Found a very nice, small, cross-platform GUI toolkit for Python.

[laplacian42]

I think I just found the GUI toolkit for Python I've been searching
for. It seems to meet all of the following requirements:

  * free software
  * small (I don't need batteries -- Python already comes with those.)
  * easy to use
  * actively maintained
  * cross-platform
  * easy to install
  * based on a stable and actively-maintained C library
  * does not depend on an external scripting language (for example,
Tcl)
  * well-documented
  * not too many dependencies
  * can easily integrate with PyOpenGL
  * support for accessibility

and it's also written in Python.

I have no idea how it's stayed under the radar in the Python community
for this long, yet here it is: [OcempGUI](http://ocemp.sourceforge.net/
gui.html). The C library it depends upon? [SDL](http://
www.libsdl.org/) (via [PyGame](http://www.pygame.org/news.html)).

The sf project page is .

Installation only requires getting SDL installed, then PyGame, and
then a `sudo python setup.py install` for OcempGUI. `cd` into its `doc/
examples` directory and run a few of the examples (ex. `python
hello_world.py`).

The part of [the manual](http://ocemp.sourceforge.net/manual/ocempgui-
manual.html) that seems most like a beginner tutorial is .

Note: spelling is "OcempGUI". Also, since google broke some of the
links,
here's that main link again:

Well, to be fair, SDL is pretty commonly-used software and they offer
binary downloads for Mac OS X and MS Windows. Pygame seems to provide
the same. So, installation should be a breeze.

Well, of course, there *is* a dependency: you need Tcl/Tk installed.

I suppose so, but the point of my post was that by default it makes
quite a nice GUI toolkit.

What? Qt and wX are *huge* compared to OcempGUI.

Probably, but wX and Qt are written in C++. OcempGUI is pure Python,
which would make it easier for the Python community to help extend,
optimize, and maintain.

OcempGUI can also be "themed" as well. Though I'm not sure how much is
out there yet.

Well, yes. KDE users will already have Qt installed (and maybe PyQt)
but may groan at the prospect of having to install GTK+ and PyGTK.
Gnome users will already have GTK+ installed (and maybe PyGTK), but
may groan at having to install Qt and PyQt. However, both will likely
have no qualms about installing SDL and Pygame (which are pretty small
and also allow them to play various games as well).

There is a `window.py` example that comes with the distribution. It
has modal and non-modal windows within the main window.

I haven't yet seen any examples where OcempGUI runs full-screen.

The relevant portion of the manual re. subwindows is:

Funny you should mention this. I'd just been getting it installed on a
Mac I have access to. Here's what it took:

1. Install a Python from python.org. Something about the Pygame
installer not wanting to use the system Python. Also, it wants v2.5.
Ok. (As an aside, that's about 19 MB.) This is a mpkg file in a dmg,
so the install is trivial.

2. Now SDL. This one is just a drag-and-drop to your `/Library/
Frameworks` folder. Easy, but the user will have to look into the
README to know what to do. (1 MB)

3. Now PyObjC. Another mpkg file. It's available at the pygame site.
(6 MB)

4. Pygame. An mpkg in a zip file. (9 MB)

5. Whoops. Surprise. NumPy is required. mpkg in a dmg. (3 MB)

6. Finally, OcempGUI. This is a `sudo python setup.py install`. (4 MB)

That's 42 MB all told, admin rights required, and the examples are
running. Pretty neat.

> Thats a lot to ask of a user

[sigh] Probably. Unless maybe all the prereq's were gathered together
with a script to run through and install them all one after another.

Well, it will allow them to run *any* OcempGUI program thereafter, but
I see your point.

Just tried that. Didn't know it was all installed (Tcl/Tk too) and
ready to go. Wow that's pretty darn convenient.

Aye.
