This question goes further where JavaFX: BooleanBindings in bind with multiple EasyBind maps stopped.
I would like to extend the row factory a bit further: In table 1 the products are presented with 1 piece a row, so there could be multiple rows for 1 product object. Now I only want to disable a row, if the amount in table 2 is equal to the summed amounts of the rows. For example: Product(SKU: P1) has three lines in table1 (all representing amount 1). If Product(SKU: P1) had amount = -2 in table2, 2 rows of this product object need to be disabled in table1. One still needs to be enabled, doesn't matter which one of the three.
I have the following code at the moment:
table1.setRowFactory(tv -> {
TableRow<Product> row = new TableRow<>();
row.disableProperty().bind(Bindings.createBooleanBinding(
() -> row.getItem() != null && (row.getItem().getSKU().startsWith("C") ||
(skuAmountLookup.containsKey(row.getItem().getSKU()) &&
-skuAmountLookup.get(row.getItem().getSKU()) <
amounts[SKUs.indexOf(row.getItem().getSKU())] )),
skuAmountLookup,
row.itemProperty()));
return row;
});
where skuAmountLookup is:
skuAmountLookup = table2.getItems().stream().collect(
Collectors.toMap(Product::getSKU, Product::getAmount, (x, y) -> y,
() -> FXCollections.observableHashMap()));
This only disables the rows when the total amount is table 1. You could change amounts[SKUs.indexOf(row.getItem().getSKU())] to 0, which will disable all the rows when only one of the products is present.
My question is: how can I change the row factory in such a way that the disableProperty of another row is taken into account?
