Displaying pictures on buttons

Hello. I cannot figure out the problem of displaying pictures attached to ActionButtons. These pictures are displayed or not. how to do it correctly so that the pictures are guaranteed to be displayed?
 
This is what the interface looks like in QtDesigner:
 

This is what it looks like after loading the configuration
 

 

is this
../../../Рабочий стол/test/img/zoomplus.png
really the path name?

<normaloff>../../../Рабочий стол/test/img/zoomplus.png</normaloff>../../../Рабочий стол/test/img/zoomplus.png</iconset>

Greetings. relative path to image files: ./img. Full path to image files: /home/ddd/linuxcnc/configs/test/img/

Well it looks like something went wrong as thats a pretty odd looking path.
Try editing the file to the right path and see what happens.
Make a back up though

I attach an archive with a config. maybe someone will be able to suggest the right direction to find a solution to the problem

Open any file with F12. qss or create your resource and style files. Take a close look at how this is done in qt_axis.
