## Detailed Description

The QGDict class is an internal class for implementing QDict template classes.

QGDict is a strictly internal class that acts as a base class for the collection classes QDict and QIntDict.

QGDict has some virtual functions that can be reimplemented to customize the subclasses.

- read() reads a collection/dictionary item from a QDataStream.
- write() writes a collection/dictionary item to a QDataStream.

Normally, you do not have to reimplement any of these functions.

## Member Function Documentation

### QDataStream& QGDict::read ( QDataStream & s, QCollection::Item & item ) `[virtual protected]`

Reads a collection/dictionary item from the stream s and returns a reference to the stream.

The default implementation sets item to 0.

See also write().

### QDataStream& QGDict::write ( QDataStream & s, QCollection::Item ) const `[virtual protected]`

Writes a collection/dictionary item to the stream s and returns a reference to the stream.

See also read().

For internal use only.

### QGDict::QGDict ( uint len, KeyType kt, bool caseSensitive, bool copyKeys ) `[protected]`

For internal use only.

For internal use only.
