Multiple FXML variables to 1 controller handle - email

Question

How can I make a handle that applies to each of the buttons, so I don't have to make a near-identical handle for each button?
So I have a FXML file with 9 contacts, each looks like this:
<Button fx:id="id1" mnemonicParsing="false" onAction="#handleContactEmailButtonAction" prefHeight="60.0" prefWidth="380.0" style="-fx-background-color: white;">
<graphic>
<VBox style="-fx-background-color: white; -fx-border-color: white;">
<children>
<Label prefHeight="30.0" prefWidth="334.0" text="Jane Doe" />
<Label prefHeight="17.0" prefWidth="349.0" text="jdoe#britishschool.sch.ae" textAlignment="CENTER" />
</children>
</VBox>
</graphic>
</Button>
And this is the controller:
#FXML
private Button id1;
#FXML
private Button id2;
#FXML
private Button id3;
#FXML
private Button id4;
#FXML
private Button id5;
#FXML
private Button id6;
#FXML
private Button id7;
#FXML
private Button id8;
#FXML
private Button id9;
#FXML
protected void handleContactEmailButtonAction(ActionEvent event) {
try {
Desktop desktop = Desktop.getDesktop();
String message = "mailto:"+emailvariable+"?subject=Music%20Bookings";
URI uri = URI.create(message);
desktop.mail(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
So if button with fx:id="id1" is clicked, then email variable changes to the email in the relevant label, and all with one controller?
Any and all help is appreciated, thank you!

Answer 1

Create a Map where you can get the button from event source like:
#FXML
private Button id1;
#FXML
private Button id2;
#FXML
private Button id3;
#FXML
private Button id4;
#FXML
private Button id5;
#FXML
private Button id6;
#FXML
private Button id7;
#FXML
private Button id8;
#FXML
private Button id9;
private Map<Button, String> emailVariables;
#Override
public void initialize(URL location, ResourceBundle resources)
{
emailVariables = new HashMap<Button, String>();
emailVariables.put(id1, "id1#example.com");
emailVariables.put(id2, "id2#example.com");
emailVariables.put(id3, "id3#example.com");
emailVariables.put(id4, "id4#example.com");
emailVariables.put(id5, "id5#example.com");
emailVariables.put(id6, "id6#example.com");
emailVariables.put(id7, "id7#example.com");
emailVariables.put(id8, "id8#example.com");
emailVariables.put(id9, "i91#example.com");
}
#FXML
protected void handleContactEmailButtonAction(ActionEvent event)
{
try
{
Desktop desktop = Desktop.getDesktop();
String message = "mailto:" + emailvariables.get((Button) event.getSource()) + "?subject=Music%20Bookings";
URI uri = URI.create(message);
desktop.mail(uri);
}
catch (Exception e)
{
e.printStackTrace();
}
}
Code is not tested.

Consider creating a custom component:
package application;
import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
public class EmailButton extends Button {
#FXML
private Label nameLabel ;
#FXML
private Label addressLabel ;
private final StringProperty name = new SimpleStringProperty();
private final StringProperty emailAddress = new SimpleStringProperty();
public EmailButton() throws IOException {
FXMLLoader loader = new FXMLLoader(getClass().getResource("emailButton.fxml"));
loader.setRoot(this);
loader.setController(this);
loader.load();
}
public void initialize() {
nameLabel.textProperty().bind(name);
addressLabel.textProperty().bind(emailAddress);
}
#FXML
private void sendEmail() {
try {
Desktop desktop = Desktop.getDesktop();
String message = "mailto:"+getEmailAddress()+"?subject=Music%20Bookings";
URI uri = URI.create(message);
desktop.mail(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
public StringProperty nameProperty() {
return name ;
}
public final String getName() {
return nameProperty().get();
}
public final void setName(String name) {
nameProperty().set(name);
}
public StringProperty emailAddressProperty() {
return emailAddress ;
}
public final String getEmailAddress() {
return emailAddressProperty().get();
}
public final void setEmailAddress(String emailAddress) {
emailAddressProperty().set(emailAddress);
}
}
and emailButton.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.VBox?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<fx:root xmlns:fx="http://javafx.com/fxml/1" type="Button" mnemonicParsing="false" onAction="#sendEmail" prefHeight="60.0" prefWidth="380.0" style="-fx-background-color: white;">
<graphic>
<VBox style="-fx-background-color: white; -fx-border-color: white;">
<children>
<Label fx:id="nameLabel" prefHeight="30.0" prefWidth="334.0" />
<Label fx:id="addressLabel" prefHeight="17.0" prefWidth="349.0" textAlignment="CENTER" />
</children>
</VBox>
</graphic>
</fx:root>
Now in your main FXML you can just do:
<?import application.EmailButton?>
<!-- ... -->
<EmailButton name="Jane Doe" emailAddress="jdoe#britishschool.sch.ae"/>
<EmailButton name="..." emailAddress="..." />
<EmailButton name="..." emailAddress="..."/>
etc
