Created attachment 102451 [details] Krusader in Plasma 5 using Breeze icons, that's ok. Hi! When you use KDE Plasma 5 you can specify which icons you want to use (you can go to System Settings > Icons), when you use the Oxygen icons in Kubuntu 16.04: there is at least one icon in Krusader that is not correctly seen (for more detail: some screenshots are attached). Thanks for Krusader!

Information about the icons: In the source code of Krusader, in the viewactions.cpp file, we can see: actSelect = action(i18n("Select &Group..."), "edit-select", Qt::CTRL + Qt::Key_Plus, SLOT(markGroup()), "select group"); actSelectAll = action(i18n("&Select All"), "edit-select-all", Qt::ALT + Qt::Key_Plus, SLOT(markAll()), "select all"); [...] actUnselectAll = action(i18n("U&nselect All"), "edit-select-none", Qt::ALT + Qt::Key_Minus, SLOT(unmarkAll()), "unselect all"); and therefore we can see that each action has to have a related icon ("edit-select", "edit-select-all" and "edit-select-none"). It it's executed $ find / -iname "*edit-select.*" 2>/dev/null /usr/share/icons/breeze-dark/actions/22/edit-select.svg /usr/share/icons/breeze-dark/actions/16/edit-select.svg /usr/share/icons/breeze-dark/actions/24/edit-select.svg /usr/share/icons/breeze/actions/22/edit-select.svg /usr/share/icons/breeze/actions/16/edit-select.svg /usr/share/icons/breeze/actions/24/edit-select.svg /usr/share/icons/oxygen/16x16/actions/edit-select.png /usr/share/icons/oxygen/22x22/actions/edit-select.png /usr/share/icons/oxygen/48x48/actions/edit-select.png /usr/share/icons/oxygen/32x32/actions/edit-select.png then we can see that there are Oxygen icons for "edit-select" (altough they show only a generic image of a mouse arrow, unlike its Breeze equivalent, which shows a mouse arrow and a distinctive little circle).

"edit-select-none" and "edit-select-invert" are only included in Breeze and not standard icon names (see https://specifications.freedesktop.org/icon-naming-spec/0.8/ar01s04.html). Sooo.... what should we do? I really don't know. * change the icon names to standard ones (i couldn't find something suitable) * include these breeze icons as fallback in the Krusader package (will look ugly with other themes) * do nothing (always a lazy option) ?

@Toni if you agree, I would like to set this report as a duplicate of Bug 372966. If this bug is about Krusader using icons only included in Breeze, this is what 372966 is about. If there are icon-names is Oxygen which are somehow not used by Krusader it would be different though.
Thank you for your comments, Alex! > If this bug is about Krusader using icons only included in Breeze, this is what 372966 is about. > If there are icon-names is Oxygen which are somehow not used by Krusader it would be different though. After all that has been discussed, it seems that there are those problems: - Oxygen not having all the icons that Breeze has and Krusader uses (like "edit-select-none"); - Oxygen having a "edit-select" icon that shows only a generic image of a mouse arrow, unlike its Breeze equivalent, which shows a mouse arrow and a distinctive little circle. And maybe Krusader is doing a good job by not mixing Oxygen and Breeze icons. So this bug report would not be a 372966 duplicate, but a bug about the Oxygen icons and Krusader. Additionally somebody else could think that it would be better that Krusader would include Breeze icons as fallback in the Krusader package (though it would look ugly with other themes), then somebody could write here his opinion.
Well, if there are icons missing in Oxygen (or any other icon theme) which are needed by Krusader, it is more a general problem. I have thought about solving this and Bug 372966: Two assumptions I take for granted: * there should never be missing icons for any actions/buttons in the UI. It simply should not occur in any modern application. * mixing different icon sets in one application is just ugly and should also never happen. I can't even remember I have ever seen this anywhere. And I am really against taking files from another project (Breeze) and copying them into our project. This is an ugly design decision and leads to more work: figuring out which icons we need, which icons are obsolete, which icons changed and need to be updated. What's left is this (and only this) solution: We make Breeze an official dependency of Krusader. Because it is the only icon set which contains all needed icons. And we force using Breeze as icon set if it is installed in the code; regardless of what the user has set as icon set. And optionally: Show a warning message on Krusader startup if Breeze is not installed. Because in this case icons will be missing and the user maybe does not know why. Opinions?
> Opinions? As for me, I agree, Alex. This sounds reasonable. We just have to make sure that both Breeze and Breeze Dark will work correctly, but that will probably be no problem.
I agree, too!
Just in case: a bug report about the Oxygen icons was created (https://bugs.kde.org/show_bug.cgi?id=388691)
The issue is that Breeze uses Oxygen as fallback (because historically, Oxygen was considered 'complete', whereas Breeze was still evolving), but now the fallback order should get reversed. Users that use the Oxygen icons (e.g. me) will probably report it as a bug that Krusader no longer respects their icon theme choice, but they will understand that Oxygen is no longer maintained, and with reversed fallback, they would see a minimal amount of Breeze icons, instead of no icons.
As Andreas Kainz has updated Oxygen icons (very good!), Breeze and Oxygen have all the icons that Krusader needs, there are more details in: https://bugs.kde.org/show_bug.cgi?id=388691 https://commits.kde.org/oxygen-icons5/857400cb1a51f2287e4b6b285bba0f897066a6f7
Git commit 94ea5b69af14620abd4a44a13240ca9b2749641b by Nikita Melnichenko. Committed on 22/04/2018 at 22:00. Pushed by melnichenko into branch 'master'. Refactored and unified icon rendering, implemented per-icon fallback logic Merge branch 'fix-missing-icons' The merged branch contains implementation of per-icon fallback logic: 1. Search icon in the active icon theme — if found, use it. 2. Search it in the icon theme that is specified in Krusader config — if found, use it. 3. Search it in Breeze or Oxygen (in case any of these installed) — if found, use it. 4. Otherwise use a default "icon-missing" icon bundled with Krusader.
