2005/03/03 14:17:28 thb 1.2.6.3: #i43927# Slightly changed the way updateScreen() is handled: since just lately, there were several places introduced which had to call View::updateScreen() manually (RehearsetimtinActivity, WaitSymbol, etc.). Together with the recent change regarding #i42499#, this resulted in the unfortunate situation that LayerManager::update() was not called before updateScreen(). Now, the view update is centrally handled by the EventMultiplexer (which also knows the LayerManager), I've therefore changed all direct calls to View::updateScreen() to EventMultiplexer::updateScreenContent() 2005/02/02 22:47:01 dbo 1.2.6.2: #i37777# - timing changes for activities queue - minor fixes Issue number: Submitted by: Reviewed by: 2005/01/30 16:00:59 dbo 1.2.6.1: #i37777# - using single presentation time base - activities queue detects and sets timing lag (calcTimeLag()) Issue number: Submitted by: Reviewed by:
