QGIS seems to have an integrated animation which purpose is to tell the user "Please wait, I am not freezing, I am processing"
What is especially cool about it is that it is perfectly integrated to QGIS GUI (docked in the bottom) and doesn't fill itself like a QProgressBar : it just bounces from one side to another, giving no informations about the progression, just saying "Wait, I am processing".
I would like to know if it is possible to call this bar from a plugin.
I know of alternate options, which are displaying a QProgressBar (in my plugin gui or in a QMessageBar). I even found this post, which seemed to ask the same question I am asking but ended accepting "Display a standard QProgressBar in a QMessageBar" as an answer. And this isn't what I want.
I am not considering options on how to tell my user to wait. I would like to know if there is a way to call this specific bar.
