Petr,
listbox.getSelection() returns an array of selected items.
contextMenu.getOpener() is only referring to the same list the context
menu is attached to, so in a simple case it is sufficient to use the
list itself.
This listener deletes the selected items:
delItem.addListener("execute", function(ev) {
var opener = contextMenu.getOpener();
if (listbox.getSelection())
{
var ls = listbox.getSelection();
for (var i=0; i<ls.length; i++)
{
listbox.remove(ls[i]);
}
}
}, this);
The only thing that bothers me is that a right click on an item toggles
its selection (I would expect this only on a left click); I can't say
how to change that behavior.
HTH,
greetings
Stefan
