Network / SocketTCP::IsValid() not working?

« on: April 12, 2011, 03:49:21 am »

I get this backtrace:

Code: [Select]

Program received signal SIGPIPE, Broken pipe.
0x00007ffff6d37812 in __libc_send (fd=<value optimized out>, buf=0x6388b0, n=6, flags=<value optimized out>)

When I close my client.  When I try to send the next packet it crashes, even if I perform a SocketTCP::IsValid() check... it wasn't doing this earlier and I have no idea what I changed to make it not work...

Network / Max Packet Size?

« on: April 08, 2011, 09:56:34 am »

Is there a way we can block sending packets of certain sizes.  Since the sf::Packet uses a int32 size header, it can support packets upto 4gigs... but I don't want this to lead to abuse of my server's bandwidth and memory, and such.

Network / HTTP / FTP download status

I am using HTTP/FTP to get game updates, which can be quite large.  Is there a way to determine percentage done as it downloads?

Window / TextEntered vs. KeyPressed

« on: March 15, 2011, 02:28:25 am »

I have a text box, when players enter text it will display.   I am having issues though as it seems that one key pressed will generate TWO events.

How can I determine which event I should listen to, and when.

Secondly, how can I flag the other events so it can be ignored further down the widget tree.
