Image Field Tab Order Options
Tab Level defines the physical pass over the whole screen with respect to tab order. If left blank, the data object is considered to be in tab level 0. APPX will tab from top-left to bottom-right for all data objects in tab level 0. Then it repeats the sequence for all button objects in tab level 0. The cycle is repeated as necessary for each successive tab level. This behavior can be altered by the specification of Tab Groups.
Tab Group is used to mark related data objects and buttons so that they are grouped together as part of a tab order. When making a pass over the screen for a particular "Tab Level", if a data object is encountered that has a non-null "Tab Group", then the tab order proceeds to all the data objects and buttons that are part of that Tab Level/Tap Group. After reaching the last data object or button in the group, the order will continue where it left off prior to encountering the group. Note that for "Tab Groups", data objects and buttons are consolidated into the same top-left to bottom-right pass.
