JavaFx Label - how to force a new line (line break)

Question

I am trying to write to a JavaFX label. I can write successfully and use wrapping to make sure the text wraps to a new line if it is longer than the label. My issue is I need to add text to the existing text which I can do, but I am unable to make the next text start on a new line.

Any help would be appreciated.

Solution 1

Just add a newline character:

Label label = new Label();
label.setText("Hello\nWorld");

Solution 2

I have been looking for multiline label trick in FXML for some time and many times I visited this post (google displayed this result, a lot of frustration). So I think I will write it here.

I managed to find this code to display multiline:

<Label text="${'number of registered\nreaders'}"/>

But if I define variable

<fx:define>
    <String fx:id="LABEL_01" fx:value="${'number of registered\nreaders'}"/> 
</fx:define>

then I have no idea how to refer to it, I can't use $LABEL_01.

In FXML you can also use this: '
'. Then this code works:

<fx:define>
    <String fx:id="LABEL_01" fx:value="number of registered&#xD;readers"/> 
</fx:define>

And you can use LABEL_01 like this:

<Label text="$LABEL_01"/>
