 Hello all.
 
 Just a quick question: is it possible to use Glade2 when new widgets
 (from 2.4) are needed?

BTW, don't you think Glade should support plugins? Then
gtk-gl/gtkext/gtkwhatever - programmers would provide .xml files
describing custom widgets

Re: glib API for iterating the g_hash_table

 Hi,
 
 Is there any API for iterating GHashTable?
 
 I only see the the g_hash_table_foreach() here. But sometimes people may
 like to iterate through a hash table and stop the iteration when certain
 conditions are met.
 
 Currently, there is g_hash_table_size(), we could easily add iteration
 by providing the following two new APIs,
 
 gconstpointer g_hash_table_get_key(GHashTable *hash_table, int pos);
 gconspointer g_hash_table_get_value(GHashTable *hash_table, int pos);
 
 The two APIs allows one to iterate the hash table, for example,
 
 for (i = 0; i  g_hash_table_size(hash_table); i++) {
  gconstpointer value = g_hash_table_get_value(hash_table, i);
 
  /* Do some processing here */
  if (is_match(value))
return TRUE;
 }
 
 Should we add the APIs?


I made something similar, but for GData:


typedef struct _GQDPair GQDPair;
struct _GQDPair
{
GQuarkquark;
gpointer  data;
};

GArray * g_datalist_pairs(GArray *a, GData **dl);

#define GQDq(qp, i) g_array_index(qp, GQDPair, i).quark
#define GQDd(qp, i) g_array_index(qp, GQDPair, i).data



/* GQuark/gpointer pairs from GDataList  */

void
on_keyval2GArray(GQuark key, gpointer *data, GArray *a)
{
GQDPair p;

p.quark = key;
p.data = data;
g_array_append_val(a, p);
}

GArray *
g_datalist_pairs(GArray *a, GData **dl)
{
if (a)
{
g_array_set_size(a, 0);
}
else
a = g_array_new(TRUE, FALSE, sizeof(GQDPair));

g_datalist_foreach(dl, (GDataForeachFunc)on_keyval2GArray, a);

return a;
}
