public class CheckBoxListWithSelectable
extends javax.swing.JList
implements java.awt.ItemSelectable

CheckBoxListWithSelectable is a special JList which uses JCheckBox as the list element. In addition to regular JList feature, it also allows you select any number of elements in the list by selecting the check boxes.

The element is ListModel should be an instance of Selectable. If you have your own class that represents the element in the list, you can implement Selectable and implements a few very simple methods. If your elements are already in an array or Vector that you pass in to the constructor of JList, we will convert them to DefaultSelectable which implements Selectable interface.

To select an element, user can mouse click on the check box, or highlight the rows and press SPACE key to toggle the selections.

To listen to the check box selection change, you can call addItemListener to add an ItemListener.

Please note, there are two implementations of CheckBoxList. CheckBoxListWithSelectable is one. There is also another one call CheckBoxList. CheckBoxListWithSelectable is actually the old implementation. In 1.9.2, we introduced a new implementation and renamed the old implementation to CheckBoxListWithSelectable. The main difference between the two implementation is at how the selection state is kept. In new implementation, the selection state is kept at a separate ListSelectionModel which you can get using CheckBoxList.getCheckBoxListSelectionModel(). The old implementation kept the selection state at Selectable object in the ListModel.

CheckBoxListWithSelectable

public CheckBoxListWithSelectable()

Constructs a CheckBoxList with an empty model.

CheckBoxListWithSelectable

public CheckBoxListWithSelectable(java.util.Vector<?> listData)

Constructs a CheckBoxList that displays the elements in the specified Vector. If the Vector contains elements which is not an instance of Selectable, it will wrap it automatically into DefaultSelectable and add to ListModel.

Parameters:

listData - the Vector to be loaded into the data model

CheckBoxListWithSelectable

public CheckBoxListWithSelectable(java.lang.Object[] listData)

Constructs a CheckBoxList that displays the elements in the specified Object[]. If the Object array contains elements which is not an instance of Selectable, it will wrap it automatically into DefaultSelectable and add to ListModel.

Parameters:

listData - the array of Objects to be loaded into the data model

CheckBoxListWithSelectable

public CheckBoxListWithSelectable(javax.swing.ListModel dataModel)

Constructs a CheckBoxList that displays the elements in the specified, non-null model. All CheckBoxList constructors delegate to this one.

Please note, if you are using this constructor, please make sure all elements in dataModel are instance of Selectable.

Parameters:

dataModel - the data model for this list

Throws:

java.lang.IllegalArgumentException - if dataModel is null

Method Detail

init

protected void init()

Initialize the CheckBoxList.

createCellRenderer

protected CheckBoxListCellRenderer createCellRenderer()

Creates the cell renderer.

Returns:

the cell renderer.

createHandler

protected CheckBoxListWithSelectable.Handler createHandler()

Creates the mouse listener and key listener used by CheckBoxList.

Returns:

the Handler.

setSelectedObjects

public void setSelectedObjects(java.lang.Object[] elements)

Sets the selected elements.

Parameters:

elements - the elements to be selected

setSelectedObjects

public void setSelectedObjects(java.util.Vector<?> objects)

Sets the selected objects.

Parameters:

index - the row index.

Returns:

true or false. If false, there is not check box on the particular row index.

setCheckBoxEnabled

public void setCheckBoxEnabled(boolean checkBoxEnabled)

Sets the value of property checkBoxEnabled.
