Detailed Description

Event based input handler.

Gets events from the Input system. Calculates current keyboard modifier state for later keyboard and mouse events. Applications calls UpdateState first for each rendering frame to get new input events. Then the new events are looped through using the events() method.

updateState()

void Cogs::Core::EventBasedInput::updateState	(	const Cogs::Keyboard &	keyboard,
