Re: [gtkmm] combining GTK with TAO

[aaron Lee <liwf nada kth se>]

Hi, Vlad,

Thanks you for your help. But I am not sure if I have got all of your 
idea to settle my situation.

1) I want to develop GUI both for Server and for Client. It means GUI 
not only send user's input to client through TAO, but it also need to 
receive data from client through TAO and display them as a response. How 
to realize?

2) If there is a mutex between GUI and TAO event loop. I mean if TAO is 
working to treat some task, GUI should not reponse use's input. Do you 
think it is possible?

3) Is there a way to send real-time data continuously  generated by 
scrollbar widget to a TAO client?

4)  I have  implemented TAO server/client in a thread. Is it possible to 
excute Gtkmm GUI in another thread and then communicate between these 
two threads?

Thanks,

Aaron
