I am trying to extend the inbuilt Select widget in the ArcGIS Web AppBuilder for Desktop using dojo. According to the documentation by ESRI we always inherit the 'dijit/_WidgetBase' module to create the custom widget.
define(['dojo/_base/declare', 'jimu/BaseWidget'],function(declare, BaseWidget) { //To create a widget, you need to derive from BaseWidget. return declare([BaseWidget], { // Custom widget code goes here baseClass: 'jimu-widget-mywidget' });});
Since I wanted the inherit he select widget I changed the code to the following:
define(['dojo/_base/declare', 'widgets/Select/Widget'],function(declare, Select) { //To create a widget, you need to derive from BaseWidget. return declare([Select], { baseClass: 'jimu-widget-selectlsa', startup: function() { this.inherited(arguments); console.log("tesiting") } });});
After copying all the HTML and CSS content from the default Select widget's to my custom widget's HTML and CSS the custom Select widget works fine.
Since I have inherited the default widget's Widget.js file I am able to call functions of the default widget form my custom widget.
However, in the default widget, there is one more file named SelectableLayerItem.js which has a method name _showActions. I tried adding the following code to access the _showActions method in the SelectableLayerItem.js file:
define(['dojo/_base/declare', 'widgets/Select/Widget','widgets/Select/SelectableLayerItem'],function(declare, Select, SelectableLayerItem) { //To create a widget, you need to derive from BaseWidget. return declare([Select, SelectableLayerItem], { baseClass: 'jimu-widget-selectlsa', startup: function() { this.inherited(arguments); console.log("tesiting") }, _showActions: function(){ //overwrite } });});
After running the application, the application runs without any error in the console. However, my custom widget is not able to overwrite the _showActions method in the SelectableLayerItem.js file.
Instead of calling the overwritten method it always calls the default SelectableLayerItem.js's _showActions method.
How can I inherit multiple modules and access their methods independently?
