RolloutCreator - Get Rollout Class

Hi there, i know i have another thread pending, but i'm trying to make a quick script, using RolloutCreator for the first time.

I have to create X copies of a rollout and add them into a rolloutfloater, i just need one parameters (a number) to difference them, this parts seems to work, but i can't manage to create a rollout outside my function.

2nd Problem (minor): i cant' add the tooltip parameter when creating the button.. but it work well to assign a string when the rollout open.

3rd Problem: to assign tooltip or make events, i have to imput the right name and not the var wich contain the string name of the button (it result a string and not a button class) i wanted to avoid the execute function.

Here is the code:

fn createrolls thenumber thevar =
(
therollname = "roll" + thenumber as string
therollcaption = "Copy/Paste" + thenumber as string
button1name = "Copyselected" + thenumber as string
button1caption = "Copy" + thenumber as string
	
thevar = rolloutCreator therollname therollcaption
thevar.begin()
thevar.addControl #button button1name button1caption filter:on paramStr:"width:100 height:20"
thevar.addHandler therollname #open filter:on codeStr:" \n print thenumber as string"
thevar.end()
)

createrolls 2 toto
--createDialog toto

-- Copyselected2.tooltip = @test@

I wanted to hold the rollout into the var toto, but it's seems to be a dirty way of doing it.

thank's in advance for your help, this forum is the only source i have when i'm lost. I've been looking on the web for 2 days, but i can't find a good response.
