Implementations
sourceimpl FileChooserWidget
impl FileChooserWidget
sourcepub fn new(action: FileChooserAction) -> FileChooserWidget
pub fn new(action: FileChooserAction) -> FileChooserWidget
Creates a new FileChooserWidget
.
This is a file chooser widget that can be embedded in custom
windows, and it is the same widget that is used by
FileChooserDialog
.
action
Open or save mode for the widget
Returns
a new FileChooserWidget
sourcepub fn builder() -> FileChooserWidgetBuilder
pub fn builder() -> FileChooserWidgetBuilder
Creates a new builder-pattern struct instance to construct FileChooserWidget
objects.
This method returns an instance of FileChooserWidgetBuilder
which can be used to create FileChooserWidget
objects.
pub fn is_search_mode(&self) -> bool
pub fn set_search_mode(&self, search_mode: bool)
pub fn subtitle(&self) -> Option<GString>
sourcepub fn connect_desktop_folder<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_desktop_folder<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to make the file chooser show the user’s Desktop folder in the file list.
The default binding for this signal is Alt-D.
pub fn emit_desktop_folder(&self)
sourcepub fn connect_down_folder<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_down_folder<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to make the file chooser go to a child of the current folder in the file hierarchy. The subfolder that will be used is displayed in the path bar widget of the file chooser. For example, if the path bar is showing “/foo/bar/baz”, with bar currently displayed, then this will cause the file chooser to switch to the “baz” subfolder.
The default binding for this signal is Alt-Down.
pub fn emit_down_folder(&self)
sourcepub fn connect_home_folder<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_home_folder<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to make the file chooser show the user’s home folder in the file list.
The default binding for this signal is Alt-Home.
pub fn emit_home_folder(&self)
sourcepub fn connect_location_popup<F: Fn(&Self, &str) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_location_popup<F: Fn(&Self, &str) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to make the file chooser show a “Location” prompt which the user can use to manually type the name of the file he wishes to select.
The default bindings for this signal are Control-L
with a @path string of “” (the empty string). It is also bound to
/ with a @path string of “/
” (a slash): this lets you
type /
and immediately type a path name. On Unix systems, this is
bound to ~ (tilde) with a @path string of “~” itself for
access to home directories.
path
a string that gets put in the text entry for the file name
pub fn emit_location_popup(&self, path: &str)
sourcepub fn connect_location_popup_on_paste<F: Fn(&Self) + 'static>(

&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to make the file chooser show a “Location” prompt
when the user pastes into a FileChooserWidget
.
The default binding for this signal is Control-V.

&self,
f: F
) -> SignalHandlerId
pub fn connect_places_shortcut<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to move the focus to the places sidebar.
The default binding for this signal is Alt-P.

&self,
f: F
) -> SignalHandlerId
pub fn connect_quick_bookmark<F: Fn(&Self, i32) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user asks for it.
This is a keybinding signal.
This is used to make the file chooser switch to the bookmark specified in the @bookmark_index parameter. For example, if you have three bookmarks, you can pass 0, 1, 2 to this signal to switch to each of them, respectively.
The default binding for this signal is Alt-1, Alt-2, etc. until Alt-0. Note that in the default binding, that Alt-1 is actually defined to switch to the bookmark at index 0, and so on successively.
bookmark_index
the number of the bookmark to switch to

sourcefn watch_closure(&self, closure: &impl AsRef<Closure>)
fn watch_closure(&self, closure: &impl AsRef<Closure>)

to the lifetime of the object. When
the object’s reference count drops to zero, the closure will be
invalidated. An invalidated closure will ignore any calls to
invoke_with_values
, or
invoke
when using Rust closures. Read more
