Abstract base class for range-based controls.

Description

Range is a base class for Control nodes that change a floating-point value between a minimum and a maximum, using step and page, for example a ScrollBar.

Properties

bool	allow_greater	`false`
bool	allow_lesser	`false`
bool	exp_edit	`false`
float	max_value	`100.0`
float	min_value	`0.0`
float	page	`0.0`
float	ratio
bool	rounded	`false`
float	step	`1.0`
float	value	`0.0`

Methods

void	share ( Node with )
void	unshare ( )

Signals

changed ( )

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

value_changed ( float value )

Emitted when value changes.

Property Descriptions

bool allow_greater

Default	`false`
Setter	set_allow_greater(value)
Getter	is_greater_allowed()

If true, value may be greater than max_value.

bool allow_lesser

Default	`false`
Setter	set_allow_lesser(value)
Getter	is_lesser_allowed()

If true, value may be less than min_value.

bool exp_edit

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.

float max_value

Default	`100.0`
Setter	set_max(value)
Getter	get_max()

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

float min_value

Default	`0.0`
Setter	set_min(value)
Getter	get_min()

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

float page

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.

float ratio

Setter	set_as_ratio(value)
Getter	get_as_ratio()

The value mapped between 0 and 1.

bool rounded

Default	`false`
Setter	set_use_rounded_values(value)
Getter	is_using_rounded_values()

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

float step

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.

float value

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.
