Do you see something like this (i.e. everything greyed out except for the cancel button)?
If closing the window is how this works, there should probably be a popup when opening RT (or any program used to import a raw to gimp) that says that you should close the window when finished. This is not at all intuitive: Closing a window feels like losing work not submitting it (that would be an “ok” button of some sorts).
Yes, does work although there was a delay. I ran Gimp from a terminal and I could see something was happening. eventually opened.
thanks once more.
Maybe obvious, but still:
Actually usually I am opposed to anything popping up and I think I am not alone with this. So there should be an option to not show it anymore.
yes, that was implied, but I should have stated it explicitly 
Care to elaborate?
Everyone has their own preferences, would be a boring world if everyone was the same.
Nice application but not for me. When I first tried Darktable, some time ago, my first impressions, I do not need another file manager, why does it need to be one.
To be fair to this thread which is Gimp and RT, I just tried Darktable as a plugin to open a RAW image. With the caveate that the DE is KDE I get this.
Denying the KDE wallet a few times (Why that? my regular machine has Wallet disabled) and closing the warning, it was 25 seconds to open/analyse the image to get to the state with the little icon imge at the bottom. All I want is that image into Gimp, taking the hint from RT I closed the window, waited 20 seconds and got the image into Gimp.
Less than a minute but subjectivly seemed much longer. You think, What has gone wrong? Why is it not opening? all the things when nothing happens.
What I really want is a Gimp plug-in that will just open the d… file. I have one but it does not work any more. Opens an image up almost imediately, set the output to 16 bit, 5 seconds into Gimp 2.9.5
Now there is the challenge to RT/Darktable - make one of those.
@agriggio The above sounds like another pop-up after closing RT is needed, saying something like: “RAW is being converted, the result will soon be displayed in Gimp.”, possibly with a progress bar 
so, why is this a challenge to RT/DT and not a bug report to the now broken plugin that you are happy with?
converting a RAW to a high quality image takes time. Both RT and DT try to be as fast as they can, but there’s no magic in there. If the speed is not acceptable for you, I think wou will have better luck with a solution that trades efficiency for quality.
Well, for a person who is opposed to pop-ups, you seem to really like them 
Look at it this way, Gimp 2.9.5 at the moment will only permit DT/RT to open a RAW image from the Gimp File → Open menu.
Which is fine if you want to use DT/RT I do not have any issues with DT/RT
I would prefer to use a much simpler interface, which if you look at earlier posts (no. 2) one is shown. The plugin still works, but not from the Gimp menu.
You are correct, I need to submit a bug report, but it needs to go to the Gimp maintainers not the plugin.
As far as I am concerned, I found out what I needed, how to get an image out of DT/RT and into Gimp. Close the window. No more discussion required.
Ok, all good then! 
I read most of the thread, but did not see a valid response while I just exercised this feature yesterday with rawtherapee-5.2.
By the way, “CTRL + e” is interpreted as “edit current image within external editor”, or my preferred lingo would be more simplistic “export image”!
Does it really say “The Gimp”? The image editing program is called GIMP, not “The Gimp”, so if it’s as you say then it needs fixing.
“Bring out The Gimp.” 
Here he is! 
Currently I have GIMP 2.9 set up to use darktable, PhotoFlow, and RawTherapee as possible raw processors.
AFAIK any raw processor can be used to open raw files directly from GIMP 2.9. But to make this happen, the raw processor developer does need to use the new GIMP code for connecting the raw processor to GIMP’s image import dialog: https://bugzilla.gnome.org/show_bug.cgi?id=786100 - note added: this is the wrong link, not sure how I managed to put a “C” after the “786100”, but @rich2005 very kindly posted the correct link below.
It is this one Bug 786100 – RAW plug-ins limited to Rawtherapee / Darktable I posted it and got knocked back.
Natterer said “Add that single line gimp_register_file_handler_raw() to the nufraw code”
Of course it is more complicated (at least to my eyes) than that.
Since I seem to be the only one here, who simply wants something that just opens a RAW file in Gimp, I took the easy way out and disabled the offending plug-in file-raw-placeholder until nufraw is updated.
Back to opening a RAW file in 2 or 3 seconds.
