A vertical slider widget for selecting a value from a range
The <gtk-vscale> widget is used to allow the user to select a value using
a vertical 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 <gtk-scale> class's functions.
<gtk-adjustment>) ⇒ (ret <gtk-widget>)Creates a new
<gtk-vscale>.

<gtk-adjustment>which sets the range of the scale.- ret

<gtk-vscale>.
double) (max double) (step double) ⇒ (ret <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-digitsto correct it.
- min
- minimum value
- max
- maximum value
- step
- step increment (tick size) used with keyboard shortcuts
- ret
