set_where_condition in Comboboxdelegate with selected value in another comboboxdelegate

I have two comboboxdelegates . 

 BlGenericComboBoxDelegate *cbd_id_tipo_tubo = new BlGenericComboBoxDelegate(mainCompany(), this);
    cbd_id_tipo_tubo->set_foreign_table("presu.tipo_tubo", "id", "tipo");
    cbd_id_tipo_tubo->set_foreign_field(columnNumber("id_tipo_tubo"), "id_tipo_tubo");
    cbd_id_tipo_tubo->setAllowNull(false);
    cbd_id_tipo_tubo->initialize("_tubo");
    mui_list->setItemDelegateForColumn(columnNumber("_tubo"), cbd_id_tipo_tubo);




BlGenericComboBoxDelegate *cbd_id_tipo_medida = new BlGenericComboBoxDelegate(mainCompany(), this);
    cbd_id_tipo_medida->set_foreign_table("presu.medidas_tipo_tubo","id", "medida");
cbd_id_tipo_medida->set_foreign_field(columnNumber("id_medidas_tipo_tubo"), "id_medidas_tipo_tubo"); 

cbd_id_tipo_medida->set_where_condition( 

**AQUI VALOR DEL PRIMER COMBO (id_tipo_tubo));

    cbd_id_tipo_medida->setAllowNull(false);
    cbd_id_tipo_medida->initialize("_medida");
    mui_list->setItemDelegateForColumn(columnNumber("_medida"), cbd_id_tipo_medida);

These combobox appear in a line of a sub-form Qtableview , and I want the item selected in the first combobox to be the where of the second.

I've tried with currenttext and so on, but they are combobox , not comboboxdelegate and I can not get the id_tipo_tubo of the first comboboxdelegate .

Thanks

In my case, it is solved in this way. Since the reference of the id column of the foreign key of the combobox was missing.

Adding this line in the combobox, it is solved. 

cbd_id_tipo_medida->set_filter_id("id_tipo_tubo", "id_tipo_tubo", true);
