我是TableView
。我想根据某些条件更改行的背景颜色。例如,如果balance(getBalance()
)小于零 - 将该行的背景颜色设置为红色。这是我的setCellValueFactory
:
tc_proj_number.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getId().toString()));
tc_proj_date.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getValueDate().toInstant().atZone(ZoneId.systemDefault()).toLocalDate().toString()));
tc_proj_amount.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getBalance().setScale(2).toPlainString()));
tc_proj_comment.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getComment()));
答案 0 :(得分:3)
使用TableColumn#setCellFactory方法 请尝试以下代码(未经测试):
tc_proj_amount.setCellFactory(column -> {
return new TableCell<Account, String>() {
@Override
protected void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (item == null || empty) {
setText(null);
} else {
setText(item);
// Style row where balance < 0 with a different color.
BigDecimal balance = new BigDecimal(item);
TableRow currentRow = getTableRow();
if (balance.compareTo(BigDecimal.valueOf(0)) < 0) {
currentRow.setStyle("-fx-background-color: red;");
} else currentRow.setStyle("");
}
}
};
});
