RangeProtocol

public protocol RangeProtocol : OrientableProtocol, WidgetProtocol

GtkRange is the common base class for widgets which visualize an adjustment, e.g GtkScale or GtkScrollbar.

Apart from signals for monitoring the parameters of the adjustment, GtkRange provides properties and methods for influencing the sensitivity of the “steppers”. It also provides properties and methods for setting a “fill level” on range widgets. See gtk_range_set_fill_level().

The RangeProtocol protocol exposes the methods and properties of an underlying GtkRange instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Range. Alternatively, use RangeRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • The GtkRange::change-value signal is emitted when a scroll action is performed on a range. It allows an application to determine the type of scroll event that occurred and the resultant new value. The application can handle the event itself and return true to prevent further processing. Or, by returning false, it can pass the event to other handlers until the default GTK+ handler is reached.

    The value parameter is unrounded. An application that overrides the GtkRangechange-value signal is responsible for clamping the value to the desired number of decimal digits; the default GTK+ handler clamps the value based on GtkRange:round-digits.

    This represents the underlying change-value signal

  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

    (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.

func getValue() -> Double

  • set(adjustment:) Extension method

    Sets the adjustment to be used as the “model” object for this range widget. The adjustment indicates the current range value, the minimum and maximum range values, the step/page increments used for keybindings and scrolling, and the page size. The page size is normally 0 for GtkScale and nonzero for GtkScrollbar, and indicates the size of the visible area of the widget being scrolled. The page size affects the size of the scrollbar slider.

    Declaration

    Swift

    @inlinable
func set<AdjustmentT>(adjustment: AdjustmentT) where AdjustmentT : AdjustmentProtocol

  • set(fillLevel:) Extension method

    Set the new position of the fill level indicator.

    The “fill level” is probably best described by its most prominent use case, which is an indicator for the amount of pre-buffering in a streaming media player. In that use case, the value of the range would indicate the current play position, and the fill level would be the position up to which the file/stream has been downloaded.

    This amount of prebuffering can be displayed on the range’s trough and is themeable separately from the trough. To enable fill level display, use gtk_range_set_show_fill_level(). The range defaults to not showing the fill level.

    Additionally, it’s possible to restrict the range’s slider position to values which are smaller than the fill level. This is controller by gtk_range_set_restrict_to_fill_level() and is by default enabled.

    Declaration

    Swift

func set(fillLevel: Double)

  • set(flippable:) Extension method

    If a range is flippable, it will switch its direction if it is horizontal and its direction is GTK_TEXT_DIR_RTL.

    Swift

    @inlinable
func set(flippable: Bool)

  • setIncrements(step:page:) Extension method

    Sets the step and page sizes for the range. The step size is used when the user clicks the GtkScrollbar arrows or moves GtkScale via arrow keys. The page size is used for example when moving via Page Up or Page Down keys.

    @inlinable
func setIncrements(step: Double, page: Double)

  • setInverted(setting:) Extension method

    Ranges normally move from lower to higher values as the slider moves from top to bottom or left to right. Inverted ranges have higher values at the top or on the right rather than on the bottom or left.

    Declaration

    Swift

    @inlinable
func setInverted(setting: Bool)
    Show on GitHub

  • Sets the sensitivity policy for the stepper that points to the ‘lower’ end of the GtkRange’s adjustment.

  • setMinSliderSize(minSize:) Extension method

    Sets the minimum size of the range’s slider.

    This function is useful mainly for GtkRange subclasses.

    set_min_slider_size is deprecated: Use the min-height/min-width CSS properties on the slider node.

  • setRange(min:max:) Extension method

    Sets the allowable values in the GtkRange, and clamps the range value to be between min and max. (If the range has a non-zero page size, it is clamped between min and max - page-size.)

  • setSlider(sizeFixed:) Extension method

    Sets whether the range’s slider has a fixed size, or a size that depends on its adjustment’s page size.

  • set(value:) Extension method

    Sets the current value of the range; if the value is outside the minimum or maximum range values, it will be clamped to fit inside them. The range emits the GtkRange::value-changed signal if the value changes.
