MAXscript Listener can not run Pyside - python-2.7

Question

Please help me !
I'm creating GUI by Python can run on the 3Ds Max, i heard someone said i have to use Pyside to make it. And everthing be fine until now.
This is my code :
import sys
from PySide import QtGui
from PySide.QtGui import *
from PySide.QtCore import *
class Window(QDialog):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
self.setMinimumHeight(660)
self.setMinimumWidth(700)
self.setMaximumHeight(660)
self.setMaximumWidth(700)
grid = QtGui.QGridLayout()
grid.addWidget(self.First(), 0,0,2,0)
self.setLayout(grid)
self.setWindowTitle("Library")
self.resize(700, 660)
def First(self):
groupBox = QtGui.QFrame()
groupBox.setMaximumWidth(230)
groupBox.setMaximumHeight(700)
lbRenderer = QtGui.QLabel("Renderer :",self)
lbFolders = QtGui.QLabel("Folders :",self)
cbRenderer = QtGui.QComboBox(self)
cbRenderer.addItem("Vray")
cbRenderer.addItem("Octane")
lvFolders = QtGui.QListView(self)
lvFolders.setMaximumWidth(220)
lvFolders.setMaximumHeight(500)
btnAddNewObject = QtGui.QPushButton('Add New Objects',self)
btnNewSet = QtGui.QPushButton('New Set',self)
vbox = QtGui.QGridLayout()
vbox.addWidget(lbRenderer,0,0)
vbox.addWidget(cbRenderer,0,1,1,3)
vbox.addWidget(lbFolders,2,0,1,4)
vbox.addWidget(lvFolders,3,0,1,4)
vbox.setColumnStretch(1, 1)
vbox.addWidget(btnAddNewObject,4,0,1,2)
vbox.addWidget(btnNewSet,4,3)
groupBox.setLayout(vbox)
return groupBox
app = QApplication.instance()
if app is None:
app = QApplication(sys.argv)
clock = Window()
clock.show()
app.exec_()
I try another code same like my code , it run fine by "MAXScript Listener". But I dont know why when i try to run this, it dont appear anything(my GUI, or Alert is my code is not good).

Answer 1

First of all - you are initializing your script wrong, you call the 'initialize' function which returns #Success (meaning python initialized properly),
however you then just send in a string (which is the path to the file) and this does nothing.
What you have to use is:
python.ExecuteFile "C:\\Program Files\\Autodesk\\3ds Max 2015\\scripts\\Python\\yourPythonScript.py"
in maxscript listener\editor.
Autodesk documentation says:
Autodesk 3ds Max ships with a pre-built version of PySide 1.2
compatible with Python 2.7.3. This version includes the following
sub-set of modules:
QtCore
QtGui
QtNetwork
QtOpenGL
QtSql
QtSvg
QtTest
QtWebKit
QtXml
They have provided a simple sample script that you can run, save this in a python file, then execute it properly with the command mentioned in the beginning.
The code is here:
from PySide import QtGui
import MaxPlus
class _GCProtector(object):
widgets = []
def make_cylinder():
obj = MaxPlus.Factory.CreateGeomObject(MaxPlus.ClassIds.Cylinder)
obj.ParameterBlock.Radius.Value = 10.0
obj.ParameterBlock.Height.Value = 30.0
node = MaxPlus.Factory.CreateNode(obj)
time = MaxPlus.Core.GetCurrentTime()
MaxPlus.ViewportManager.RedrawViews(time)
return
app = QtGui.QApplication.instance()
if not app:
app = QtGui.QApplication([])
def main():
MaxPlus.FileManager.Reset(True)
w = QtGui.QWidget()
w.resize(250, 100)
w.setWindowTitle('Window')
_GCProtector.widgets.append(w)
w.show()
main_layout = QtGui.QVBoxLayout()
label = QtGui.QLabel("Click button to create a cylinder in the scene")
main_layout.addWidget(label)
cylinder_btn = QtGui.QPushButton("Cylinder")
main_layout.addWidget(cylinder_btn)
w.setLayout(main_layout)
cylinder_btn.clicked.connect(make_cylinder)
if __name__ == '__main__':
main()
They also mention this which is important:
Normally one creates a PySide application object in a script using
QtGui.QApplication(). However, in 3ds Max, there is already a PySide
application running, so you get a handle for that object like this:
QtGui.QApplication.instance()
Use that as a start script, and port your GUI items into that and it should get you up and running.

I tried to fix your code but anything happen, i dont know why.
First thing , i opened your code and run it in Pycharm but it can not run. But it totally run in Maxscript Listener, could you explain to me ?
Second i tried to fix your code. It's all the same, i can run it on Maxscript, but the content and function inside is disappear.
This is my code
from PySide import QtGui
import MaxPlus
class _GCProtector(object):
widgets = []
app = QtGui.QApplication.instance()
if not app:
app = QtGui.QApplication([])
def main():
MaxPlus.FileManager.Reset(True)
w = QtGui.QWidget()
w.setWindowTitle('Window')
_GCProtector.widgets.append(w)
w.show()
main_layout = QtGui.QGridLayout()
main_layout.addWidget(First(),0,0)
main_layout.addWidget(Second(),0,1)
w.setLayout(main_layout)
def First():
groupBox = QtGui.QFrame()
lbRenderer = QtGui.QLabel("Renderer :",self)
vbox = QtGui.QGridLayout()
vbox.addWidget(lbRenderer,0,0)
groupBox.setLayout(vbox)
return groupBox
def Second():
groupBox = QtGui.QFrame()
lbRenderer = QtGui.QLabel("Renderer :",self)
vbox = QtGui.QGridLayout()
vbox.addWidget(lbRenderer,0,0)
groupBox.setLayout(vbox)
return groupBox
if __name__ == '__main__':
main()
And this is the alert from Maxcript
