I made a bit of progress scripting Firefox 3, so am sharing it here in case someone can go further. This requires installation of the SayTools COM server attttt http://EmpowermentZone.com/saysetup.exe SayTools wraps a few Python modules, including one related to MSAA. It also includes a higher level convenience function I wrote called MSAAGetTree, which takes a window handle as a parameter and returns a string of MSAA properties in the client area of that window. Since SayTools can evaluate arbitrary Python code at runtime, other MSAA inquiries could be made via Python code passed as a string to the SayTools Eval method. I have not figured out how to get JAWS 9 to recognize keys in Firefox3.0.jkm, even though the script file it looks for is Firefox3.0.jsb. Has someone solved this one? For now, I inserted code in the AutoStart event (I copied the code in Firefox.jss for Firefox version 2 into the Firefox3.0.jss file that JAWS seems to associate with Firefox 3). Below is my AutoStartEvent function, followed by the text returned by the MSAAGetTree method of SayTools. Evidently, information about links and other properties of the page is present (I navigated to FreedomScientific.com). The information is incomplete, however, and at this point, I do not know why. Jamal void Function AutoStartEvent () Var Handle h, Object o, String s Let h = GetFocus() Let h = FindWindow(GetAppMainWindow(h), "MozillaContentWindowClass", "") ;MessageBox(IntToString(h)) Let o = CreateObject("Say.Tools") Let s = o.MSAAGetTree(h) CopyToClipboard(s) MessageBox(s) Let giMSAAMode = GetJCFOption (OPT_MSAA_MODE) EndFunction [Output of MSAAGetTree method] 1 RoleText: document Name:
