Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

BasicComboBoxRenderer

public BasicComboBoxRenderer()

Method Detail

getPreferredSize

public Dimension getPreferredSize()

Description copied from class: [JComponent](../../../../javax/swing/JComponent.html#getPreferredSize%28%29)

If the preferredSize has been set to a non-null value just returns it. If the UI delegate's getPreferredSize method returns a non null value then return that; otherwise defer to the component's layout manager.

Overrides:

[getPreferredSize](../../../../javax/swing/JComponent.html#getPreferredSize%28%29) in class [JComponent](../../../../javax/swing/JComponent.html "class in javax.swing")

Returns:

the value of the preferredSize property

getListCellRendererComponent

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

Description copied from interface: [ListCellRenderer](../../../../javax/swing/ListCellRenderer.html#getListCellRendererComponent%28javax.swing.JList, java.lang.Object, int, boolean, boolean%29)

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](../../../../javax/swing/ListCellRenderer.html#getListCellRendererComponent%28javax.swing.JList, java.lang.Object, int, boolean, boolean%29) in interface [ListCellRenderer](../../../../javax/swing/ListCellRenderer.html "interface in javax.swing")

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.

JList, ListSelectionModel, ListModel
