virtual FPopupMethodReply OnQueryPopupMethod() const

Remarks

Popups can manifest in a NEW OS WINDOW or via an OVERLAY in an existing window. This can be set explicitly on SMenuAnchor, or can be determined by a scoping widget. A scoping widget can reply to OnQueryPopupMethod() to drive all its descendants' poup methods.

e.g. Fullscreen games cannot summon a new window, so game SViewports will reply with EPopupMethod::UserCurrentWindow. This makes all the menu anchors within them use the current window.
