[nvda] Re: Some random thoughts

Could there not be some way of getting NVDA to recognize a parent window by tracing back from the first object in the nav tree? Even that though seems like NVDA would have to keep a register of all of the applications that are open at any given time and what object is in focus. I think maybe as I wrote in a previous post if NVDA could say when a main app window comes in focus instead of pane, it may clear up the confusion. But if I understand you correctly the trick is to be able to distinguish between a main app window and other window objects. ----- Original Message ----- From: "James Teh" <jamie@xxxxxxxxxxx>

We need to distinguish between unknown controls and a pane indication. In general, an unknown control has no relation to whether you switch panes. I have no objection to NVDA saying something like unknown control when it sees 
one it doesn't recognize.
Actually, the problem here is partially an NVDA issue and partially a Windows/MSAA issue. Whenever NVDA sees a window with an MSAA role of "client", it gets remapped to pane. The problem is that MSAA doesn't distinguish between application windows and other windows. The unknown control in the ExpressTalk application is not in fact a "pane" at all; it is a control with an unknown role. Mick and i were discussing some ways to make this a little nicer, but it's difficult when we're limited by the accessibility APIs we use.
