Oracle Forms Developer – Form Builder Reference, Volume 1

item_name The name you gave the item when you created it. Datatype is
VARCHAR2.
property The property you want to set for the given item. Possible properties are:
Usage Notes
BORDER_BEVEL Specifies the item border bevel for the specified item
instance. Valid values are RAISED, LOWERED, PLAIN (unbeveled), or "
". A value of " " causes the border bevel to be determined by the value
specified at the item level at design-time or by SET_ITEM_PROPERTY at
runtime.
Note: You cannot set BORDER_BEVEL if the item’s Bevel property is set
to None in Form Builder.
INSERT_ALLOWED Applies only to records not retrieved from the
database. When set to PROPERTY_TRUE at the item instance, item, and
block levels, allows the end user to modify the item instance. Setting this
property to PROPERTY_FALSE at the item instance, item, or block levels,
prohibits the end user from modifying the item instance.
NAVIGABLE When set to PROPERTY_TRUE at the item instance and
item levels, allows the end user to be able to navigate to the item instance
using default keyboard navigation. Setting this property to
PROPERTY_FALSE at the item instance or item levels, disables default
keyboard navigation to the item instance.
REQUIRED Specify the constant PROPERTY_TRUE if you want to
force the end user to enter a non-null value for the item instance. Setting
this property to PROPERTY_FALSE at the item instance and item levels,
indicates that the item instance is not required.
UPDATE_ALLOWED Applies only to records retrieved from the
database. When set to PROPERTY_TRUE at the item instance, item, and
block levels, allows the end user to modify the item instance. When set to
PROPERTY_FALSE at the instance, item, or block levels, prohibits the
end user from modifying the item instance.
VISUAL_ATTRIBUTE Specify a valid named visual attribute that exists
in the current form or ’’. Specifying ’’ leaves visual attribute unspecified at
the item instance level.
When working with properties specified at multiple levels (item instance, item, and block), consider the
following guidelines:
• Required properties specified at multiple levels are ORed together
• Other boolean properties specified at multiple levels are ANDed together
The value derived from combining properties specified at the item instance, item, and block levels is
called the effective value. Some of the effects of these two rules are as follows:
• setting INSERT_ALLOWED to true has no effect at the item instance level unless it is set
consistently at the block and item levels. For example, your user cannot type data into an item
instance if INSERT_ALLOWED is true at the instance level, but not at the item or block levels.
• setting NAVIGABLE to true has no effect at the item instance level unless it is set consistently at
the item and item instance levels
