Note that you can still know the size of the file you are getting using
|
|
wxStreamBase::GetSize. However there is a
|
|
limitation: in HTTP protocol, the size is not always specified so sometimes
|
|
@c (size_t)-1 can returned ot indicate that the size is unknown. In such
|
|
case, you may want to use wxInputStream::LastRead
|
|
method in a loop to get the total size.
|
|
|
|
@returns Returns the initialized stream. You must delete it yourself once
|
|
you don't use it anymore and this must be done before
|
|
the wxHTTP object itself is destroyed. The destructor
|
|
closes the network connection. The next time you will
|
|
try to get a file the network connection will have to
|
|
be reestablished, but you don't have to take care of
|
|
this since wxHTTP reestablishes it automatically.
