Chapter 1-1: Overview of Application Design
Named Resources
The named resources option is used to define a resource name for referencing a group of related graphic files within the application. Once a named resource has been defined, any references to the named resource on a GUI Attribute screen will result in the bitmap for the appropriate state being displayed on the image or object. This feature is used when designing GUI images that include buttons, icons and pictures. The type of image file being used varies based on where the graphical attributes are being defined. Typically, a resource is used in this manner:
| Defined At | Graphic File Normally Contains |
| Frame | Title bar icon, wallpaper bitmap |
| Image | Title bar icon, wallpaper bitmap |
| Child | Menu icon (pull-down, toolbar, pop-up) |
| Button | Button icon for one or more states (enabled, disabled, pressed, rollover, etc.) |
| Picture | Picture or image file |
When you select the named resources option from the Application Design Specifications Menu, the Named Resources screen is displayed, as shown in Figure 1-1-9 below.
Named Resources screen
The Named Resources screen is a scrolling display which contains the following fields:
- Resource Name for assigning a name to a related group of bitmaps
- Description to further define the Resource Name
Select detail to further define the selected resource. The detail display shown in Figure 1-1-10 allows you to define the “states” for this resource.
