StackSwitcher

open class StackSwitcher : Widget, StackSwitcherProtocol

The GtkStackSwitcher shows a row of buttons to switch between GtkStack pages.

An example GtkStackSwitcher

It acts as a controller for the associated GtkStack.

All the content for the buttons comes from the properties of the stacks [classGtk.StackPage] objects; the button visibility in a GtkStackSwitcher widget is controlled by the visibility of the child in the GtkStack.

It is possible to associate multiple GtkStackSwitcher widgets with the same GtkStack widget.

CSS nodes

GtkStackSwitcher has a single CSS node named stackswitcher and style class .stack-switcher.

When circumstances require it, GtkStackSwitcher adds the .needs-attention style class to the widgets representing the stack pages.

Accessibility

GtkStackSwitcher uses the GTK_ACCESSIBLE_ROLE_TAB_LIST role and uses the GTK_ACCESSIBLE_ROLE_TAB for its buttons.

Orientable

Since GTK 4.4, GtkStackSwitcher implements GtkOrientable allowing the stack switcher to be made vertical with gtk_orientable_set_orientation().

The StackSwitcher type acts as a reference-counted owner of an underlying GtkStackSwitcher instance. It provides the methods that can operate on this data type through StackSwitcherProtocol conformance. Use StackSwitcher as a strong reference or owner of a GtkStackSwitcher instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the StackSwitcher instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkStackSwitcher>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the StackSwitcher instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkStackSwitcher>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the StackSwitcher instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the StackSwitcher instance.

    Declaration

    Swift

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
