class Gtk::ScaleButton

Overview

Gtk::ScaleButton provides a button which pops up a scale widget.

This kind of widget is commonly used for volume controls in multimedia applications, and GTK provides a Gtk::VolumeButton subclass that is tailored for this use case.

CSS nodes

Gtk::ScaleButton has a single CSS node with name button. To differentiate it from a plain Gtk::Button, it gets the .scale style class.

Constructor Detail

def self.new(min : Float64, max : Float64, step : Float64, icons : Enumerable(String)?) : self #

Creates a Gtk::ScaleButton.

The new scale button has a range between @min and @max, with a stepping of @step.


def self.new #

Initialize a new ScaleButton.

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def adjustment : Gtk::Adjustment #

Gets the Gtk::Adjustment associated with the Gtk::ScaleButton’s scale.

See Gtk::Range#adjustment for details.


def adjustment=(adjustment : Gtk::Adjustment) : Nil #

Sets the Gtk::Adjustment to be used as a model for the Gtk::ScaleButton’s scale.

See Gtk::Range#adjustment= for details.


def adjustment=(value : Gtk::Adjustment?) : Gtk::Adjustment? #

def icons : Enumerable(String) #

def icons=(icons : Enumerable(String)) : Nil #

Sets the icons to be used by the scale button.


def minus_button : Gtk::Button #

Retrieves the minus button of the Gtk::ScaleButton.


def plus_button : Gtk::Button #

Retrieves the plus button of the Gtk::ScaleButton.


def popdown_signal #

def popup : Gtk::Widget #

Retrieves the popup of the Gtk::ScaleButton.


def popup_signal #

def value : Float64 #

Gets the current value of the scale button.


def value=(value : Float64) : Nil #

Sets the current value of the scale.

If the value is outside the minimum or maximum range values, it will be clamped to fit inside them.

The scale button emits the [signal@Gtk.ScaleButton::value-changed] signal if the value changes.


def value_changed_signal #
