WvQtStreamClone Class Reference

#include <wvqtstreamclone.h>

Inheritance diagram for WvQtStreamClone:

WvStreamClone WvStream WvErrorBase IObject

List of all members.


Detailed Description

Wraps another WvStream and attaches it to the normal Qt event loop.

If you are using this object exclusively to manage all of your streams, then you do not need to have a normal WvStreams select()/callback() loop in your application at all.

However, should you leave the Qt event loop and wish to continue using this WvStream, call qt_detach() first, then run a normal WvStreams event loop. If you do not do this, events may be lost! Later, you may resume the Qt event loop at any time by leaving your WvStreams event loop and calling qt_attach().

Multiple instances of this object may coexist to wrap different WvStream's or WvStreamList's.
