set_directory and set_file_name weird behavior on Linux

[lucasfernog]

I'm trying to use the save_file API with a default directory and file_name but the GTK usage is wrong, it doesn't work when the file already exists. I've adapted the save example to test this:

#[cfg(not(target_arch = "wasm32"))]
fn main() {
    let path = std::env::current_dir().unwrap().join("examples");

    let res = rfd::FileDialog::new()
        .set_file_name("async.rs")
        .set_directory(&path)
        .save_file();

    println!("The user choose: {:#?}", res);
}

#[cfg(target_arch = "wasm32")]
fn main() {
    // On wasm only async dialogs are possible
}

If I remove the set_file_name call, at least it changes to the examples folder.

Same thing applies to the pick_file APIs. The following example doesn't work:

#[cfg(not(target_arch = "wasm32"))]
fn main() {
    let path = std::env::current_dir().unwrap().join("examples");

    let res = rfd::FileDialog::new()
        .add_filter("text", &["txt", "rs"])
        .add_filter("rust", &["rs", "toml"])
        .set_directory(&path)
        .set_file_name("async.rs")
        .pick_file();

    println!("The user choose: {:#?}", res);
}

#[cfg(target_arch = "wasm32")]
fn main() {
    // On wasm only async dialogs are possible
}

But it does work if I remove the set_directory call and use .set_file_name(&path.join("async.rs").display().to_string()) instead. Which makes sense if you read the GTK documentation for gtk_file_chooser_set_filename.

In short, I think I could get along with the current API if we could expose set_current_name (only available on Linux). Let me know what you think about this.

Thanks in advance! I love this crate.

Hi!
Could you try master branch, I think I got the conditions right this time 🤞

Works fine now, thanks! I didn't know you were doing all the logic for us ❤️

Yeah, sadly it's probably the only way to hide platform specific details.

Thanks for the report! I'll release a patch release shortly.
