Struct tauri::api::dialog::FileDialogBuilder

pub struct FileDialogBuilder(_);

Available on crate feature dialog only.

The file dialog builder.

Constructs file picker dialogs that can select single/multiple files or directories.

Implementations

impl FileDialogBuilder

pub fn new() -> Self

Gets the default file dialog builder.

pub fn add_filter(self, name: impl AsRef<str>, extensions: &[&str]) -> Self

Add file extension filter. Takes in the name of the filter, and list of extensions

pub fn set_directory<P: AsRef<Path>>(self, directory: P) -> Self

Set starting directory of the dialog.

pub fn set_file_name(self, file_name: &str) -> Self

Set starting file name of the dialog.

pub fn set_parent<W: HasRawWindowHandle>(self, parent: &W) -> Self

Sets the parent window of the dialog.

pub fn set_title(self, title: &str) -> Self

Set the title of the dialog.

impl FileDialogBuilder

pub fn pick_file<F: FnOnce(Option<PathBuf>) + Send + 'static>(self, f: F)

Shows the dialog to select a single file. This is not a blocking operation, and should be used when running on the main thread to avoid deadlocks with the event loop.

For usage in other contexts such as commands, prefer Self::pick_file.

Examples

use tauri::api::dialog::FileDialogBuilder;
tauri::Builder::default()
  .build(tauri::generate_context!("test/fixture/src-tauri/tauri.conf.json"))
  .expect("failed to build tauri app")
  .run(|_app, _event| {
    FileDialogBuilder::new().pick_file(|file_path| {
      // do something with the optional file path here
      // the file path is `None` if the user closed the dialog
    })
  })

pub fn pick_files<F: FnOnce(Option<Vec<PathBuf>>) + Send + 'static>(self, f: F)

Shows the dialog to select multiple files. This is not a blocking operation, and should be used when running on the main thread to avoid deadlocks with the event loop.

Examples

use tauri::api::dialog::FileDialogBuilder;
tauri::Builder::default()
  .build(tauri::generate_context!("test/fixture/src-tauri/tauri.conf.json"))
  .expect("failed to build tauri app")
  .run(|_app, _event| {
    FileDialogBuilder::new().pick_files(|file_paths| {
      // do something with the optional file paths here
      // the file paths value is `None` if the user closed the dialog
    })
  })

pub fn pick_folder<F: FnOnce(Option<PathBuf>) + Send + 'static>(self, f: F)

Shows the dialog to select a single folder. This is not a blocking operation, and should be used when running on the main thread to avoid deadlocks with the event loop.

Examples

use tauri::api::dialog::FileDialogBuilder;
tauri::Builder::default()
  .build(tauri::generate_context!("test/fixture/src-tauri/tauri.conf.json"))
  .expect("failed to build tauri app")
  .run(|_app, _event| {
    FileDialogBuilder::new().pick_folder(|folder_path| {
      // do something with the optional folder path here
      // the folder path is `None` if the user closed the dialog
    })
  })

pub fn pick_folders<F: FnOnce(Option<Vec<PathBuf>>) + Send + 'static>(
    self,
    f: F
)

Shows the dialog to select multiple folders. This is not a blocking operation, and should be used when running on the main thread to avoid deadlocks with the event loop.

Examples

use tauri::api::dialog::FileDialogBuilder;
tauri::Builder::default()
  .build(tauri::generate_context!("test/fixture/src-tauri/tauri.conf.json"))
  .expect("failed to build tauri app")
  .run(|_app, _event| {
    FileDialogBuilder::new().pick_folders(|file_paths| {
      // do something with the optional folder paths here
      // the folder paths value is `None` if the user closed the dialog
    })
  })

pub fn save_file<F: FnOnce(Option<PathBuf>) + Send + 'static>(self, f: F)

Shows the dialog to save a file.

This is not a blocking operation, and should be used when running on the main thread to avoid deadlocks with the event loop.

Examples

use tauri::api::dialog::FileDialogBuilder;
tauri::Builder::default()
  .build(tauri::generate_context!("test/fixture/src-tauri/tauri.conf.json"))
  .expect("failed to build tauri app")
  .run(|_app, _event| {
    FileDialogBuilder::new().save_file(|file_path| {
      // do something with the optional file path here
      // the file path is `None` if the user closed the dialog
    })
  })
