QlikSenseClassicExtensionDebounceExample.js

define([
    "jquery",
    "qlik",
    "underscore"
    ],
    function ($, qlik, _) {
        'use strict';

        return {
            initialProperties: {},
            definition: {},
            paint: function ($element, layout) {
                var that = this;

                if (!$element.scope().$parent.hasOwnProperty("renderFn")) {
                    $element.scope().$parent.renderFn = _.debounce(renderMe, 400, true);
                }            

                // THE RENDER FUNCTION (my paint fn)
                function renderMe($element, layout, this) {
                
                    // .. just do it
                
                }
                
                function isEditMode() {
                    if (qlik.navigation.getMode() === "analysis") {
                        return false;
                    } else {

                    }
                }
                
                // yea, magic happens here..
                if (isEditMode() || layout.qSelectionInfo.qInSelections) {
                    renderMe($element, layout, _context);
