Method Detail

getTableCellRendererComponent

public Component getTableCellRendererComponent(JTable table,
                                               Object value,
                                               boolean isSelected,
                                               boolean hasFocus,
                                               int row,
                                               int column)

Returns the component used for drawing the cell. This method is used to configure the renderer appropriately before drawing.

Specified by:

getTableCellRendererComponent in interface TableCellRenderer

Parameters:

table - the JTable that is asking the renderer to draw; can be null

value - the value of the cell to be rendered. It is up to the specific renderer to interpret and draw the value. For example, if value is the string "true", it could be rendered as a string or it could be rendered as a check box that is checked. null is a valid value

isSelected - true if the cell is to be rendered with the selection highlighted; otherwise false

hasFocus - if true, render cell appropriately. For example, put a special border on the cell, if the cell can be edited, render in the color used to indicate editing

row - the row index of the cell being drawn. When drawing the header, the value of row is -1

column - the column index of the cell being drawn

getListCellRendererComponent

public Component getListCellRendererComponent(JList list,
                                              Object value,
                                              int index,
                                              boolean isSelected,
                                              boolean cellHasFocus)

Return a component that has been configured to display the specified value. That component's paint method is then called to "render" the cell. If it is necessary to compute the dimensions of a list because the list cells do not have a fixed size, this method is called to generate a component on which getPreferredSize can be invoked.

Specified by:

getListCellRendererComponent in interface ListCellRenderer

Parameters:

list - The JList we're painting.

value - The value returned by list.getModel().getElementAt(index).

index - The cells index.

isSelected - True if the specified cell was selected.

cellHasFocus - True if the specified cell has the focus.

Returns:

A component whose paint() method will render the specified value.
