/**
 * @bug #288997: [File Manager] Mouse hover option bar for copy and paste operations, hover tips are displayed outside of the file manager.
 *
 * Handles tooltip events by:
 * - Calculating appropriate tooltip position relative to mouse cursor
 * - Ensuring tooltip remains within screen boundaries
 * - Adjusting position if tooltip would overlap screen edges
 * - Providing debug information about tooltip positioning
 *
 * Normally, just call setToolTip is ok.
 * TODO: need to troubleshoot the underlying qt calculation of the position under wayland to solve this problem completely.
