JavaFx: Label text width

Question

I have a problem with the Label's width. If I change the size of the window and the label's width doesn't fit to the window.

I expect something like:

Initial: 012345678901234567890123456789

After resize: 01234567890123...

But the actual state:

Initial state

After resize:

After resize

How can I get my expected result?

Here is the .fxml file

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.HBox?>
<AnchorPane xmlns="http://javafx.com/javafx"
 xmlns:fx="http://javafx.com/fxml"
 fx:controller="stackoverflow.labeltest.Controller">
 <HBox>
 <Label fx:id="label"/>
 </HBox>
</AnchorPane>

• Itai: The HBox is probably still the same size, as AnchorPane doesn't resize its children (I think). Try removing the AnchorPane, having the HBox as the root.

Answer 1

An AnchorPane does not resize a child without constraints. You need to set the rightAnchor and leftAnchor constraints of the HBox. (You could also simply use the HBox as root.)

<AnchorPane xmlns="http://javafx.com/javafx"
 xmlns:fx="http://javafx.com/fxml"
 fx:controller="stackoverflow.labeltest.Controller">
 <children>
 <HBox AnchorPane.rightAnchor="0" AnchorPane.leftAnchor="0">
 <children>
 <Label fx:id="label"/>
 </children>
 </HBox>
 </children>
</AnchorPane>

• Sunflame: Yes you are right I am using simply the HBox as root and it works :) Thanks.
