Own drag icon with same color and font settings as the default drag icon in a Gtk.TreeView

I have a stackoverflow question with example code open with this: https://stackoverflow.com/q/52339893/4865723 The Gtk.TreeView implements a default drag icon. It use the background color of the TreeView, it's font and the complete row-content as string. I want the same (background-color,

I don't want to use colors defined by myself e.g. with RGB-values. I want to use colors from the system (Windows, Linux, ...) and/or the theme. For example I need the background color of a highlighted menu or list item. Is there a way? Can I also ask for fonts like this?

Cancel a Drag & Drop for some specific items in a Gtk.TreeView

I also opened this question on https://stackoverflow.com/q/51974845/4865723 I have a Gtk.TreeView here. Most but not all of the items should be able to be dragged & dropped. For example the first item should not be able to be dragged & dropped but it should be selectable. How can I realize this?
