Ha, I remember that post!
Yet, I believe that the bottom line was that your approach was more robust and
faster,
hence I simply tried to do the same thing that you do in C++ in Python. Also, I
want to use it for a very time critical thing and that timer event gives me the
creeps :-)
Ultimately I wanted that it could be adapted and changed quickly without having
to write c++ code and compile anything, Linux was just an afterthought (we
don't use it, but since Alan asked I thought it was one more reason to give it
a try). It's cost me a day and I'm not getting anywhere, I don't even know how
to debug it, it just crashes hard and Visual Studio won't say a thing even when
it's connected to the XSI process.
Anyway, thanks for bringing it back up Steven.
I will probably take the C++ route and add my own bits and pieces where
required.

are you trying to make a pure python version of the plugin?
eric hulser at blur had a pure python version working using pyhook but it
was filled with various instabilities.
http://sourceforge.net/apps/mediawiki/pyhook/index.php?title=Main_Page
also, aloys has posted on the original PyQtForSoftimage thread talking
about ways to do it in pure python on linux.
For the linux afficionados out there, you can get very simple and pure
python implementation of PyQt in Softimage by just implementing a XSI Timer
event and running this code, which emulates the Qt event loop:
def ALUIHelpers_Events_onTimer_
OnEvent(ctx):
app = QtGui.QApplication.instance()
if app:
app.processEvents()
app.sendPostedEvents(None, QtCore.QEvent.DeferredDelete)
We found 20ms for the timer to be good enough for most UIs.
Lately, with the combination QOpenGL widgets and image players, we bumped
up to 5ms and using a C++ implementation.
We have been using PyQt inside Softimage/Maya for the last two years and
it's been great so far, it's good to see more people jumping on board and
sharing code!

Find attached a very basic test version I put together on Tuesday that
should just respond to mouse clicks by printing out which mouse button was
pressed (replace stevens dll with this one, restart softimage and in the
plugin manager right-click on the getQtSoftimageAnchor command of the
plugin and choose Invoke... from the popup menu.
Aaaaand...what you get is an instant fast exit to the desktop, and I'm
entirely clueless why.
I tried a couple of things (inlcuding using WH_MOUSE_LL instead of
WH_MOUSE in line 110, which at least doesn't crash but simply does nothing
else either).
I get the same result using the "listenerKeyboard" procedure starting at
line 93, btw.
If ne1 with more indepth knowledge of win32api, ctypes, mouse and keyboard
hooks wants to take a closer look please be my guest, it would be cool to
get this running and not having to compile anything for each new version of
QT, PySide or Softimage, including hope for a working Linux version. Any
hints are highly welcome too.
Of course, there's also a good chance that this can never work due to
architectural restrictions (e.g. the way Python is talking to Softimage),
but what do I know.
Any ideas?
