JavaFX TableView custom cell rendering split menu button

Question

i\'ve a problem with a custom cell render in a java fx table view component. I\'m able to render the split menu button, but is only rendered from second row of table.

Answer 1

Cause you have use the same button in every cell, So it's set a button only last of the cell Value.

Remove this line in SplitMenuButtonApp class

 SplitMenuButton actions = sMBtn.buildButton();

And replace this line

aCol.setCellFactory(new ButtonCellFactory<>(actions));

To below code

Callback<TableColumn<Contact, SplitMenuButton>, TableCell<Contact, SplitMenuButton>> actionsCol = new Callback<TableColumn<Contact, SplitMenuButton>, TableCell<Contact, SplitMenuButton>>() {
                @Override
                public TableCell call(final TableColumn<Contact, SplitMenuButton> param) {
                    final TableCell<Contact, SplitMenuButton> cell = new TableCell<Contact, SplitMenuButton>() {
                        SplitMenuButton actions = sMBtn.buildButton();
                        @Override
                        public void updateItem(SplitMenuButton item, boolean empty) {
                            super.updateItem(item, empty);
                            if (empty) {
                                setGraphic(null);
                                setText(null);
                            } else {
                                setGraphic(actions);
                                setText(null);
                            }
                        }
                    };
                    return cell;
            }
 };

aCol.setCellFactory(actionsCol);

I hope this code is working for you:)
