The interface allows you to drop one image onto another in the Thumbbar when you are previewing images to group them. However, after you have done it this way, it disappears in digikam. If you right-click on the image, you do not get a "group" option in the list to ungroup them. The missing image is still viewable via the system file explorer, you just can't get to it in digikam anymore... Reproducible: Always Steps to Reproduce: 1. Enable thumbbar (Settings > Show thumbbar) 2. Open Preview (F3) 3. Drag one image on top of another to "group" 4. Try to ungroup...Impossible Actual Results: Image cannot be ungrouped. Expected Results: Should be able to ungroup image.
I can not reproduce the issue with digiKam 4.12.0. It is right, in the thumbar images can be grouped. The ungrouping is possible in the icon view. Maik
Maik, It's a question ? "It is right, in the thumbbar images can be grouped. The ungrouping is possible in the icon view." If we can group items from thumbbar but not ungroup it at the same place this can be problematic. I vote to disable grouping function for thumbbar for the moment. Gilles
It sounds like Maik does not find the problem. Maybe something has been fixed between my version (4.7.0) and his version 4.12.0? (I am using version in Kubuntu 15.04 so cannot test the latest.) If the problem is not occurring in 4.12.0, maybe the function does not need to be disabled?
Although, it is true--if we can group in thumbbar, ungroup also via thumbbar would be best. Sorry for double comment.
OK, for a new test now, I can actually see a problem. The grouping is performed not now under the picture that has been selected, but depending on the album some pictures in front or behind. I will check it. Maik
Created attachment 94288 [details] imagedragdrop.patch The thumbbar has an addition NoDuplicatesImageFilterModel. Thus, the index is no longer always syncron with the icon view. Depending on the album can the grouping work correctly using drag & drop, but need not be. The grouping will be executed under a different image in the album. This patch fixes the grouping in the thumbbar. Maik
tested and work fine here... Gilles
