JavaFX labels height

I'm developing software in JavaFX and JavaFX Scene Builder.

I have a grid pane with 2 columns. Actually in each of the cells there are labels. In the first column of the table the text inside the label is a default constant, in the second one the text can change.

The problem is that if the text variable is too long, it's automatically truncated.

How to start a new line trimming the text and re-sizing the height of the rows in the grid pane?

EDIT:

Thanks to @fabian issues, this is the solution to the initial question. In addiction is necessary to set the fx:id of each element into Scene Builder.

@FXML private GridPane gridPane;
@FXML private Text text1;
@FXML private Text text2;
@FXML private Text text3;


private void setGridRowHeight(GridPane gpName, int numRow, double height){
    ObservableList<RowConstraints>  rows = gpName.getRowConstraints();
    rows.get(numRow).setMinHeight(32);
    rows.get(numRow).setPrefHeight(height);
    rows.get(numRow).setMaxHeight(height);
}


private void addTextListener(final GridPane gridPane, final Text text){

    text.textProperty().addListener(new ChangeListener<String>() {
        @Override
        public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
            scrollPane.setFitToHeight(true);
            text.setWrappingWidth( gridPane.getColumnConstraints().get(1).getPrefWidth() );
            setGridRowHeight(gridPane, gridPane.getRowIndex(text), text.getLayoutBounds().getHeight() );
        }
    });
}


@FXML public void initialize() {
    addTextListener(gridPane, text1);
    addTextListener(gridPane, text2);
    addTextListener(gridPane, text3);
}

Unfortunately the Label element does not resize depending on the text displayed. I recommend using the Text Shape. You can specify the maximal width using wrapping width in the scene builder.

You could try:

Label col2Label = new Label();
col2Label.setWrapText( true );
col2Label.setMaxHeight( Double.MAX_VALUE );
col_1_Label.prefHeightProperty().bind( col2Label.heightProperty() );

You can wrap [Region - Label - Region] in HBox. The region will keep the label always centered.
