How can I get the value of the Entry?

[AaronErhardt]

There are two options:

1. You store the value of the entry in your model. The easiest way to do this is to create an EntryBuffer and store it inside the model. Then you use set_buffer to set the buffer of the entry in the view! macro. Whenever you want to get the value of the entry you can the just call self.buffer_name.text() in the update method.

2. You name your entries and move them into the button closure:

connect_clicked(sender, entry1_name, entry2_name) => move |_| {
   let user_name = entry1_name.buffer().text();
   let password = entry2_name.buffer().text();
   send!(sender, AppMsg::Login((user_name, password)));
},

I hope this helps you :)

You can learn Relm4 with the book, the examples or the documentation. You can find all those links in the Readme.
