465446 - nsChildView::SetFocus doesn't focus when behind native Mac apps

Status: NEW

(Core :: Widget: Cocoa, defect)

Description

[David Humphrey (:humph)]

Spin-off from bug 459485.  Calling nsIDOMWindowInternal::Focus, and eventually nsChildView::SetFocus, can't get a Moz app (Thunderbird in this case) to come in front of a native Mac app.  I've used a work-around, but it would be nice to fix it at the source:

nsresult FocusAppNative()
{
  ProcessSerialNumber psn;

  if (::GetCurrentProcess(&psn) != 0)
   return NS_ERROR_FAILURE;

  if (::SetFrontProcess(&psn) != 0)
   return NS_ERROR_FAILURE;

  return NS_OK;
}
