I believe u are talking about CellTable widget. If so..
Define a Header object;
Implement the getValue method.
The header accepts a cell object in its constructor.
U can define any Cell like CheckBoxCell etc.
CheckboxCell cb=new CheckboxCell();
Header<Boolean> hdr=new Header<Boolean>(cb) {
@Override
public Boolean getValue() {
return false;//return true to see a checked
checkbox.
}
};
CellTable ct=new CellTable();
ct.addColumn(colCell,hdr);
colCell is defined elsewhere.
Hope this helps.
Thanks,
Subhro.
