I made some GUI-object, need to add some free-up method:

Method Free()
End Method

I figure I can kill the created gadgets easily with:

Method Free()
canvas=null
button=null
gccollect()
End Method

However, how do I get rid of the eventhook for this object? The manual is as zero'ish as it is ever:

Function RemoveHook( id,func:Object( id,data:Object,context:Object ) )

I figure 'id' could be 'self' ? And what is that func stuff/how to use it?
