Nodes in the Menu Tree

Description

The Menu Tree can contain different types of nodes, each representing a specific menu component. These node types are:

• Menubar nodes, to define menubars,

• Toolbar nodes, to define toolbars,

• Popup menu nodes, to define popup menus,

• Menu item nodes, to define menu or toolbar actions,

• Page navigation nodes, to define a set of menu items at once that allow the end-user to navigate through pages, and

• Separator nodes, to define separator lines (in popup menus) or separator spaces (on toolbars).

In addition to these nodes that are closely related to the components of a menu(bar) or toolbar, two other types of nodes are only used for structuring the Menu Tree itself. These structuring nodes are:

• a project or library root node, and

• Section nodes, to group the menubars, toolbars and popup menus that you create.

The following table shows the allowed parent-child relations in the Menu Tree.

Parent Child	Root	Section	Menubar	Toolbar	Popup Menu
Section	✓	✓
Menubar	✓	✓
Toolbar	✓	✓
Popup menu	✓	✓	✓		✓
menu item				✓	✓
Navigator					✓
Separator				✓	✓

Note

• As follows from the table describing the parent-child relations, menu items, page navigation and separator nodes are always leaf nodes in the Menu Tree.

• A menu item can be positioned as a child of a popup menu or as a child of a toolbar. As part of a popup menu, a menu item appears as a command in the menu. As part of a toolbar, a menu item appears as a button on the toolbar.

• Usually, a toolbar button relates to a specific command in the menu. In the Menu Builder, you can easily achieve this by creating a duplicate of the menu item, and position this duplicate as child of the toolbar node. Using a duplicate instead of a copy improves the maintainability of the Menu Tree.
