The way I handled it was toreturn false if the keepExisting flag on
the doBeforeRowSelect event. If your action would clear the selections
of all of the other rows, you cancel the selection. Thus only
selecting the checkbox (or CTRL clicking) the rows will select them.
final CheckboxSelectionModel cbSelectionModel = new
CheckboxSelectionModel();
cbSelectionModel.addListener(new RowSelectionListenerAdapter() {
public boolean doBeforeRowSelect(RowSelectionModel sm,
int rowIndex, boolean keepExisting, Record
record) {
if (!keepExisting) {
return false;
}
return true;
}
});
