JavaFX 2: Create Login Form

In this tutorial I will design a nice looking Login Form with JavaFX 2 and CSS. It’s clasic login form with username and password, and login button. In order to follow this tutorial I strongly recommend you to check these tutorials below:

Username: JavaFX2 Password: password

You can enter this information above and click on Login button. It will tell you with a little message that login is successful, but if you enter wrong information, it will tell you with a little message that login isn’t successful.
The final output screenshot of this tutorial will be like below image.

        //Adding HBox
        HBox hb = new HBox();
        hb.setPadding(new Insets(20,20,20,30));
        
        //Adding GridPane
        GridPane gridPane = new GridPane();

        final TextField txtUserName = new TextField();
        Label lblPassword = new Label("Password");
        final PasswordField pf = new PasswordField();
        Button btnLogin = new Button("Login");

        //Adding Nodes to GridPane layout
        gridPane.add(lblUserName, 0, 0);
        gridPane.add(txtUserName, 1, 0);

        gridPane.add(pf, 1, 1);
        gridPane.add(btnLogin, 2, 1);
        gridPane.add(lblMessage, 1, 2);
        
                
        //Reflection for gridPane
        Reflection r = new Reflection();
        r.setFraction(0.7f);
        gridPane.setEffect(r);
        
        //DropShadow effect 
        DropShadow dropShadow = new DropShadow();
        dropShadow.setOffsetX(5);
        dropShadow.setOffsetY(5);
        
        //Adding text and DropShadow effect to it
        Text text = new Text("JavaFX 2 Login");
        text.setFont(Font.font("Courier New", FontWeight.BOLD, 28));
        text.setEffect(dropShadow);
        
        //Adding text to HBox
        hb.getChildren().add(text);
                          
        //Add ID's to Nodes
        bp.setId("bp");
        gridPane.setId("root");
        btnLogin.setId("btnLogin");
        text.setId("text");
                
        //Action for btnLogin
        btnLogin.setOnAction(new EventHandler() {
         public void handle(ActionEvent event) {
          checkUser = txtUserName.getText().toString();
          checkPw = pf.getText().toString();
          if(checkUser.equals(user) && checkPw.equals(pw)){
           lblMessage.setText("Congratulations!");
           lblMessage.setTextFill(Color.GREEN);
          }
          else{
           lblMessage.setText("Incorrect user or pw.");
           lblMessage.setTextFill(Color.RED);
          }
          txtUserName.setText("");
          pf.setText("");
         }
         });
       
        //Add HBox and GridPane layout to BorderPane Layout
        bp.setTop(hb);
        bp.setCenter(gridPane);  
        
        //Adding BorderPane to the scene and loading CSS
     Scene scene = new Scene(bp);
     scene.getStylesheets().add(getClass().getClassLoader().getResource("login.css").toExternalForm());
     primaryStage.setScene(scene);
       primaryStage.titleProperty().bind(
                 scene.widthProperty().asString().
                 concat(" : ").
                 concat(scene.heightProperty().asString()));
     //primaryStage.setResizable(false);
     primaryStage.show();
    }
}

In order to style this application properly you’ll need to create login.css file in /src folder of your project. If you dont know how to do that, please check out JavaFX 2: Styling Buttons tutorial.

Here is CSS code of our example:

#root {
 -fx-background-color:  linear-gradient(lightgray, gray);
 -fx-border-color: white;
 -fx-border-radius: 20;
 -fx-padding: 10 10 10 10;
 -fx-background-radius: 20;
 
}

#bp {
 -fx-background-color:  linear-gradient(gray,DimGrey );
 
}

#btnLogin {
    -fx-background-radius: 30, 30, 29, 28;
    -fx-padding: 3px 10px 3px 10px;
    -fx-background-color: linear-gradient(orange, orangered );
}

#text {
 -fx-fill:  linear-gradient(orange , orangered);
}
