Hi,
take a look at this code, maybe it helps:
ZZ
char *file_selector(char *title, GtkFileChooserAction fs_action, gboolean
local_only, gboolean show_hidden,
char *name, char *folder, char
*shortcut_folder)
{
GtkWidget *dialog;
char *tmp;
char *filename = NULL;;
tmp = g_locale_to_utf8((title) ? title : "", -1,NULL,NULL,NULL);
dialog = gtk_file_chooser_dialog_new (tmp,
/*parent_window*/ NULL,
fs_action,
GTK_STOCK_CANCEL,
GTK_RESPONSE_CANCEL,
GTK_STOCK_OPEN,
GTK_RESPONSE_ACCEPT,
NULL);
xfree(&tmp);
gtk_file_chooser_set_local_only(GTK_FILE_CHOOSER(dialog), local_only);
gtk_file_chooser_set_show_hidden(GTK_FILE_CHOOSER(dialog), show_hidden);
/* Returns a GsList *, not a char * */
/*gtk_file_chooser_set_select_multiple(GTK_FILE_CHOOSER(dialog),
select_multiple);*/
if (name) {
tmp = g_locale_to_utf8((name) , -1,NULL,NULL,NULL);
gtk_file_chooser_set_current_name(GTK_FILE_CHOOSER(dialog),
tmp);
xfree(&tmp);
}
if (folder) {
tmp = g_locale_to_utf8((folder) , -1,NULL,NULL,NULL);
gtk_file_chooser_set_current_folder(GTK_FILE_CHOOSER(dialog),
tmp);
xfree(&tmp);
}
if (shortcut_folder) {
tmp = g_locale_to_utf8((shortcut_folder) , -1,NULL,NULL,NULL);
gtk_file_chooser_add_shortcut_folder(GTK_FILE_CHOOSER(dialog),
tmp, NULL);
xfree(&tmp);
}
if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT) {
filename = gtk_file_chooser_get_filename(GTK_FILE_CHOOSER
(dialog));
}
gtk_widget_destroy (dialog);
return filename;
}
