Hi,
Yes, unfortunately we still don't have an official tutorial. But inside
the documentation you can find a tutorial for IupLua which can help you
understand the concepts.
Regarding IupCanvas, the process is the same. There are several callbacks
you can use to handle mouse input. You just have to store the information
you need afterwards.
Best,
Scuri
