I have Label on my fxml file:
<children>
<Label fx:id="lblTest" text="Label" />
</children>
How can i change the text from "Label" to "Hello" from the main/controller java file?
I just started to learn the basics of JavaFX and i am not sure if it possible
You want to set the text on a label that is part of FXML/Controller/MainApp
Normally you have three files:
A little Example:
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class LabelText extends Application {
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.40" fx:controller="labeltext.FXMLDocumentController">
<children>
<Label fx:id="lblTest" layoutX="126.0" layoutY="92.0" minHeight="16" minWidth="69" />
</children>
</AnchorPane>
package labeltext;
import javafx.fxml.FXML;
import javafx.scene.control.Label;
public class FXMLDocumentController {
@FXML
private Label lblTest;
@FXML
private void initialize() {
lblTest.setText("I'm a Label.");
}
}
And that's it.
