Connect within update #179

Closed balping closed 5 years ago

balping commented 5 years ago

Hi,

I'm creating widgets dynamically, by reacting to events, inside the update() method. I'd like to add event listeners to the newly created widgets.

How could I use the connect! macro there? I don't seem to have access to the relm object there, just self.

You need to save the relm object in your widget in the model() method, as done here. Then, you'll have access to it in the update() method via self.model.relm.

Ah, thank you. I tried this, by saving a reference, but that didn't work – and I didn't think of clone(). Thanks again.
