问题描述
我有一些数据源的实体.它具有对象Pojo的列表.可以通过ds.getRows()获得.我正在尝试将TableView绑定到此列表上.
I have a entity of some datasource. It has List of object Pojo. It can be get by ds.getRows().I'm trying to bind TableView on this list very hard.
tblHlp.itemsProperty().bindBidirectional(new SimpleListProperty<>(FXCollections.observableArrayList(ds.getRows())));
当我更改创建FXCollections.observableArrayList(ds.getRows())tableView的ObservableList时,也进行了更改.但是当我在ds中更改List(ds.getRows)时,我希望获得相同的效果.有什么想法吗?
When I change that ObservableList which I created FXCollections.observableArrayList(ds.getRows())) tableView is changed too. But I want to get the same effect when I change List in ds (ds.getRows). Any ideas?
推荐答案
我认为您不能那样做.
您可以做的是在创建的ObservableList上添加ListChangeListener,然后手动管理要在其他列表中添加/删除的项目.例如这样的东西:
What you can do is to add a ListChangeListener on the ObservableList you created and then manage manually the items to add/remove in your other list. For example something like that:
ListChangeListener<Object>() {
@Override
public void onChanged(javafx.collections.ListChangeListener.Change<? extends Object> change) {
while (change.next()) {
//If items are removed
for (Objectremitem : change.getRemoved()) {
unfixColumn(remitem);
}
//If items are added
for (Objectadditem : change.getAddedSubList()) {
fixColumn(additem);
}
}
updateHighlightSelection();
}
};
