Small harmless warning: instance variable @callbacks not initialized about libui HOT 3 CLOSED

Hi @rubyFeedback

Thank you for your report.
I don't see this error in my environment.
So I don't know if this problem has been fixed, but I have replaced the code with one that does not seem to show the error.

Thank you

from libui.

I also saw the histogram.rb example

Thanks for looking at the histogram example.
But It is not my original. This example is ported from libui-ruby.
Writing Ruby code with garbage collection in mind is not a good experience.
There are many things that need to be improved.

Since Ruby/GTK has Cairo, I think it is easier to create this kind of code than LibUI.
Also, how to display images in LibUI is still not clear to me...
With Ruby/GTK, you can create something like this

If you want to display a chart in GUI, you can use GR.rb with GTK. See the following example.

from libui.

Released a new version that includes this change.
Thank you for your reporting!
