Method Detail

getGravityTracker

public GravityTracker getGravityTracker(String menuString)

This method will fetch an existing menu or create a new one if a menu with the specified name does not exist. The menu name is specified with a '.' delimited string, such that each token creates a new child menu. Insertion locations are determined in two possible ways: 1) a "gravity" or "weight" may be specified in square brackets after each item name. If the gravity has been omitted, the insertion location will be based on a case-insensitive alphanumeric ordering. An example of a string using weights is "File[10].New[40]".

Parameters:

menuString - A '.' delimited string identifying menu names.

Returns:

The last child JMenu object specified by the menu_string parameter.
