571182 - How to get widget corresponding to combobox dropdown

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Srini]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.70 Safari/533.4
Build Identifier: Firefox 3.6

I have a window handle for the combobox dropdown and I need to get widget corresponding to the dropdown. 

We do this by following code piece.
window  = GetPropA((HWND) windowHandle, (LPCSTR)sPropName) ; 
where sPropname is the "MozillansIWidgetPtr+pid" (pid is process id of firefox).
The above returns "nsISupports" value, which we convert to nsiwidget using
widget = do_QueryInterface(window) ;
 
Above piece of line goes bad, it returns null.

This was working fine in Firefox 3.5 but not on Firefox 3.6.


Reproducible: Always
