Re: [MACTCL] Widget greying and toplevel focus

[Steve A <ste...@gm...>]

Hmmm - I tried briefly to embed a container frame into the standard
ttk notebook demo, but i cant reproduce the issue :(

Attached is a screenshot showing symptom. Note - the disabled buttons
in two of the toplevels become active after we open another (true)
toplevel for a moment and close it.

I think i'll just need a workaround/hack to disable this "State is
greyed/disabled if no focus" feature of OS X wish. (What wer're doing
is complex, and has differing issues across all operating systems.)

I try binding  ButtonPress-1 to "focus .toplevel" or "wm state
.toplevel normal",
but the first does nothing, and the latter fails with the message
"can't change state of .toplevel: it is an embedded window". Note,
this error throw is unique to OS X. MSWindows and Linux don't complain
trying to change the state of these embedded toplevels.

Anyway, I'll keep looking for a working hack. Just curious if anyone
has messed with this before.

cheers.
