text mode 

count value will be incremented after TempA and TempB values will be more than 50 values.

Can anyone tell how i can read it back from map3D?

Thanks

If you mean access by key, just chain two calls of QMap::value()

const char *value = map3D.value(someInt).value(someCharStar);

const char *value = map3D.value(someInt).value(someCharStar);

To copy to clipboard, switch view to plain text mode 

Btw, since you use a low level type (const char*) make sure the pointers stay valid during the life time of the map
