Yes it's a limitation but I think most of the QT apps have these bugs 
all present. Back in the days when I was trying to script a QT based app 
so it might work better with NVDA on Windows I have created a hack which 
enabled reporting of individual cells while navigating in the tables and 
later on we have discovered it's okay to move that into a toolkit module 
rather than app specific one.

Okay I have came over preferences of VLC and mixxx my favourite QT4 
apps. I am quite surprised because I have found almost no more regressions.
Unfortunatelly comboboxes still don't speak their value change however I 
think you dojn't want to hear this at this point because it's been 
working like that since I'm using linux including orca 3.10. Also tab 
lists and the tabs inside are not announced corectly when focused e.g. 
the first tab is announced each time the tab control receives the focus. 
This tab lists issue is also present ever since I know QT accessibility. 
It's working like this on both linux and windows. Sliders, spin buttons, 
radio buttons, groupings and edit fields are working well.
What I have noticed that radio menu items such as audio devices in VLC 
don't anounce its state whether they are selected or not.

Later I will also try a QT5 based transmission QT to see how it works.

Greetings
