So aside from get_accChild, there doesn't appear to be any reason for a child object to have an ID. If a child object has no ID, what use is get_accChild? If you rely only on MSDN, probably no use. However, MSDN only defines the interface; it is open to interpretation by the developer of each accessibility server.
Thank you for looking into this. Based on this, I feel that the
accChild method should not be encouraged as a standard way to access children.

Also, I wanted to be able to parse from the selected object back up the to window object & populate the structure back down to the selected object.
I think I finally accomplished this,
with sinkfaze's help. Here is an example:
Code:
ComObjError(false)
F1:: ; access the object under then mouse, then re-access it from the window object
PtObj := Acc_ObjectFromPoint(child)
child_path := GetAccPath(PtObj, hwnd)
WinObj := Acc_ObjectFromWindow(hwnd)
ChildObj := Acc_GetChild(WinObj, child_path)
MsgBox % "--Window + Path--`nName:`t" ChildObj.accName(child) "`nValue:`t" ChildObj.accValue(child) "`nLocation:`t" Acc_Location(ChildObj, child).pos
. "`n`n`n`n"
. "--From Point--`nName:`t" PtObj.accName(child) "`nValue:`t" PtObj.accValue(child) "`nLocation:`t" Acc_Location(PtObj, child).pos
return
Acc_GetChild(Acc, child_path) {
Loop Parse, child_path, csv
Acc := A_LoopField="P"? Acc_Parent(Acc):Acc_Children(Acc)[A_LoopField]
return Acc
}
GetAccPath(Acc, byref hwnd="") {
hwnd := Acc_WindowFromObject(Acc)
WinObj := Acc_ObjectFromWindow(hwnd)
while Acc_WindowFromObject(Parent:=Acc_Parent(WinObj)) = hwnd
t1.="P,", WinObj:=Parent
while Acc_WindowFromObject(Parent:=Acc_Parent(Acc)) = hwnd
t2:=GetEnumIndex(Acc) "," t2, Acc:=Parent
return SubStr(t1 t2,1,-1)
}
GetEnumIndex(Acc, ChildId=0) {
if Not ChildId {
ChildPos := Acc_Location(Acc).pos
For Each, child in Acc_Children(Acc_Parent(Acc))
if IsObject(child) and Acc_Location(child).pos=ChildPos
return A_Index
} else {
ChildPos := Acc_Location(Acc,ChildId).pos
For Each, child in Acc_Children(Acc)
if Not IsObject(child) and Acc_Location(Acc,child).pos=ChildPos
return A_Index
}
}
The data should be the same, even though one was accessed via
Acc_ObjectFromPoint & one via
Acc_ObjectFromWindow + a child path. An exception may be if the object under the mouse doesn't expose much IAccessible information - such as a Google Chrome Webpage. Besides these types of exceptions, I would like to know if anyone identifies any IAccessible object that the above script provides differentiating data for.
