Method Detail

getHeaderRenderer

protected TableCellRenderer getHeaderRenderer(JTableHeader header,
                                              int columnIndex)

getInsets

public Insets getInsets(Graphics g,
                        JTableHeader header,
                        int columnIndex,
                        Rectangle cellRect)

Description copied from interface: TableHeaderCellDecorator

Gets the margin insets where this cell decorator will paint in. Even though the table header could be in RTL or LTR orientation, we require you return the insets as in LTR orientation and we will properly adjust it based on the actual table header orientation.

Specified by:

getInsets in interface TableHeaderCellDecorator

Parameters:

g - the Graphics instance

header - the table header

columnIndex - the view column index to be painted

cellRect - the original cell rectangle for the column

Returns:

the margin area so the original header cell will not paint over this margin. Null if you don't need to restrict the painting of original header.

paint

public void paint(Graphics g,
                  JTableHeader header,
                  int columnIndex,
                  Rectangle cellRect,
                  boolean mouseOverPaintArea)

Description copied from interface: TableHeaderCellDecorator

Paints the table header cell. This paint method will be called after the original table header cell is painted. Theoretically, you can paint whatever you want but in most cases, you probably want to make sure the painting code is consistent with insets returned from TableHeaderCellDecorator.getInsets(java.awt.Graphics, javax.swing.table.JTableHeader, int, java.awt.Rectangle), i.e., paint only in the area as specified in the insets. You do need to consider both RTL and LTR orientations in your code when doing the painting.

Specified by:

paint in interface TableHeaderCellDecorator

Parameters:

g - the Graphics instance

header - the table header

columnIndex - the view column index to be painted

cellRect - the original cell rectangle for the column

mouseOverPaintArea - the flag indicating if the mouse is over the paint area of this cell decorator

getSortInfo

protected SortableTableHeaderCellDecorator.SortInfo getSortInfo(JTableHeader header,
                                                                int columnIndex)

Gets the sort information of the specified column.

Parameters:

header - the header

columnIndex - the column index

Returns:

SortInfo.
