Well. I'll explain better... and thanks for answer  :-D
My app has 3 view modes: 2 tables and 1 gallery.
I have a button that rotates between these 3 views.
When the user push a button, the program rotates between these views, as 
i said before. The program fill the view perfectly, but when the 
selected view is populated, i want to show the first elements (if not 
empty). The order is "selectItem(int itemNumber);"

Then, the code for tables is this:


public void selectItemNumber(int item) {
		if (GlobalSettings.moviesList.size() > 0) {
			moviesTable.setFocus();
			moviesTable.setSelection(item);
			moviesTable.notifyListeners(SWT.Selection, new Event());
			return;
		} else {
			return;
		}
	}



This works for the tables, but with the gallery don't.
I've tried the same for gallery but it's impossible.
