Enum DerivedScaleType

java.lang.Object

java.lang.Enum<DerivedScaleType>

com.intellij.ui.scale.DerivedScaleType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<DerivedScaleType>

public enum DerivedScaleType
extends java.lang.Enum<DerivedScaleType>

The scale factors derived from the ScaleType scale factors. Used for convenience.

Enum Constant Summary

Enum Constants

Enum Constant and Description
DEV_SCALE The device scale factor.
EFF_USR_SCALE The effective user scale factor "combines" all the user space scale factors which are: USR_SCALE and OBJ_SCALE.
PIX_SCALE The pixel scale factor "combines" all the other scale factors (user, system and object) and defines the effective scale of a particular UI object.

Method Summary

Modifier and Type	Method and Description
static DerivedScaleType	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static DerivedScaleType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

EFF_USR_SCALE

public static final DerivedScaleType EFF_USR_SCALE

The effective user scale factor "combines" all the user space scale factors which are: USR_SCALE and OBJ_SCALE. So, basically it equals USR_SCALE * OBJ_SCALE.

DEV_SCALE

public static final DerivedScaleType DEV_SCALE

The device scale factor. In JRE-HiDPI mode equals ScaleType.SYS_SCALE, in IDE-HiDPI mode equals 1.0 (in IDE-HiDPI the user space and the device space are equal and so the transform b/w the spaces is 1.0)

PIX_SCALE

public static final DerivedScaleType PIX_SCALE

The pixel scale factor "combines" all the other scale factors (user, system and object) and defines the effective scale of a particular UI object.

For instance, on Mac Retina monitor (JRE-managed HiDPI) in the Presentation mode (which, say, doubles the UI scale) the pixel scale would equal 4.0 (provided the object scale is 1.0). The value is the product of the user scale 2.0 and the system scale 2.0. In the IDE-managed HiDPI mode, the pixel scale equals EFF_USR_SCALE.

Method Detail

values

public static DerivedScaleType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DerivedScaleType c : DerivedScaleType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DerivedScaleType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
