[Qt-interest] Only one instance of designer.

[Surya Kiran Gullapalli]

Hello all,
When I open any ui file in designer, I want to open the ui file in an
already running instance of designer (from python code)

I've looked at designer source code, and found the -server and -client
command line options. I tried something like this.

first start server

designer -server &

this will give me the port to connect to and start client with the port
number.

designer -client <portnum> &

After this, I'm seeing two designer instances running. How can I enforce
only one designer ?

Thanks in advance,
Surya
