Hi,
Hope this helps..
1. In the Object Navigator, create a named visual attribute. To this..
1.1 Click on the Visual Attribute node, then click Create button on the toolbar(a button with + sign)
1.2 set the background color on the property pallete, you may change "named visual attribute" name property in descriptive manner.
2. Heres sample code...changes text item background when record updated, or when theres new record. Those text item only where the cursor is positioned will change.
DECLARE
it_id ITEM;
cur_rec NUMBER;
bk_id Block;
cur_blk VARCHAR2(40) := :System.Cursor_Block;
BEGIN
bk_id := Find_Block(cur_blk );
cur_rec := Get_Block_Property( bk_id, CURRENT_RECORD);
it_id := Find_Item('MACHINES.MACH_DESC');
IF :SYSTEM.RECORD_STATUS IN ('CHANGED','INSERT') THEN
COMMIT;
SET_ITEM_INSTANCE_PROPERTY (it_id,cur_rec,VISUAL_ATTRIBUTE,'UPDATE_INDICATOR');
NEXT_RECORD;
ELSE
NEXT_RECORD;
END IF;
END;
If you want to change the background of the whole text item if you display one or more text item in your form. Use set item_property....
SET_ITEM_PROPERTY
(item_id ITEM,
property NUMBER,
value VARCHAR2);
Parameters
item_id The unique ID that Form Builder assigned to the object when it created it. Use the FIND_ITEM built-in to return the ID to a variable with datatype of ITEM.
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:
AUTO_HINT Determines if Form Builder will display help hints on the status line automatically when input focus is in the specified item. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
AUTO_SKIP Specifies whether the cursor should skip to the next item automatically when the operator enters the last character in a text item. Valid only for a text item. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
BORDER_BEVEL Specifies the item border bevel for the specified item instance. Valid values are RAISED, LOWERED, or NONE.
CASE_INSENSITIVE_QUERY
Specifies whether query conditions entered in the item should be case-sensitive. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
CASE_RESTRICTION Specifies the case restriction applied to any text entered in the indicated text item. Valid values are UPPERCASE, LOWERCASE, or NONE.
COMPRESS[[Under Construction]]
CONCEAL_DATA Specify the constant PROPERTY_TRUE if you want the item to remain blank or otherwise obscured when the operator enters a value. Specify the constant PROPERTY_FALSE if you want any value that is typed into the text item to be visible.
CURRENT_RECORD_ATTRIBUTE
Specifies the VARCHAR2 name of a named visual attribute to be associated with the given item. If the named visual attribute does not exist, you will get an error message.
DIRECTION Specifies the layout direction for bidirectional objects. Valid values are DIRECTION_DEFAULT, RIGHT_TO_LEFT, LEFT_TO_RIGHT.
ECHO Specifies whether characters an operator types into a text item should be visible. When Echo is No, the characters typed are hidden. Used for password protection. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
ENABLED Specifies whether operators should be able to manipulate an item. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
Note: Setting Enabled to No will cause other item property settings to change. Consult the "Propagation of Property Changes" section for details.
FIXED_LENGTH Specifies whether the item's value should be validated against the setting of the item's Max Length property. When FIXED_LENGTH is True, the item is valid only if the number of characters in its value equals the Max Length setting. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
FORMAT_MASK Specifies the display format and input accepted for data in text items.
HEIGHT Specifies the height of the item.
ICON_NAME Specifies the file name of the icon resource associated with a button item having the iconic property set to ON.
IMAGE_DEPTH Specifies the depth of color to be applied to an image item.
INSERT_ALLOWED In a new record, allows operator to insert items normally when set to PROPERTY_TRUE. Specify PROPERTY_FALSE to specify that the item does not accept modification, but is displayed normally (not grayed out). (Insert_Allowed does not propagate changes to the Enabled property.)
ITEM_IS_VALID Specifies whether the current item should be considered valid. Set to PROPERTY_TRUE or PROPERTY_FALSE.
ITEM_SIZE Specifies a width and height for the item as two numbers separated by a comma. Use the syntax that includes x, y.
JUSTIFICATION The text alignment (text and display items only). Valid values are ALIGNMENT_START, ALIGNMENT_END, ALIGNMENT_LEFT, ALIGNMENT_ CENTER, ALIGNMENT_RIGHT.
KEEP_POSITION Specifies whether the Keep Cursor Position property should be Yes or No. When Keep Cursor Position is Yes, the cursor returns to the same position it was in when it left the text item. When Keep Cursor Position is No, the cursor returns to the default position in the text item. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.
LABEL Specifies the VARCHAR2 string that you want displayed as the label of the item. This property is only valid for items that have labels, such as buttons.
LOCK_RECORD_ON_CHANGE
Specify the constant PROPERTY_TRUE if you want the record to be locked when this item is changed. Specify the constant PROPERTY_FALSE if you do not want the record locked when this item is changed. Use primarily when connecting to a non-ORACLE data source that does not have row-level locking.
LOV_NAME Specify the VARCHAR2 name of an LOV to be associated with the given item. If the LOV name does not exist, you will get an error message.
MOUSE_NAVIGATE Specifies whether Form Builder should navigate and set focus to the item when the operator activates the item with the mouse. Specify the constant PROPERTY_TRUE if you want the operator to be able to navigate to the item using the mouse. Specify the constant PROPERTY_FALSE if you want a mouse click to keep the input focus in the current item.
NAVIGABLE Specify the constant PROPERTY_TRUE if you want the operator to be able to navigate to the item using default keyboard navigation.

VALIDATE_FROM_LIST Specifies that Form Builder should validate the value of the text item against the values in the attached LOV when set to PROPERTY_TRUE. Specify PROPERTY_FALSE to specify that Form Builder should not use the LOV for validation.
VISIBLE Specifies whether the indicated item should be visible or hidden. Valid values are PROPERTY_TRUE and PROPERTY_FALSE.

VISUAL_ATTRIBUTE Specify a valid named visual attribute that exists in the current form.
Note: You cannot set the visual attribute for an image item.
