"action-changed": (arg0: Gdk.DragAction) => void

A new action is being chosen for the drag and drop operation.

This signal will only be emitted if the Gdk.DragContext manages the drag and drop operation. See gdk_drag_context_manage_dnd() for more information.

3.20

cancel: (arg0: Gdk.DragCancelReason) => void

The drag and drop operation was cancelled.

This signal will only be emitted if the Gdk.DragContext manages the drag and drop operation. See gdk_drag_context_manage_dnd() for more information.

3.20

"dnd-finished": () => void

The drag and drop operation was finished, the drag destination finished reading all data. The drag source can now free all miscellaneous data.

This signal will only be emitted if the Gdk.DragContext manages the drag and drop operation. See gdk_drag_context_manage_dnd() for more information.

3.20

"drop-performed": (arg0: number) => void

The drag and drop operation was performed on an accepting client.

This signal will only be emitted if the Gdk.DragContext manages the drag and drop operation. See gdk_drag_context_manage_dnd() for more information.

notify: (arg0: GObject.ParamSpec) => void

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 GObject.ParamFlags.EXPLICIT_NOTIFY, then any call to g_object_set_property() results in ::notify being emitted, even if the new value is the same as the old. If they did pass GObject.ParamFlags.EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_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:

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][class@GObject.ParamSpec#parameter-names] as detail strings for the notify signal.
