Use DataProvider and SingleSelectionModel for you cellTable:
private final ListDataProvider<SomeClass> dataProvider = new ListDataProvider<SomeClass>();
private final SingleSelectionModel<SomeClass> selectionModel = new SingleSelectionModel<SomeClass>();
//then
table.setSelectionModel(selectionModel);
dataProvider.addDataDisplay(table);
Heres how u can get the selected objects info:
showDataValueOfCellBtn.addClickHandler(new ClickHandler() {
#Override
public void onClick(ClickEvent event) {
SomeClass selected = selectionModel.getSelectedObject();
Window.alert (selected.getValue());
}
});
