Methods

void

share ( Node with )

unshare ( )

Signals

  • changed ( )

Emitted when min_value, max_value, page, or step change.


  • value_changed ( float value )

Emitted when value changes.

Property Descriptions

Default

false

Setter

set_allow_greater(value)

Getter

is_greater_allowed()

If true, value may be greater than max_value.


Default

false

Setter

set_allow_lesser(value)

Getter

is_lesser_allowed()

If true, value may be less than min_value.


Default

false

Setter

set_exp_ratio(value)

Getter

is_ratio_exp()

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


Default

100.0

Setter

set_max(value)

Getter

get_max()

Maximum value. Range is clamped if value is greater than max_value.


Default

0.0

Setter

set_min(value)

Getter

get_min()

Minimum value. Range is clamped if value is less than min_value.


Default

0.0

Setter

set_page(value)

Getter

get_page()

Page size. Used mainly for ScrollBar. ScrollBar’s length is its size multiplied by page over the difference between min_value and max_value.


Setter

set_as_ratio(value)

Getter

get_as_ratio()

The value mapped between 0 and 1.


Default

false

Setter

set_use_rounded_values(value)

Getter

is_using_rounded_values()

If true, value will always be rounded to the nearest integer.


Default

1.0

Setter

set_step(value)

Getter

get_step()

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


Default

0.0

Setter

set_value(value)

Getter

get_value()

Range’s current value.

Method Descriptions

  • void share ( Node with )

Binds two ranges together along with any ranges previously grouped with either of them. When any of range’s member variables change, it will share the new value with all other ranges in its group.


  • void unshare ( )

Stops range from sharing its member variables with any other.
