Hi,
you need an array to store the selected objects, here's un example to a
selection of movies.
Bind the checkbox's selection to "movieSelected" :
public boolean movieSelected() {
return selectedMovies.containsObject(currentMovie);
}
public boolean setMovieSelected(boolean checked) {
boolean isAlreadySelected = movieSelected();
if (!isAlreadySelected && checked)
selectedMovies.addobject(currentMovie);
else if (isAlreadySelected && !checked)
selectedMovies.removeObject(currentMovie);
}
Cheers
Alex
