After a couple of tries Ive managed to write something that gets the
job done.
My example:
List<String> opts = new ArrayList<String>();
opts.add("Enabled");
opts.add("Disabled");
table.addColumn(new IdentityColumn<MyData>(new
ActiveSelectionCell(opts)), "Active");
private class ActiveSelectionCell implements Cell<MyData>{
private HashMap<String, Integer> indexForOption = new
HashMap<String, Integer>();
private final List<String> options;
public ActiveSelectionCell(List<String> options) {
this.options = new ArrayList<String>(options);
int index = 0;
for (String option : options) {
indexForOption.put(option, index++);
}
}
@Override
public boolean consumesEvents() {
return false;
}
@Override
public boolean dependsOnSelection() {
return false;
}
private int getSelectedIndex(String value) {
Integer index = indexForOption.get(value);
if (index == null) {
return -1;
}
return index.intValue();
}
@Override
public void setValue(Element parent, MyData value, Object
viewData)
{
StringBuilder sb = new StringBuilder();
render(value, viewData, sb);
parent.setInnerHTML(sb.toString());
}
@Override
public Object onBrowserEvent(Element parent, MyData value,
Object viewData, NativeEvent event,
ValueUpdater<MyData> valueUpdater) {
String type = event.getType();
if ("change".equals(type)) {
SelectElement select = parent.getFirstChild().cast();
if( options.get(select.getSelectedIndex()).equalsIgnoreCase("Enabled"))
value.setActive("1");
else
value.setActive("0");
System.out.println(value.getName() + " - " +
options.get(select.getSelectedIndex()));
// valueUpdater.update(value);
}
return viewData;
}
@Override
public void render(MyData value, Object viewData, StringBuilder
sb)
{
int selectedIndex = 0;
if(value.getActive().equalsIgnoreCase("1")){
selectedIndex = getSelectedIndex("Enabled");
}else{
selectedIndex = getSelectedIndex("Disabled");
}
sb.append("<select>");
int index = 0;
for (String option : options) {
if (index++ == selectedIndex) {
sb.append("<option selected='selected'>");
} else {
sb.append("<option>");
}
sb.append(option);
sb.append("</option>");
}
sb.append("</select>");
}
}
If you think this was the wrong/not the best way to get an event from
a cell, pleas give me a comment.
