:cache-p

Specifies if this graphics context should be cached locally by CLX. If nil then the state is not cached, otherwise a local cache is kept.

:drawable

The drawable whose root and depth are to be associated with this graphics context. This is a required keyword argument.

:arc-mode, :background, :cap-style, :clip-mask, :clip-ordering, :clip-x, :clip-y, :dash-offset, :dashes, :exposures, :fill-rule, :fill-style, :font, :foreground, :function, :join-style, :line-style, :line-width, :plane-mask, :stipple, :subwindow-mode, :tile, :ts-x, :ts-y

Initial attribute values for the graphics context.

Creates, initializes, and returns a graphics context (gcontext). The graphics context can only be used with destination drawables having the same root and depth as the specified :drawable. If :cache-p is non-nil, the graphics context state is cached locally, and changing a component has no effect unless the new value differs from the cached value. Changes to a graphics context (setf and with-gcontext) are always deferred regardless of the cache mode and sent to the server only when required by a local operation or by an explicit call to force-gcontext-changes.

All of the graphics context components are set to the values that are specified by the keyword arguments, except that a value of nil causes the default value to be used. These default values are as follows:

Note that foreground and background do not default to any values that are likely to be useful on a color display. Since specifying a nil value means use the default, this implies for clip-mask that an empty rectangle sequence cannot be specified as an empty list; :none must be used instead. Specifying a stringable for font causes an implicit open-font call to occur.

gcontext

Type gcontext.
