Hallo!
(I'm trying this for the second time, for whatever reason the forum thought my question was not important enough and deleted it when I tried to preview.)
We finally created a custom widget with Qooxdoo and the LCA of RAP. While researching the possibilities we are now facing another problem. How do you register images in RAP to be used in Qooxdoo?
Now RAP does this inside org.eclipse.swt.internal.widgets.displaykit.ClientResources this way:
String name = "resource/widget/rap/ctabfolder/maximize.gif";
IResourceManager resourceManager = RWT.getResourceManager();
resourceManager.register(name, openResourceStream(name));
When accessing the file in Qooxdoo, it uses this approach:
maxIcon = "widget/ctabfolder/maximize.gif";
this.maxButton.setIcon(maxIcon);
So why did the path of the picture change? What is happening internally while registering? And how would we go about registering our own images? (Recreating the above scenario inside our own plug-in didn't work at all.)
Thank you for your kind help.

Probably, the solution will be to keep these images in the "widget that
is used to build many other widgets". Other widgets will get the images
from it. For me it sounds like WidgetsBuilder#getDecorationImage,
WidgetsBuilder#getErrorImage
Best,

That's what we want to do, but the Decoration has no Java counterpart, so can only access the images via Qooxdoo, and that is not working so far.

But this way each of the other widgets would have to set the image manually, after getting it from the WidgetsBuilder.
