1. Introduction

This document is the user experience specification for the JavaFX HTML Text Editor control.

2. Overview

HTML Text Editor (aka WYSIWYG Editor) is a UI control that provides users with an editing interface which allows them to see the content how it will be displayed in a web browser.

HTML Text Editor control serves for three purposes::

1. creating/editing a web page (e.g. Wiki),
2. commenting an article/blog post, and
3. sending/displaying formatted text in an email or chat client.

In these days, there are a lot of various WYSIWYG Editors available on the Internet. Based on our research, we have identified a set of basic features and their actions that the HTML Text Editor control should provide. These are as follows:

1. Fundamental Features - this includes basic actions such as Cut, Copy, and Paste. In addition to these, users are also allowed to Undo and Redo changes.
2. Styling - allows users to define Font Family, Font Size, Style (Paragraph, Heading 1, 2, ...), and Character Style (Bold, Italic, Underline, Strikethrough). It also allows users to define Text Alignment (Left, Center, Right, Justify), Indent and Outdent,Bulleted and Numbered Lists, and insert a Horizontal Rule.
3. Colors - allows users to specify Text Color and Background Color.
4. Linking - allows users to easily Insert Hyperlink and Remove Hyperlink (Unlink).

Next generation of HTML Text Editor control should provide users with more advanced features/actions such as:

1. Advanced Styling - allows users to display text as Superscript or Subscript, and Clear Styles.
2. Inserting Rich Content - allows users to Insert File, Insert Video, Insert Picture, Insert Table, Insert Special Character, andInsert Form Controls.
3. Additional Features - includes features such as Find and Find and Replace. In addition to these, it also includes Print,Maximize/Fullscreen, Show HTML Source, and Insert Anchor.

3. Interaction Design

This section describes actions that are mentioned in Basic Features set in more details. Please note that each action is represented in the HTML Text Editor's Toolbar as an icon. Hovering over each icon will show the associated tooltip.

The following picture shows a wireframe of HTML Text Editor Control.
