Progress Bar with unknown state or showing animated gifs

Hi,

is there a way to have a progress bar with unknown state?

e.g. https://i.stack.imgur.com/gz9GK.gif

ProgressBarMorph / Job / SystemProgressMorph seem to be based around progress only.

Alternatively, is it possible to (easily) display animated gifs?

Thanks,

Peter

You can take a look at how I do seconds indicator in my ChronosManager tool, its just a simple ImageMorph stepping through png images with transparency.

Hmm, thanks. I can write it myself, that's not a problem.

I am just surprised that there is no native support/lib... I'll see if I can do something about it.

Re: Progress Bar with unknown state or showing animated gifs

well "native" in this case would mean OS library. Most likely there is and you can use the UFFI to do it but I assume here you mean Morphic.

I have played around with Progress bar when I was trying to increase its size for PharoLauncher. As almost all things inside Pharo is not documented and its entangled between messages. But yeah it should be possible to animate the green bar so it bounces left and right. If my memory serves me correctly its not nothing more than a set of super simple morphs tied to announcements.

Its that my mentality usually is if something is simple enough as an idea it does not worth wasting your time learning how a poor documented library works. I have wasted huge amounts of time trying to understand Pharo libraries and tools, so I learned the hard way.
