GtkBox Styling problem.

[Yaa101 <yaa101 xs4all nl>]

Hi all,

Maybe somebody can help me with this:

I have a display problem with some widgets, I have tried several themes
to see if the theme was broken this way, but the problem persists.

I have a Gtk.Notebook and on one of the (white) pages I have

1. A horizontal box
2. 3 vertical boxes in it to serve as 3 panels
3. In panel one I have a horizontal box that contains a vertical box
with buttons and a treeview that serves as listbox (combined to make 1
widget)
4. In the middle box I have some command buttons.
5. In the right box I have a treeview that serves as listbox and
underneith a filechooser button(combined to make 1
widget)


All the functions of these widgets work perfectly together.
However, the frames of the treeviews fall away into the background of
the notebook page.
Also I am not able to style any of the boxes, it seems as if they lie
under the page instead of on the page.

I tried the following example, can somebody tell me if I do something
wrong? It tries to set the background color of the horizontal box that
contains all the boxes and widgets and should change the white from the
underlying page to the color of choice, in this case black. I tried
different provider priorities too. I tried background and
background-color.


let styleContext = hbox.get_style_context();
styleContext.add_class("blah");

let style = '.blah { background-color: #000000; }';
        
let cssProvider = new Gtk.CssProvider();
cssProvider.load_from_data(style);

styleContext.add_provider(cssProvider,
Gtk.STYLE_PROVIDER_PRIORITY_USER);



Let me be clear, I do not want to change styling, but leaving the user
with broken widget styling is no option, it is ugly and keeps the
widgets from looking intuitive.
