RE: Support for flowsto/flowsfrom in IE11

Hi Stefan,

IE11 (and 10) supports flowsto and flowsfrom, but flowsfrom is a non-standard work-around we implemented because we don’t have secondary relationships in UIA. I’m not sure that it’s the way we want to handle this in the future.

Also, inspect supports UIA. There is a “UIA Mode” in the Options menu. If it’s not there, you may have a very old version of Inspect.  In general, you will want to use the “Control View” (also on the Options menu) when testing browser implementation.  You can also see the Text Pattern by placing focus on the document node, and choosing Text Pattern Explorer from the Action menu.

Hope that helps,
Cynthia

Hi Cynthia,

is this a known limitation for IE11? Since inspect goes straight MSAA, is flowsto/flowsfromsupported in UIA?

@Steve: many thanks for quick reply!

Best Regards
Stefan

actually there is also flowsfrom property
https://msdn.microsoft.com/en-us/library/windows/desktop/ee684017%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396

unclear whether either is supported. When interrogating flowto in
http://s.codepen.io/stevef/debug/PPXZWY using inspect.exe / IE11

FlowsTo:    [Not supported]
FlowsFrom:    [Not supported]
is returned

From the reference given one could have the impression only Firefox with IA2 supports flowto/flowfrom relationships.

you are correct, IE supports flowto via UIA flowsto property

doesn't look like the reverse relationsnhip (flowsfrom) is supported though.
