Optionalproperties: Partial<Gtk.Clipboard.ConstructorProps>Internal$signalsCompile-time signal type information.
This instance property is generated only for TypeScript type checking. It is not defined at runtime and should not be accessed in JS code.
Static$gtypeClears the contents of the clipboard. Generally this should only
be called between the time you call gtk_clipboard_set_with_owner()
or gtk_clipboard_set_with_data(),
and when the clear_func you supplied is called. Otherwise, the
clipboard may be owned by someone else.
SignalconnectSignalconnect_SignalemitGets the Gdk.Display associated with clipboard

If the clipboard contents callbacks were set with
gtk_clipboard_set_with_owner(), and the gtk_clipboard_set_with_data() or
gtk_clipboard_clear() has not subsequently called, returns the owner set
by gtk_clipboard_set_with_owner().
the owner of the clipboard, if any; otherwise null.
Requests the contents of clipboard as the given target. When the results of the result are later received the supplied callback will be called.
an atom representing the form into which the clipboard owner should convert the selection.
A function to call when the results are received (or the retrieval fails). If the retrieval fails the length field of selection_data will be negative.
Requests the contents of the clipboard as image. When the image is
later received, it will be converted to a GdkPixbuf.Pixbuf, and
callback will be called.
The pixbuf parameter to callback will contain the resulting
GdkPixbuf.Pixbuf if the request succeeded, or null if it failed. This
could happen for various reasons, in particular if the clipboard
was empty or if the contents of the clipboard could not be
converted into an image.
a function to call when the image is received, or the retrieval fails. (It will always be called one way or the other.)
Requests the contents of the clipboard as rich text. When the rich
text is later received, callback will be called.
The text parameter to callback will contain the resulting rich
text if the request succeeded, or null if it failed. The length
parameter will contain text’s length. This function can fail for
various reasons, in particular if the clipboard was empty or if the
contents of the clipboard could not be converted into rich text form.
a function to call when the text is received, or the retrieval fails. (It will always be called one way or the other.)
Requests the contents of the clipboard as list of supported targets.
When the list is later received, callback will be called.
The targets parameter to callback will contain the resulting targets if
the request succeeded, or null if it failed.
a function to call when the targets are received, or the retrieval fails. (It will always be called one way or the other.)
Requests the contents of the clipboard as text. When the text is
later received, it will be converted to UTF-8 if necessary, and
callback will be called.
The text parameter to callback will contain the resulting text if
the request succeeded, or null if it failed. This could happen for
various reasons, in particular if the clipboard was empty or if the
contents of the clipboard could not be converted into text form.
a function to call when the text is received, or the retrieval fails. (It will always be called one way or the other.)
Requests the contents of the clipboard as URIs. When the URIs are
later received callback will be called.
The uris parameter to callback will contain the resulting array of
URIs if the request succeeded, or null if it failed. This could happen
for various reasons, in particular if the clipboard was empty or if the
contents of the clipboard could not be converted into URI form.
a function to call when the URIs are received, or the retrieval fails. (It will always be called one way or the other.)
Hints that the clipboard data should be stored somewhere when the application exits or when gtk_clipboard_store () is called.
This value is reset when the clipboard owner changes. Where the clipboard data is stored is platform dependent, see gdk_display_store_clipboard () for more information.
Optionaltargets: TargetEntry[]array containing information about which forms should be stored or null to indicate that all forms should be stored.
Sets the contents of the clipboard to the given GdkPixbuf.Pixbuf. GTK+ will take responsibility for responding for requests for the image, and for converting the image into the requested format.
Sets the contents of the clipboard to the given UTF-8 string. GTK+ will make a copy of the text and take responsibility for responding for requests for the text, and for converting the text into the requested format.
a UTF-8 string.
length of text, in bytes, or -1, in which case the length will be determined with strlen().
Stores the current clipboard data somewhere so that it will stay around after the application has quit.
Requests the contents of the clipboard using the given target. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
a newly-allocated Gtk.SelectionData object or null if retrieving the given target failed. If non-null, this value must be freed with gtk_selection_data_free() when you are finished with it.
Requests the contents of the clipboard as image and converts the result to a GdkPixbuf.Pixbuf. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
a newly-allocated GdkPixbuf.Pixbuf object which must be disposed with g_object_unref(), or null if retrieving the selection data failed. (This could happen for various reasons, in particular if the clipboard was empty or if the contents of the clipboard could not be converted into an image.)
Requests the contents of the clipboard as rich text. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
a newly-allocated binary block of data which must be freed with g_free(), or null if retrieving the selection data failed. (This could happen for various reasons, in particular if the clipboard was empty or if the contents of the clipboard could not be converted into text form.)
Returns a list of targets that are present on the clipboard, or null
if there aren’t any targets available. The returned list must be
freed with g_free().
This function waits for the data to be received using the main
loop, so events, timeouts, etc, may be dispatched during the wait.
true if any targets are present on the clipboard, otherwise false.
Requests the contents of the clipboard as text and converts the result to UTF-8 if necessary. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
a newly-allocated UTF-8 string which must be freed with g_free(), or null if retrieving the selection data failed. (This could happen for various reasons, in particular if the clipboard was empty or if the contents of the clipboard could not be converted into text form.)
Requests the contents of the clipboard as URIs. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
a newly-allocated null-terminated array of strings which must be freed with g_strfreev(), or null if retrieving the selection data failed. (This could happen for various reasons, in particular if the clipboard was empty or if the contents of the clipboard could not be converted into URI form.)
Test to see if there is an image available to be pasted This is done by requesting the TARGETS atom and checking if it contains any of the supported image targets. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
This function is a little faster than calling
gtk_clipboard_wait_for_image() since it doesn’t need to retrieve
the actual image data.
true is there is an image available, false otherwise.
Test to see if there is rich text available to be pasted This is done by requesting the TARGETS atom and checking if it contains any of the supported rich text targets. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
This function is a little faster than calling
gtk_clipboard_wait_for_rich_text() since it doesn’t need to retrieve
the actual text.
true is there is rich text available, false otherwise.
Checks if a clipboard supports pasting data of a given type. This function can be used to determine if a “Paste” menu item should be insensitive or not.
If you want to see if there’s text available on the clipboard, use gtk_clipboard_wait_is_text_available () instead.
true if the target is available, false otherwise.

StaticgetStaticget_Returns the default clipboard object for use with cut/copy/paste menu items and keyboard shortcuts.
the Gdk.Display for which the clipboard is to be retrieved.
Staticget_Returns the clipboard object for the given selection.
Cut/copy/paste menu items and keyboard shortcuts should use
the default clipboard, returned by passing GDK_SELECTION_CLIPBOARD for selection.
(GDK_NONE is supported as a synonym for GDK_SELECTION_CLIPBOARD
for backwards compatibility reasons.)
The currently-selected object or text should be provided on the clipboard
identified by #GDK_SELECTION_PRIMARY. Cut/copy/paste menu items
conceptually copy the contents of the #GDK_SELECTION_PRIMARY clipboard
to the default clipboard, i.e. they copy the selection to what the
user sees as the clipboard.
(Passing #GDK_NONE is the same as using gdk_atom_intern ("CLIPBOARD", FALSE).
See the FreeDesktop Clipboard Specification for a detailed discussion of the “CLIPBOARD” vs. “PRIMARY” selections under the X window system. On Win32 the #GDK_SELECTION_PRIMARY clipboard is essentially ignored.)
It’s possible to have arbitrary named clipboards; if you do invent new clipboards, you should prefix the selection name with an underscore (because the ICCCM requires that nonstandard atoms are underscore-prefixed), and namespace it as well. For example, if your application called “Foo” has a special-purpose clipboard, you might call it “_FOO_SPECIAL_CLIPBOARD”.
Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget GObject.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
GObject.Binding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A GObject.Object can have multiple bindings.

Creates a binding between source_property on source and target_property

the binding.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well. The transform_from function is only used in case
of bidirectional bindings, otherwise it will be ignored
The binding will automatically be removed when either the source or the
target instances are finalized. This will release the reference that is
being held on the GObject.Binding instance; if you want to hold on to the
GObject.Binding instance, you will need to hold a reference to it.
To remove the binding, call g_binding_unbind().
A GObject.Object can have multiple bindings.
The same user_data parameter will be used for both transform_to
and transform_from transformation functions; the notify function will
be called once, when the binding is removed. If you need different data
for each transformation function, please use
g_object_bind_property_with_closures() instead.

This function is intended for GObject.Object implementations to re-enforce
a [floating][floating-ref] object reference. Doing this is seldom
required: all GInitiallyUnowneds are created with a floating reference
which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
GObject.Object::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

Gets a property of an object.

In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling GObject.Value.unset.

Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than
g_object_notify().
One way to avoid using g_object_notify() from within the
class that registered the properties, and using g_object_notify_by_pspec()
instead, is to store the GParamSpec used with
g_object_class_install_property() inside a static array, e.g.:
typedef enum
{
PROP_FOO = 1,
PROP_LAST
} MyObjectProperty;
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
0, 100,
50,
G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the GObject.ParamSpec of a property installed on the class of object.
Increases the reference count of object.
Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type
of object will be propagated to the return type (using the GCC typeof()
extension), so any casting the caller needs to do on the return type must be
explicit.
the same object
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
object
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.
Object containing the properties to set
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a GLib.Quark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the GLib.Quark storage growing unbounded.

the data if found, or null if no such data exists.
This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of
g_object_steal_qdata() would have left the destroy function set,
and thus the partial string list would have been freed upon
g_object_set_qdata_full().

Reverts the effect of a previous call to

and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one GObject.Object::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.

Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the GObject.Object may be reused in future (for example, if it is
an instance variable of another object), it is recommended to clear the
pointer to null rather than retain a dangling pointer to a potentially
invalid GObject.Object instance. Use g_clear_object() for this.
Virtualvfunc_the constructed function is called by g_object_new() as the
final step of the object creation process. At the point of the call, all
construction properties have been set on the object. The purpose of this
call is to allow for object initialisation steps that can only be performed
after construction properties have been set. constructed implementors
should chain up to the constructed call of their parent class to allow it
to complete its initialisation.
Virtualvfunc_Virtualvfunc_the dispose function is supposed to drop all references to other
objects, but keep the instance otherwise intact, so that client method
invocations still work. It may be run multiple times (due to reference
loops). Before returning, dispose should chain up to the dispose method
of the parent class.
Virtualvfunc_instance finalization function, should finish the finalization of
the instance begun in dispose and chain up to the finalize method of the
parent class.
Virtualvfunc_Virtualvfunc_Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
Virtualvfunc_the generic setter for all properties of this type. Should be
overridden for every type with properties. If implementations of
set_property don't emit property change notification explicitly, this will
be done implicitly by the type system. However, if the notify signal is
emitted explicitly, the type system will not emit it a second time.
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

Staticinterface_Add a property to an interface; this is only useful for interfaces
that are added to GObject-derived types. Adding a property to an

created GObject.ParamSpec, but normally
g_object_class_override_property() will be used so that the object
class only needs to provide an implementation and inherits the
property description, default value, bounds, and so forth from the
interface property.
This function is meant to be called from the interface's default

GObject.TypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.

The Gtk.Clipboard object represents a clipboard of data shared between different processes or between different widgets in the same process. Each clipboard is identified by a name encoded as a Gdk.Atom. (Conversion to and from strings can be done with
gdk_atom_intern()andgdk_atom_name().) The default clipboard corresponds to the “CLIPBOARD” atom; another commonly used clipboard is the “PRIMARY” clipboard, which, in X, traditionally contains the currently selected text.To support having a number of different formats on the clipboard at the same time, the clipboard mechanism allows providing callbacks instead of the actual data. When you set the contents of the clipboard, you can either supply the data directly (via functions like
gtk_clipboard_set_text()), or you can supply a callback to be called at a later time when the data is needed (viagtk_clipboard_set_with_data()orgtk_clipboard_set_with_owner().) Providing a callback also avoids having to make copies of the data when it is not needed.gtk_clipboard_set_with_data()andgtk_clipboard_set_with_owner()are quite similar; the choice between the two depends mostly on which is more convenient in a particular situation. The former is most useful when you want to have a blob of data with callbacks to convert it into the various data types that you advertise. When theclear_funcyou provided is called, you simply free the data blob. The latter is more useful when the contents of clipboard reflect the internal state of a GObject.Object (As an example, for the PRIMARY clipboard, when an entry widget provides the clipboard’s contents the contents are simply the text within the selected region.) If the contents change, the entry widget can callgtk_clipboard_set_with_owner()to update the timestamp for clipboard ownership, without having to worry aboutclear_funcbeing called.Requesting the data from the clipboard is essentially asynchronous. If the contents of the clipboard are provided within the same process, then a direct function call will be made to retrieve the data, but if they are provided by another process, then the data needs to be retrieved from the other process, which may take some time. To avoid blocking the user interface, the call to request the selection,
gtk_clipboard_request_contents()takes a callback that will be called when the contents are received (or when the request fails.) If you don’t want to deal with providing a separate callback, you can also usegtk_clipboard_wait_for_contents(). What this does is run the GLib main loop recursively waiting for the contents. This can simplify the code flow, but you still have to be aware that other callbacks in your program can be called while this recursive mainloop is running.Along with the functions to get the clipboard contents as an arbitrary data chunk, there are also functions to retrieve it as text,
gtk_clipboard_request_text()andgtk_clipboard_wait_for_text(). These functions take care of determining which formats are advertised by the clipboard provider, asking for the clipboard in the best available format and converting the results into the UTF-8 encoding. (The standard form for representing strings in GTK+.)
