Extending a widget

Extending a widget allows you to create a new version of an existing widget while retaining its functionality and adding new features.

To extend an existing widget, use the gbc create-widget command as follows: 
gbc create-widget customization/customization-project-dir MyEditWidget --base EditWidget
This command creates a custom widget with the following functionality:
  • Inheritance:
    • MyEditWidget inherits features from EditWidget.
    • You can add new features or override inherited ones in the JavaScript file, MyEditWidget.js.
  • HTML template:
    • The template file MyEditWidget.tpl.html will be empty.
    • Options include copying the original template from EditWidget.tpl.html or creating a new template.
  • Coexistence: Both EditWidget and MyEditWidget can be used together in the application.

For an example extending the MainContainerWidget, go to Extend the MainContainerWidget.
