I have written a test GUI application to see how to update a R3-GUI from a network event.

The server port receives the event from a client, but using

set-face window-inputarea msg

fails to update the GUI unless I also mouse over or otherwise generate a GUI event. This then seems to kick off outstanding event handling.

Do I need to send a simulated GUI event to allow this to happen programatically or is there another way?

There's a bug in the area style so that set-face in this instance does not update the face.

I've updated the example to show it working.

  • Turns out that updating the GUI from a network event can trigger a #9910 network error, apparently due to a malformed event/port being somehow injected into the event queue. – Graham Chiu Jun 24 '13 at 04:53
  • The network event bug has been fixed in Rebol now but updating the GUI is still haphazard due to more GUI bugs. – Graham Chiu May 02 '14 at 04:12
