<p>
This example continues the theme of the previous two examples and presents the final
standings of the top ten medal-winning countries in the 2008 Summer Olympics in a
<tt>TableView</tt> component. However, rather than representing the data using simple
string-based hash maps or deserialized JSON values, this example uses a custom Java bean
component to represent a table row. In addition to the "nation", "gold", "silver",
"bronze", and "total" properties used in the previous examples, it also defines a
"flag" property of type <tt>org.apache.pivot.wtk.media.Image</tt>, which is shown in
the first column:
</p>
<application class="org.apache.pivot.wtk.ScriptApplication" width="480" height="240">
<libraries>
<library>core</library>
<library>wtk</library>
<library>wtk-terra</library>
<library>tutorials</library>
</libraries>
<startup-properties>
<src>/org/apache/pivot/tutorials/tableviews/custom_table_view.bxml</src>
</startup-properties>
</application>
<p>The Java source for the bean class is as follows:</p>
<source type="java">
<![CDATA[
package org.apache.pivot.tutorials.tableviews;
import java.net.URL;
import org.apache.pivot.util.concurrent.TaskExecutionException;
import org.apache.pivot.wtk.media.Image;
public class OlympicStanding {
private Image flag = null;
private String nation = null;
private int gold = 0;
private int silver = 0;
private int bronze = 0;
public Image getFlag() {
return flag;
}
public void setFlag(Image flag) {
this.flag = flag;
}
public void setFlag(URL flag) {
try {
setFlag(Image.load(flag));
} catch (TaskExecutionException exception) {
throw new IllegalArgumentException(exception);
}
}
public String getNation() {
return nation;
}
public void setNation(String nation) {
this.nation = nation;
}
public int getGold() {
return gold;
}
public void setGold(int gold) {
this.gold = gold;
}
public int getSilver() {
return silver;
}
public void setSilver(int silver) {
this.silver = silver;
}
public int getBronze() {
return bronze;
}
public void setBronze(int bronze) {
this.bronze = bronze;
}
public int getTotal() {
return (gold + silver + bronze);
}
}
]]>
</source>
<p>
The BXML source is as follows. Note that, in this example, the value for "total" no
longer needs to be hard-coded, because it is calculated by the bean class:

<p>
Like the previous example, this one also supports sorting, using the same logic as the
JSON version. The only other major difference between this example and the previous is
the use of relative-width columns in the table view. The "n*" notation used here is
identical to that used by the <a href="table-panes.html">TablePane</a> container
discussed earlier.
