NI LabVIEW 2013

Description

LabVIEW 2013 includes the following enhancements to event-driven programming and related functionality. Viewing Enqueued Events at Run Time In LabVIEW 2013, you can inspect the events waiting in an event queue associated with an Event structure. You also can view a list of VIs that contain Event structures with registered events and a log of the events the Event structure handled. Right-click an Event structure and select Event Inspector Window to view the event information. Customizing When a Control Responds to Movements of the Mouse Wheel In LabVIEW 2013, you can specify when a control responds to mouse wheel movements. To do this, navigate to the Key Navigation page of the Properties dialog box for that control. Then select from the available options for the Built-In Mouse Wheel Support component. For example, you can select whether a control responds to mouse wheel movements On Hover or On Key Focus. [Idea submitted by NI Discussion Forums members tst and jacemdom1] Enhancements to the Edit Events Dialog Box The Edit Events dialog box includes a checkbox that allows you to specify a maximum number of event instances to keep in an event queue. If you enable Limit maximum instances of this event in event queues, LabVIEW maintains the queue limit by automatically discarding older events from the event queue as newer events of the same event type arrive. New and Changed Events Functions LabVIEW 2013 includes the following new and changed functions: The Events palette includes a new Flush Event Queue function. You can use this function to discard the least recent notify events from one or more event queues. The Generate User Event function includes a priority input that allows you to specify normal priority or high priority for the user event. When you specify high priority, LabVIEW enqueues the user event and associated event data into the event queue in front of any previously generated normal priority events. Programmatically Controlling Event Structures LabVIEW 2013 includes new VI Scripting properties and methods to control Event structures. Block Diagram Enhancements LabVIEW 2013 includes the following enhancements to the block diagram and related functionality.
