Dynamic version:
...
static GtkCssProvider* provider = NULL;
static void
set_label_color(GtkWidget* label, const char* color)
{
const char* format = "label { color: %s; }";
size_t length = strlen(format) - 2 + 1;
char style[length];
sprintf(style, format, color);
if (provider == NULL) {
/* only create and add the provider the first time */
provider = gtk_css_provider_new();
gtk_style_context_add_provider(
gtk_widget_get_style_context(label),
GTK_STYLE_PROVIDER(provider),
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
g_object_unref(provider);
}
gtk_css_provider_load_from_data(provider, style, -1, NULL);
}
...
This might not be ideal in all situations. Just make sure you don't
create a new provider everytime you set a new color. Hope that helps.
