DISPLAY ARRAY ATTRIBUTES clause
Attributes of the DISPLAY ARRAY clause of a DIALOG block.
HELP option
The HELP
attribute
defines the number of the help
message to be displayed when invoked and focus is in the
list controlled by the DISPLAY ARRAY
sub-dialog.
The predefined 'help' action is automatically created by the runtime
system. You can bind action
views to the 'help' action.
The HELP
clause overrides the HELP
attribute.
COUNT option
The COUNT
attribute
defines the number of valid rows in the static array to be displayed as
default rows. If you do not use the COUNT
attribute,
the runtime system cannot determine how much data to display,
so the screen array remains empty. The COUNT
option
is ignored when using a dynamic array, unless page mode is used.
In this case, the COUNT
attribute must be used
to define the total number of rows, because the dynamic array will
only hold a page of the entire row set. If the value of COUNT
is
negative or zero, it defines an empty list.
See also Controlling the number of rows.
DOUBLECLICK option
The DOUBLECLICK
option can be used to define the action that will
be fired when the user chooses a row from the list. Different configuration options are available to
control the row selection action of desktop and mobile devices. For more details, see Defining the action for a row choice.
ACCESSORYTYPE option
The ACCESSORYTYPE
attribute can be used to define the decoration of
rows, typically used on an iOS device. Values can be DETAILBUTTON
,
DISCLOSUREINDICATOR
, CHECKMARK
to respectively get a
(i)
, >
or check mark icon. For more details, see Row configuration on iOS devices.
DETAILACTION option
The DETAILACTION
attribute can be used to define the action that
will be fired when the user selects the detail button of a row. The detail button is
typically shown with a (i)
icon on iOS devices. Note that the
DOUBLECLICK
attribute can be used to distinguish the action
when the user selects the row instead of the detail button in the row. For more
details, see Row configuration on iOS devices.
FOCUSONFIELD option
When the FOCUSONFIELD
option is used, the DISPLAY
ARRAY
allows focus at the field (or cell) level. It it then possible to implement
BEFORE FIELD
and AFTER FIELD
blocks, as well as using NEXT
FIELD
instructions. However, the dialog still manages a read-only list. For more details,
see Field-level focus in DISPLAY ARRAY.
