Extending existing widgets

Joan_PereAvariento_Vicent — Mon, 23 Oct 2017 16:17:03 GMT

I am trying to extend a existing widget, using as a parent widget, the OverviewMap widget. The problem that I have is how to load or how to refer the widget parent files without loading the parent widget in the app.

I was following the Nick Brueggemann‌ demo in their presentation. But I think that he load the parent and the enhanced widget in the app.

Anyone can help me? rscheitlin‌

Thanks in advance.

Joan,

My preferred method is to copy the parent widget and rename it (be sure to change all the references in the manifest.json). In the video you linked he is extending the existing widget through sub classing. And that would require the parent widget to exist in your deployed app along with the extended widget (that does not mean that the parent widget has to be added to the app though).

Thanks!!

Coping parent widgets and modifying code is the way that i usually use. I would like to develop anything that allow you to separate your code to the original one to make it easier maintaining code.

Thankyou very much. If i develop or find something interesting, i will try to publish and share it.

Robert,

Gavin Rehkemper refer me to his post in a blog where he talk about it. Anyway i would like to develope something that automate the parent widget files to the app when you extend a widget.

Joan,

I would go with the help you get from Gavin then as I do not use that technique or workflow.

Jianxia Song‌ / Lemao Wu‌, would you recommend a different technique to Joan Pere Avariento‌?

Copy and modify is my recommendation.
