Each object should be displayed consistently with the same widget, prompt, and general properties everywhere the user will encounter it. Specific exceptions are noted in this chapter.
In forms that are designed for high speed heads-down data entry, avoid any widget which cannot be operated from the keyboard and without looking at the screen. For example, a check box can be operated from the keyboard, but the user must look at the screen to see the current value because they cannot explicitly set it to checked or unchecked.
Items are always sequenced left-to-right, top-to-bottom, within a region, block, or window (OMS-71005).
For accessibility requirements, all functionality must be available from the keyboard.
The colors of objects are usually controlled automatically by the Oracle look and feel. Only in exceptional cases should these be overridden.
For more information on general properties of widgets, see the Oracle Applications Developer's Guide.
