HScale

open class HScale : Scale, HScaleProtocol

The GtkHScale widget is used to allow the user to select a value using a horizontal slider. To create one, use gtk_hscale_new_with_range().

The position to show the current value, and the number of decimal places shown can be set using the parent GtkScale class’s functions.

GtkHScale has been deprecated, use GtkScale instead.

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

    Declaration

    Swift

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

    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 HScale instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Creates a new GtkHScale.

    new is deprecated: Use gtk_scale_new() with %GTK_ORIENTATION_HORIZONTAL instead

    Declaration

public init<AdjustmentT>(adjustment: AdjustmentT?) where AdjustmentT : AdjustmentProtocol
    Show on GitHub

  • Creates a new horizontal scale widget that lets the user input a number between min and max (including min and max) with the increment step. step must be nonzero; it’s the distance the slider moves when using the arrow keys to adjust the scale value.

    Note that the way in which the precision is derived works best if step is a power of ten. If the resulting precision is not suitable for your needs, use gtk_scale_set_digits() to correct it.

    new_with_range is deprecated: Use gtk_scale_new_with_range() with %GTK_ORIENTATION_HORIZONTAL instead

    Declaration
