Display items do not allow any user interaction - they merely display data and never accept cursor focus.
Use a display item for the following situations:
Null-canvas fields
Context fields
Fields that act as titles or prompts
If a field must accept cursor focus, either to allow scrolling or querying, it must be a text item, not a display item.

If an item is used to hold a dynamic title, use DYNAMIC_TITLE; if an item holds a prompt, use DYNAMIC_PROMPT. Both of these property classes provide a "canvas" colored background (gray). Otherwise, you should apply the DISPLAY_ITEM property class to your display items (provides a white background with no bevel).
To support bidirectional languages such as Arabic, do not use Left or Right justification. Use Start instead of Left, and generally use End in place of Right. Use Right only with numeric fields. You may use Center where appropriate.
Generally, applying the correct property class sets justification correctly.
Always make sure that the width (length) of the display item is large enough to accommodate translated values without truncating them. Items using either DYNAMIC_TITLE or DYNAMIC_PROMPT inherit a maximum length of 80 (which you should not change). Typically, the largest value you could accommodate in English would be about 60 characters (which, if expanded about 30 percent, fills an 80-character-wide field).
