I have a Cell Table of which the last column is a checkbox. I would like to
add a Check-All-Box as a footer that when clicked selects every checkbox
for every row. Somehow it won't work here is what I got so far:
private Header<Boolean> initFooterUnSelectAll(){
ValueUpdater<Boolean> updater = new ValueUpdater<Boolean>() {
@Override
public void update(Boolean value) {
for (Object task : getVisibleItems())
task.setSelected(value);
selectAllValue = value;
}
};
Header<Boolean> footer = new CheckboxFooter(updater) {
@Override
public Boolean getValue() {
return selectAllValue;
}
};
return footer;}
private void addColumn() {...
//Header
Header<String> header = new Header<String>(new TextCell()) {
@Override
public String getValue() {
return "HEADER";
}
};
addColumn(COLUMN, header, footerSelectAll());
Does anyone know what I'm doing wrong?
