This is a cross application, cross platform and open source Python editor, which can be run as a standalone application or embedded in another application. The main purpose for integration - the ability to script in Python.

• Preserve and load of tabs and code in them
• Interactive execute of the selected code by pressing Ctrl + Enter
• Adjust the color theme of the code editor
• Code completion (module jedi)
• Context completion for different functions like existing nodes and path in scene

• Houdini 13 and 14 (using hqt.py module)
• Nuke 8,9
• Maya 2014-2016
• 3DsMax 2014-2016

If necessary, you can extend this to make your own integration module. The main pre condition - Should be used Python2.7.

• Code completion for all modules and return types (remastered hou library)
• Context completion for functions CreateNode, CreateInputNode and CreateOutputNode with existing houdini node types
• Context completion string for absolute houdini internal path and node parameters. To use this complete start string with "/ or '/
• Drag&Drop Houdini nodes and parameters fills in their path. Use Alt modifier to wrap node or parameter as code like in Houdini Python Shell.
• Reading and writing to PythonSOP code and asset sections

• Code completion for all modules and return types (remastered nuke library)
• Context completion for createNode with existing Nuke node types
• Context completion for function toNode with existing nodes in current script
• Converting selected nodes to code with function nuke.toNode
• Searching and converting nodes to code from clipboard
• Reading and writing from PythonKnobs code

• Save code to shelf and accept dropped shelf button code, like default Maya script editor
• Drag&Drop Maya nodes fills in their names. Use Alt modifier to wrap node as code. Import PyMEL before doing this!
• Context completion for function PyNode with existing nodes in current scene
• Context completion for function pm.createNode and cmds.createNode with existing Maya node types

• Works for now...

• install Python 2.7
• install PySide
• use run.cmd (Windows) or run.sh (Linux) to start

• download and install hqt.py
• install PySide to default Python interpreter
• create new tool on shelf

import sys
paths = ['path/to/folder/with/MultiScriptEditor_module','path/to/default/python27/lib/with/PySide']
# example ['c:/houdini/python/lib', 'c:/python27/Lib/site-packages']
for path in paths:
    if not path in sys.path:
        sys.path.append(path)
import pw_multiScriptEditor
pw_multiScriptEditor.showHoudini(ontop=1)

• download and install hqt.py
• create new tool on shelf

import sys
path = 'path/to/folder/with/MultiScriptEditor_module'
# example c:/houdini/python/lib
if not path in sys.path:
    sys.path.append(path)
import pw_multiScriptEditor
pw_multiScriptEditor.showHoudini(name='Multi Script Editor',replacePyPanel=1, hideTitleMenu=0)

Also you can use .pypanel file without hqt module

/managers/houdini/pw_MultiScriptEditor.pypanel

• Create shelf button with code

import sys
path = 'path/to/folder/with/MultiScriptEditor_module'
# example c:/maya/python/lib
if not path in sys.path:
    sys.path.append(path)
import pw_multiScriptEditor
pw_multiScriptEditor.showMaya(dock=True)

• Add next code to menu.py

import nuke
menubar = nuke.menu("Nuke")
toolMenu = menubar.addMenu('&Tools')
path = 'path/to/folder/with/MultiScriptEditor_module'
# example c:/nuke/python/lib
if not path in sys.path:
    sys.path.append(path)

import pw_multiScriptEditor
# add to menu
toolMenu.addCommand("Multi Script Editor", "pw_multiScriptEditor.showNuke()")
# create new pane
pw_multiScriptEditor.showNuke(panel=True)

• Create a menu, toolbar, etc with the following maxscript:

python.executefile("path\\to\\pw_multiScriptEditor\\run_3dsmax.py")
