To be more precise, following the original post in user mailing list, this file is to be able to enable or disable the frame visibility around thumbnails with a new option in Setup dialog.

Code used to draw frames around thumbnail is here:

https://github.com/KDE/digikam/blob/master/core/libs/widgets/mainview/thumbbardock.cpp#L238

Warning, there is another function used also to draw frames around thumbnail when items are grouped:

quick hack to disable iconview frames

This is a quick hack to see the effect of disabling frames around thumbnail. I just comment a portion of code in the first function listed in comment #2.

First icon is for grouped items, other one are single item. I think the rendering from non grouped items is the expected result. For grouped items, it need more adjustments, as grouped feature need to be more visible in icon view. Typically, if this kind of new option to change frame visibility is add in the future, this will only affect non grouped items.

Maik,

I would to know your viewpoint about this file. Typically, we can add a new option, enable by default, or do not change code and close this entry as well.

Best

Maik,

Do you read my last comment ?

If you are agree to add this option, i will do it next week.

Yes, of course we can make it configurable. I looked at various image management programs in Google Image Search. Most don't seem to draw a frame, not even a black line. Some make the thumbnails appear highlighted.
