How to set single selection for GWT multiselect Listbox?

I created multiselect Listbox (with parametr true in constructor). How to set him single select mode with m开发者_开发百科ulti select View (It looks like multi select but I can select only 1 record )?

Thanks

The documentation warns about using setMultipleSelect on InternetExplorer not working, so it may be best to recreate the widget to use false in the constructor. But, on other browsers, this should work:

listBox.setMultipleSelect(false); //single select mode
listBox.setVisibleItemCount(10); //the parameter is the number of rows you want to be visisble.

Again, I think the recommended way would be to create a new ListBox and re-add it, to avoid failure on IE6.
