All Implemented Interfaces:

class Menu
extends jsx3.gui.Block

Create GUI menus, similar in functionality to system menus (File, Edit, etc) created by the host OS.

This class implements the CDF interface. Each record represents an item in the rendered menu. The following CDF attributes are supported by default:

jsxid – the required CDF record id
jsxtext – the text displayed in the menu option
jsxtip – the tip displayed when the mouse hovers over the menu option
jsximg – the optional image to display at the far left of the option
jsxexecute – arbitrary JavaScript code to execute when the record is selected
jsxkeycode – the optional key code to use as the hot key for the record. The format of this attribute is according to the method Form.doKeyBinding(). If this attribute is of the form {.*}, then the text between the curly brackets is interpreted as the key of a dynamic property.
jsxdisabled – if "1" the option is disabled, the hot key is disabled and the option may not be selected with the mouse
jsxdivider – if "1" a visual separator is rendered above the option
jsxgroupname – if not empty, the option is grouped with other options with the same value for this attribute. Only one member of the group can be selected at one time.
jsxselected – if "1" a the option is selected and check mark appears on the left side
jsxstyle – additional CSS styles to apply to the option text
