pub struct Scrollbar { /* private fields */ }Expand description
scrollbar[.fine-tune] ╰── contents ├── [button.up] ├── [button.down] ├── trough │ ╰── slider ├── [button.up] ╰── [button.down] ]|
GtkScrollbar has a main CSS node with name scrollbar and a subnode for its contents, with subnodes named trough and slider.
The main node gets the style class .fine-tune added when the scrollbar is in ‘fine-tuning’ mode.
If steppers are enabled, they are represented by up to four additional subnodes with name button. These get the style classes .up and .down to indicate in which direction they are moving.
Other style classes that may be added to scrollbars inside ScrolledWindow
include the positional classes (.left, .right, .top, .bottom) and style
classes related to overlay scrolling (.overlay-indicator, .dragging, .hovering).

performed on a range. It allows an application to determine the
type of scroll event that occurred and the resultant new value.
The application can handle the event itself and return true to
prevent further processing. Or, by returning false, it can pass

fn add_accelerator( &self, accel_signal: &str, accel_group: &impl IsA<AccelGroup>, accel_key: u32, accel_mods: ModifierType, accel_flags: AccelFlags, )
Installs an accelerator for this
self in accel_group that causes
accel_signal to be emitted if the accelerator is activated.
The accel_group needs to be added to the widget’s toplevel via
GtkWindowExt::add_accel_group(), and the signal must be of type G_SIGNAL_ACTION.
Accelerators added through this function are not user changeable during
runtime. If you want to support accelerators that can be changed by the
user, use gtk_accel_map_add_entry() and set_accel_path() or
GtkMenuItemExt::set_accel_path() instead. Read moreSource§fn add_device_events(&self, device: &Device, events: EventMask)

Adds a widget to the list of mnemonic labels for
this widget. (See
list_mnemonic_labels()). Note the
list of mnemonic labels for the widget is cleared when the
widget is destroyed, so the caller must make sure to update
its internal state at this point as well, by using a connection
to the destroy signal or a weak notifier. Read moreSource§fn can_activate_accel(&self, signal_id: u32) -> bool
fn can_activate_accel(&self, signal_id: u32) -> bool
Determines whether an accelerator that activates the signal
identified by
signal_id can currently be activated.
This is done by emitting the can-activate-accel
signal on self; if the signal isn’t overridden by a
handler or in a derived widget, then the default check is
that the widget must be sensitive, and the widget and all
its ancestors mapped. Read moreSource§fn child_focus(&self, direction: DirectionType) -> bool
fn child_focus(&self, direction: DirectionType) -> bool
This function is used by custom widget implementations; if you’re

Looks for a match between the supported targets of

returning GDK_NONE. dest_target_list should usually be the return
value from drag_dest_get_target_list(), but some widgets may

Given an accelerator group,
accel_group, and an accelerator path,
accel_path, sets up an accelerator in accel_group so whenever the
key binding that is defined for accel_path is pressed, self
will be activated. This removes any accelerators (for any

fn set_device_events(&self, device: &Device, events: EventMask)
Sets the device event mask (see
gdk::EventMask) for a widget. The event
mask determines which events a widget will receive from device. Keep
in mind that different widgets have different default event masks, and by
changing the event mask you may disrupt a widget’s functionality,
so be careful. This function must be called while a widget is
unrealized. Consider add_device_events() for widgets that are
already realized, or if you want to preserve the existing event
mask. This function can’t be used with windowless widgets (which return
false from has_window());

and receive events on the event box. Read moreSource§fn set_direction(&self, dir: TextDirection)
fn set_direction(&self, dir: TextDirection)
Sets the reading direction on a particular widget. This direction
controls the primary direction for widgets containing text,
and also the direction in which the children of a container are
packed. The ability to set the direction is present in order
so that correct localization into languages with right-to-left
reading directions can be done. Generally, applications will
let the default reading direction present, except for containers
where the containers are arranged in an order that is explicitly
visual rather than logical (such as buttons for text justification). Read more

fn connect_drag_drop<F: Fn(&Self, &DragContext, i32, i32, u32) -> bool + 'static>( &self, f: F, ) -> SignalHandlerId
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 drag-data-received handler which gets
triggered by calling drag_get_data() to receive the data for one
or more of the supported targets. Read moreSource§fn connect_drag_end<F: Fn(&Self, &DragContext) + 'static>(

animation), otherwise it returns false. Read moreSource§fn connect_drag_leave<F: Fn(&Self, &DragContext, u32) + 'static>(

fn drag_source_set( &self, start_button_mask: ModifierType, targets: &[TargetEntry], actions: DragAction, )
Sets up a widget so that GTK+ will start a drag operation when the user
clicks and drags on the widget. The widget must have a window. Read more

fn connect_map_event<F: Fn(&Self, &Event) -> Propagation + 'static>( &self, f: F, ) -> SignalHandlerId
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. Read moreSource§fn connect_unmap_event<F: Fn(&Self, &Event) -> Propagation + 'static>(

fn connect_unmap_event<F: Fn(&Self, &Event) -> Propagation + 'static>( &self, f: F, ) -> SignalHandlerId
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. Read moreSource§fn add_tick_callback<P: Fn(&Self, &FrameClock) -> ControlFlow + 'static>(
&self,
callback: P,
) -> TickCallbackId
fn add_tick_callback<P: Fn(&Self, &FrameClock) -> ControlFlow + 'static>( &self, callback: P, ) -> TickCallbackId
Queues an animation frame update and adds a callback to be called
before each frame. Until the tick callback is removed, it will be
called frequently (usually at the frame rate of the output device
or as quickly as the application can be repainted, whichever is
slower). For this reason, is most suitable for handling graphics
that change every frame or every few frames. The tick callback does
not automatically imply a relayout or repaint. If you want a
repaint or relayout, and aren’t changing widget properties that
would trigger that (for example, changing the text of a
Label),
then you will have to call WidgetExt::queue_resize() or
WidgetExt::queue_draw_area() yourself. Read moreSource§fn add_events(&self, events: EventMask)
fn add_events(&self, events: EventMask)
Adds the events in the bitfield
events to the event mask for
self. See WidgetExtManual::set_events() and the
[input handling overview][event-masks] for details. Read moreSource§fn events(&self) -> EventMask
fn events(&self) -> EventMask
Returns the event mask (see
gdk::EventMask) for the widget. These are the
events that the widget will receive. Read moreSource§fn set_events(&self, events: EventMask)
fn set_events(&self, events: EventMask)
Sets the event mask (see
gdk::EventMask) for a widget. The event
mask determines which events a widget will receive. Keep in mind
that different widgets have different default event masks, and by
changing the event mask you may disrupt a widget’s functionality,
so be careful. This function must be called while a widget is
unrealized. Consider WidgetExtManual::add_events() for widgets that are
already realized, or if you want to preserve the existing event
mask. This function can’t be used with widgets that have no window.
(See WidgetExt::has_window()). To get events on those widgets,
place them inside a EventBox and receive events on the event
box. Read moreSource§fn hide_on_delete(&self) -> Propagation
fn hide_on_delete(&self) -> Propagation
Utility function; intended to be connected to the
delete-event
signal on a Window. The function calls WidgetExt::hide() on its
argument, then returns true. If connected to ::delete-event, the
result is that clicking the close button for a window (on the
window frame, top right corner usually) will hide but not destroy
the window. By default, GTK+ destroys windows when ::delete-event
is received. Read more
