HandleBox

open class HandleBox : Bin, HandleBoxProtocol

The GtkHandleBox widget allows a portion of a window to be “torn off”. It is a bin widget which displays its child and a handle that the user can drag to tear off a separate window (the “float window”) containing the child widget. A thin “ghost” is drawn in the original location of the handlebox. By dragging the separate window back to its original location, it can be reattached.

When reattaching, the ghost and float window, must be aligned along one of the edges, the “snap edge”. This either can be specified by the application programmer explicitly, or GTK+ will pick a reasonable default based on the handle position.

To make detaching and reattaching the handlebox as minimally confusing as possible to the user, it is important to set the snap edge so that the snap edge does not move when the handlebox is deattached. For instance, if the handlebox is packed at the bottom of a VBox, then when the handlebox is detached, the bottom edge of the handlebox’s allocation will remain fixed as the height of the handlebox shrinks, so the snap edge should be set to GTK_POS_BOTTOM.

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 HandleBox instance.

    Declaration

    Swift

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

    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 HandleBox 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 HandleBox instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Optional 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 HandleBox instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafePointer<GtkHandleBox>?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the HandleBox instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafeMutablePointer<GtkHandleBox>?)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. Will retain GtkHandleBox. i.e., ownership is transferred to the HandleBox instance.

    Declaration

    Swift

    @inlinable
    public init(retaining op: UnsafeMutablePointer<GtkHandleBox>)

    @inlinable
    public init<T>(handleBox other: T) where T : HandleBoxProtocol

    Parameters
