public class Context

extends Object

The internal state used by Pango when rendering.

This is one of those cases where we are unfortunate that the class name collides with the same name from another package and you could find yourself using both in the same file. If you're working from a Layout and need to use this, and given theses:

 import org.freedesktop.cairo.Context;
 import org.freedesktop.cairo.FontOptions;
 import org.gnome.pango.Layout;
 import org.gnome.gtk.Widget;

etc, you might be well off to do something like this in a Widget.ExposeEvent:

 final Context cr;
 final Layout layout;
 final FontOptions config;
 
 layout = new Layout(cr);
 config = new FontOptions();
 ...
 
 layout.getContext().setFontOptions(config);

which avoids you having to use the fully qualified org.gnome.pango.Context name when you call Layout's getContext().

You ordinarily do not need to use this, although you might want to know that every time a Pango Layout is created a fresh Pango Context is done up.
