OK, now works:
if(css_provider == NULL){
css_provider = gtk_css_provider_new();
apply_css(gtk_builder_get_object(builder,"window_Main"),css_provider);
g_object_unref(css_provider);
}
gtk_css_provider_load_from_data (css_provider,"#label_Sensors {
color: red; }",-1,NULL);
static void apply_css(GtkWidget *widget, GtkStyleProvider *provider)
{
gtk_style_context_add_provider(gtk_widget_get_style_context(widget),
GTK_STYLE_PROVIDER(provider),G_MAXUINT);
if(GTK_IS_CONTAINER(widget))
gtk_container_forall(GTK_CONTAINER(widget),(GtkCallback)
apply_css,provider);
}
I need to create a different selector for each of label that i want to
change to red color?
