XPGetWidgetUnderlyingWindow

WIDGET_API XPLMWindowID XPGetWidgetUnderlyingWindow(
                         XPWidgetID           inWidget);

Returns the window (from the XPLMDisplay API) that backs your widget window. If you have opted in to modern windows, via a call to XPLMEnableFeature(“XPLM_USE_NATIVE_WIDGET_WINDOWS”, 1), you can use the returned window ID for display APIs like XPLMSetWindowPositioningMode(), allowing you to pop the widget window out into a real OS window, or move it into VR.
