Class
GtkScrolledWindow
Description [src]
class Gtk.ScrolledWindow : Gtk.Bin
implements Atk.ImplementorIface, Gtk.Buildable {
priv: GtkScrolledWindowPrivate*
}
GtkScrolledWindow is a container that accepts a single child widget and makes that child scrollable using either internally added scrollbars or externally associated adjustments.
Widgets with native scrolling support, i.e. those whose classes implement the
GtkScrollable
interface, are added directly. For other types of widget, the
class GtkViewport
acts as an adaptor, giving scrollability to other widgets.
GtkScrolledWindow’s implementation of gtk_container_add()
intelligently
accounts for whether or not the added child is a GtkScrollable
. If it isn’t,
GtkScrolledWindow
wraps the child in a GtkViewport
and adds that for you.
Therefore, you can just add any child widget and not worry about the details.
If gtk_container_add()
has added a GtkViewport
for you, you can remove
both your added child widget from the GtkViewport
, and the GtkViewport
from the GtkScrolledWindow, like this:
GtkWidget *scrolled_window = gtk_scrolled_window_new (NULL, NULL);
GtkWidget *child_widget = gtk_button_new ();
// GtkButton is not a GtkScrollable, so GtkScrolledWindow will automatically
// add a GtkViewport.
gtk_container_add (GTK_CONTAINER (scrolled_window),
child_widget);
// Either of these will result in child_widget being unparented:
gtk_container_remove (GTK_CONTAINER (scrolled_window),
child_widget);
// or
gtk_container_remove (GTK_CONTAINER (scrolled_window),
gtk_bin_get_child (GTK_BIN (scrolled_window)));
Unless GtkScrolledWindow:policy
is GTK_POLICY_NEVER or GTK_POLICY_EXTERNAL,
GtkScrolledWindow adds internal GtkScrollbar
widgets around its child. The
scroll position of the child, and if applicable the scrollbars, is controlled
by the GtkScrolledWindow:hadjustment
and GtkScrolledWindow:vadjustment
that are associated with the GtkScrolledWindow. See the docs on GtkScrollbar
for the details, but note that the “step_increment” and “page_increment”
fields are only effective if the policy causes scrollbars to be present.
If a GtkScrolledWindow doesn’t behave quite as you would like, or
doesn’t have exactly the right layout, it’s very possible to set up
your own scrolling with GtkScrollbar
and for example a GtkGrid
.
Touch support
GtkScrolledWindow has built-in support for touch devices. When a
touchscreen is used, swiping will move the scrolled window, and will
expose ‘kinetic’ behavior. This can be turned off with the
GtkScrolledWindow:kinetic-scrolling
property if it is undesired.
GtkScrolledWindow also displays visual ‘overshoot’ indication when
the content is pulled beyond the end, and this situation can be
captured with the GtkScrolledWindow::edge-overshot
signal.
If no mouse device is present, the scrollbars will overlayed as
narrow, auto-hiding indicators over the content. If traditional
scrollbars are desired although no mouse is present, this behaviour
can be turned off with the GtkScrolledWindow:overlay-scrolling
property.
CSS nodes
GtkScrolledWindow has a main CSS node with name scrolledwindow.
It uses subnodes with names overshoot and undershoot to draw the overflow and underflow indications. These nodes get the .left, .right, .top or .bottom style class added depending on where the indication is drawn.
GtkScrolledWindow also sets the positional style classes (.left, .right, .top, .bottom) and style classes related to overlay scrolling (.overlay-indicator, .dragging, .hovering) on its scrollbars.
If both scrollbars are visible, the area where they meet is drawn with a subnode named junction.
Instance methods
gtk_scrolled_window_add_with_viewport
Used to add children without native scrolling capabilities. This
is simply a convenience function; it is equivalent to adding the
unscrollable child to a viewport, then adding the viewport to the
scrolled window. If a child has native scrolling, use
gtk_container_add()
instead of this function.

since: 3.16
Gtk.ScrolledWindow::edge-reached
The ::edge-reached signal is emitted whenever user-initiated scrolling makes the scrolled window exactly reach the lower or upper limits defined by the adjustment in that orientation.
since: 3.16
Gtk.ScrolledWindow::move-focus-out
The ::move-focus-out signal is a
[keybinding signal][GtkBindingSignal] which gets
emitted when focus is moved away from the scrolled window by a
keybinding. The GtkWidget::move-focus
signal is emitted with
direction_type
on this scrolled window’s toplevel parent in the
container hierarchy. The default bindings for this signal are
Ctrl + Tab
to move forward and Ctrl + Shift + Tab
to move backward.
Gtk.ScrolledWindow::scroll-child
The ::scroll-child signal is a [keybinding signal][GtkBindingSignal] which gets emitted when a keybinding that scrolls is pressed. The horizontal or vertical adjustment is updated which triggers a signal that the scrolled window’s child may listen to and scroll itself.
Signals inherited from GtkContainer (4)
GtkContainer::add
GtkContainer::check-resize
GtkContainer::remove
GtkContainer::set-focus-child
Signals inherited from GtkWidget (69)
GtkWidget::accel-closures-changed
GtkWidget::button-press-event
The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.
GtkWidget::button-release-event
The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.
GtkWidget::can-activate-accel
Determines whether an accelerator that activates the signal
identified by signal_id
can currently be activated.
This signal is present to allow applications and derived
widgets to override the default GtkWidget
handling
for determining whether an accelerator can be activated.
GtkWidget::child-notify
The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.
GtkWidget::composited-changed
The ::composited-changed signal is emitted when the composited
status of widgets
screen changes.
See gdk_screen_is_composited().
deprecated: 3.22
GtkWidget::configure-event
The ::configure-event signal will be emitted when the size, position or
stacking of the widget
‘s window has changed.
GtkWidget::damage-event
Emitted when a redirected window belonging to widget
gets drawn into.
The region/area members of the event shows what area of the redirected
drawable was drawn into.
since: 2.14
GtkWidget::delete-event
The ::delete-event signal is emitted if a user requests that
a toplevel window is closed. The default handler for this signal
destroys the window. Connecting gtk_widget_hide_on_delete()
to
this signal will cause the window to be hidden instead, so that
it can later be shown again without reconstructing it.
GtkWidget::destroy
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.
GtkWidget::destroy-event
The ::destroy-event signal is emitted when a GdkWindow
is destroyed.
You rarely get this signal, because most widgets disconnect themselves
from their window before they destroy it, so no widget owns the
window at destroy time.
GtkWidget::direction-changed
The ::direction-changed signal is emitted when the text direction of a widget changes.
GtkWidget::drag-begin
The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().
GtkWidget::drag-data-delete
The ::drag-data-delete signal is emitted on the drag source when a drag
with the action GDK_ACTION_MOVE
is successfully completed. The signal
handler is responsible for deleting the data that has been dropped. What
“delete” means depends on the context of the drag operation.
GtkWidget::drag-data-get
The ::drag-data-get signal is emitted on the drag source when the drop
site requests the data which is dragged. It is the responsibility of
the signal handler to fill data
with the data in the format which
is indicated by info
. See gtk_selection_data_set()
and gtk_selection_data_set_text().
GtkWidget::drag-data-received
The ::drag-data-received signal is emitted on the drop site when the
dragged data has been received. If the data was received in order to
determine whether the drop will be accepted, the handler is expected
to call gdk_drag_status()
and not finish the drag.
If the data was received in response to a GtkWidget::drag-drop
signal
(and this is the last target to be received), the handler for this
signal is expected to process the received data and then call
gtk_drag_finish(), setting the success
parameter depending on
whether the data was processed successfully.
GtkWidget::drag-drop
The ::drag-drop signal is emitted on the drop site when the user drops
the data onto the widget. The signal handler must determine whether
the cursor position is in a drop zone or not. If it is not in a drop
zone, it returns FALSE
and no further processing is necessary.
Otherwise, the handler returns TRUE
. In this case, the handler must
ensure that gtk_drag_finish()
is called to let the source know that
the drop is done. The call to gtk_drag_finish()
can be done either
directly or in a GtkWidget::drag-data-received
handler which gets
triggered by calling gtk_drag_get_data()
to receive the data for one
or more of the supported targets.
GtkWidget::drag-end
The ::drag-end signal is emitted on the drag source when a drag is
finished. A typical reason to connect to this signal is to undo
things done in GtkWidget::drag-begin
.
GtkWidget::drag-failed
The ::drag-failed signal is emitted on the drag source when a drag has
failed. The signal handler may hook custom code to handle a failed DnD
operation based on the type of error, it returns TRUE
is the failure has
been already handled (not showing the default “drag operation failed”
animation), otherwise it returns FALSE
.
since: 2.12
GtkWidget::drag-leave
The ::drag-leave signal is emitted on the drop site when the cursor
leaves the widget. A typical reason to connect to this signal is to
undo things done in GtkWidget::drag-motion
, e.g. undo highlighting
with gtk_drag_unhighlight().
GtkWidget::drag-motion
The ::drag-motion signal is emitted on the drop site when the user
moves the cursor over the widget during a drag. The signal handler
must determine whether the cursor position is in a drop zone or not.
If it is not in a drop zone, it returns FALSE
and no further processing
is necessary. Otherwise, the handler returns TRUE
. In this case, the
handler is responsible for providing the necessary information for
displaying feedback to the user, by calling gdk_drag_status().
GtkWidget::draw
This signal is emitted when a widget is supposed to render itself.
The widget
‘s top left corner must be painted at the origin of
the passed in context and be sized to the values returned by
gtk_widget_get_allocated_width()
and gtk_widget_get_allocated_height().
since: 3.0
GtkWidget::enter-notify-event
The ::enter-notify-event will be emitted when the pointer enters
the widget
‘s window.
GtkWidget::event
The GTK+ main loop will emit three signals for each GDK event delivered
to a widget: one generic ::event signal, another, more specific,
signal that matches the type of event delivered (e.g.
GtkWidget::key-press-event
) and finally a generic
GtkWidget::event-after
signal.
GtkWidget::event-after
After the emission of the GtkWidget::event
signal and (optionally)
the second more specific signal, ::event-after will be emitted
regardless of the previous two signals handlers return values.
GtkWidget::focus
GtkWidget::focus-in-event
The ::focus-in-event signal will be emitted when the keyboard focus
enters the widget
‘s window.
GtkWidget::focus-out-event
The ::focus-out-event signal will be emitted when the keyboard focus
leaves the widget
‘s window.
GtkWidget::grab-broken-event
Emitted when a pointer or keyboard grab on a window belonging
to widget
gets broken.
since: 2.8
GtkWidget::grab-focus
GtkWidget::grab-notify
The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.
GtkWidget::hide
The ::hide signal is emitted when widget
is hidden, for example with gtk_widget_hide().
GtkWidget::hierarchy-changed
The ::hierarchy-changed signal is emitted when the
anchored state of a widget changes. A widget is
“anchored” when its toplevel
ancestor is a GtkWindow
. This signal is emitted when
a widget changes from un-anchored to anchored or vice-versa.
GtkWidget::key-press-event
The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.
GtkWidget::key-release-event
The ::key-release-event signal is emitted when a key is released.
GtkWidget::keynav-failed
Gets emitted if keyboard navigation fails.
See gtk_widget_keynav_failed()
for details.
since: 2.12
GtkWidget::leave-notify-event
The ::leave-notify-event will be emitted when the pointer leaves
the widget
‘s window.
GtkWidget::map
The ::map signal is emitted when widget
is going to be mapped, that is
when the widget is visible (which is controlled with
gtk_widget_set_visible()) and all its parents up to the toplevel widget
are also visible. Once the map has occurred, GtkWidget::map-event
will
be emitted.
GtkWidget::map-event
The ::map-event signal will be emitted when the widget
‘s window is
mapped. A window is mapped when it becomes visible on the screen.
GtkWidget::mnemonic-activate
The default handler for this signal activates widget
if group_cycling
is FALSE
, or just makes widget
grab focus if group_cycling
is TRUE
.
GtkWidget::motion-notify-event
The ::motion-notify-event signal is emitted when the pointer moves
over the widget’s GdkWindow
.
GtkWidget::move-focus
GtkWidget::parent-set
The ::parent-set signal is emitted when a new parent has been set on a widget.
GtkWidget::popup-menu
This signal gets emitted whenever a widget should pop up a context
menu. This usually happens through the standard key binding mechanism;
by pressing a certain key while a widget is focused, the user can cause
the widget to pop up a menu. For example, the GtkEntry
widget creates
a menu with clipboard commands. See the
[Popup Menu Migration Checklist][checklist-popup-menu]
for an example of how to use this signal.
GtkWidget::property-notify-event
The ::property-notify-event signal will be emitted when a property on
the widget
‘s window has been changed or deleted.
GtkWidget::proximity-in-event
To receive this signal the GdkWindow
associated to the widget needs
to enable the #GDK_PROXIMITY_IN_MASK mask.
GtkWidget::proximity-out-event
To receive this signal the GdkWindow
associated to the widget needs
to enable the #GDK_PROXIMITY_OUT_MASK mask.
GtkWidget::query-tooltip
Emitted when GtkWidget:has-tooltip
is TRUE
and the hover timeout
has expired with the cursor hovering “above” widget
; or emitted when widget
got
focus in keyboard mode.
since: 2.12
GtkWidget::realize
The ::realize signal is emitted when widget
is associated with a
GdkWindow
, which means that gtk_widget_realize()
has been called or the
widget has been mapped (that is, it is going to be drawn).
GtkWidget::screen-changed
The ::screen-changed signal gets emitted when the screen of a widget has changed.
GtkWidget::scroll-event
The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.
GtkWidget::selection-clear-event
The ::selection-clear-event signal will be emitted when the
the widget
‘s window has lost ownership of a selection.
GtkWidget::selection-get
GtkWidget::selection-notify-event
GtkWidget::selection-received
GtkWidget::selection-request-event
The ::selection-request-event signal will be emitted when
another client requests ownership of the selection owned by
the widget
‘s window.
GtkWidget::show
The ::show signal is emitted when widget
is shown, for example with gtk_widget_show().
GtkWidget::show-help
GtkWidget::size-allocate
GtkWidget::state-changed
The ::state-changed signal is emitted when the widget state changes. See gtk_widget_get_state().

since: 3.0
GtkWidget::style-set
The ::style-set signal is emitted when a new style has been set
on a widget. Note that style-modifying functions like
gtk_widget_modify_base()
also cause this signal to be emitted.
deprecated: 3.0
GtkWidget::style-updated
The ::style-updated signal is a convenience signal that is emitted when the
GtkStyleContext::changed
signal is emitted on the widget
‘s associated
GtkStyleContext
as returned by gtk_widget_get_style_context().
since: 3.0
GtkWidget::touch-event
GtkWidget::unmap
The ::unmap signal is emitted when widget
is going to be unmapped, which
means that either it or any of its parents up to the toplevel widget have
been set as hidden.
GtkWidget::unmap-event
The ::unmap-event signal will be emitted when the widget
‘s window is
unmapped. A window is unmapped when it becomes invisible on the screen.
GtkWidget::unrealize
The ::unrealize signal is emitted when the GdkWindow
associated with
widget
is destroyed, which means that gtk_widget_unrealize()
has been
called or the widget has been unmapped (that is, it is going to be hidden).
GtkWidget::visibility-notify-event
The ::visibility-notify-event will be emitted when the widget
