In my Java Desktop Application I have a TableView in which I want to have a column with CheckBoxes.
I did find where this has been done on Jonathan Giles's website http://www.jonathangiles.net (the page where this was published in 2011 is no longer active so I removed the old link from the post), However, the download is not available and Jonathan Giles did not answer my email, so I thought I'd ask...
How do I put a CheckBox in a cell of my TableView?
You need to set a CellFactory on the TableColumn.
For example:
Callback<TableColumn<TableData, Boolean>, TableCell<TableData, Boolean>> booleanCellFactory =
new Callback<TableColumn<TableData, Boolean>, TableCell<TableData, Boolean>>() {
@Override
public TableCell<TableData, Boolean> call(TableColumn<TableData, Boolean> p) {
return new BooleanCell();
}
};
active.setCellValueFactory(new PropertyValueFactory<TableData,Boolean>("active"));
active.setCellFactory(booleanCellFactory);
class BooleanCell extends TableCell<TableData, Boolean> {
private CheckBox checkBox;
public BooleanCell() {
checkBox = new CheckBox();
checkBox.setDisable(true);
checkBox.selectedProperty().addListener(new ChangeListener<Boolean> () {
public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
if(isEditing())
commitEdit(newValue == null ? false : newValue);
}
});
this.setGraphic(checkBox);
this.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
this.setEditable(true);
}
@Override
public void startEdit() {
super.startEdit();
if (isEmpty()) {
return;
}
checkBox.setDisable(false);
checkBox.requestFocus();
}
@Override
public void cancelEdit() {
super.cancelEdit();
checkBox.setDisable(true);
}
public void commitEdit(Boolean value) {
super.commitEdit(value);
checkBox.setDisable(true);
}
@Override
public void updateItem(Boolean item, boolean empty) {
super.updateItem(item, empty);
if (!isEmpty()) {
checkBox.setSelected(item);
}
}
}
