The GtkScrollbar widget is a horizontal or vertical scrollbar.

Its position and movement are controlled by the adjustment that is passed to or created by Scrollbar(org.gnome.gtk.Orientation, org.gnome.gtk.Adjustment). See Adjustment for more details. The Gtk.Adjustment:value field sets the position of the thumb and must be between Gtk.Adjustment:lower and Gtk.Adjustment:upper - Gtk.Adjustment:page-size. The Gtk.Adjustment:page-size represents the size of the visible scrollable area.

The fields Gtk.Adjustment:step-increment and Gtk.Adjustment:page-increment fields are added to or subtracted from the Gtk.Adjustment:value when the user asks to move by a step (using e.g. the cursor arrow keys) or by a page (using e.g. the Page Down/Up keys).

CSS nodes

 scrollbar
 ╰── range[.fine-tune]
     ╰── trough
         ╰── slider
 

GtkScrollbar has a main CSS node with name scrollbar and a subnode for its contents. The main node gets the .horizontal or .vertical style classes applied, depending on the scrollbar's orientation.

The range node gets the style class .fine-tune added when the scrollbar is in 'fine-tuning' mode.

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).

Accessibility
GtkScrollbar uses the AccessibleRole.SCROLLBAR role.

Constructor Details

Scrollbar

public Scrollbar(MemorySegment address)

Create a Scrollbar proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Scrollbar

public Scrollbar(Orientation orientation,
 @Nullable
 @Nullable Adjustment adjustment)

Creates a new scrollbar with the given orientation.

Parameters:

orientation - the scrollbar’s orientation.

adjustment - the Adjustment to use, or null to create a new adjustment.

Method Details

getType

public static Type getType()

Get the GType of the Scrollbar class

Returns:

the GType

asParent

protected Scrollbar asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Widget

getAdjustment

public Adjustment getAdjustment()

Returns the scrollbar's adjustment.

Returns:

the scrollbar's adjustment

setAdjustment

public void setAdjustment(@Nullable
 @Nullable Adjustment adjustment)

Makes the scrollbar use the given adjustment.

Parameters:

adjustment - the adjustment to set

builder

public static Scrollbar.Builder<? extends Scrollbar.Builder> builder()

A Scrollbar.Builder object constructs a Scrollbar with the specified properties. Use the various set...() methods to set properties, and finish construction with Scrollbar.Builder.build().
