I have a few buttons, when a button gets clicked it needs to be appended to a display (a TextBox). This done by first writing the pressed buttons to a String. use orbtk::*; use std::vec::Vec; use std::cell::RefCell; use std::rc::Rc; use std::io::Write; use std::str::FromStr; extern crate strum; #…

You don't have ownership, and for some reason that function requires ownership.

[image] ONiel: let screen = screen.clone(); Probably out of my depth, but what if you change the above to let screen = screen.borrow().clone(); Because you are currently cloning a RefCell outside the scope of your move, which I think is probably problematic since the wrapped type does not i…

let screen = screen.borrow().clone(); returns error[E0599]: no method named `clone` found for struct `std::cell::Ref<'_, orbtk_widgets::text_box::TextBox>` in the current scope --> src/main.rs:85:58 | 85 | ... let screen = screen.borrow().clone(); | …

Oh sorry. I must be missing something about the types here. When you borrow an Rc<T> you should get &T, so my assumption was screen.borrow() would give you &RefCell<orbtk_widgets::text_box::TextBox> and RefCell does implement Clone as a method. You could try let screen = std::cell::Ref::<'_, orbtk_…

Thanks for your help. I have no idea on how to implement that though, where would that code belong?

Are you using Orbtk 0.2.27 or the latest version 0.3.1? Looking at the source for 0.2.27 , the on_click API calls for a Fn parameter, which means that let screen = screen.clone() being called in the function you pass as a parameter to on_click is moving the original screen into that closure. Move the…

The fact that text() takes self indicates that this is only meant to be used as part of the Builder pattern; it is strictly for setting the initial text (or for binding it to another object), not for changing the text once the widget is created. I imagine there is simply nothing you can do that wil…

I have made a new code (for the sole purpose of resolving this issue) with only a button and a textbox. The textbox gets updated with the text from the button. use orbtk::*; widget!(MainView<MainViewState>); #[derive(Copy, Clone)] enum Action { Char(char), } #[derive(AsAny, Default)] pub st…

Move occurs because value has type `X`, which does not implement the `Copy` trait

And how would I solve that?
