Constructor Detail

SimpleListModel

public SimpleListModel(java.lang.Object[] data,
                       boolean live)

Constructor.

Parameters:

data - the array to represent

live - whether to have a 'live' ListModel on top of the specified list. If false, the content of the specified list is copied. If true, this object is a 'facade' of the specified list, i.e., when you add or remove items from this ListModelList, the inner "live" list would be changed accordingly. However, it is not a good idea to modify data once it is passed to this method with live is true, since Listbox is not smart enough to hanle it.

Since:

2.4.1
