Struct FileChooserRequest 

pub struct FileChooserRequest { /* private fields */ }

A request to open a file chooser.

Whenever the user interacts with an HTML input element with file type, WebKit will need to show a dialog to choose one or more files to be uploaded to the server along with the rest of the form data. For that to happen in a general way, instead of just opening a GtkFileChooserDialog (which might be not desirable in some cases, which could prefer to use their own file chooser dialog), WebKit will fire the run-file-chooser signal with a FileChooserRequest object, which will allow the client application to specify the files to be selected, to inspect the details of the request (e.g. if multiple selection should be allowed) and to cancel the request, in case nothing was selected.

In case the client application does not wish to handle this signal, WebKit will provide a default handler which will asynchronously run a regular GtkFileChooserDialog for the user to interact with.

Properties

filter

The filter currently associated with the request. See FileChooserRequest::mime_types_filter() for more details.

Readable

mime-types

A None-terminated array of strings containing the list of MIME types the file chooser dialog should handle. See FileChooserRequest::mime_types() for more details.

Readable

select-multiple

Whether the file chooser should allow selecting multiple files. See FileChooserRequest::selects_multiple() for more details.

Readable

selected-files

A None-terminated array of strings containing the list of selected files associated to the current request. See FileChooserRequest::selected_files() for more details.

Readable

GLib type: GObject with reference counted clone semantics.

Implementations

impl FileChooserRequest

pub fn cancel(&self)

Ask WebKit to cancel the request.

It’s important to do this in case no selection has been made in the client, otherwise the request won’t be properly completed and the browser will keep the request pending forever, which might cause the browser to hang.

pub fn mime_types(&self) -> Vec<GString>

Get the list of MIME types the file chooser dialog should handle.

Get the list of MIME types the file chooser dialog should handle, in the format specified in RFC 2046 for “media types”. Its contents depend on the value of the ‘accept’ attribute for HTML input elements. This function should normally be called before presenting the file chooser dialog to the user, to decide whether to allow the user to select multiple files at once or only one.

Returns

a None-terminated array of strings if a list of accepted MIME types is defined or None otherwise, meaning that any MIME type should be accepted. This array and its contents are owned by WebKit and should not be modified or freed.

pub fn mime_types_filter(&self) -> Option<FileFilter>

Get the filter currently associated with the request.

Get the filter currently associated with the request, ready to be used by GtkFileChooser. This function should normally be called before presenting the file chooser dialog to the user, to decide whether to apply a filter so the user would not be allowed to select files with other MIME types.

See mime_types() if you are interested in getting the list of accepted MIME types.

Returns

a gtk::FileFilter if a list of accepted MIME types is defined or None otherwise. The returned object is owned by WebKit should not be modified or freed.

pub fn selects_multiple(&self) -> bool

Whether the file chooser should allow selecting multiple files.

Determine whether the file chooser associated to this FileChooserRequest should allow selecting multiple files, which depends on the HTML input element having a ‘multiple’ attribute defined.

Returns

true if the file chooser should allow selecting multiple files or false otherwise.

pub fn selected_files(&self) -> Vec<GString>

Get the list of selected files associated to the request.

Get the list of selected files currently associated to the request. Initially, the return value of this method contains any files selected in previous file chooser requests for this HTML input element. Once webkit_file_chooser_request_select_files, the value will reflect whatever files are given.

This function should normally be called only before presenting the file chooser dialog to the user, to decide whether to perform some extra action, like pre-selecting the files from a previous request.

Returns

a None-terminated array of strings if there are selected files associated with the request or None otherwise. This array and its contents are owned by WebKit and should not be modified or freed.

pub fn select_files(&self, files: &[&str])

Ask WebKit to select local files for upload and complete the request.

files

a None-terminated array of strings, containing paths to local files.

pub fn filter(&self) -> Option<FileFilter>

The filter currently associated with the request. See mime_types_filter() for more details.

pub fn connect_filter_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_mime_types_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_select_multiple_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_selected_files_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Trait Implementations

impl Clone for FileChooserRequest

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for FileChooserRequest

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

Formats the value using the given formatter.

impl HasParamSpec for FileChooserRequest

type ParamSpec = ParamSpecObject

type SetValue = FileChooserRequest

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, FileChooserRequest>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FileChooserRequest

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

where H: Hasher,

Hashes the memory address of this object.

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 Ord for FileChooserRequest

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for FileChooserRequest

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for FileChooserRequest

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.
