- Introduction Overview By default, each form module uses the same menu structure, call the Default menu, This lesson teaches you how to customize this menu and how to create your own menu Modules. You will also learn how to enhance your application b including menu toolbars and pop-up menus.
- Components of the Menu Module What is a Menu Module? A menu module is a hierarchically structured object that provides a quick and easy Method for operating you Forms application. Like the form module menu module Is one of the main components of an application. Each menu module displays as a pull-down menu. A pull-down menu comprises a set Of options, displayed horizontally under the application window title. Each option can Represent a submenu or an action. Selecting a submenu displays a vertical list. Selecting an action executes the action.
- What is the Default Menu? The Default menu is not a separate menu module and is built in to every form module. A custom menu is stored in a separate module that has a suffix of .mmb. A custom menu that is Exactly the same as the default menu, menudef.mmb, ships with Oracle Developer Forms.
- Technical Note By default, the Menu Editor displays a pull-down menu, with the top-level menu displayed Horizontally. If you are developing a full-screen menu, you may want to display the top-level Menu vertically, so that the display matches the way your menu will appear at run time. To Change the orientation, click the Switch Orientation button.
- Technical Note Radio menu items must belong to a radio group. All of the radio items for a radio group must be Contiguous on the same menu. Radio group names are internal names that are not displayed at Runtime.
- Note: The command types of Form, Plus and Macro are available for backward compatibility only. Web Design Tip If you invoke the HOST command with web-deployed forms, the required process will run on the Forms Services machine, not on the client. The client will not be able to view or participate in that Process.
- Technical Note If you want to use the Default menu without the associated menu toolbar, replace the Value DEFAULT&SMARTBAR in the Menu Module property with DEFAULT only.
- Technical Note REPLACE_MENU replaces the menu for all windows in the application. If You are using CALL_FORM, REPLACE_MENU replaces the menu for Both the calling form and the called form with the specified menu.
- Technical Note If Use Security is modified by must recompile the menu module.
