Since it wasn't there, I extended DropDownChoice to encapsulate the whole
name/value pair thing:
package ****.****.****.helper.ui;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import org.apache.wicket.markup.html.form.ChoiceRenderer;
import org.apache.wicket.markup.html.form.DropDownChoice;
import org.apache.wicket.model.AbstractPropertyModel;
public class EasyDropDownChoice extends DropDownChoice
{
public EasyDropDownChoice(String componentId, AbstractPropertyModel
model, String[][] options)
{
this(componentId, model, toList(options));
}
public EasyDropDownChoice(String componentId, AbstractPropertyModel
model, Map options)
{
this(componentId, model, toList(options));
}
public EasyDropDownChoice(String componentId, AbstractPropertyModel
model, List<NameValuePair> options)
{
super(componentId, model, options, new ChoiceRenderer("value",
"id"));
}
private static List<NameValuePair> toList(String[][] choices)
{
ArrayList<NameValuePair> options = new
ArrayList<NameValuePair>();
for (int n = 0; n < choices.length; n++)
{
options.add(new NameValuePair(choices[n][0],
choices[n][1]));
}
return options;
}
private static List<NameValuePair> toList(Map<String, String> choices)
{
ArrayList<NameValuePair> options = new
ArrayList<NameValuePair>();
for (String key: choices.keySet())
{
options.add(new NameValuePair(key, choices.get(key)));
}
return options;
}
}
Which depends on:
package ***.*****.****.helper.ui;
import java.io.Serializable;
public class NameValuePair implements Serializable
{
private String id;
private String value;
public NameValuePair(String id, String value)
{
this.id = id;
this.value = value;
}
public String getId()
{
return id;
}
public void setId(String id)
{
this.id = id;
}
public String getValue()
{
return value;
}
public void setValue(String value)
{
this.value = value;
}
}
To initialize it with an array of choices, you now just have to do this:
String[][] eventTimes = new String[][] { {"7:00:00", "7:00 AM"},
{"8:00:00", "8:00 AM"},
{"9:00:00", "9:00 AM"},
{"10:00:00", "10:00 AM"},
{"11:00:00", "11:00 AM"},
{"12:00:00", "12:00 PM"},
{"13:00:00", "1:00 PM"},
{"14:00:00", "2:00 PM"},
{"15:00:00", "3:00 PM"},
{"16:00:00", "4:00 PM"},
{"17:00:00", "5:00 PM"},
{"18:00:00", "6:00 PM"} };
add(new EasyDropDownChoice("eventTime", new PropertyModel(this, "eventTime"),
eventTimes));
You can construct it with either a nested string array or a Map. Just have to
make sure the property it's bound to is of type NameValuePair.
