Menu that appears on the screen at thelocation it was invoked• Enables users to

access commonly used functions easily

such as alerts or Data Blocks – Built through the Property Palette or

Menu Editor– Associated with items and canvases

with a pop-up menu property

• Pre-Popup-Menu trigger providesdynamic control


Writing PL/SQL Code in Menu Triggers

• Similar to PL/SQL code in form triggers• You can share code between a form

module and a menu module by using the following:– Libraries– User-defined triggers– DO_KEY built-in


Writing PL/SQL Code in Menu Triggers

• Menu modules generated independently• Restrictions:

– Cannot directly reference values of form objects

– Must use NAME_IN built-in function– Cannot use direct assignment for

form objects– Must use COPY built-in procedure


Built-ins Used

• FIND_MENU_ITEM• GET_MENU_ITEM_PROPERTY• SET_MENU_ITEM_PROPERTY• ITEM_ENABLED• MENU_SHOW_KEYS
