[ace-users] [EXTERNAL] [TAO+Qt5] How to code a Qt5 application with CORBA objects

[Johnny Willemsen]

Hi,

> I have an app using Qt 4, you should use the QtReactor.
> Internally it will call the Qt Eventloop.  
> 
> Qt with TAO should be a single threaded app.

> There is a performance hit in how Qt event loop is called (we changed
> it) but works perfectly fine as is.

We welcome user improvements to ACE/TAO, only review capabilities are
very tight at this moment. Maybe you can open a PR with your QtReactor
enhancements, see https://github.com/DOCGroup/ACE_TAO.

Best regards,

Johnny Willemsen
