    The EGL Programmer's Guide covers using EGL within the Eclipse Integrated Development Environment (IDE), as well as some of the common programming tasks that EGL developers perform.
    - Introduction
      These topics explain the fundamentals of using EGL in the Eclipse IDE, as well as changes to the EGL language and IDE in this version.
    - Contents of an EGL application
      EGL applications contain projects, packages, folders, and files.
    - Properties
      Properties set specific options for parts. In general, you specify the properties when you create the part and then the properties are static. In certain circumstances, however, it is possible to change a property dynamically.
    - Annotating EGL Applications
      EGL developers can annotate their applications to indicate the version, authors as well as a general description.
    - Import and use statements
      Use the EGL import and use statements to expand the visibility of code elements.

      - Common programming tasks
        These topics contain information on how to complete several common programming tasks in EGL.
      - The EGL editor
        The EGL code editor looks and works like a standard text editor or code editor for other languages, but it has additional features to help you edit EGL code. The code editor highlights invalid syntax, provides an explanation for problems in the code, colors keywords, strings, and comments, and helps you write EGL code.
      - Content assist
      - Using cheat sheets
        Cheat sheets can assist you with common tasks in the Workbench. They provide step-by-step instructions within a workbench view and can perform some of the steps in the task automatically.
      - Editing DataItem parts with the source assistant
      - Searching for EGL files and parts
        The workbench provides several options for searching for and viewing EGL files and parts.
        Searching for parts

        Viewing lists of parts
        You can choose one or more EGL parts and group those parts in a list to filter or sort them.
        Viewing part references
        The EGL Parts Reference view lists, in a tree format, the data declarations and functions that are in a main part. A primary use of the view is to navigate quickly to a part that is the basis of a data declaration.

- Responsive Design Support in IBD
  What is Responsive Design? Responsive design is an approach for creation of web pages that automatically scales its content and elements to match the screen size on which it is viewed. So, instead of designing multiple websites for different devices with variable screen sizes, we can design just one website that scales up or down automatically, to match the device it’s being viewed on.

Searching for parts

You can search for parts among the EGL projects in your workspace.

This search returns part definitions and references; it does not search your project for a text match to a string. For a textual search of your project, click Search > File.

To search for a list of available parts, follow these steps:

From the main menu, click Search > EGL. The Search window opens to the EGL Search tab.
If you do not see Search > EGL, click Search > Search and switch to the EGL Search tab.
Type the criteria for the search in the Search string field. You can use the following wildcard symbols in your search:
- A question mark (?) represents any one character
- An asterisk (*) represents a series of any characters of any length
For example, type my?Part to locate parts named "my1Part" and "my2Part", but not "my10Part". Type my*Part to locate parts named "my1Part", "my2Part", and "my10Part".
Click the Case sensitive check box for a case-sensitive search.
In the Search For section, select the type of part you are searching for, or select Any element to expand your search to all part types.
In the Limit To section, select the option to limit your search to part declarations, part references, or any occurrence of the search string.
In the Scope section, select where to search:
Workspace
Searches the current workspace.
Selected resources

Searches the resources currently selected in the Project Explorer view or other view.
Enclosing projects
Searches the project or projects that contain the files selected in the Project Explorer view or other view.
Working set
Searches a set of projects, called a working set. Click Choose to select the working sets to search.
Click Search. The results are displayed in the Search view.
If you double-click a file in the Search view, the file opens in the EGL editor, and the matching part is highlighted. If there is more than one match in the file, the first match is highlighted.
Arrows in the left margin of the editor indicate the locations of each matching part.
