Subject: [Maya-Python] In 2014, mayapy errors on exit if sceneAssembly plugin
loaded
Thought I should let other people know about this, in case they were
experiencing similar problems: we noticed that, when using 2014's mayapy
interpreter, it would always segfault when exiting.
We tracked the issue down to a particular plugin, the sceneAssembly plugin. If
this plugin is not loaded, mayapy will exit cleanly.
We reported this to Autodesk, and they suggested using os._exit...
unfortunately, this would require us to modify every single mayapy script we
have (including any mayapy -c uses), wrap them to catch SystemExit
exceptions, and instead us os._exit. Plus, python would no longer do it's
normal cleanup (ie, output buffers wouldn't be flushed, and os-level resources
like file handles might not get released, etc).
So, it seems much easier to just not use sceneAssembly. The only trick here is
that simply unloading it won't work - if the plugin was EVER loaded, mayapy
will still crash on exit - and maya will by default set this plugin to
autoload.
To work around this, you can disable the setting of sceneAssembly to autoload
for new users by sticking this somewhere in your site's maya startup (mel) code:
optionVar -iv oneTimeDefaultPluginLoad2013Update 1;
For users which already have started 2014 at least once, it will have already
been set to autoload; so the next time maya starts up, the plugin will load,
but you can prevent it from loading again by putting in code like this:
# check for and disable autoload of sceneAssembly plugin - will cause
# mayapy to exit with an error if loaded... get rid of this if they fix
# this bug...
if pm.versions.current() = pm.versions.v2014:
def sceneAssemblyDisable():
if pm.pluginInfo('sceneAssembly', q=1, loaded=1):
pm.pluginInfo('sceneAssembly', e=1, autoload=False)
# do this on selection changed, because need a way to delay this
# so we KNOW it's after the plugins have loaded. executeDeferred
# and idleEvent both were too early...
pm.scriptJob(event=('SelectionChanged', sceneAssemblyDisable),
runOnce=True)
(The reasoning for this somewhat strange logic is that, when userSetup.py runs,
autoloaded plugins haven't been loaded yet. This would seem to be ideal, except
that it seems to only way to turn OFF autoloading is AFTER the plugin has
actually been loaded. Nor can you even check to see if it WOULD be autoloaded.
So... we need a way to stall until AFTER all auto-loaded plugins have been
loaded, check if the plugin WAS loaded, and if so, turn off it's autoload from
then on...)

[Maya-Python] Closing PySide windows in Maya
Hey All, I'm getting an issue whereby my PySide windows are not being properly destroyed when they're closed. code import pymel.core as pm from PySide.QtCore import * from PySide.QtGui import * import shiboken import maya.OpenMayaUI as mui def getMayaWindow(): ptr = mui.MQtUtil.mainWindow() return shiboken.wrapInstance(long(ptr), QWidget) class testWindow( QMainWindow ) : def __init__ ( self, parent=getMayaWindow() ) : QMainWindow.__init__( self, parent=parent ) self.setObjectName(testWindow) self.layout = QHBoxLayout() self.label = QLabel(test panel) self.layout.addWidget(self.label) self.setLayout(self.layout) window = testWindow() window.show() /code Run the code above a couple of times, and close the window each time. Now run this : code from PySide.QtCore import * from PySide.QtGui import * import shiboken import pymel.core as pm import maya.OpenMayaUI as mui def getMayaWindow(): ptr = mui.MQtUtil.mainWindow() return shiboken.wrapInstance(long(ptr), QWidget) for child in getMayaWindow().children() : objName = child.objectName() if objName == : print -+str(child) else : print - + objName print len(getMayaWindow().children()) /code Notice that there are multiple instances of the window still there. The only way I can currently clean it up is to add this to the QMainWindow class : code def closeEvent( self, event ) : QMainWindow.closeEvent( self, event ) shiboken.delete(self) /code However, some of my dynamic UI's cause a crash with this override, and it feels a little heavy handed to have to override the closeEvent. Has anyone else hit this issue? Mike -- You received this message because you are subscribed to the Google Groups Python Programming for Autodesk Maya group.

Re: [Maya-Python] Closing PySide windows in Maya
Hi Mike, I ran into the same problem and the easiest way I came up with was just by forcing the window to be destroyed every time the script ran. Just like you would do in the old days with mel :) if pm.window( 'testWindow', query = True, exists = True ) : pm.deleteUI( 'testWindow' ) So add those lines to your script and that deletes the old window.

Re: [Maya-Python] Closing PySide windows in Maya
Oh you can also add a check for visibility so it doesn't destroy any windows that are still in the users view. i.e. if pm.window( 'testWindow', query = True, exists = True ) : print 'exists' if not pm.window( 'testWindow', query = True, visible = True ) : print 'not visible' pm.deleteUI( 'testWindow' ) 2013/7/10 Jan: jan@gmail.com Hi Mike, I ran into the same problem and the easiest way I came up with was just by forcing the window to be destroyed every time the script ran.

[Maya-Python] Getting the main file menu in modern days
Hi there
I use this to get the Maya file menu and start populating it with various
things:
import maya.cmds as cmds
from pymel.core import menuItem,melGlobals
from maya.mel import eval as melcommand
gMainFileMenu=cmds.menu(melGlobals['$gMainFileMenu'],q=1,postMenuCommand=1)
melcommand('string $fileMenuRefreshCmd = `menu -q -postMenuCommand
$gMainFileMenu`')
melcommand('eval($fileMenuRefreshCmd)')
defaultMenuItems=cmds.menu(melGlobals['$gMainFileMenu'],q=1,ia=True)
It's embarrassing to admit, but in my defense it just works and I've been
copy pasting this example into my code for years. Finally figured to step into
modern days and figure out how to do this using a little bit friendlier
syntax...
Problem being I have no idea how to do that and am still sat with this
Frankenstein code I wrote dragging along with me.
Can someone please translate this for me into a more syntax and sharable
friendly way or point me at a good page to read up on this?
Thanks in advance.
