Getting list of camera or render globals from maya scene file

[eric-thelander]

I want to call readMayaFile.py from my GUI made in PyQt4 and readMayaFile.py contaains a method getCams that returns list of cam in the maya scene file supplied..

here is what I have in the readMayaFile.py

readMayaFile.py

import os
import maya.standalone
import maya.cmds as cmds
##fileToOpen="I:/scenes/san_telus_pan_v009.ma"
def getCams(phileToOpen):
    maya.standalone.initialize(name='python')
    cmds.file(phileToOpen, force=True,open=True)
    cams=cmds.ls(type="camera")
    return cams
 
##getCams(fileToOpen)

How do I do i get return list of items from reaadMayaFle.py to fill up the QComboBox ?

basically if you have any other idea to get list of cameras from scene other than parse ma file is good

Ok, now we can discuss. Thats the purpiose of boards. So lets get this straight your trying to build a gui for batch rendering, right? Is there any particular reason why you can not launch it via maya? I mean its prefectly possible to supress the entire maya GUI and replace with your own. In this case it MIght be worth it, as you would gain a lot of extra features with the same penalty as your getting now. Though possibly not.

Tell me aboyt the environment where you wish this to work.

Ok a sample:

#!/usr/bin/python
# -*- coding: utf-8 -*-
 
import sys
import readMayaFile
from PyQt4 import QtGui, QtCore
 
class Example(QtGui.QWidget):
 
    def __init__(self):
        super(Example, self).__init__()
 
        self.initUI()
 
    def initUI(self):      
 
        self.lbl = QtGui.QLabel('', self)
 
        combo = QtGui.QComboBox(self)
        combo.addItems(readMayaFile.getCams('path'))
        self.show()
 
 
def main():
 
    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())
 
 
if __name__ == '__main__':
    main()

PS: maya.standalone.initialize(name='python') is a Really slow call, because it essentially starts a maya, be sure to ensure you ONLY ever call it once.
