To: Simon McVittie <<a href="mailto:simon.mcvittie@collabora.co.uk">simon.mcvittie@collabora.co.uk</a>> Thanks. Well. I managed to get my code alittle more functional. Made a xchat version, and a c version for debuging the code. But I have two values I can't find the field type for. Your code <div class="im"> /* the result of this function is only suitable for debug output */ gchar *tmp = g_strdup_value_contents (val); printf ("%s -> unhandled type %s with value %s", key, G_VALUE_TYPE_NAME (value), tmp); g_free (tmp); } </div>It works, but prints NULL for the second %s. The two fields I am tring to get the type of is filesize and length. Running you code outputs. file-size -> unahndled type (null) with value 17578504. I have tried to guess the type such as int uint long etc... No Luck so I ended up using ti.fs = g_strdup_value_contents (val); But using that. It won't let me do any math on it. I want to take that number it outputs which is ofcourse a filesize number and divide it by 1048576 for a value of 16.764168. Then I can do a sprintf("%1.2f, "var here") on it to make out put 16.76 then take on MB. I am not sure how to go about getting the field type. hmm I even tried looking in the banshee-1 source code which is C#. I must be missing something here. x.x Maby you have an answer. ///////////////////////////////////////////////////////////////////////////////////////////////////<div class="im"> #include <stdio.h> #include <dbus/dbus-glib.h> #include <string.h> </div>const gchar *mt1a; struct TrackInfo { const gchar *album; const gchar *artist; const gchar *name; const gchar *mt; const gchar *length; const gchar *br; const gchar *fs; }; struct TrackInfo ti; static void get_value (GHashTable *table, gpointer k, gpointer data) { //gpointer v; const GValue *value; const gchar *key = k; const GValue *val = g_hash_table_lookup(table, key);<div class="im"> if (G_VALUE_HOLDS_STRING (val)) { </div> if (key == "album") { ti.album = g_value_get_string (val); printf("Album: %s\n", ti.album); } if (key == "artist") { ti.artist = g_value_get_string (val); printf("Artist: %s\n", ti.artist); } if (key == "name") { <a href="http://ti.name" target="_blank">ti.name</a> = g_value_get_string (val); printf("Track Title: %s\n", <a href="http://ti.name" target="_blank">ti.name</a>); } if (key == "mime-type") { <a href="http://ti.mt" target="_blank">ti.mt</a> = g_value_get_string (val); char *mt1; mt1=strrchr(<a href="http://ti.mt" target="_blank">ti.mt</a>,'/'); if (mt1) mt1++; else mt1=<a href="http://ti.mt" target="_blank">ti.mt</a>; mt1a=mt1; printf("Mime-Type: %s\n", mt1); } } if (G_VALUE_HOLDS_INT (val)) { if (key == "bit-rate") { <a href="http://ti.br" target="_blank">ti.br</a> = g_value_get_int (val); printf("Bit-Rate: %u\n", <a href="http://ti.br" target="_blank">ti.br</a>); } } if (key == "length") { ti.length = g_strdup_value_contents (val); printf("Length: %s\n", ti.length); } if (key == "file-size") { ti.fs = g_strdup_value_contents (val); printf("File-Size: %s\n", ti.fs);<div class="im"> } } static void print_hash_value (gpointer k, gpointer v, gpointer data) { const gchar *key = k; const GValue *val = v; </div> const GValue *value;<div class="im"> if (G_VALUE_HOLDS_STRING (val)) { printf ("%s -> %s\n", key, g_value_get_string (val)); } else if (G_VALUE_HOLDS_UINT (val)) { printf ("%s -> %u\n", key, g_value_get_uint (val)); } </div> else if (G_VALUE_HOLDS_INT (val)) { printf ("%s -> %u\n", key, g_value_get_int (val));<div class="im"> } /* ... insert any more types you might need here ... */ else { /* the result of this function is only suitable for debug output */ gchar *tmp = g_strdup_value_contents (val); </div> printf ("%s -> unhandled type %s with value %s\n", key, G_VALUE_TYPE (value), tmp); g_free (tmp); } } <div class="im"> int main (int argc, char **argv) { DBusGConnection *connection; GError *error; DBusGProxy *proxy; GHashTable* table; </div><div class="im"> g_type_init (); error = NULL; connection = dbus_g_bus_get (DBUS_BUS_SESSION, &error); if (connection == NULL) { g_printerr ("Failed to open connection to bus: %s\n", error->message); g_error_free (error); exit (1); } /* Create a proxy object for the "bus driver" (name "org.bansheeproject.Banshee") */ proxy = dbus_g_proxy_new_for_name (connection, "org.bansheeproject.Banshee", "/org/bansheeproject/Banshee/PlayerEngine", "org.bansheeproject.Banshee.PlayerEngine"); /* Call GetCurrentTrack method, wait for reply */ error = NULL; if (!dbus_g_proxy_call (proxy, "GetCurrentTrack", &error, G_TYPE_INVALID, dbus_g_type_get_map("GHashTable", G_TYPE_STRING, G_TYPE_VALUE), &table, G_TYPE_INVALID)) { g_printerr ("Error: %s\n", error->message); g_error_free (error); exit (1); } /* Print the results */ </div> get_value(table,"album", NULL); get_value(table,"artist", NULL); get_value(table,"name", NULL); get_value(table,"length", NULL); get_value(table,"bit-rate", NULL); get_value(table,"file-size", NULL); get_value(table,"mime-type", NULL); //printf("Album: %s Artist: %s Title: %s [%s|%u Kbps|%s]\n", ti.album, ti.artist, <a href="http://ti.name" target="_blank">ti.name</a>, ti.length, <a href="http://ti.br" target="_blank">ti.br</a>, mt1a); //g_hash_table_foreach (table, print_hash_value, NULL);<div class="im"> //banshee_hash_str(table, "album", ti->album); g_object_unref (proxy); return 0; } </div>////////////////////////////////////////////////////////////////////////////////<div> <div></div><div class="h5"> <div class="gmail_quote">On Wed, Apr 15, 2009 at 6:24 AM, Simon McVittie <<a href="mailto:simon.mcvittie@collabora.co.uk" target="_blank">simon.mcvittie@collabora.co.uk</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>On Tue, 14 Apr 2009 at 20:43:01 -0500, Fujitaka Daidouji wrote: > static void print_hash_value (gpointer key, gpointer val, gpointer data) > { > printf ("%s -> %s\n", (char *) key, (char *) val); > } </div>No, val points to a GValue, not a string.
