the frame of PyQt + Socket?

Hi,
 I want to write a PyQt4 program, which like a graph-ssh. One side
user choose server moder, and other side(s) user choose client mode.
Both of them have a GUI, they can connect via socket.

 I have study PyQt4 for a while and learn a little socket(from W.R
Stevens Unix Networking Programming). But I donot know how to integer
both of them.

 What the frame of this kind of program looked like? Or is there some example?

Thank you !!

ANN: new eric4 snapshot available

Hi,

I'd like to inform you about the availability of a new eric4 snapshot. It 
fixes a few bugs and contains this new/changed functionality.

- added a dialog to derive code for a forms implementation for Qt4
- changed the shortcuts dialog to show icons of the actions
- moved the dialog showing external tools used by eric4 to the
  preferences menu
- changed the handling of the commit message dialogs to enhance
  their usability
- enhanced win32 comptibility

As usual it is availabla via http://www.die-offenbachs.de/detlev/snapshots4/.

Regards,
Detlev

New Releases of PyQt4, PyQt3, SIP

I plan to make new releases of PyQt4, PyQt3 and SIP (probably) over the 
weekend.

Let me know if there is something that isn't fixed in current snapshots but 
should be.
