Interface IColumnModel

All Known Implementing Classes:

DefaultColumnModel

public interface IColumnModel

A column model interface that will be used by the tree table's column header component. The interface distinguishes between regular tree table columns and the special key column. The key column is the column in which the tree structure of the Gantt chart model will become visible and in which the table cells display the key object of the tree nodes. Attached listeners will be informed when columns get added, removed or inserted.
