Class NestedTableColumnHeader

All Implemented Interfaces:
Styleable, EventTarget

public class NestedTableColumnHeader extends TableColumnHeader

This class is used to construct the header of a TableView. We take the approach that every TableView header is nested - even if it isn't. This allows for us to use the same code for building a single row of TableColumns as we would with a heavily nested sequences of TableColumns. Because of this, the TableHeaderRow class consists of just one instance of a NestedTableColumnHeader.

    • createTableColumnHeader

      protected TableColumnHeader createTableColumnHeader(TableColumnBase col)
      Creates a new TableColumnHeader instance for the given TableColumnBase instance. The general pattern for implementing this method is as follows:
      • If the given TableColumnBase instance is null, has no child columns, or if the given TableColumnBase instance equals the TableColumnBase instance returned by calling TableColumnHeader.getTableColumn(), then it is suggested to return a TableColumnHeader instance comprised of the given column.
      • Otherwise, we can presume that the given TableColumnBase instance has child columns, and in this case it is suggested to return a NestedTableColumnHeader instance instead.
      Note: In most circumstances this method should not be overridden, but in some circumstances it makes sense (e.g. testing, or when extreme customization is desired).
