JavaFX 2.1 TableView refresh items

Solution 1:

Workaround:

 tableView.getColumns().get(0).setVisible(false);
 tableView.getColumns().get(0).setVisible(true);

Solution 2:

Since JavaFX 8u60 you can use(assuming tableView is an instance of TableView class):

tableView.refresh();

From the documentation:

Calling refresh() forces the TableView control to recreate and repopulate the cells necessary to populate the visual bounds of the control. In other words, this forces the TableView to update what it is showing to the user. This is useful in cases where the underlying data source has changed in a way that is not observed by the TableView itself.

Solution 3:

I had a similar problem with refreshing. My solution was to restrict the operations on the ObservableList to those which work correctly with bind().

Assume ObservableList obsList is the underlying list for the TableView.

Then
obsList.clear() (inherited from java.util.List<>) will not update the TableView correctly but.

Also calling setItem(obsList) did not work to trigger a refresh...but...

obsList.removeAll(obsList) (overwritten by ObservableList) works fine because it fires the changeEvent correctly.

Refilling a list with completely new content then works as follows:

obsList.removeAll(obsList);
obsList.add(...); //e.g. in a loop...

obsList.removeAll(obsList);
FXCollections.copy(obsList, someSourceList)

Solution 4:

UPDATE:
Finally tableview refreshing is resolved in JavaFX 8u60, which is available for early access.

About refreshing see the Updating rows in Tableview.
And about the blank column see the JavaFx 2 create TableView with single column. Basically it is not a column, i.e. you cannot select the item clicking on this blank column items. It is just a blank area styled like a row.

UPDATE: If you are updating the tableView via reseller_table.setItems(data) then you don't need to use SimpleStringProperty. It would be useful if you were updating one row/item only. Here is a working full example of refreshing the table data:

import java.util.ArrayList;
import java.util.List;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Dddeb extends Application {

    public static class Product {
        private String name;
        private String code;

        public Product(String name, String code) {
            this.name = name;
            this.code = code;
        }

        public String getCode() {
            return code;
        }

        public void setCode(String code) {
            this.code = code;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
    }

    private TableView<Product> productTable = new TableView<Product>();

    @Override
    public void start(Stage stage) {

        Button refreshBtn = new Button("Refresh table");
        refreshBtn.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent arg0) {
                // You can get the new data from DB
                List<Product> newProducts = new ArrayList<Product>();
                newProducts.add(new Product("new product A", "1201"));
                newProducts.add(new Product("new product B", "1202"));
                newProducts.add(new Product("new product C", "1203"));
                newProducts.add(new Product("new product D", "1244"));

                productTable.getItems().clear();
                productTable.getItems().addAll(newProducts);
                //productTable.setItems(FXCollections.observableArrayList(newProducts));
            }
        });

        TableColumn nameCol = new TableColumn("Name");
        nameCol.setMinWidth(100);
        nameCol.setCellValueFactory(new PropertyValueFactory<Product, String>("name"));

        TableColumn codeCol = new TableColumn("Code");
        codeCol.setCellValueFactory(new PropertyValueFactory<Product, String>("code"));

        productTable.getColumns().addAll(nameCol, codeCol);
        productTable.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

        // You can get the data from DB
        List<Product> products = new ArrayList<Product>();
        products.add(new Product("product A", "0001"));
        products.add(new Product("product B", "0002"));
        products.add(new Product("product C", "0003"));

        //productTable.getItems().addAll(products);
        productTable.setItems(FXCollections.observableArrayList(products));

        final VBox vbox = new VBox();
        vbox.setSpacing(5);
        vbox.getChildren().addAll(productTable, refreshBtn);

        Scene scene = new Scene(new Group());
        ((Group) scene.getRoot()).getChildren().addAll(vbox);
        stage.setScene(scene);
        stage.setWidth(300);
        stage.setHeight(500);
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Note that

productTable.setItems(FXCollections.observableArrayList(newProducts));

and

productTable.getItems().clear();
productTable.getItems().addAll(newProducts);

are almost equivalent. So I used the one to fill the table for the first time and other when the table is refreshed. It is for demo purposes only. I have tested the code in JavaFX 2.1. And finally, you can (and should) edit your question to improve it by moving the code pieces in your answer to your question.

Solution 5:

I finally found an ugly workaround to refresh all rows.

void refreshTable() {
    final List<Item> items = tableView.getItems();
    if( items == null || items.size() == 0) return;

    final Item item = tableView.getItems().get(0);
    items.remove(0);
    Platform.runLater(new Runnable(){
        @Override
        public void run() {
            items.add(0, item);
        }
    });
 }
