All: I have recently run into a situation for which there presently doesn't appear to be a good solution. 1. The problem. I wished to obtain the attributes for the text at a particular offset. This is straightforward using IAccessibleText and just asking for the attributes at the offset of interest. The difficulty is that the node whose text attributes I wanted didn't support IAccessibleText. One of its ancestors did and this ancestor did contain information about the attributes I needed. The question then became, how can I find out where in a given IAccessibleText string does a descendants node text begin. I haven't found an easy way to answer this question. 2. Proposed solution: Add a new function that returns the offset in the current IAccessibleText text string for a given IAccessible for a descendant. So something like: DescendantOffset(IAccessible* acc,VARIANT varChild, long* offset)
I have no strong preference for exactly how this should be handled, just the need for such a function. I know the 1.3 version of the IAccessible2 specification is nearly ready, but I would like to see if this new function could be included. In addition to the attributes for text at a given offset, I have also seen a case where we needed the rectangle for particular characters. Again, in this instance, we needed to locate the nearest ancestor supporting IAccessibleText and try to determine the offset in this ancestor of the node of interest. What does everyone think about such an addition? Any feedback would be much appreciated. Thanks, Brett Lewis
