Hi guys,
I am trying to add a Column using TextInputCell into a CellTable. The code
is like below:
//the display data class:
public class Foo {
...
//the field to be used in CellTable
int quantity;
...
//setters and getters...
public int getQuantity() {
return quantity;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
...
}
//In the entry point onModuleLoad():
CellTable<Foo> cellTable = new CellTable<Foo>();
final ListDataProvider<Foo> dataProvider = new ListDataProvider<Foo>();
Column<Foo, String> quantityCol = new Column<Foo, String>(cell) {
@Override
public String getValue(Foo object) {
//format the integer with MyFormatter to add thousand separators.
//e.g. 1000 -> 1,000
return MyFormatter.*addSeparator*(object.getQuantity());
}
};
quantityCol.setFieldUpdater(new FieldUpdater<Foo, String>() {
@Override
public void update(int index, Foo object, String value) {
// remove thousand seperator, e.g. 1,000 -> 1000
// and set it back to the object.
object.setQuantity(MyFormatter.*removeSeparator*(value));
//to refresh the display.
dataProvider.refresh();
}
});
//add this column to cellTable
cellTable.addColumn(quantityCol, "Quantity");
//adds cellTable to the dataProvider.
dataProvider.addDataDisplay(cellTable);
//adds it to the RootPanel.
RootPanel.get().add(cellTable);
//creates a data object, and push it into dataProvider to display.
Foo foo = new Foo();
foo.setQuantity(1000);
dataProvider.getList().add(foo);
*Problem*:
The cellTable correctly shows a formatted value 1,000 in the TextInputCell
after the page finished its loading.
After I input a value, e.g. 100000. the TextInputCell remained its display
100000, rather than displaying a formatted value 100,000.
I have debugged that getValue(Foo object) did get invoked after
dataProvider.refresh(), and its return value is as correct as 100,000.
I have tried using cellTable.redraw() instead of dataProvider.refresh(). It
does not work either.
The GWT version I am using is 2.5.0 release.
Does anyone know why the TextInputCell never gets updated accordingly after
Column.getValue(T object), or whether this is the right solution to use
cases like above?
