[BUG] Dialog not showing up with xdg-desktop-portal > 1.16

[RenjiSann]

Hi,
I am running Arch Linux, with the 6.1 LTS kernel.
I have the xdg-desktop-portal (1.18.0) installed with the xdg-desktop-portal-gtk (1.15.1) backend.

When compiling rfd with the xdg-portal feature, the dialog won't show up.
I was able to make it work by downgrading xdg-desktop-portal to version 1.16, though, so this might be some breaking API changes.

Kind regards,

[RenjiSann]

For references, here are my main.rs and Cargo.toml. I also add that everything works well when using the default feature flags with the gtk backend.

use rfd::FileDialog;

fn main() {
    println!("Hello, world!");

    let files = FileDialog::new()
        .set_directory("/")
        .pick_file();

    println!("files: {:?}", files);
}

[package]
name = "test"
version = "0.1.0"
edition = "2021"


[dependencies]
rfd = { version = "0.12.1", default-features = false, features = [
    "xdg-portal",
] }

I'm having similar issues. The main difference in my setup is I'm using xdg-desktop-portal-hyprland as the backend instead of -gtk.

I have encountered this problem in tauri with xdg-desktop-portal-hyprland

running cargo run --example save --no-default-features --features xdg-portal works on both my desktop arch box running gnome and xdg-desktop-portal 1.18.2 as well as my fedora laptop running the same configuration

Name         : xdg-desktop-portal
Version      : 1.18.2
Name         : xdg-desktop-portal-gtk
Version      : 1.15.1
Name         : xdg-desktop-portal-gnome
Version      : 45.0

Works fine here.

hyperland portal does not provide a file picker, or anything beyond screen sharing. You have to have a portal that does next to hyperland portal. (You can, and should run both)

I have encountered this problem in tauri with xdg-desktop-portal-hyprland

@LIMPIX31
Probably same as above

(PS. just don't mistake freedesktop's gtk portal for gnome portal, as the former one will most likely not work for you on hyperland)

EDIT: Yep. hyperland wiki says the same thing: https://wiki.hyprland.org/Useful-Utilities/Hyprland-desktop-portal/#installing

Hello,

I come from Tauri v2 alpha here, and open a Dialog freeze the application. I'm using archlinux with wayland and hyprland, seems to be related to this.
With the taui v1.3 version I don't have the problem.

The same. I have tried different versions of rfd and xdg-desktop-portal but no result.

[PolyMeilex]

That's unrelated, Tauri does not use xdp backend

For me a workaround is to pin the rfd version to 0.12.0:
rfd = "=0.12.0"

Change this to a newer version (e.g. 0.12.1) causes this issue again.

[PolyMeilex]

How about master? We updated ashpd perhaps that helps somehow

[mibuthu]

With master:
rfd = { git = "https://github.com/PolyMeilex/rfd.git", branch = "master" }
I still have the same issue as with version 0.12.1 or 0.13.0

[PolyMeilex]

How about now? Either master or new 0.14
XDG Backend now has zenity fallback.
And XDG Backend is not the default, without the need to enable any features.

[mibuthu]

Great, for me the issue is solved with version 0.14.0.

==============

Some more information from my testing in the last days:
I my case it seems to be an issue with a combination of rfd with some other framework (in my case slint).

The following minimal code was also working with the problematic versions 0.12.1 and 0.13.0:

use std::path::PathBuf;

fn main() {
	rfd();
}

fn rfd() {
    let current_dir = PathBuf::from("/tmp");
    println!("Current dir: {}", current_dir.display());
    let new_dir: PathBuf = rfd::FileDialog::new()
        .set_title("Folder selection")
        .set_directory(&current_dir)
        .pick_folder()
        .unwrap_or(current_dir)
        .to_string_lossy()
        .to_string()
        .into();
    println!("New dir: {}", new_dir.display());
}

But adding slint to the party with the following code, the problem was reproducible:

use std::path::PathBuf;

slint::slint!{
	import { Button } from "std-widgets.slint";

    export component HelloWorld {
        callback rfd;
        
        Button {
            text: "rfd";
            clicked => { rfd() }
        }
    }
}

fn main() {
	let app = HelloWorld::new().unwrap();
	app.on_rfd({
		move || {
			rfd()
		}
	});
	app.run().unwrap();
}

fn rfd() {
    let current_dir = PathBuf::from("/tmp");
    println!("Current dir: {}", current_dir.display());
    let new_dir: PathBuf = rfd::FileDialog::new()
        .set_title("Folder selection")
        .set_directory(&current_dir)
        .pick_folder()
        .unwrap_or(current_dir)
        .to_string_lossy()
        .to_string()
        .into();
    println!("New dir: {}", new_dir.display());
}
