javafx.scene.text.TextBoundsType

All Implemented Interfaces:

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

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

Specifies the behaviour of bounds reporting by Text nodes. The setting affects layoutBounds, boundsInLocal and boundsInParent The geometry of text can be measured either in terms of the bounds of the particular text to be rendered - visual bounds, or as properties of the font and the characters to be rendered - logical bounds. Visual bounds are more useful for positioning text as graphics, and for obtaining tight enclosing bounds around the text.

Logical bounds are important for laying out text relative to other text and other components, particularly those which also contain text. The bounds isn't specific to the text being rendered, and so will report heights which account for the potential ascent and descent of text using the font at its specified size. Also leading and trailing spaces are part of the logical advance width of the text.

Enum Constant Detail

LOGICAL

public static final TextBoundsType LOGICAL

Use logical bounds as the basis for calculating the bounds.

Note: This is usually the fastest option.

VISUAL

public static final TextBoundsType VISUAL

Use visual bounds as the basis for calculating the bounds.

Note: This is likely to be slower than using logical bounds.

Method Detail

values

public static TextBoundsType[] 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 (TextBoundsType c : TextBoundsType.values())
    System.out.println(c);

Returns:

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

valueOf

public static TextBoundsType 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
