gtk::PopoverMenu::popup doesn't work for PopoverMenu

[qarmin]

I tried to use PopoverMenu with same functions like in this video - https://www.youtube.com/watch?v=6hE62eXNKU4
But this code(which seems to work )

let popover_select = gtk::PopoverMenu::new();
popover_select.popup();

this error

Here what I suggest: please open a PR with your code (targetting the pending branch if you're using the github version) so I can take a look. So I can help you and in addition, once done, we can merge it so there will be an example for this case.

Do you enable the v3_22 feature on your gtk dependency in Cargo.toml?

[sdroege]

https://gtk-rs.org/docs/gtk/trait.PopoverExt.html#tymethod.popup exists in any case (if you enable that feature), and should be usable. If it isn't, please provide a full testcase like @GuillaumeGomez wrote :)

I completely forgot about enabling gtk v3_24 in my project(I had v3_18).
I had installed on Ubuntu 20.04 gtk 3.24 so I wrongly assumed that everything should works fine.
