How to intercept the extension of file selection

[yk0n9]

For example, I want to intercept to only select ".txt" files

You can have it only show files with a specific extension by calling filter.

Example:

    let mut file_dlg = egui_file::FileDialog::open_file(None).filter("txt".into());

FYI, I changed filter to take a closure instead of a string. Now you can filter out file paths however you want.

Example:

  let filter = Box::new(|path: &Path| -> bool {
    return path.extension() == Some(OsStr::new("txt"));
  });

  let mut file_dlg = egui_file::FileDialog::open_file(None).filter(filter);
