Detailed Description

These functions provide support for drawing points, lines, arcs and text onto what are called 'drawables'. Drawables, as the name suggests, are things which support drawing onto them, and are either GdkWindow or GdkPixmap objects. Many of the drawing operations take a GdkGC argument, which represents a graphics context. This GdkGC contains a number of drawing attributes such as foreground color, background color and line width, and is used to reduce the number of arguments needed for each drawing operation. See the Graphics Contexts section for more information. Some of the drawing operations take Pango data structures like PangoContext, PangoLayout or PangoLayoutLine as arguments. If you're using GTK+, the ususal way to obtain these structures is via gtkWidgetCreatePangoContext or gtkWidgetCreatePangoLayout.
