I am trying to have a table that displays data that the user inputs as
well as edit the data. I have figured out how to do this with text
(ie, they can edit the name of something in the table), but I cannot
get it to work with selection cells.
It works correctly if the items in the selection cell are predefined,
but I cannot dynamically update the items in the cell to include new
things after I have created the cell.
To explain more, i have a "type" column. The user enters items into
the table with a given type, but that can also add new types later.
When they click on the item in the type column, I want the dropdown
box to contain all the new types that they have entered, but I don't
know how to accomplish this.
Here is the code I have so far (that doesn't update like I want it
to). record.getTypeList() will contain additional entries after the
user enters new types.
SelectionCell editTypeComboBox = new
SelectionCell(record.getTypeList());
Column<Assignment, String> typeColumn = new Column<Assignment,
String>(editTypeComboBox) {
@Override
public String getValue(Assignment object) {
return object.getType();
}
};
typeColumn.setFieldUpdater(new FieldUpdater<Assignment, String>()
{
@Override
public void update(int index, Assignment object, String value)
{
int row = index;
String newType = value;
record.editAssignType(row, newType);
updateClassGradeLabel();
log.info("Set type to "
+ value);
cellTable.redraw();
}
});
cellTable.addColumn(typeColumn, "Type");
Does anyone have any ideas on how to accomplish this?
