Examples of jcurses.util.Rectangle

jcurses.util.Rectangle
This is a class to represent an screen rectangle. To implement this class was needed, because java.awt.rectangle works with double's, this is by a text based terminal senseless.

  private void drawItems() {
    Rectangle rect = (Rectangle)getSize().clone();

      if ( index < _items.size()) {
