Constructor Detail

Context

public Context(Handle handle)

Create a new Context passing a handle that was created in the native layer. This is an internal method that should only be used by Java-Gnome.

Parameters: handle The handle to a native resource.

Method Detail

getBaseDir

public Direction getBaseDir()

Retrieves the base direction for the context.

getContextFromHandle

public static Context getContextFromHandle(Handle handle)

Static factory method that should only be used interally by Java-Gnome.

getFontDescription

public FontDescription getFontDescription()

Retrieve the default font description for the context.

Returns: default font description.

getLanguage

public Language getLanguage()

Retrieves the global language tag for the context.

getMetrics

public FontMetrics getMetrics(FontDescription desc, Language language)

Get overall metric information for a font particular font description. Since the metrics may be substantially different for different scripts, a language tag can be provided to indicate that the metrics should be retrieved that correspond to the script(s) used by that language.

The PangoFontDescription is interpreted in the same way as by pango_itemize(), and the family name may be a comma separated list of figures. If characters from multiple of these families would be used to render the string, then the returned fonts would be a composite of the metrics for the fonts loaded for the individual families.

listFamilies

public FontFamily[] listFamilies()

List all families for a Context.

loadFont

public FontDescription loadFont(FontDescription desc)

Loads the font in one of the fontmaps in the context that is the closest match for desc.

Parameters: desc A FontDescription describing the font to load

Returns: The font loaded, or null if no font matched.
