From 26eda933379801ef1c8b4b09e67d14f498cd3813 Mon Sep 17 00:00:00 2001 From: Chris Larson Date: Tue, 28 Sep 2010 08:24:55 -0700 Subject: Queue up events before the UI is spawned - Queue up any events fired to the UI before the UI exists - At exit, check if UIs exist, and if not, flush the queue of LogRecords to the console directly. - When establishing a connection from the UI to the server, flush the queue of events to the queue in the server connection, so the UI will receive them when it begins its event loop.
