BorderPane in JavaFX - Guide to GUI Development

The layout management in JavaFX is crucial for designing appealing and functional user interfaces. One of the most versatile layouts you can use in your JavaFX application is BorderPane. In this guide, I want to show you how to effectively design a user interface with BorderPane that is easy to use and well-structured. We assume that you are developing an application that resembles an email client application, so let’s get started.

Key Insights

• The BorderPane layout consists of five main areas: top, bottom, left, right, and center.
• Each area can contain different layouts and controls.
• BorderPane allows for a logical and appealing structure of the user interface.

Step-by-Step Guide

Step 1: Creating the BorderPane

To get started with our BorderPane, you first need to instantiate this layout and insert it into your scene. The following code shows how to create a new BorderPane with dimensions of 500x600, for example.

Step 2: Adding Controls

Now let’s turn to the individual areas. We will start with the top area, where we will place a label that serves as a title. You can easily create your label as follows:

Step 3: Creating VBox for the Sides

For the left and right sides of the BorderPane, we will use VBox layouts. This allows us to arrange the contained elements vertically.

Step 4: Arranging Controls in the Left VBox

Now we will add some buttons to the left VBox to represent the emails. For example, one button could represent the text "Email 1".

Step 5: Displaying Emails in the Center

For the central area, we will add an HTMLEditor that allows the user to write or view emails. Here’s how to create an HTMLEditor:

Step 6: Adding Details in the Bottom Area

In the bottom area of the BorderPane, you could place a TextArea to display HTML content.

Step 7: Using the Right Area

We will add another button in the right VBox to display the HTML created in the editor.

Step 8: Implementing Logic for the Button

Finally, we need to ensure that the button actually displays the HTML content. To do this, we will add an action event handler:

Step 9: Completion and View

Now it’s time to bring everything together and display our BorderPane in the application. If you have implemented everything correctly, your user interface should now be structured as desired.
