Class Font

public Font(double size)

Constructs a font using the default face "System". The underlying font used is determined by the implementation based on the typical UI font for the current UI environment.

public Font(String name, double size)

Constructs a font using the specified full face name and size

public static Font getDefault()

Gets the default font which will be from the family "System", and typically the style "Regular", and be of a size consistent with the user's desktop environment, to the extent that can be determined.

public static List<String> getFamilies()

Gets all the font families installed on the user's system, including any application fonts or SDK fonts. This call has performance considerations as looking up all of the fonts may be an expensive operation the first time.

public static List<String> getFontNames()

Gets the names of all fonts that are installed on the users system, including any application fonts and SDK fonts. This call has performance considerations as looking up all of the fonts may be an expensive operation the first time.

public static List<String> getFontNames(String family)

Gets the names of all fonts in the specified font family that are installed on the users system, including any application fonts and SDK fonts. This call has performance considerations as looking up all of the fonts may be an expensive operation the first time.

public static Font font(String family, FontWeight weight, FontPosture posture, double size)

Searches for an appropriate font based on the font family name and weight and posture style. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements.

A null or empty value for family allows the implementation to select any suitable font.

public static Font font(String family, FontWeight weight, double size)

Searches for an appropriate font based on the font family name and weight style. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements. A null or empty value for family allows the implementation to select any suitable font.

public static Font font(String family, FontPosture posture, double size)

Searches for an appropriate font based on the font family name and posture style. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements. A null or empty value for family allows the implementation to select any suitable font.

public static Font font(String family, double size)

Searches for an appropriate font based on the font family name and size. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements. A null or empty value for family allows the implementation to select any suitable font.

public static Font font(String family)

Searches for an appropriate font based on the given font family name and default font size. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements. A null or empty value for family allows the implementation to select any suitable font.

public static Font font(double size)

Searches for an appropriate font based on the default font family name and given font size. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements.

public final String getName()

The full font name. This name includes both the family name and the style variant within that family. For example, for a plain Arial font this would be "Arial Regular" and for a bolded Arial font this would be "Arial Bold". The precise name to use when loading a font is defined within each font file as the full font name. For example, "Proxima Nova ExtraCondensed Bold Italic" would refer to a specific Proxima Nova font. A null or empty name allows the implementation to select any suitable font.

There is a single unified way to load all of application supplied (via Font.loadFont(), JavaFX runtime delivered fonts, and system installed fonts. Simply create the font by specifying the full name of the font you want to load. If the specific font cannot be located, then a fallback or default font will be used. The "name" will be updated to reflect the actual name of the font being used. A load failure condition can be discovered by checking the name of the Font with the name you tried to load.

Note that if you wish to locate a font by font family and style then you can use one of the font(java.lang.String, javafx.scene.text.FontWeight, javafx.scene.text.FontPosture, double) factory methods defined in this class.

public final String getFamily()

Returns the family of this font.

public final String getStyle()

The font specified string describing the style within the font family.

public final double getSize()

The point size for this font. This may be a fractional value such as 11.5. If the specified value is < 0 the default size will be used.

public static Font loadFont(String urlStr, double size)

Loads a font resource from the specified URL. If the load is successful such that the location is readable, and it represents a supported font format then a Font object will be returned.

If a security manager is present, the application must have both permission to read from the specified URL location and the FXPermission "loadFont". If the application does not have permission to read from the specified URL location, then null is returned. If the application does not have the "loadFont" permission then this method will return the default system font with the specified font size.

Any failure such as a malformed URL being unable to locate or read from the resource, or if it doesn't represent a font, will result in a null return. It is the application's responsibility to check this before use.

On a successful (non-null) return the font will be registered with the FX graphics system for creation by available constructors and factory methods, and the application should use it in this manner rather than calling this method again, which would repeat the overhead of downloading and installing the font.

The font size parameter is a convenience so that in typical usage the application can directly use the returned (non-null) font rather than needing to create one via a constructor. Invalid sizes are those <=0 and will result in a default size.

If the URL represents a local disk file, then no copying is performed and the font file is required to persist for the lifetime of the application. Updating the file in any manner will result in unspecified and likely undesired behaviours.

public static Font[] loadFonts(String urlStr, double size)

Loads font resources from the specified URL. If the load is successful such that the location is readable, and it represents a supported font format then an array of Font will be returned.

The use case for this method is for loading all fonts from a TrueType Collection (TTC).

If a security manager is present, the application must have both permission to read from the specified URL location and the FXPermission "loadFont". If the application does not have permission to read from the specified URL location, then null is returned. If the application does not have the "loadFont" permission then this method will return an array of one element which is the default system font with the specified font size.

Any failure such as a malformed URL being unable to locate or read from the resource, or if it doesn't represent a font, will result in a null return. It is the application's responsibility to check this before use.

On a successful (non-null) return the fonts will be registered with the FX graphics system for creation by available constructors and factory methods, and the application should use it in this manner rather than calling this method again, which would repeat the overhead of downloading and installing the fonts.

public static Font loadFont(InputStream in, double size)

Loads a font resource from the specified input stream. If the load is successful such that the stream can be fully read, and it represents a supported font format then a Font object will be returned.

If a security manager is present, the application must have the FXPermission "loadFont". If the application does not have permission then this method will return the default system font with the specified font size.

Any failure such as abbreviated input, or an unsupported font format will result in a null return. It is the application's responsibility to check this before use.

On a successful (non-null) return the font will be registered with the FX graphics system for creation by available constructors and factory methods, and the application should use it in this manner rather than calling this method again, which would repeat the overhead of re-reading and installing the font.

The font size parameter is a convenience so that in typical usage the application can directly use the returned (non-null) font rather than needing to create one via a constructor. Invalid sizes are those <=0 and will result in a default size.

This method does not close the input stream.

public static Font[] loadFonts(InputStream in, double size)

Loads font resources from the specified input stream. If the load is successful such that the stream can be fully read, and it represents a supported font format then an array of Font will be returned.

public String toString()

Converts this Font object to a String representation. The String representation is for informational use only and will change. Do not use this string representation for any programmatic purpose.

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

public int hashCode()

Returns a hash code for this Font object.
