Examples

// An entirely default Open File dialog box with no customization

// A folder-picker Open dialog box with a custom dialog title
let params = wfd::DialogParams {
   options: wfd::FOS_PICKFOLDERS,
   title: "My custom open folder dialog",
   ..Default::default()
};
let result = wfd::open_dialog(params)?;
let path = result.selected_file_path;

// An Open dialog box with a custom dialog title and file types
let params = wfd::DialogParams {
   title: "My custom open file dialog",
   file_types: vec![("JPG Files", "*.jpg;*.jpeg"), ("PDF Files", "*.pdf")],
   ..Default::default()

let result = wfd::open_dialog(params)?;
let path = result.selected_file_path;

Errors

If a user cancels the dialog, the UserCancelled error is returned. The only other kinds of errors that can be retured are COM HRESULT failure codes - usually as the result of invalid combinations of options. These are returned in a HResultFailed error
