[Form Builder]APP_ITEM_PROPERTY.SET_PROPERTY 用法

ORACLE 推荐使用此种方法来控制ITEM属性，虽然实质也是调用set_item_instance_property和set_item_property

ALTERABLE

app_item_property.set_property(itemid, ALTERABLE,PROPERTY_ON);

is equivalent to:

set_item_instance_property(itemid, CURRENT_RECORD,INSERT_ALLOWED, PROPERTY_ON); set_item_instance_property(itemid, CURRENT_RECORD,UPDATEABLE, PROPERTY_ON);

set_item_property(itemid, INSERT_ALLOWED, PROPERTY_ON);

set_item_property(itemid, UPDATEABLE, PROPERTY_ON);

ALTERABLE_PLUS

app_item_property.set_property(itemid, ALTERABLE_PLUS,PROPERTY_ON);

is equivalent to:

set_item_property(itemid, INSERT_ALLOWED, PROPERTY_ON);

set_item_property(itemid, UPDATEABLE, PROPERTY_ON);

If the item is currently hidden, no action is taken.

ENTERABLE

app_item_property.set_property(itemid, ENTERABLE,PROPERTY_ON);

is equivalent to:

set_item_instance_property(itemid, CURRENT_RECORD,INSERT_ALLOWED, PROPERTY_ON); set_item_instance_property(itemid, CURRENT_RECORD,UPDATEABLE, PROPERTY_ON);

set_item_instance_property(itemid, CURRENT_RECORD,NAVIGABLE, PROPERTY_ON);

set_item_property(itemid, INSERT_ALLOWED, PROPERTY_ON);

set_item_property(itemid, UPDATEABLE, PROPERTY_ON);

set_item_property(itemid, NAVIGABLE, PROPERTY_ON);

If the item is currently hidden, no action is taken.

ENABLED

app_item_property.set_property(itemid, ENABLED,PROPERTY_ON);

is equivalent to (for a text item or a list item):

set_item_property(itemid, INSERT_ALLOWED, PROPERTY_ON);

set_item_property(itemid, UPDATEABLE, PROPERTY_ON);

set_item_property(itemid, NAVIGABLE, PROPERTY_ON);

If the item is a button, then the APP_ITEM_PROPERTY.SET_PROPERTY call is equivalent to:

set_item_property(itemid, ENABLED, PROPERTY_ON);

If the item is not a text item, list, or button, then the APP_ITEM_PROPERTY.SET_PROPERTY call is equivalent to: set_item_property(itemid, ENABLED, PROPERTY_ON);

set_item_property(itemid, INSERT_ALLOWED, PROPERTY_ON);

set_item_property(itemid, UPDATEABLE, PROPERTY_ON);

DISPLAYED

app_item_property.set_property(itemid, DISPLAYED,PROPERTY_ON);

is equivalent to:

set_item_property(itemid, DISPLAYED, PROPERTY_ON);

If the item is not a display item then also set:

set_item_property(itemid, ENABLED, PROPERTY_ON);

set_item_property(itemid, NAVIGABLE, PROPERTY_ON);

If the item is neither a display item nor a button then also set:

set_item_property(itemid, QUERYABLE, PROPERTY_ON);

set_item_property(itemid, INSERT_ALLOWED, PROPERTY_ON);

set_item_property(itemid, UPDATEABLE, PROPERTY_ON);

REQUIRED

app_item_property.set_property(itemid, REQUIRED,PROPERTY_ON);

is equivalent to:

set_item_property(itemid, REQUIRED, PROPERTY_ON);

If the item is currently hidden, no action is taken.
