Examples of org.eclipse.jface.text.TextSelection

org.eclipse.jface.text.TextSelection
Standard implementation of {@link org.eclipse.jface.text.ITextSelection}.
Makes advantage of the weak contract of correctness of its interface. If generated from a selection provider, it only remembers its offset and length and computes the remaining information on request.

    JavaEditor editor = closeAndOpenEditor();


    // Set the editor to select the package declaration:
    int offset = getDocument(editor).get().indexOf(pkg.getElementName());
    int len = pkg.getElementName().length();
    editor.getSelectionProvider().setSelection(new TextSelection(offset, len));


    // Run the tracker to capture the event:
    long preStart = System.currentTimeMillis();
    tracker.setEnabled(true);
    long postStart = System.currentTimeMillis();
