Using custom javafx label doesn't work - javafx

Question

Ok so I've created my own customer label, for this example it's extremely basic. What I did was extend the Javafx Label in my custom class called MyLabel. I'm also using FXML to create the GUI. Now when I do this I can't seem to instantiate with my custom class as I get this error.
"Can not set net.blacksquirreldevs.tests.MyLabel field net.blacksquirreldevs.tests.SampleLabelController.sampleLabel to javafx.scene.control.Label"
Here is the code for everything
Main.java
package net.blacksquirreldevs.tests;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("SampleLabel");
AnchorPane anchorPane = (AnchorPane) FXMLLoader.load(getClass().getResource("SampleLabel.fxml"));
primaryStage.setScene(new Scene(anchorPane));
primaryStage.show();
}
public static void main(String... args) {
launch(args);
}
}
MyLabel.java
package net.blacksquirreldevs.tests;
import javafx.scene.control.Label;
public class MyLabel extends Label {
public MyLabel(String text) {
super();
setText(text);
}
}
SampleLabelController.java
package net.blacksquirreldevs.tests;
import javafx.fxml.FXML;
import java.net.URL;
import java.util.ResourceBundle;
public class SampleLabelController {
#FXML
private ResourceBundle resources;
#FXML
private URL location;
#FXML
private MyLabel sampleLabel = new MyLabel("Hello world!");
#FXML
void initialize() {
assert sampleLabel != null : "fx:id=\"sampleLabel\" was not injected: check your FXML file 'SampleLabel.fxml'.";
}
}
And finally the fxml file SampleLabel.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>
<?import javafx.scene.text.*?>
<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" fx:controller="net.blacksquirreldevs.tests.SampleLabelController">
<children>
<Label fx:id="sampleLabel" layoutX="153.0" layoutY="171.0" text="Sample Text">
<font>
<Font name="Arial Bold" size="50.0" />
</font>
</Label>
</children>
</AnchorPane>
So what I want to know is why I can' declare, in my SamplelabelController class, the sampleLabel as MyLabel?
Hopefully I've explained this well enough, if not let me know and I'll try to go a bit more in detail.

Answer 1

You are using <Label ... in your FXML instead of <MyLabel
Beside that your MyLabel has a none default constructor and in this case you NEED to provide a builder named MyLabelBuilder so that FXMLLoader can create an instance of MyLabel
