Hi,
I was able to reproduce your problem here.
If I try to run it from inside IupLuaScripter, it won't work either.
Except if I click on the IupLuaScripter window which is a window of the
same application with decoration.
Sometimes it does work and the focus is nil. But most of the time it does
not.
GetFocus returns the last element that had the focus in IUP, it is not a
system call. The element that had the focus must be notified of a killfocus
in order to GetFocus returns NULL.
It seems that elements in the dialog with this configuration are not
being notified of a killfocus. I tried to debug but WM_KILLFOCUS is not
even sent.
Sorry this seems to be a system behavior because the window does not have
decorations.
Best,
Scuri
