ScrolledWindowSignalName
public enum ScrolledWindowSignalName : String, SignalNameProtocol
Undocumented
-
Signals that all holders of a reference to the widget should release the reference that they hold.
May result in finalization of the widget if all references are released.
This signal is not suitable for saving widget state.
Declaration
Swift
case destroy = "destroy"
-
Emitted when the text direction of a widget changes.
Declaration
Swift
case directionChanged = "direction-changed"
-
Emitted whenever user initiated scrolling makes the scrolled window firmly surpass the limits defined by the adjustment in that orientation.
A similar behavior without edge resistance is provided by the [signal
Gtk.ScrolledWindow::edge-reached
] signal.Note: The
pos
argument is LTR/RTL aware, so callers should be aware too if intending to provide behavior on horizontal edges.Declaration
Swift
case edgeOvershot = "edge-overshot"
-
Emitted whenever user-initiated scrolling makes the scrolled window exactly reach the lower or upper limits defined by the adjustment in that orientation.
A similar behavior with edge resistance is provided by the [signal
Gtk.ScrolledWindow::edge-overshot
] signal.Note: The
pos
argument is LTR/RTL aware, so callers should be aware too if intending to provide behavior on horizontal edges.Declaration
Swift
case edgeReached = "edge-reached"
-
Emitted when
widget
is hidden.Declaration
Swift
case hide = "hide"
-
Emitted if keyboard navigation fails.
See [method
Gtk.Widget.keynav_failed
] for details.Declaration
Swift
case keynavFailed = "keynav-failed"
-
Emitted when
widget
is going to be mapped.A widget is mapped when the widget is visible (which is controlled with [property
Gtk.Widget:visible
]) and all its parents up to the toplevel widget are also visible.The
map
signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of [signalGtk.Widget::unmap
].Declaration
Swift
case map = "map"
-
Emitted when a widget is activated via a mnemonic.
The default handler for this signal activates
widget
ifgroup_cycling
isfalse
, or just makeswidget
grab focus ifgroup_cycling
istrue
.Declaration
Swift
case mnemonicActivate = "mnemonic-activate"
-
Emitted when the focus is moved.
Declaration
Swift
case moveFocus = "move-focus"
-
Emitted when focus is moved away from the scrolled window by a keybinding.
This is a keybinding signal.
The default bindings for this signal are
Ctrl + Tab
to move forward andCtrl + Shift + Tab
to move backward.Declaration
Swift
case moveFocusOut = "move-focus-out"
-
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.
Declaration
Swift
case notify = "notify"
-
Emitted when the widgets tooltip is about to be shown.
This happens when the [property
Gtk.Widget:has-tooltip
] property istrue
and the hover timeout has expired with the cursor hovering “above”widget
; or emitted whenwidget
got focus in keyboard mode.Using the given coordinates, the signal handler should determine whether a tooltip should be shown for
widget
. If this is the casetrue
should be returned,false
otherwise. Note that ifkeyboard_mode
istrue
, the values ofx
andy
are undefined and should not be used.The signal handler is free to manipulate
tooltip
with the therefore destined function calls.Declaration
Swift
case queryTooltip = "query-tooltip"
-
Emitted when
widget
is associated with aGdkSurface
.This means that [method
Gtk.Widget.realize
] has been called or the widget has been mapped (that is, it is going to be drawn).Declaration

case realize = "realize"
-

widget
is shown.Declaration

Swift
case unmap = "unmap"
