The VScale
widget is used to allow the user to select a value using
a vertical slider. To create one, use hScaleNewWithRange
.
The position to show the current value, and the number of decimal places
shown can be set using the parent Scale
class’s functions.
GtkVScale has been deprecated, use Scale
instead.
- newtype VScale = VScale (ManagedPtr VScale)
- class GObject o => IsVScale o

- noVScale :: Maybe VScale

Exported types
Memory-managed wrapper type.
Methods
new
:: (HasCallStack, MonadIO m, IsAdjustment a) | |
=> a |
|
-> m VScale | Returns: a new |
Deprecated: (Since version 3.2)Use scaleNew
with OrientationVertical
instead
Creates a new VScale
.
newWithRange
:: (HasCallStack, MonadIO m) | |
=> Double |
|
-> Double |
|
-> Double |
|
-> m VScale | Returns: a new |
Deprecated: (Since version 3.2)Use scaleNewWithRange
with OrientationVertical
instead
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 scaleSetDigits
to correct it.
