Vision: Get Vision Display Events without Polling

[Andrey_Dmitriev]

Problem statement:

Right now the only way to get events from Vision Display (and from IMAQ Window) is polling. We should call method Get Last Event for Vision Display (or call SubVI IMAQ WindLastEvent for IMAQ Window) periodically:

As result some events may skipped and in additional, I don't like to have polling loop in my application.

Suggestion 1:

Add another Method "Wait for Event" with Timeout:

Suggestion 2:

Route events from Vision Display to the standard event structure, something like that:

I understand the suggestion, but its justification is somewhat misleading. You can detect mouse events in an Image object and from there do the necessary filtering using Get Last Event:

The existing mechanism is really counter intuitive. Have a virtual kudos.
