A quote from kpanelapplet.h:

<snip>
  /**
   * Notify the panel about a new applet layout.
   *
   * Call this to make the panel relayout all applets, when
   * you want to change your width (horizontal panel) or
   * height (vertical panel).
   *
   * The panel is going to relayout all applets based on their
   * widthForHeight(int height) (horizontal panel) or 
   * heightForWidth(int width) (vertical panel).
   *
   * Please note that the panel may change the applets location
   * if the new widthForHeight(int height) (horizontal panel) or
   * heightForWidth(int width) (vertical panel) does not fit into the
   * current panel layout.
