How "draw" method is executed from Stack in FlowStone/Ruby?

For the last time ever (I really need to catch this): I need to understand how Ruby stack "draw" method when I call it, because I don't get how it is executed with the logic I have now, and 90% of graphics I want to make fail due to this dubt I'm not able to get.
Pretty basic example:
Code: Select all
def setParameters
@watchs+="p1 "
end
def getCoordinates
@watchs+="c1 "
end
def draw i,v
watch "watcher_b", @watchs+"d1 "
end
def event i,v
if(i=="trigger1")
@watchs=""
@watchs+="e1 "
setParameters
getCoordinates
@watchs+="e2 "
redraw 0
@watchs+="e3 "
elsif(i=="trigger2")
@watchs+="e4 "
setParameters
redraw 0
@watchs+="e5 "
end
watch "watcher_a", @watchs
end
Open the schematic and trigger with the button. What I'd aspect from it, its that the output is:
e1 p1 c1 e2
d1 e3 e4 p1
d1 e5
Instead its:
e1 p1 c1 e2 e3 e4 p1 e5
without
any "redrawing" between methods called in event. Seems that it first processes all the "events" method inside Ruby event, than add "redraw" method to the stack, to be called at
some point (later?).
Well, this is the part I miss: what's this "some point"? Is it scheduled random? Is it "as soon as possible" following a Redraw ticks? (so if I'm lucky and the tick is between e2 and e3, I'll get a redraw?)
Can you help me to understand this?

Try this, this show some redraw strangness....

Ruby Redraw Stack_strangness.fsm
Yes, additional ones! But it doesn't reply to my question

The layer of execution is just as important. Where does the drawing happen on the hierarchy? Is a called method an instance method or a class method (everything you define is aninstance method, while, for example, redraw is a class method (read about it in the user guide, chapter 8)?
I've made a few simple changes that will help you understand the hierarchy of events better.

Hi dude, totally forgot about this topic! Now I've found the same problem, so it's time to reup and understand better this "ruby" hierarchy. I've looks at the Chapter 8, but I see nothing about instance/class method (which is a classic concept of object oriented programming).
Where is wrote that redraw is a class method (and it is executed after instance method)?

I meant to read in chapter 8 about 'redraw'. Chapter 8 explains how Flowstone integrates Ruby. If you want to know how Ruby (it's the only real OOP language to date
) itself works, which is what you try to understand, you have to google for interesting Ruby tutorials.

That's wrong, redraw is an instance method (Check it with self.methods and self.class.methods)
RubyEdit doesn't have any class methods.

Thanks for correcting that!

Uhm, I'm confused. So why redraw (thus draw method) is executed after the event method finished (and not at the point I invoke it)? Will ruby prevent many drawing settings a timeout?

because in fact it is handled by C ++ side,
and in any case it is taken in mind that all RubyEdit modules are operated in turn by a class not exposed to us
and are executed in a Fiber method execution.
