Preface
寫FTCS XMLPost tool和看書進度緩慢，這個算是寫FTCS XMLPost tool想用的東西。主要的想法是有一塊用JTable來呈現
該Basic Asset Type table的Metadata，然後我可以用勾選的方式，最後產生XMLPost執行的ini設定檔。^^純粹是初步想法
希望會堅持下去用SwingBuilder做完，而不會做到一半覺得改用Wicket做比較快(雖然對我而言是事實)。
Environment
- Groovy 1.6.3
- Sun JDK 1.6.0_10
最初版本和想法
最初是Groovy in Action裡面有關table的範例，作者使用了propertyColumn展示這個componet的做法和功能。以我這個Swing門
外漢想的到，距離心理想要做的東西，針對table還要玩出下列兩項
- closureColumn
- cellRenderer, cellEditor
測試用的殼
Listing. GroovyTest.java
package script;
import java.io.FileNotFoundException;
import java.io.InputStreamReader;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;
public class GroovyTest {
public static void main(String[] args) throws ScriptException, FileNotFoundException {
if(args.length != 1) {
System.err.println("Missing Required Parameter");
System.exit(-1);
} // if
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("groovy");
engine.eval(new InputStreamReader(ClassLoader.getSystemResourceAsStream(args[0])));
} // main()
} // GroovyTest class
closureColumn property
就只是根據書上的範例多的data加一個欄位，用closureColumn來呈現，特別用selected順便在下一個可以用checkbox來
呈現和設定這欄的資料。

cellRenderer, cellEditor property
對Groovy還沒有到那種感覺的程度，所以就只能按照對Swing的了解用Java的方法搞。所以寫了
一個TableCellRenderer。所以先看到的是CheckCellRenderer.groovy之後在tabDemo.groovy裡面
cellRenderer property就設定這個自訂TableCellRenderer，至於CellEdtor則使用DetaulCellEditor
餵給他JCheckBox的物件就可以了。
Listing. CheckCellRenderer.groovy
package script
import java.awt.Component
import javax.swing.JTable
import javax.swing.JCheckBox
import javax.swing.border.EmptyBorder
import javax.swing.table.TableCellRenderer
class CheckCellRenderer extends JCheckBox implements TableCellRenderer {
CheckCellRenderer() {
super()
setOpaque(true)
setBorderPainted(true)
setBorder(new EmptyBorder(1, 1, 1, 1))
setHorizontalAlignment(JCheckBox.CENTER)
}
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column) {
setSelected(value)
setForeground(table.getForeground())
setBackground(table.getBackground())
return this
}
}
