I have the following code that works fine to set background and foreground colors for a GtkTextview:
static void
setColor(GtkWidget * widget) {
auto style_context = gtk_widget_get_style_context (widget);
gtk_style_context_add_class(style_context, GTK_STYLE_CLASS_VIEW );
auto css_provider = gtk_css_provider_new();
GError *error=NULL;
auto data = g_strdup_printf("\
* {\
background-color: black;\
color: white;\
}\
*:selected {\
background-color: blue;\
color: yellow;\
}\
");
gtk_css_provider_load_from_data (css_provider, data, -1, &error);
g_free(data);
if (error){
ERROR("gtk_css_provider_load_from_data: %s\n", error->message);
g_error_free(error);
return;
}
gtk_style_context_add_provider (style_context,
GTK_STYLE_PROVIDER(css_provider),
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
}
The result is that both normal and selected text color have black background and white foreground.
Why doesn't the selected text appear in yellow/blue?
Any pointer to an example file would be much appreciated.
