Sets our main struct and passes it to the parent class.
Creates a new #GtkHScale.
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.

Adds a mark at @value.
Removes any marks that have been added with gtk_scale_add_mark().
Gets the number of decimal places to which the value is rounded on change. This number is also used by the default #GtkScale::format-value handler.
Returns whether the current value is displayed as a string next to the slider.
Returns whether the scale has an origin.
Gets the #PangoLayout used to display the scale. The returned object is owned by the scale so does not need to be freed by the caller.
Obtains the coordinates where the scale will draw the #PangoLayout representing the text in the scale. Remember when using the #PangoLayout function you need to convert to and from pixels using PANGO_PIXELS() or #PANGO_SCALE.
Gets the position in which the current value is displayed.
Sets the number of decimal places to which the value is rounded when it is changed. This also sets the number of digits shown in the displayed value when using the default handler for the #GtkScale::format-value signal.
Specifies whether the current value is displayed as a string next to the slider.
If @has_origin is set to %TRUE (the default), the scale will highlight the part of the scale between the origin (bottom or left side) of the scale and the current value.
Sets the position in which the current value is displayed.
Signal which allows you to change how the scale value is displayed. Connect a signal handler which returns an allocated string representing @value. That string will then be used to display the scale's value.
The #GtkHScale widget is used to allow the user to select a value using a horizontal slider. To create one, use gtk_hscale_new_with_range().
The position to show the current value, and the number of decimal places shown can be set using the parent #GtkScale class’s functions.
GtkHScale has been deprecated, use #GtkScale instead.
