BBjMenuBar

Creation

Description

The BBjMenuBar object provides methods for manipulating a GUI menu bar control.

Creation

A BBjMenuBar object is created through the following BBjTopLevelWindow methods:

Methods of BBjMenuBar

Methods of BBjMenuItem inherited from BBjControl

CSS

The visual appearance of BUI controls is defined using CSS (cascading style sheets) rules. Easily change the default colors, border, and other settings by customizing these rules, all without changing any application code. See CSS API for a high-level overview of BUI CSS.

The BBjMenuBar defines the following style names:

.BBjMenuBar

.BBjMenuBar.bbj-disabled

Remarks

When using the BBjMenuBar object, it is not necessary to create a default menu on the form. Simply create a window without a menu bar and then use the BBjTopLevelWindow.addMenuBar() method to add the menu bar.

All ID values should be negative. If they are not given as negative, they will be changed to negative internally.

All index values are zero-based.

BBjMenuBar: The BBjMenuBar is the top-level bar that fits across the top of the window. BBjMenus are added to the menu bar. Each Top Level window can have one BBjMenuBar.

BBjMenu: A BBjMenu object is a menu that can have menu items and submenus within it. BBjMenu objects can be added to the BBjMenuBar and to other BBjMenus. When they are added to other BBjMenus, an arrow will point from the title and when the arrow is rolled-over, the submenu will appear.

BBjMenuItem: A BBjMenuItem object is a menu item that is not a submenu. They can be added to BBjMenus. The BBjMenuItem can be checkable. In this case a checkbox will appear next to the menu item's title. When the item is selected, the check will toggle.

The image below (Figure 1) illustrates the three different menu objects:
