Gtk::HScale.new(adj)

Creates a new Gtk::HScale.

• adj: the Gtk::Adjustment which sets the range of the scale.
• Returns: a new Gtk::HScale.

Gtk::HScale.new(min, max, step)

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.

• min: minimum value(Float)
• max: maximum value(Float)
• step: step increment (tick size) used with keyboard shortcuts(Float)
• Returns: a new Gtk::HScale

Example:

Gtk::HScale.new(0.0, 5.0, 0.1)

This would set a new scale that starts at 0.0, goes up to 5.0, and goes in incremental steps of + or - 0.1.
