Functions

gdk_selection_owner_set ()

gboolean
gdk_selection_owner_set (GdkWindow *owner,
                         GdkAtom selection,
                         guint32 time_,
                         gboolean send_event);

gdk_selection_owner_set_for_display ()

gboolean
gdk_selection_owner_set_for_display (GdkDisplay *display,
                                     GdkWindow *owner,
                                     GdkAtom selection,
                                     guint32 time_,
                                     gboolean send_event);

Sets the GdkWindow owner as the current owner of the selection selection .

Parameters

display	the GdkDisplay.
owner	a GdkWindow or `NULL` to indicate that the owner for the given should be unset.
selection	an atom identifying a selection.
time_	timestamp to use when setting the selection. If this is older than the timestamp given last time the owner was set for the given selection, the request will be ignored.
send_event	if `TRUE`, and the new owner is different from the current owner, the current owner will be sent a SelectionClear event.

Returns

TRUE if the selection owner was successfully changed to owner, otherwise FALSE.

Since: 2.2

gdk_selection_owner_get ()

GdkWindow *
gdk_selection_owner_get (GdkAtom selection);

gdk_selection_owner_get_for_display ()

GdkWindow *
gdk_selection_owner_get_for_display (GdkDisplay *display,
                                     GdkAtom selection);

Determine the owner of the given selection.

Note that the return value may be owned by a different process if a foreign window was previously created for that window, but a new foreign window will never be created by this call.

Parameters

display	a GdkDisplay.
selection	an atom indentifying a selection.

Returns

if there is a selection owner for this window, and it is a window known to the current process, the GdkWindow that owns the selection, otherwise NULL.

Since: 2.2

gdk_selection_convert ()

void
gdk_selection_convert (GdkWindow *requestor,
                       GdkAtom selection,
                       GdkAtom target,
                       guint32 time_);

gdk_selection_property_get ()

gint
gdk_selection_property_get (GdkWindow *requestor,
                            guchar **data,
                            GdkAtom *prop_type,
                            gint *prop_format);

Retrieves selection data that was stored by the selection data in response to a call to gdk_selection_convert(). This function will not be used by applications, who should use the GtkClipboard API instead.

Parameters

requestor	the window on which the data is stored
data	location to store a pointer to the retrieved data. If the retrieval failed, `NULL` we be stored here, otherwise, it will be non-`NULL` and the returned data should be freed with `g_free()` when you are finished using it. The length of the allocated memory is one more than the length of the returned data, and the final byte will always be zero, to ensure nul-termination of strings.
prop_type	location to store the type of the property.
prop_format	location to store the format of the property.

Returns

the length of the retrieved data.

gdk_selection_send_notify ()

void
gdk_selection_send_notify (GdkNativeWindow requestor,
                           GdkAtom selection,
                           GdkAtom target,
                           GdkAtom property,
                           guint32 time_);

gdk_selection_send_notify_for_display ()

void
gdk_selection_send_notify_for_display (GdkDisplay *display,
                                       GdkNativeWindow requestor,
                                       GdkAtom selection,
                                       GdkAtom target,
                                       GdkAtom property,
                                       guint32 time_);

Send a response to SelectionRequest event.

Parameters

display	the GdkDisplay where `requestor` is realized
requestor	window to which to deliver response.
selection	selection that was requested.
target	target that was selected.
property	property in which the selection owner stored the data, or `GDK_NONE` to indicate that the request was rejected.
time_	timestamp.
