Instance Method Details

#new(adjustment) ⇒ Gtk::Widget

Creates a new Gtk::VScale.

Parameters:

• adjustment (Gtk::Adjustment) —

  the Gtk::Adjustment which sets the range of the scale.

Returns:

• (Gtk::Widget) —

  a new Gtk::VScale.

#new_with_range(min, max, step) ⇒ Gtk::Widget

Creates a new vertical 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.

Parameters:

• min (Float) —

  minimum value

• max (Float) —

  maximum value

• step (Float) —

  step increment (tick size) used with keyboard shortcuts

Returns:

• (Gtk::Widget) —

  a new Gtk::VScale
