JavaFx Tableview checkbox requires focus












0















I implemented boolean representation in my tableView as checkbox. It works fine in general but very irritating fact is that it requires row to be focused (editing) to apply change of checkbox value. It means I first have to double click on the field and then click checkbox.



How to make checkbox change perform onEditCommit right away?



public class BooleanCell<T> extends TableCell<T, Boolean> {
private CheckBox checkBox;

public BooleanCell() {
checkBox = new CheckBox();
checkBox.selectedProperty().addListener(new ChangeListener<Boolean>() {
public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
if (isEditing())
commitEdit(newValue == null ? false : newValue);
}
});
setAlignment(Pos.CENTER);
this.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
this.setEditable(true);
}

@Override
public void updateItem(Boolean item, boolean empty) {
super.updateItem(item, empty);
if (empty) {
setGraphic(null);
} else {
checkBox.setSelected(item);
setGraphic(checkBox);
}
}


}

I'm not sure about the rest of your implementation, but I assume you do not have your TableView set to editable:



tableView.setEditable(true);




On a side note, you could easily use a CheckBoxTableCell instead of implementing your own (BooleanCell).



Here is a very simple application you can run to see how this works. Each CheckBox may be clicked without first focusing the row and its value updates your underlying model as well (which you can see by clicking the "Print List" button).



import javafx.application.Application;
import javafx.beans.property.BooleanProperty;

public class CheckBoxTableViewSample extends Application {

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

@Override
public void start(Stage primaryStage) {

// Simple interface
VBox root = new VBox(5);
root.setPadding(new Insets(10));
root.setAlignment(Pos.CENTER);

// List of sample items
ObservableList<MyItem> myItems = FXCollections.observableArrayList();
myItems.addAll(
new MyItem(false, "Item 1"),
new MyItem(false, "Item 2"),
new MyItem(true, "Item 3"),
new MyItem(false, "Item 4"),
new MyItem(false, "Item 5")
);

// Create TableView
TableView<MyItem> tableView = new TableView<MyItem>();

// We need the TableView to be editable in order to allow each CheckBox to be selectable
tableView.setEditable(true);

// Create our table Columns
TableColumn<MyItem, Boolean> colSelected = new TableColumn<>("Selected");
TableColumn<MyItem, String> colName = new TableColumn<>("Name");

// Bind the columns with our model's properties
colSelected.setCellValueFactory(f -> f.getValue().selectedProperty());
colName.setCellValueFactory(f -> f.getValue().nameProperty());

// Set the CellFactory to use a CheckBoxTableCell
colSelected.setCellFactory(param -> {
return new CheckBoxTableCell<MyItem, Boolean>();
});

// Add our columns to the TableView
tableView.getColumns().addAll(colSelected, colName);

// Set our items to the TableView
tableView.setItems(myItems);

// Create a button to print out our list of items
Button btnPrint = new Button("Print List");
btnPrint.setOnAction(event -> {
System.out.println("-------------");
for (MyItem item : myItems) {
System.out.println(item.getName() + " = " + item.isSelected());
}
});

root.getChildren().addAll(tableView, btnPrint);

}
}

// The name of our Item
private final StringProperty name = new SimpleStringProperty();

public MyItem(boolean selected, String name) {
this.selected.setValue(selected);
this.name.set(name);
}

public boolean isSelected() {

}

public BooleanProperty selectedProperty() {

  • That's what I was looking for! Can you also guide what would be the best way to get some callback? Something like onEditCommit. I did it by implementing new Callback() {...}.call(Integer), but I dont think it's the best way. Maybe adding onEditCommit in fxml somehow?

  • That's a bit too broad, @MateuszGaweł. It depends on what your needs are for the commit. If you simply want to update the selected property of the MyItem object, that is already done with the CheckBoxTableCell. You might want to ask a separate question regarding that.

  • That's what I was looking for! Can you also guide what would be the best way to get some callback? Something like onEditCommit. I did it by implementing new Callback() {...}.call(Integer), but I dont think it's the best way. Maybe adding onEditCommit in fxml somehow?

  • That's a bit too broad, @MateuszGaweł. It depends on what your needs are for the commit. If you simply want to update the selected property of the MyItem object, that is already done with the CheckBoxTableCell. You might want to ask a separate question regarding that.
