And with it, remove any notion of colormaps from GdkWindow. In particular, X11 windows will now not set attrs.colormap when calling XCreateWindow.

Functions for drawing points, lines, arcs, and text

<para>
|
|
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.

</para>
|
|
<para>
|
|
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
|
|
<link linkend="gdk-Graphics-Contexts">Graphics Contexts</link> section for
|
|
more information.

</para>
|
|
<para id="pango-data-structures">
|
|
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 gtk_widget_create_pango_context() or
|
|
gtk_widget_create_pango_layout().
