View Full Version : showing an image on selected row(GTK+)

March 3rd, 2006, 11:23 PM
I am trying to create a programm where I have a tree_view and can selected differentt rows. when i selectr a row a picture should be displayed with the rowname.png (for now).
so how can I do that?
I tried this one, but I dont exactly cant find out how to create a function that gets the name and displays then the picture.

void bild_aktualisieren(gchar name)

gchar picname;
/* neuen Pixbuf ins Bild einschreiben und dann
freigeben */
picname = sprintf("%s.png", name);
return shot = g_object_new(GTK_TYPE_IMAGE,"file", "picname", NULL);
// g_object_set(shot, "pixbuf", neuer_pixbuf, NULL);

void sagwas(GtkTreeSelection *auswahl, gpointer daten){

GtkTreeIter iter;
GtkTreeModel *model = NULL;

if(gtk_tree_selection_get_selected(auswahl, &model, &iter))
gchar *name;
gtk_tree_model_get(model, &iter, 1, &name, -1); /*immer mit -1 am Ende*/
g_print("Hallo %s\n",name);
this is how I call a single picture
shot = g_object_new(GTK_TYPE_IMAGE,"file", "bla2.png", NULL);

gtk_fixed_put (GTK_FIXED (fixed1), shot, 24, 16);
gtk_widget_set_size_request (shot, 376, 328);

its called by this
g_signal_connect(G_OBJECT(auswahl), "changed",G_CALLBACK(sagwas), NULL);

maybe someone can link me to an example for this
