Implementations

impl FileDialogState

pub fn new() -> Self

pub fn active(&self) -> bool

pub fn set_filter(&mut self, filter: impl Fn(&Path) -> bool + 'static)

Set a filter.

pub fn set_last_path(&mut self, last: &Path)

pub fn use_default_roots(&mut self, roots: bool)

Use the default set of roots.

pub fn no_default_roots(&mut self)

Don’t use default set of roots.

pub fn add_root(&mut self, name: impl AsRef<str>, path: impl Into<PathBuf>)

Add a root path.

pub fn clear_roots(&mut self)

Clear all roots.

pub fn default_roots(&mut self, start: &Path, last: &Path)

Append the default roots.

pub fn directory_dialog(&mut self, path: impl AsRef<Path>) -> Result<(), Error>

Show as directory-dialog.

pub fn open_dialog(&mut self, path: impl AsRef<Path>) -> Result<(), Error>

Show as open-dialog.

pub fn open_many_dialog(&mut self, path: impl AsRef<Path>) -> Result<(), Error>

Show as open-dialog with multiple selection

pub fn save_dialog( &mut self, path: impl AsRef<Path>, name: impl AsRef<str>, ) -> Result<(), Error>

Show as save-dialog.

pub fn save_dialog_ext( &mut self, path: impl AsRef<Path>, name: impl AsRef<str>, ext: impl AsRef<str>, ) -> Result<(), Error>

Show as save-dialog.

Trait Implementations

impl Clone for FileDialogState

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileDialogState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FileDialogState

fn default() -> Self

Returns the “default value” for a type.

impl HandleEvent<Event, Dialog, Result<FileOutcome, Error>> for FileDialogState

fn handle( &mut self, event: &Event, _qualifier: Dialog, ) -> Result<FileOutcome, Error>

Handle an event.

impl HasFocus for FileDialogState

fn build(&self, _builder: &mut FocusBuilder)

Build the focus-structure for the container.

fn focus(&self) -> FocusFlag

Access to the flag for the rest.

fn area(&self) -> Rect

Area for mouse focus.

fn id(&self) -> usize

Provide a unique id for the widget.

fn area_z(&self) -> u16

Z value for the area.

fn navigable(&self) -> Navigation

Declares how the widget interacts with focus.

Just gained focus.

impl HasScreenCursor for FileDialogState

fn screen_cursor(&self) -> Option<(u16, u16)>

This returns the cursor position if

impl RelocatableState for FileDialogState

fn relocate(&mut self, shift: (i16, i16), clip: Rect)

Relocate the areas in this widgets state.

fn relocate_popup(&mut self, shift: (i16, i16), clip: Rect)

Relocate only popup areas. As rendering the popups is a separate render, this has to be separate too.

fn relocate_popup_hidden(&mut self)

fn relocate_hidden(&mut self)

Relocate all areas to a clip-rect (0,0+0x0).
