JdbComboBox and ListCellRenderer help

[n perez]

Hello,
I am attempting to use my own:
<code>public Component getListCellRendererComponent</code> with
JdbComboBox, but have been unsuccessful in implementation. I am trying
to get a toolTip popup box to populate with specific information and
pop-up as you mouse over (highlight) an item in the
popup list. I found examples doing this with JComboBox and it works
when I do this with JComboBox.

myJdbComboBox.setRenderer(new ComboBoxRenderer())
.
.
.

class ComboBoxRenderer extends JLabel implements ListCellRenderer {

public Component getListCellRendererComponent(JList list, Object
value, int index, boolean isSelected, boolean cellHasFocus) {
//Get the selected index. (The index param isn't
//always valid, so just use the value.)
if( value != null){
if (isSelected) {
list.setToolTipText(value.toString());
setBackground(list.getSelectionBackground());
setForeground(list.getSelectionForeground());
}
else {
setBackground(list.getBackground());
setForeground(list.getForeground());
}
this.setText( value.toString() );
}
return this;
}
}

....
I also tried....
class ComboBoxRenderer2 extends JLabel implements TableCellRenderer,
ListCellRenderer {.....}

class ComboBoxRenderer2 extends DBCellRenderer implements
ListCellRenderer{....}

class ComboBoxRenderer2 extends BasicComboBoxRenderer{...}

none of which worked. Maybe I am completely lost as to how JdbComboBox
implements its renderer. The toolTip simply does not popup, but the
toolTip value will be set though.

thank you for your help...

Well, after much research and reading, testing,etc... The best solution
is to create your own JComboBox and not to use JDBComboBox.

Mine works like so:

public class JComboBox_Client
extends JComboBox {
public JComboBox_Client() {
try {
jbInit();
}
catch (Exception ex) {
ex.printStackTrace();
}
}

private void jbInit() throws Exception {
this.setRenderer(new MyComboBoxRendererLocal());
this.queryRefresh();
this.setMinimumSize(new Dimension(275, 22));
this.setPreferredSize(new Dimension(400, 22));
this.setSelectedItem(null);
}

public Strnig get_Client_Desc(){
return ((PickListItem)this.getSelectedItem()).getDesc();
}

public String get_Client_Name(){
return ((PickListItem)this.getSelectedItem()).getDisplayName();
}

public BigDecimal get_Client_ID() {
return ((PickListItem)this.getSelectedItem()).getID();
}

public void reset_CompanyAgency() {
this.setSelectedIndex( -1);
this.setSelectedItem(null);
}

public void queryRefresh(){
this.removeAllItems();
ResultSet crSet = null;
try {
crSet = new CachedRowSetImpl();
crSet = myDB.createStatement().executeQuery(query);
crSet.beforeFirst();
this.addItem(new PickListItem(new BigDecimal(-1), ""));
while (crSet.next()) {
this.addItem(new
PickListItem(crSet.getBigDecimal("CLIENT_ID"),
crSet.getString("CLIENT_NAME"),
crSet.getString("CLIENT_DESC"));
}
}
catch (SQLException ex) {
ex.printStackTrace();
}
}

public void setSelectedByClientId(BigDecimal CLIENT_ID){
for (int i = 0; i < this.getItemCount(); i++) {
if ( ((PickListItem)this.getItemAt(i)).getID().equals(CLIENT_ID)) {
this.setSelectedIndex(i);
}
}
}

class MyComboBoxRendererLocal extends JLabel implements
ListCellRenderer {
public MyComboBoxRendererLocal() {
setOpaque(true);
}

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

if ( value != null ){
if (isSelected) {
setForeground(list.getSelectionForeground());
super.setBackground(list.getSelectionBackground());
}
else {
setForeground(list.getForeground());
setBackground(list.getBackground());
}

// Select the current value
setText(((PickListItem) value).getDisplayName().toString());
setToolTipText(((PickListItem)value).getDesc());
}
return this;
}
}

private final String query = "SELECT CLIENT_ID, CLIENT_NAME,
CLIENT_DESC FROM PS_CLIENT_LOOKUP";
private Database myDB = new Database(); //this is your DB conn.
PickListItem listItem = new PickListItem(new BigDecimal(-1), "null");
}

///////Data Type PickListItem

public class PickListItem {
private final BigDecimal id;
private final String displayName;
private final String description;

public PickListItem(BigDecimal id, String displayName, String
description) {
this.id = id;
this.displayName = displayName;
this.description = description;
}

public String getDesc(){
return this.description;
}

public BigDecimal getID(){
return this.id;
}
public String getDisplayName(){
return this.displayName;
}
}

Thanks for contributing your solution. I don't use dbSwing, and
don't even do any UI programming these days, but it's good to see
it when someone does a lot of work and makes an effort to
contribute back to the community.
