How to select an element in the ListViewer

Question

I'm trying to find and select an element in the ListViewer , I compare a string with every element in the ListViewer .

I can get the index of the element but I don't know how to select it in the Listviewer .

String pattern = elementText.gettext();
String[] listViewerValues = mListViewer.getList().getItems();
List<String> valuesList = Arrays.asList(listViewerValues);  
int index = -1;

for(int i=0; i < valuesList.size(); i++) {
    valuesList.set(i, valuesList.get(i).toLowerCase());
}

index = valuesList.indexOf(pattern);
if(index>-1) 
{
    ***....... what to do here ?*** 
}

Answer 1

You can use the method setSelection(ISelection, boolean) to set the selection.

This will select the element at position :

mListViewer.setSelection(new StructuredSelection(mListViewer.getElementAt(position)), true);
