They don't enqueue events to the GUI event queue itself (at least
on the GUIs I am aware of). See my detailed response to John about
Android and look at the link I posted earlier.

Non-GUI threads on Android have no direct access to the GUI and they
have to communicate with the GUI thread via some form of generic
messaging and let code running within the GUI thread perform the GUI
operations on their behalf.
