Re: [Maya-Python] Display QQmlApplicationEngine

[Ruchit Bhatt]

I did few test with QQMLAPPLICATIONENGINE outside Maya & everything works fine. 
Problem with Maya is, If I use
app = QApplication(sys.argv)

Maya give a error
# Error: RuntimeError: A QApplication instance already exists. #

I have no idea how to show QQmlApplicationEngine window in Maya..Many people 
use QQuickView.show() but I found QQmlApplicationEngine is more powerful than 
QQuickView.

[Maya-Python] Display QQmlApplicationEngine

[Ruchit Bhatt]

How to run & display QQmlApplicationEngine in Maya using PySide2?
Here is my code

class Ball(QObject):
def __init__(self):
QObject.__init__(self)

@Slot(int) 
def add(arg1):
mc.polySphere(r=arg1)


engine = QQmlApplicationEngine()
ball = Ball()
engine.rootContext().setContextProperty("ball", ball)
engine.load(QUrl.fromLocalFile("E:/code/QML/sphere.qml"))

I tried your example & its working fine. Thanks

*In script Editor*

mayapy_path = r'C:/Program Files/Autodesk/Maya201x/bin/mayapy.exe'
script_path = r'E:/multi_test.py'

proc_obj = subprocess.Popen(mayapy_path + ' ' + script_path + ' -po', stdin=
subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
result = cPickle.load(proc_obj.stdout)
print result

*multi_test.py*
import multiprocessing
from time import time
import cPickle
import sys

## Simple func to eat up cpu power.
def whileFunc(z):
while z < 10:
z += 1 
return z

if __name__ == "__main__":
## Get current time 
currtime = time()

## How often to run (just a test value)
N = 1
## Just a list with 1s 
myList = [1]*N

nrOfProcessors = multiprocessing.cpu_count() 

## Set our pool of processors 
po = multiprocessing.Pool(nrOfProcessors)

## create the threads 
res = po.map_async(whileFunc, myList)

## If we pass a -po flag, pickle the output and write it out
if '-po' in sys.argv[1:]:
results = len(res.get())
cPickle.dump(results, sys.stdout, -1)
sys.stdout.flush()
sys.exit(0)

print 'This value below should be a 1000:'
print len(res.get())
print 'time elapsed:', time() - currtime

[Maya-Python] Multiprocessing Returns New Maya Instance

[Ruchit Bhatt]

Hi,
I tried multiprocessing module in maya python with basic example and every 
time it returns new maya instance plus 

object of multiprocessing.Queue() returns nothing on object.get()
is python interpreter is not a separate process in Maya ?
please share efficient example on how to deal with multiprocessing in Maya.
Thank you

[Maya-Python] MayaPy Cython Import Error

[Ruchit Bhatt]

Hi,
How to convert python module to *.pyd using cython ?

I am using Maya 2017 Up 4, And in that i installed cython with below step

> C:\Program Files\Autodesk\Maya2017\bin>mayapy ez_setup.py
> C:\Program Files\Autodesk\Maya2017\bin>mayapy get-pip.py
> C:\Program Files\Autodesk\Maya2017\Python\Scripts>pip install setuptools 
> --upgrade
> C:\Program Files\Autodesk\Maya2017\Python\Scripts>pip install cython
>
>
After that i followed this link Hello Cython in Maya 



*Setup.py*

  ]

*Terminal Error*



*But works fine in script editor*



So how to compile *.py to *.pyd for maya  and make a use in scriptEditor ?

@Mahendra Gangaiwar
Thnx
dict((w.objectName(), w) for w in QtWidgets.QApplication.allWidgets())
dict((w.objectName(), w) for w in QtWidgets.QApplication.allWindows())


is super useful to get objectName of all instance.But


mm.eval('GraphEditor')
 Ge = QtWidgets.QApplication.activeWindow()
 print Ge.windowTitle()
 Ge.setWindowOpacity(0.5)


This is still not working  (print Ge.windowTitle()   #Result Script Editor)




Let's take one more example, in ReferenceEditor if i want to select 
*item02*(i.e 
Test03RN Test03.ma) & *item03*(i.e Test04RN Test04.ma)  inside 
*refEdEditorPane. 
*How can i do that via PySide  ??


*Before*
























*After*

[Maya-Python] Re: Access Maya UI in Qt way using Python API

[Ruchit Bhatt]

See this basic test

import maya.cmds as mc
import maya.mel as mm
import maya.OpenMayaUI as omUI
from PySide import QtGui, QtCore
from shiboken import wrapInstance

mm.eval('GraphEditor')


def getGraphEdtr():
graphEdtrPtr = omUI.MQtUtil.findLayout(
"graphEditor1Window|TearOffPane|graphEditor1")
return wrapInstance(long(graphEdtrPtr), QtGui.QWidget)

graphEdtr = getGraphEdtr()
graphEdtr.setWindowOpacity(0.4)


No idea why its not working

[Ruchit Bhatt]

@Simon 
I know how PyQt/Pyside works, What i want to know is "How to modify 
pre-exist Maya UI element ?".

*Add custom action in QMenu of nodeEditor, GraphEditor,etc.
*Trigger QDialog on middle click to any node inside node editor.
*Set X & Y position of selected node inside node editor.
*Custom drop down menu in shelf.
*Modify font style in outliner.

Justin, QListWidget.setItemWidget is indeed useful. Thank you for pointing

On a different thought, i would still like to implement a modelView based

idx = self.sourceModel().index(srcRow, 0, srcParent)
filePath = self.sourceModel().filePath(idx)
if os.path.isfile(filePath):
print filePath

Issue with above function is, 
it returns same value multiple times and to print  all files you will need 
to expand all

Instead of

for exc in self._excludes: 
if name.endswith(exc):

Below one is simple & perfect in my case, wht do you think ??
fileType = self.sourceModel().fileInfo(idx).suffix()
for exc in self._excludes: 
if exc == fileType:
return False

Hi,
In PyQt/PySide how can i make spherical joystick kind of button ?? like 
zbrush light direction UI
I have polygon arrow model at origin, And i want to control direction of 
arrow using this kind of button.

I think Spherical Coordinates system will be useful to create this.
i.e
x=ρsinϕcosθ
(8)
y=ρsinϕsinθ
(9)
z=ρcosϕ

ρ=x2+y2+z2−−√
(11)
tanθ=yx
(12)
cosϕ=zx2+y2+z2−−√














Give me your inputs
Thank you
