Analog to ⎕wgive?
Is there a way for a running function to allow GUI objects to refresh themselves, like ⎕wgive did in APL*PLUS? Ctrl-Break seems to be the only way.
Re: Analog to ⎕wgive?
imo ctrl/break and wigive do not have the same effect.
quadDL should be an equivalent or the 'Yield' property of the Root object.

Agreed, the effect is not the same, except both show the Forms.
⎕dl 0 worked like a charm! Thanks for revealing that undocumented feature!

Glad that it helped.
But, with due respect, quadDL is actually documented.
If you have a very CPU intensive Dyalog application, which would delay the refresh of other (non-APL-generatd GUI) objects, you might want to consider running a separate worker thread and make it pause intermittently?

Documentation on ⎕DL:
> Y must be a simple non-negative single numeric value (of any rank). A pause of
approximately Y seconds is caused.
> The shy result R is a scalar numeric value indicating the length of the pause in
seconds.
> The pause may be interrupted by a strong interrupt.
...not sure where the flushing of the Windows Event Queue is mentioned.

For flushing the display buffer you'd have niladic Method 135 on the Root object,
besides the before mentioned 'Yield' property.
If you would use quadDL or a property/method of an enqueued GUI object (or Root) depends on the context.
