Question

Can i store the unspecified type in GtkListStore? For instance, I want to store in one field – the field of int type and the field of GdkColor type ?

Answer 1

Me asked that It will be set the G_TYPE_VALUE type of field

#include <gtk/gtk.h>

int main (int argc, char * argv[])
{
  gtk_init(&argc, &argv);

  GtkListStore* store = gtk_list_store_new(1, G_TYPE_VALUE);
  GValue v = { 0 };
  GtkTreeIter iter;
  gtk_list_store_append(store, &iter);
  g_value_init(&v, G_TYPE_INT);
  g_value_set_int(&v, 10);
  GValue gv = { 0 };
  g_value_init(&gv, G_TYPE_VALUE);
  g_value_set_boxed(&gv, &v);
  gtk_list_store_set_value(store, &iter, 0, &gv);

  GValue gv2 = { 0 };
  gtk_tree_model_get_value((GtkTreeModel*)store, &iter, 0, &gv2);
  printf("gv2 holds %s\n", g_type_name(G_VALUE_TYPE(&gv2)));
  GValue * gv3 = (GValue*)g_value_get_boxed(&gv2);
  printf("gv3 holds %s\n", g_type_name(G_VALUE_TYPE(gv3)));

  int int_v = g_value_get_int(gv3);
  printf("int_v = %d\n", int_v);

  return 0;
}
