Interface IColumnHeaderRenderer

All Known Implementing Classes:

DefaultColumnHeaderRenderer

public interface IColumnHeaderRenderer

A renderer used to visualize the individual headers of columns. Each column can have its own renderer depending on the type of the header value (see TreeTableColumn.getHeaderValue()). Header renderers need to make sure that they visualize the sorting direction if sorting is applied on a column.
