Managing Event Queues
Overview
OpenROAD uses event queues to manage the order in which events are processed. Event queues can apply to the entire application or to individual frames. This chapter discusses:
• Event queues in the context of event-based programming and the three basic event types:
– Frame
– Field
– Menu
• Interrupting event queues that are programmed in event blocks
• Obtaining information about a current event
For a discussion of writing event blocks, see
Programming Frames.
