改变行的背景颜色(或只是颜色)(javafx) [英] Changing background color (or just color) of row (javafx)
本文介绍了改变行的背景颜色(或只是颜色)(javafx)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有 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
:
I've a TableView
. I want to change background color of rows according to some condition. For instance, if balance (getBalance()
) is less than zero - set background color of that row to red. Here is my 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()));
推荐答案
使用 TableColumn#setCellFactory 方法。
请尝试以下代码(未经测试):
Use TableColumn#setCellFactory method.
Try the following code (not tested):
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("");
}
}
};
});
