GestureLongPressSignalName
public enum GestureLongPressSignalName : String, SignalNameProtocol
Undocumented
-
This signal is emitted when the gesture is recognized. This means the number of touch sequences matches
GtkGesture:n-points
, and theGtkGesture::check
handler(s)
returnedTRUE
.Note: These conditions may also happen when an extra touch (eg. a third touch on a 2-touches gesture) is lifted, in that situation
sequence
won’t pertain to the current set of active touches, so don’t rely on this being true.Declaration
Swift
case begin = "begin"
-
This signal is emitted whenever a sequence is cancelled. This usually happens on active touches when
gtk_event_controller_reset()
is called ongesture
(manually, due to grabs…), or the individualsequence
was claimed by parent widgets’ controllers (seegtk_gesture_set_sequence_state()
).gesture
must forget everything aboutsequence
as a reaction to this signal.Declaration
Swift
case cancel = "cancel"
-
This signal is emitted whenever a press moved too far, or was released before
GtkGestureLongPress::pressed
happened.Declaration
Swift
case cancelled = "cancelled"
-
This signal is emitted when
gesture
either stopped recognizing the event sequences as something to be handled (theGtkGesture::check
handler returnedfalse
), or the number of touch sequences became higher or lower thanGtkGesture:n-points
.Note:
sequence
might not pertain to the group of sequences that were previously triggering recognition ongesture
(ie. a just pressed touch sequence that exceedsGtkGesture:n-points
). This situation may be detected by checking throughgtk_gesture_handles_sequence()
.Declaration
Swift
case end = "end"
-
The notify signal is emitted on an object when one of its properties has its value set through
g_object_set_property()
,g_object_set()
, et al.Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with
G_PARAM_EXPLICIT_NOTIFY
, then any call tog_object_set_property()
results innotify
being emitted, even if the new value is the same as the old. If they did passG_PARAM_EXPLICIT_NOTIFY
, then this signal is emitted only when they explicitly callg_object_notify()
org_object_notify_by_pspec()
, and common practice is to do that only when the value has actually changed.This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the
g_signal_connect()
call, like this:(C Language Example):
g_signal_connect (text_view->buffer, "notify::paste-target-list", G_CALLBACK (gtk_text_view_target_list_notify), text_view)
It is important to note that you must use canonical parameter names as detail strings for the notify signal.
