How to add Blinking Text in Qlikview Applications

Qlikview Maven has a nice little post on how to create blinking text boxes or blinking backgrounds to text in Qlikview applications. Use sparingly! But these really could come in handy for alerts, say medical monitoring of patients or monitoring servers or something similar. Best for real or near-real-time applications perhaps.

Occasionally, I’m asked if QlikView supports blinking text. Here’s a method that you can use if it is necessary. I don’t recommend this technique unless you have some kind of seldom used message that the document user absolutely must see (like “This data is invalid” or “Warning. Your chair is on fire!”) In any case, it is easy to try it out and see what thalert-icon-red-mde effect looks like.

Text in a text expression can be made to blink between two alternate forms with something like this:
=if(Odd(Second(Now(1))), ‘*** Hey, Look ***’, ‘/// *** \\\’)

Something more effective at attracting attention is to blink the background color of a text box.  Your text box should show constant text or a text expression that does not use the Now() function.

He reminds us to watch out for the Now() function, because it can eat up server resources if used too much.
