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.

dispose

getColumnHeaders

public ObservableList<TableColumnHeader> getColumnHeaders()

layoutChildren

protected void layoutChildren()

Description copied from class: TableColumnHeader

Invoked during the layout pass to layout the children in this Parent. By default it will only set the size of managed, resizable content to their preferred sizes and does not do any node positioning.

Subclasses should override this function to layout content as needed.

Overrides:

layoutChildren in class TableColumnHeader

getDragRectHeight

double getDragRectHeight()

Overrides:

getDragRectHeight in class TableColumnHeader

computePrefWidth

protected double computePrefWidth(double height)

Description copied from class: TableColumnHeader

Computes the preferred width of this region for the given height. Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a VERTICAL content bias, then the height parameter can be ignored.

Overrides:

computePrefWidth in class TableColumnHeader

Parameters:

height - the height that should be used if preferred width depends on it

Returns:

the computed preferred width for this region

computePrefHeight

protected double computePrefHeight(double width)

Description copied from class: TableColumnHeader

Computes the preferred height of this region for the given width; Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a HORIZONTAL content bias, then the width parameter can be ignored.

Overrides:

computePrefHeight in class TableColumnHeader

Parameters:

width - the width that should be used if preferred height depends on it

Returns:

the computed preferred height for this region
