Are there any plans on merging this?

[wusyong]

We plan to switch to winit as #470 described. So winit also needs to implement this one.
@amrbashir Do you think we should merge this?

[amrbashir]

last time I checked, the winit team has not decided on how they want to introduce this so I think we should keep this open until we make the switch.

[alchaplinsky]

@wusyong By switching you mean that winit will be used in tauri as a window management library instead of tao?

We plan to do so in v2.0. If it's not that urgent, I suppose open a PR on winit is a good start.

[alchaplinsky]

@wusyong Ok got it. Makes sense. But is there a way currently in tauri to handle this issue tauri-apps/tauri#3084 (opening a window on dock icon click)?

[wusyong]

I don't think so until this PR is merged in winit.

Use minimized windows instead of hide.

tauri::Builder::default()
    .on_window_event(|event| {
        if let tauri::WindowEvent::CloseRequested { api, .. } = event.event() {
            // event.window().hide().unwrap();
            event.window().minimize().unwrap();
            api.prevent_close();
        }
    })

Would love to see this in the next version of Tauri. Missing this functionality. Great work.

[amrbashir]

Thanks @BillGoldenWater for your work and sorry for the very long delay, do you plan to work on adding this event to tauri?
