Since dolphin got updated to version 15.08 I don't see any icons in dolphin anymore when opening it in openbox, which is my standard window manager (standalone). Even when entering the properties of a folder in order to change the icon there no icon is visible in the properties window. Under kwin/plasma there is no problem, all icons show up as expected. When starting dolphin from console there is one message occuring only in openbox:
QPainter::begin: Paint device returned engine == 0, type: 2

I am using Arch linux,
uname -a
Linux bumblebee 4.1.6-1-ARCH #1 SMP PREEMPT Mon Aug 17 08:52:28 CEST 2015 x86_64 GNU/Linux
openbox --version
Openbox 3.6.1

If you need more info about my system I'll gladly provide it.

What could be the problem here? Thanks!

There's likely no QPA loaded, so no icon theme available.

Try

Code: Select all

XDG_CURRENT_DESKTOP=kde dolphin
QT_QPA_PLATFORM_THEME=kde dolphin
QT_QPA_PLATFORM=kde dolphin


One of them should likely do

Great, thanks a lot!!! The first one did the trick!

Hmm. That's not really a solution. If you set XDG_CURRENT_DESKTOP to kde, qt will load the kde platform integration plugin ... which will for example always use SNI. If you run a desktop without SNI, this doesn't work (and currently even crashes horribly, see https://git.reviewboard.kde.org/r/126212/). So what does one do to get icons in KDE apps outside Plasma?

Edit: Ok, one solution is using "qt5ct" to select an icon theme and a style, and then

Code: Select all

export QT_QPA_PLATFORMTHEME="qt5ct"

. That works and shouldn't have the problem mentioned above.

I am in fluxbox and to have breeze icons in Dolphin i used this solution:

angelo@jerusalem ~ > cd /usr/share/icons
angelo@jerusalem /usr/share/icons > sudo mv hicolor hicolor_backup
angelo@jerusalem /usr/share/icons > sudo ln -s breeze hicolor

Test it:
angelo@jerusalem ~ > XDG_CURRENT_DESKTOP=kde dolphin

add then
export XDG_CURRENT_DESKTOP=kde
in your .profile

Do not use XDG_CURRENT_DESKTOP=kde outside KDE. It will explode in some cases. Instead, use qt5ct or so. I don't like the situation either
