Since EASAP authors use the tools within EASA, all EASAPs will have similar Graphical User Interface (GUI) components, thus providing a consistent look and feel. The following sections will describe in more detail the common GUI components within EASAPs.

EASA features two different EASAP clients, the Web Browser Client and the EASA Client. The Web Browser Client is usually the preferred option due to the wider selection of features available.

EASAPs configured to run in the Web Browser Client offer a simplified user interface designed to run EASAPs in your existing web browser.

An example of the Web Browser Client is shown below.

The Web Browser Client features several function buttons to help manage the saving and submission of your EASAPs.

Icon	Name	Function
	Save EASAP	Saves current version of EASAP to Workspace. Always prompts for file name.
	Submit EASAP	Submits EASAP for EASA to run.
	EASAP Help	Opens the help pages for the EASAP in a separate browser window.
	Exit	Closes the Web Browser client window without saving.

The GUI components below the EASAP Toolbar will vary in terms of content from one EASAP to another. However, common components and characteristics are still present. The first common component to be explained is the TABBED PANE.

A Tabbed Pane represents one window pane’s worth of content on an EASAP. In a tabbed pane’s default configuration, it is denoted by a “tab” situated in a row just below the EASAP toolbar. This tab will contain a label describing the function and use of the TABBED PANE’s contents. In the default mode, you can move from one TABBED PANE to another simply by clicking on the tab of interest.

The two other modes in which tabbed panes can be displayed are:

1. Wizard mode
2. Tree mode

Wizard mode is characterized by the removal of the tabs and the inclusion of Next and Previous buttons at the bottom of the EASAP window for navigating from pane to pane. Tree mode is also characterized by the removal of the tabs, but instead of buttons for navigation, a hierarchical tree is displayed on the left side of the EASAP window, in which you display the pane of interest by clicking on it in the Tree.

The contents of a TABBED PANE can consist of one or the other or both of two types of regions below the row of tabs:

1. Input Region
2. Diagram Region

The Input Region contains all of the data entry boxes for a TABBED PANE. This area can also contain messages and tables that display results data and information. In this area, you will enter data through a variety of methods:

• Pull-down menus or choice lists

• Text input boxes

• Real and integer number input boxes

• Slider bars

• Check boxes

The number, layout and content of these data entry boxes will vary from EASAP to EASAP depending on the application.

Note: Both standard decimal notation e.g. 102.4, 0.024, etc. and exponential notation e.g. 1.024E+2, 2.4E-2, etc. are allowed when entering real numbers in real number input boxes.

In some cases, an EASAP will require that you specify and upload a particular type of file as input, such as a spreadsheet. The input box for a file upload will appear as shown below.

To upload a file, you first click on the Browse buttons located to the right of the input box, and then you locate and select your file. Finally, you click on the Upload button to upload your file.

When a diagram is present on a tabbed pane, it will appear in the Diagram Region to the left of the Input Region. In this area, EASAP authors can display a variety of images, graphs or diagrams. There are two fundamental reasons for the presence of diagrams in an EASAP:

1. Provide visual feedback to help you with input data entry
2. Display graphical output from results data generated by the EASAP

Examples of possible visual feedback mechanisms on data entry that you may encounter include:

• Shape change of image to reflect your dimensional input

• Line graphs that plot properties of items you have selected

• Appearance of text, shapes or dimension lines to highlight areas of concern Examples of possible graphical output of results that you may encounter include:

• Line graphs of results data

• Color contour plots of results data
