I need to detect double clicks on a row of a TableView
.
How can I listen for double clicks on any part of the row and get all data of this row to print it to the console?
TableView<MyType> table = new TableView<>();
//...
table.setRowFactory( tv -> {
TableRow<MyType> row = new TableRow<>();
row.setOnMouseClicked(event -> {
if (event.getClickCount() == 2 && (! row.isEmpty()) ) {
MyType rowData = row.getItem();
System.out.println(rowData);
}
});
return row ;
});
Here is a complete working example:
import java.util.Random;
import java.util.function.Function;
import javafx.application.Application;
import javafx.beans.property.IntegerProperty;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.beans.value.ObservableValue;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableRow;
import javafx.scene.control.TableView;
import javafx.stage.Stage;
public class TableViewDoubleClickOnRow extends Application {
@Override
public void start(Stage primaryStage) {
TableView<Item> table = new TableView<>();
table.setRowFactory(tv -> {
TableRow<Item> row = new TableRow<>();
row.setOnMouseClicked(event -> {
if (event.getClickCount() == 2 && (! row.isEmpty()) ) {
Item rowData = row.getItem();
System.out.println("Double click on: "+rowData.getName());
}
});
return row ;
});
table.getColumns().add(column("Item", Item::nameProperty));
table.getColumns().add(column("Value", Item::valueProperty));
Random rng = new Random();
for (int i = 1 ; i <= 50 ; i++) {
table.getItems().add(new Item("Item "+i, rng.nextInt(1000)));
}
Scene scene = new Scene(table);
primaryStage.setScene(scene);
primaryStage.show();
}
private static <S,T> TableColumn<S,T> column(String title, Function<S, ObservableValue<T>> property) {
TableColumn<S,T> col = new TableColumn<>(title);
col.setCellValueFactory(cellData -> property.apply(cellData.getValue()));
return col ;
}
public static class Item {
private final StringProperty name = new SimpleStringProperty();
private final IntegerProperty value = new SimpleIntegerProperty();
public Item(String name, int value) {
setName(name);
setValue(value);
}
public StringProperty nameProperty() {
return name ;
}
public final String getName() {
return nameProperty().get();
}
public final void setName(String name) {
nameProperty().set(name);
}
public IntegerProperty valueProperty() {
return value ;
}
public final int getValue() {
return valueProperty().get();
}
public final void setValue(int value) {
valueProperty().set(value);
}
}
public static void main(String[] args) {
launch(args);
}
}
