Dear all,
thanks a lot for all your comments,
I played a little bit with cario and it works out quit well:

Dear all,
because of my lazy programming style I sometimes forget or overwirte the comma

an update frequency about 400Hz is absolutely not necessary,

This gives an acceptable picture, even if I use later progress bars for

Dear all,

Different Objects can be added or removed to the treestore, each existing

My current simple solution is as follows:
I use the gtk_tree_model_foreach() function and pass some user data with the
current major number of the tree-path.
Inside the foreach-function I use gtk_tree_path_to_string, where I check if the
first number is identical to the user data.

You mean using a label instead of a text view then?
Or can I use gtk_label_set_markup() together with a text-buffer?
A label can use Pango-Markup language, but I didn't find a way to make a
newline using a markup.
When parsing xml, all line-ends are ignored.
