/**
 * @param frame to be positioned/*ww  w. j  a  v a  2s  .  c  om*/
 * 
 * positions frame on screen relative to position of TOPFRAME.
 * Sets frame.alwaysOnTop to true if TOPFRAME is maximized.

    JFrame topFrame = (JFrame) UIRegistry.getTopWindow();

    // for now this just sets the top of frame to the top of topFrame
    // if there is room on the left side of topFrame, frame is set so it's right edge is next to topFrame's left edge.
    // otherwise, if frame will fit, frame's left edge is aligned with topFrame's right edge.
    // If it won't fit then frame's right edge is aligned with right of edge of screen.
    if (topFrame != null) {
        int x = 0;
