Hi,
I would like to use the style information from the textview widget in another
context. I want
to retrieve the text foreground color and the background color as it would be
used in a textview widget
and use this style information for rendering inside a drawing area. I figured
out that I can modify the
style by adding a style class with gtk_style_context_add_class (), but the
textview background
color seems to be specific to the textview widget.
In the adwaita scheme css:
GtkTextView {
background-color: #f6f6f6; }
GtkTextView:backdrop {
background-color: #f6f6f6; }
Is there a way to retrieve this information of the background-color similar to
the class mechanism?
I would need the same style context as if I was in a textview widget.

I don't have a complete solution for you, but you can get the background
color from gtk_style_context_get_background_color().
For example...
GtkWidget *win = NULL;
GdkRGBA color1;
GdkRGBA color2;
GtkStyleContext *context1;
...
...
gtk_widget_show_all (win);
context1 = gtk_widget_get_style_context (win);
gtk_style_context_get_background_color(context1, GTK_STATE_NORMAL, &color1);
printf("%f\n%f\n%f\n", ( color1.red ), ( color1.green), ( color1.blue));
The colors are decimal numbers between 0.0 and 1.0. To change the
background color...
color2.red = 1.0;
color2.green = 0.1;
color2.blue = 0.1;
color2.alpha = 1.0;
gtk_widget_override_background_color (win, GTK_STATE_NORMAL, &color2);
