Menu Types and Rules

Forms may have a bar menu gadget or main menu, which appears as a row of options across the top of the form. When you select one of the menu options, a pull-down menu is temporarily displayed. Fields on a menu may have pull-right arrows (>) that open a pull-down sub-menu when selected.

Forms and gadgets can have popup menus assigned to them. When you move the cursor onto them and press the mouse popup button, the menu pops-up at the cursor and you can then select from the displayed options.

The following rules determine how you can use menus:

• Each menu belongs either to the Main menu system or to the Popup menu system, but cannot belong to both.

• A menu in the Main system can appear only once. that means, it cannot be a sub-menu of several menus.

• A menu in the Popup system may appear only once in a given popup tree, but may be used in any number of popup trees.

• A menu cannot reference itself, either directly as a pullright of one of its own fields or be a pullright of another menu in its own menu tree.

• Any pullright field of a menu references a sub-menu that will be inferred to be of the same type as the referencing menu.
