Dir structure for ports
|
|
=======================
|
|
|
|
The directory structure here is:
|
|
|
|
gdk/
|
|
gdk/x11
|
|
gdk/win32
|
|
...
|
|
|
|
The gdk/ directory directly contains all public
|
|
header files (that are not specific to one
|
|
windowing system).
|
|
|
|
There, in general should be no system dependency
|
|
|
|
For each set of functionality, there are the following
|
|
files:
|
|
|
|
gdkwindow.h: public header file
|
|
gdkwindow.c: common implementation
|
|
x11/gdkwindow.i: functionality specific to X11
|
|
win32/gdkwindow.i: functionality specific to win32
|
|
|
|
The gdkwindow.c file looks like:
|
|
|
|
====
|
|
#include "gdkwindow.h"
|
|
|
|
#ifdef GDK_WINDOWING_X11
|
|
#include "x11/gdkwindow.i"
|
|
#elif defined(GDK_WINDOW_WIN32)
|
|
#include "win32/gdkwindow.i"
|
|
fo#endif
|
|
|
|
[ generic implementation bits ]
|
|
====
|
|
|
|
x11/gdkwindow.i should only assume that gdkwindow.h has been
|
|
included and included all other dependencies explicitely.
|
|
|
|
The x11/ directory will contain:
|
|
|
|
.i files
|
|
.c files specific to X
|
|
.h files specific to X
|
|
|
|
And a Makefile.am that takes care of distributing the
|
|
files in the directory, and also for building any
|
|
X-specific utilities. (Such as the gxid daemon).
|
|
|
|
|
|
Virtualization
|
|
==============
|
|
|
|
The concept of virtualization is that calls to draw
|
|
on a drawable are dispatched through a function table.
|
|
This potentially allows for:
|
|
|
|
Postscript drawables
|
|
metafiles
|
|
|
|
It also provides a nice clean framework for multi-windowing
|
|
support - instead of reimplementing a whole bunch of function
|
|
calls, one provides an implementaiton for the vtables.
|
|
|
|
X works in this way internally - per-screen functions are
|
|
virtualized inside a screen structure, and drawing functions
|
|
are virtualized inside the GC structure.
|
|
|
|
For the virtualization of drawing, clearly GdkDrawable needs
|
|
to be virtualized. Beyond that, one has to decide on
|
|
a case-by-case basis whether a particular structure is
|
|
drawing-mode independent (like GdkRectangle) or not.
|
|
|
|
The most important GDK structures that are involved drawing are:
|
|
|
|
GdkColor
|
|
GdkGC
|
|
GdkFont
|
|
GdkRegion
|
|
|
|
The whole font aspect of Gdk is going to get heavily
|
|
reworked with the introduction of "Pango".
|
|
GdkRegion almost certainly needs to be virtualized,
|
|
if you, way, want to do postscript drawables.
|
|
|
|
While doing so, the API of GdkRegion should be
|
|
changed so that the region operations take 3 parameters
|
|
instead of returning a newly created region.
|
|
|
|
|
|
Drawable operations:
|
|
destroy
|
|
create_gc
|
|
get_values
|
|
set_values
|
|
set_dashes
|
|
copy
|
|
|
|
GC Operations:
|
|
draw_point
|
|
draw_line
|
|
draw_rectangle
|
|
draw_arc
|
|
draw_polygon
|
|
draw_string
|
|
draw_text
|
|
draw_text_wc
|
|
draw_pixmap
|
|
draw_bitmap
|
|
draw_image
|
|
draw_points
|
|
draw_segments
|
|
draw_lines
|
|
|
|
|
|
Adding multi-screen, display support.
