Struct zng_wgt_dialog::FileDialogFilters

pub struct FileDialogFilters(/* private fields */);

File dialog filters builder.

Syntax

Display Name|ext1;ext2|All Files|*

You can use the push_filter method to create filters. Note that the extensions are not glob patterns, they must be an extension (without the dot prefix) or * for all files.

Implementations

impl FileDialogFilters

pub fn new() -> FileDialogFilters

New default (empty).

pub fn push_filter<S>( &mut self, display_name: &str, extensions: &[S], ) -> &mut FileDialogFilters

where S: AsRef<str>,

Push a filter entry.

pub fn iter_filters( &self, ) -> impl Iterator<Item = (&str, impl Iterator<Item = &str>)>

Iterate over filter entries and patterns.

pub fn build(self) -> Txt

Gets the filter text.

Trait Implementations

impl Clone for FileDialogFilters

fn clone(&self) -> FileDialogFilters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileDialogFilters

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

Formats the value using the given formatter.

impl Default for FileDialogFilters

fn default() -> FileDialogFilters

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FileDialogFilters

fn deserialize<__D>( __deserializer: __D, ) -> Result<FileDialogFilters, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&'static str> for FileDialogFilters

fn from(filter: &'static str) -> FileDialogFilters

Converts to this type from the input type.

impl From<Txt> for FileDialogFilters

fn from(filter: Txt) -> FileDialogFilters

Converts to this type from the input type.

impl Hash for FileDialogFilters

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoVar<FileDialogFilters> for &'static str

type Var = LocalVar<FileDialogFilters>

Variable type that will wrap the T value.

fn into_var(self) -> <&'static str as IntoVar<FileDialogFilters>>::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl PartialEq for FileDialogFilters

fn eq(&self, other: &FileDialogFilters) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FileDialogFilters

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
