Methods

getListCellRendererComponent

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

Description copied from interface: ListCellRenderer

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<Object>

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.
