Re: Creating a CustomRenderer with JComboBox for enums
I was able to use the values() method to get the element of the enum
but now I have another problem, the ComBox does not drop down when I
click on it to select an element other than the default selected one
and I implement the getTableVellRendererComponent but the value I'm
getting are always null for some reason here is the renderer's code:
public class EnumRenderer<V extends Enum<V>> extends JComboBox
implements TableCellRenderer {
Class<V> valueType;
public EnumRenderer() {
// TODO Auto-generated constructor stub
}
public EnumRenderer(ComboBoxModel arg0) {
super(arg0);
// TODO Auto-generated constructor stub
}
public EnumRenderer(Object[] arg0) {
super(arg0);
// TODO Auto-generated constructor stub
}
public EnumRenderer(Vector<?> arg0) {
super(arg0);
// TODO Auto-generated constructor stub
}
public EnumRenderer( Class valueType ){
super(valueType.getEnumConstants());
this.setEnabled(true);
}
@Override
public Component getTableCellRendererComponent(JTable table, Object
value,
boolean isSelected, boolean hasFocus, int row, int column) {
// TODO Auto-generated method stub
System.out.println(value);
/*
if(arg1 != null ){
System.out.println(arg1);
Class<V> valueType = ((Enum)arg1).getDeclaringClass();
for(V v : valueType.getEnumConstants()){
addItem(v);
}
}
*/
return this;
}
}
