How can I parent a new button to the channel box in Maya using PySide?

I have a very basic understanding of PySide. I'm hoping to parent a button to the existing Channel Box. However I'm not sure where to start outside of getting the main Maya window. (But I'm not even sure this is correct):

from PySide import QtGui, QtCore
from shiboken import wrapInstance
from maya.OpenMayaUI import MQtUtil

channelBox = wrapInstance(long(MQtUtil.findControl('mainChannelBox')), QtGui.QWidget)

Messing up with Maya's UI can be a difficult task, there are two ways to do so. First is to use maya.cmds to add widgets to Maya's UI. The second one is to wrap, just like you did, a Maya widget in a Qt class.

The is a similar question here: How do I parent new, user-created buttons inside the Graph Editor window? I answered with maya.cmds code only and there is an other answer that might interest you as well using PySide.

Here is a solution:

nbIteration = 0
def getChildren(uiItem, nbIteration):
    for childItem in cmds.layout(uiItem, query=True, childArray=True):
        try:
            print "|___"*nbIteration + childItem
            getChildren(uiItem + "|" + childItem, nbIteration+1)
        except:
            pass
getChildren("MayaWindow|MainChannelsLayersLayout", nbIteration)

If you run this code, this will give you the name on the widgets contained in the Channel Box / Layer Editor 

ChannelButtonForm <-- This is the form containing the 3 buttons on the top-right 
|___cbManipsButton
|___cbSpeedButton
|___cbHyperbolicButton
ChannelsLayersPaneLayout <-- This is the layout containing the channel box and the layer editor. A paneLayout has a splitter to resize his childrens.
|___ChannelBoxForm 
|___|___menuBarLayout1 
|___|___|___frameLayout1
|___|___|___|___mainChannelBox
|___LayerEditorForm
|___|___DisplayLayerUITabLayout
|___|___|___DisplayLayerTab
|___|___|___|___formLayout3

Depending on where you want your button to be snapped, you'll have to choose a layout as parent for your button.

In this case, I'm placing a button on the top-left part of the Channel Box/Layer Editor, on the same level as the 3 checkboxButtons.

import maya.cmds as cmds

cmds.button("DrHaze_NewButton", l="HELLO", p="MayaWindow|MainChannelsLayersLayout|ChannelButtonForm")

As you didn't tell us where you want your button to be placed, you'll have to edit your question if you want something more appropriate.
