FileChooser
open class FileChooser : FileChooserProtocol
GtkFileChooser
is an interface that can be implemented by file
selection widgets.
In GTK, the main objects that implement this interface are
[classGtk.FileChooserWidget
] and [classGtk.FileChooserDialog
].
You do not need to write an object that implements the GtkFileChooser
interface unless you are trying to adapt an existing file selector to
expose a standard programming interface.
GtkFileChooser
allows for shortcuts to various places in the filesystem.
In the default implementation these are displayed in the left pane. It
may be a bit confusing at first that these shortcuts come from various
sources and in various flavours, so lets explain the terminology here:
Bookmarks: are created by the user, by dragging folders from the right pane to the left pane, or by using the “Add”. Bookmarks can be renamed and deleted by the user.
Shortcuts: can be provided by the application. For example, a Paint program may want to add a shortcut for a Clipart folder. Shortcuts cannot be modified by the user.
Volumes: are provided by the underlying filesystem abstraction. They are the “roots” of the filesystem.
File Names and Encodings
When the user is finished selecting files in a GtkFileChooser
, your
program can get the selected filenames as GFile
s.
Adding options
You can add extra widgets to a file chooser to provide options
that are not present in the default design, by using
[methodGtk.FileChooser.add_choice
]. Each choice has an identifier and
a user visible label; additionally, each choice can have multiple
options. If a choice has no option, it will be rendered as a
check button with the given label; if a choice has options, it will
be rendered as a combo box.
The FileChooser
type acts as an owner of an underlying GtkFileChooser
instance.
It provides the methods that can operate on this data type through FileChooserProtocol
conformance.
Use FileChooser
as a strong reference or owner of a GtkFileChooser
instance.
-
Untyped pointer to the underlying `GtkFileChooser` instance.
For type-safe access, use the generated, typed pointer
file_chooser_ptr
property instead.Declaration
Swift
public let ptr: UnsafeMutableRawPointer!
-
Designated initialiser from the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init(_ op: UnsafeMutablePointer<GtkFileChooser>)
Parameters
op
pointer to the underlying object
-
Designated initialiser from a constant pointer to the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init(_ op: UnsafePointer<GtkFileChooser>)
Parameters
op
pointer to the underlying object
-
Optional initialiser from a non-mutating
gpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init!(gpointer op: gpointer?)
Parameters
op
gpointer to the underlying object
-
Optional initialiser from a non-mutating
gconstpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init!(gconstpointer op: gconstpointer?)
Parameters
op
pointer to the underlying object
-
Optional initialiser from a constant pointer to the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GtkFileChooser>?)
Parameters
op
pointer to the underlying object
-
Optional initialiser from the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GtkFileChooser>?)
Parameters
op
pointer to the underlying object
-
Designated initialiser from the underlying
C
data type.GtkFileChooser
does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to theFileChooser
instance.Declaration
Swift
@inlinable public init(retaining op: UnsafeMutablePointer<GtkFileChooser>)
Parameters
op
pointer to the underlying object
-
Reference intialiser for a related type that implements
FileChooserProtocol
GtkFileChooser
does not allow reference counting.Declaration

@inlinable public init<T>(_ other: T) where T : FileChooserProtocol
Parameters
other
an instance of a related type that implements
FileChooserProtocol
