HScaleRef

public struct HScaleRef : HScaleProtocol, GWeakCapturing

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 HScaleRef type acts as a lightweight Swift reference to an underlying GtkHScale instance. It exposes methods that can operate on this data type through HScaleProtocol conformance. Use HScaleRef only as an unowned reference to an existing GtkHScale instance.

  • ptr 
    Untyped pointer to the underlying `GtkHScale` instance.

    For type-safe access, use the generated, typed pointer hscale_ptr property instead.

  • 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
