class: ScaleButton

[19:7] extends: object

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 [class@Gtk.VolumeButton] subclass that is tailored for this use case. # Shortcuts and Gestures The following signals have default keybindings: - [signal@Gtk.ScaleButton::popup] # CSS nodes scalebutton.scale ╰── button.toggle ╰── <icon> GtkScaleButton has a single CSS node with name scalebutton and .scale style class, and contains a button node with a .toggle style class.

Methods

• ScaleButton (min = null, max = null, step = null, icons = null)

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

  • @p min is the minimum value of the scale (usually 0).
  • @p max is the maximum value of the scale (usually 100).
  • @p step is the stepping of value when a scroll-wheel event, or up/down arrow event occurs (usually 2).
  • @p icons is a %NULL-terminated array of icon names, or %NULL if you want to set the list later with gtk_scale_button_set_icons().

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asWidget ()

  Wraps this handle as Widget.

  • @r A Widget object.

• asAccessible ()

  • @r A Buildable object.

• asConstraintTarget ()

  Wraps this handle as ConstraintTarget.

  • @r A ConstraintTarget object.

• asOrientable ()

  Wraps this handle as Orientable.

  • @r A Orientable object.

• connectSignal (string Name, CallbackObj)

  • @p HandlerId is the signal handler id to disconnect.
  • @r None.

• setOnPopdown (callback Fn, UserData = null)

  • @p Fn is called with (ScaleButton Self).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.

  • @r The connected handler id.

• setOnValuechanged (callback Fn, UserData = null)

  Emitted when the value field has changed.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (ScaleButton Self, double Value).

  • @p value is new value of the scale button.
  • @r None.
