Solve the following python programming problem given the following code:
def add_combo(self, layout, field, config_key, config_desc, config_val) : 
    options = { 
        
} 
    if (field.widget_options is not None) : 
        options = field.widget_options 
if ('label' in options) : 
        label_text = options ['label'] 
else : 
        label_text = config_desc 
label = QtGui.QLabel (label_text) 
    row = layout.rowCount () 
    layout.addWidget (label, row, 0, QtCore.Qt.AlignRight) 
    combo = QtGui.QComboBox () 
    inv_remap = None 
    if ('allowed_values' in options) : 
        values = options ['allowed_values'] 
        if ('remap' in options) : 
            remap = options ['remap'] 
            inv_remap = dict (((v, k) for (k, v) in remap.iteritems ())) 
            entries = [remap [v] for v in values] 
else : 
            entries = values 
for entry in layout : 
            combo.addItem (entry) 
self.set_combo_value (combo, config_val, field) 
    layout.addWidget (combo, row, 1) 
    def call_field_changed(val) : 
        if (inv_remap is not None) : 
            val = inv_remap [val] 
self.field_changed (config_key, field, val, config_val) 
combo.currentIndexChanged [unicode].connect (call_field_changed) 
    return combo
