PyQt

Identify our aim

So we're going to search the PyQt widget we want thank to the wrapinstance function from sip, aka wrapInstance for shiboken in completion with the wonderful class MQtUtil from OpenMayaUI in order to search inside Maya the widgets we are looking for. First let's find the Maya main window, which will be an easy shot;

Note ; The wrapInstance function needs a unique 'id' corresponding to the QWidget, and the main class of the widget, for our current example we're looking for the main window, so the class will be a QWidget

from PySide import QtCore, QtGui
from shiboken import wrapInstance
from maya.OpenMayaUI import MQtUtil
 
maya_win = wrapInstance(long(MQtUtil.mainWindow()), QWidget)

Fine, now we can loop through children to find the scriptEditor window, several ways of approach can be used, we're just going to find all the children which contains 'script' in their object name, I'm pretty confident this will be the case for our script Editor window =)

for child in maya_win.children():
    if 'script' in child.objectName():
        print 'CHILD => %s' % child.objectName()

One shot ! You should see something like that ;

# CHILD => scriptEditorPanel1Window 

Thank to the wonderful class MQtUtil we can now access to the widget using the function findControl

script_stdout = wrapInstance(long(MQtUtil.findControl('cmdScrollFieldReporter1')), QTextEdit)

Considering the fact that we don't now exactly the index of the widget's name we're going to use a little while loop to find the correct occurence ;

i = 1
while i:
    try:
        se_edit = wrapInstance(long(MQtUtil.findControl('cmdScrollFieldReporter%i' % i)),
                                                        QtGui.QTextEdit)
        break
    except TypeError:
        i += 1

Alright ! Now we have our widget we can work on the coloring
