* System.Windows.Forms
System.Windows.Forms eventually will support multiple
toolkits. Ximian will be delivering a product that will allow
for System.Windows.Forms applications to integrate with GNOME
through Gtk and MacOS X using Cocoa.
There are no current plans to support embedded devices, but
Gtk/FrameBuffer is an option. If you have suggestions or
recommendations, please let us <a
href="mailto:mono-hackers-list@ximian.com">let us know</a>
* Contributing
Currently Ximian developers are busy making our JIT engine
feature complete, and dealing with the low-level details of
the Mono runtime.
If you are interested in contributing, you can start stubbing
out classes and providing enumerations. That will help us
significantly when we start working on the actual bindings.
Christian Meyer is currently organizing this effort.
* System.Drawing
Using existing libraries to implement some of the functionality required
<ul>
* gdk-pixbuf is a generic image loader that loads an image
and leaves it into an RGB buffer. It hides all the details
about what image file format is being loaded.
* Libart is a general framework for rendering RGB/RGBA
buffers into RGB buffers and rendering postscript-like paths into
RGB/RGBA buffers.
</ul>
We want to use gdk-pixbuf as the image loader for the image
classes, and then we need operations to render that into the
windowing system (Gtk+, MacOS, etc). But notice how there is
very little dependnecies in Gdk-pixbuf on gtk, and libart has
none.
They are pretty independent from a windowing system
(gdk-pixbuf comes with some "helper" routines for rendering
data into a pixmap and to load pixmaps into RGB buffers).
A few things to keep in mind:
<ul>
* gdk-pixbuf can be used to load images for Gtk+,
MacOS X and Windows, it should be pretty portable,
although we might need in the future to back-port
some new features from Gtk head.
* Libart is probably only going to be used with X11,
as the MacOS X provides the same features in Quartz,
and Win32 *probably* has that in GDI+. If not, we
should use libart in Win32 as well (or for older
Windows systems).
</ul>
* Directory Layout
System.Drawing (assembly directory)
System.Drawing.Blah
Common code for "Blah"
Stubs for "Blah" to ease ports.
Gtk
System.Drawing.Blah.
Gtk ports of "System.Drawing.Blah"
MacOS
System.Drawing.Blah
MacOS ports of "System.Drawing.Blah"
Win32
System.Drawing.Blah
Win32 ports of "System.Drawing.Blah"
Then we use nant targets to include/exclude the right set of
files to create the assembly.
* Open questions:
I believe that the graphics contexts that are used to render
can accept either libart-like rendering operations and
X11-like rendering operations. This complicates matters, but
I am not sure. Someone needs to investigate this.
