Eric,
sorry, you missunderstood my proposed solution.
I wanted to suggest to NOT put additional events into whatever queue Iup
uses behind the scenes.
Instead better maintain you own queue and process this before you complete
Iup's queue once using IupFlush.

Hi,
I've got little success to get IupText with wordrwap=yes (and
mutliline=yes) to work.
I want the multiline text to be large enough to hold all the text (i.e.,
no vertical scroll bar), but _not_ expand=yes so it's not using more
space than required.
I'e got this working with expand=no and a m
I just tripple-checked my code, it never tries to change the border
after mapping. Only right after creation. Even before requesting
multiline=yes - which works. (Debian, gtk2)
So the problem must be something else. But how to nail it?

But it's nowhere near perfection. I can feel the app being slowed down
