widget dependency

[leemthai]

My app is basically a big compose() that yields all the app widgets:

yield WidgetA
yield WidgetB
with Container:
  yield WidgetC
  yield WidgetD

It turns out that WidgetC can only be constructed once WidgetA has mounted i.e. WidgetC is dependent on WidgetA

How do I go about coding this widget dependency in the simplest manner possible?

The simplest manner possible would probably be to just mount WidgetC using the app's on_mount method. If you place an on_mount method in your app, it will only be run when all of its children are mounted and ready to go. From there you can create WidgetC and mount it where you need to, and pass any information into it from WidgetA that you require (or get WidgetC to just query WidgetA directly).

This implies you are doing too much in your constructor. If the issue is watchers being invoked before the DOM is ready, then consider using set_reactive which can set a reactive but prevent watchers being called.

That's just a guess. You will need to share more code and any errors before I can offer more suggestions.
