Hi
I was thinking of writing a GUI toolkit from scratch using a basic '2D
library'. I have already come across the Widget Construction Kit.
My main question is: Could I build a GUI toolkit of reasonable
performance with the Widget Construction Kit, would it still feel more
or less lightweight? By reasonable I mean that the user wouldn't think
of the interface as being slow or unresponsive.
I've also thought of using pyglet to build widgets with, but this would
seem to be overkill. As a side question: by using opengl, the work would
be delegated to the GPU rather than the CPU; is this always a good
thing, or does it have downsides as well (performance, power usage, ...)?
Are there any other libraries that may be of interest to me?
Thanks in advance
It probably depends on how low level you want to go, I have pondered
about the possibility myself to have an all python(ic) gui toolkit,
capable of writing a (x11) windowing manager itself with.
But I decided that using tkinter and just live with its rough corners is
more bang for the buck for me than to reimplement tkinter badly.
Rather than writing a windowing toolkit from the low-level, I would
rather like to see some wrapper for existing windowing toolkit which
uses more pythonic idioms.
Most popular python GUI toolkit currently in use are only a simple thin
wrapper over the library they're wrapping and exposes a lot of the
design considerations of the language that the toolkit was originally
written in. Yes, even Tkinter that comes with the standard lib is a hack
on top of python and looks much more Tcl-ish than pythonic.
I have always had the idea of writing a windowing toolkit wrapper that
creatively uses python features for maximum expressiveness (e.g.
decorator, with-statement, for-each), but never got the time to write
anything like that.
When (or if) I'd finish this low-level gui toolkit, I'd incorporate it
into my original plans, which were: writing a library that provides the
programmer with 1 API, yet can display the GUI in a terminal (curses),
on the desktop(X/win32/...) or in your web browser (DHTML). Terminal
support would likely be very limited though.
I think I'll go ahead and try to write a wrapper around pyglet and start
writing some basic widgets.
