Just add a ClickHandler to your button that does this when clicked:
for (MyProxy proxy: dataProvider.getList()) {
selectionModel.setSelected(proxy, true);
}
where selectionModel is a MultiSelectionModel and dataProvider is your
table's data provider.
Your checkBoxes will be checked/unchecked in sync with the selectionModel
if you set it up like this:
Column<MyProxy, Boolean> checkColumn = new Column<MyProxy, Boolean>(new
CheckboxCell(true)) {
@Override
public Boolean getValue(MyProxy object) {
return selectionModel.isSelected(object);
}
};
checkColumn.setFieldUpdater(new FieldUpdater<MyProxy, Boolean>() {
public void update(int index, MyProxy object, Boolean value) {
selectionModel.setSelected(object, value);
}
});
