JavaFX Create Email Form 

This is a practical tutorial in which we see how to create a beautiful email sending form using the following controls:

  1. ComboBox – Custom editable and non-editable comboboxes.
  2. TextField – To display the email subject.
  3. Labels – To show various captions and notification when email is sent.
  4. TextArea – To allow user to type the email message.
  5. Button – To simulate sending email when clicked.

Let’s start.
