If [code]true[/code] and [code]min_value[/code] is greater than 0, [code]value[/code] will be represented exponentially rather than linearly.

<member name="max_value" type="float" setter="set_max" getter="get_max">
|
|
Maximum value. Range is clamped if [code]value[/code] is greater than [code]max_value[/code]. Default value: 100.
|
|
</member>
|
|
<member name="min_value" type="float" setter="set_min" getter="get_min">
|
|
Minimum value. Range is clamped if [code]value[/code] is less than [code]min_value[/code]. Default value: 0.

</member>
|
|
<member name="page" type="float" setter="set_page" getter="get_page">
|
|
Page size. Used mainly for [ScrollBar]. ScrollBar's length is its size multiplied by [code]page[/code] over the difference between [code]min_value[/code] and [code]max_value[/code].

If greater than 0, [code]value[/code] will always be rounded to a multiple of [code]step[/code]. If [code]rounded[/code] is also [code]true[/code], [code]value[/code] will first be rounded to a multiple of [code]step[/code] then rounded to the nearest integer.
