I fear your program is poorly designed, that kind of thing
shouldn't be necessary.
But it is possible by using the EventLoop struct directly.
http://dpldocs.info/experimental-docs/arsd.simpledisplay.EventLoop.html
EventLoop.get.exit() will exit the loop, though it may not want
to start up again (I have never tried).
You can also do something like, after setting it all up,
bool done;
EventLoop el = EventLoop.get;
el.run(() { return !done; });
And that delegate you pass to `run` tells it when to return.

I will submit a pull request on your GitHub page. Cheers.

I have sent you an e-mail on your destructiona...@gmail.com account. I would prefer to talk there rather than here. I would just like to understand what is causing the problem so I can figure out a bypass.

Thank you so but so much. I tested it here and it works.

I realize that line is a bit silly looking, it loads a file,
converts it to a displayable format, then pops up a window to
display it. Any key pressed in the window will close it.
You might need something more complex, and the lib can do it. You
might also want something less complex (that `arsd.image`
actually loads 7 different modules for various image formats),
but it isn't super hard to use anyway:
Download the code here:
https://github.com/adamdruppe/arsd
You can put all those files in an `arsd` folder next to your
program, and `dmd -i yourfile.d` to compile it all at once.
Or if you want to load the files yourself, you can list them all.
If you just need png and/or jpeg specifically, you can jus get
jpeg.d and/or png.d, together with simpledisplay.d and color.d
from the repo and call these functions:
http://dpldocs.info/experimental-docs/arsd.jpeg.readJpeg.html
http://dpldocs.info/experimental-docs/arsd.png.readPng.html
So the code looks like:
---
import arsd.simpledisplay;
import arsd.png;
void main() {
displayImage(Image.fromMemoryImage(loadPng("filename here")));
}
---
or of course changing png to jpeg if you want that. (You can put
that on an if based on the image filename - that's what the
arsd.image library actually does).
Then compile:
dmd yourfile.d color.d simpledisplay.d png.d jpeg.d
But the first option with dmd -i is prolly the easiest.
If you need mroe control over the window, let me know, I will
type that up too.
also take a look at the docs
http://dpldocs.info/experimental-docs/arsd.simpledisplay.html
BTW I didn't mention this in your other thread because PlaySound
is easier to use anyway, but I also have an audio module:
http://dpldocs.info/experimental-docs/arsd.simpleaudio.html I'm
just not 100% happy with it so I don't talk about it much.
