Oracle form 程式碼控制控制元件屬性函式大全
需求：實現tab頁的實時隱藏和顯示
實現：SET_TAB_PAGE_PROPERTY('MAIN_TAB.RETS_PAGE',VISIBLE,property_off);/SET_TAB_PAGE_PROPERTY('MAIN_TAB.RETS_PAGE',VISIBLE,property_on); 以下為轉載內容，Oracle提供了各種程式碼設定屬性的函式，引數可以到form builder的聯機幫助裡面查詢，原部落格地址：http://blog.csdn.net/pan_tian/article/details/8434666Build-In List

set_item_property('<block_name>.<list_item_name>',VISIBLE/UPDATEABLE,PROPERTY_TRUE);
else
set_item_property('<block_name>.<list_item_name>',VISIBLE/UPDATEABLE,PROPERTY_FALSE);
end if;
end;
or
app_item_property.set_property ('<block_name>.<list_item_name>', enabled/enterable, property_on);
set_block_property
set_block_property ('<block_name>', query_allowed/update_allowed/delete_allowed, property_true);
SET_LOV_PROPERTY
SET_LOV_PROPERTY('inv_serial_lov', GROUP_NAME, 'inv_serial18');
Set_Record_Property
/*
** Built-in: SET_RECORD_PROPERTY
** Example: Mark the third record in the EMP block as if it
** were a queried record.
*/
BEGIN
Set_Record_Property( 3, ’EMP’, STATUS, QUERY_STATUS);
END;

Difference Between Set_Item_Instance_Property and Set_Item_Property
SET_ITEM_PROPERTY：Block中的所有Records
SET_ITEM_INSTANCE_PROPERTY:對當前Record起作用
If you want to turn fields 'on' and 'off' depending on information in a row then use 'set_item_instance_property(enterable)' in the Post_Query trigger on the block
IF :BLK_DISPLAY.METER_TYPE_ID = 'H' THEN
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.MILES',CURRENT_RECORD,VISUAL_ATTRIBUTE,'VA_DISPLAY_ONLY');
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.MILES',CURRENT_RECORD,NAVIGABLE,PROPERTY_FALSE);
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.MILES',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_FALSE);
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.HOURS',CURRENT_RECORD,VISUAL_ATTRIBUTE,'VA_UPDATE');
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.HOURS',CURRENT_RECORD,NAVIGABLE,PROPERTY_TRUE);
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.HOURS',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_TRUE);
ELSIF :BLK_DISPLAY.METER_TYPE_ID = 'M' THEN
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.MILES',CURRENT_RECORD,VISUAL_ATTRIBUTE,'VA_UPDATE');
SET_ITEM_INSTANCE_PROPERTY('BLK_DISPLAY.MILES',CURRENT_RECORD,NAVIGABLE,PROPERTY_TRUE);
