custom property parameter OnChanged callbacks 2005-06-19 - By benp

thanks Aloys!
yeah, pretty annoying!
Thanks for the workaround suggestion.
I was actually using an enum control (siControlIconList) with only a
single icon to simulate a bitmapped button - really nice to look at!
The button then fired off a parameter plotting function. But because the
enum control is built on an underlying paramety, so instead of
OnClicked i use OnChanged and then set the enum control back to an
'unselected' value after the plotting to make the single icon list
behave like a button. But of course the OnChanged gets triggered in this
odd way, making it useless!
Oh well, at least i ended up learning something by the end of the saga.
It's annoying ending a session knowing less than when you started!
So, regular buttons for me ..
cheers
