Difference PyQt4/PySide in "Tutorial : PyQt4 UI Development for maya by Justin Israel"

[Jean Noval]

Hello Justin Israel,

I'm watching your videos series "Tutorial : PyQt4 UI Development for maya" but I'm working with PySide rather than PyQt.
So I made so changes in your files as shown below :

#Difference between PyQt4 and PySide in maya

#Import differences
from PyQt4 import QtCore, QtGui
from PySide import QtCore, QtGui

import sip
import shiboken

#Difference between sip and shiboken
mainWin = sip.wrapinstance(long(ptr), QtCore.QObject)
mainWin = shiboken.wrapInstance(long(ptr), QtGui.QWidget)

name = mui.MQtUtil.fullName(long(sip.unwrapinstance(win)))
name = mui.MQtUtil.fullName(long(shiboken.getCppPointer(win)[0]))

In Chapter 06 you are showing channelBox.py
And when I show it with the showChannelBox() class method it works fine I have a empty UI with the same height and size,
But then, when I select an object I only see the object's name (top left)  and Visibility under it. I don't see the others attribute.

Do you why the UI is not diplaying correctly ?

I made some screenshots, UI with selection, then UI without selection :

Hi

That's a good question. I can try and look into this tonight, unless someone else beats me to it :-)

Thanks Justin, I am looking forward to your response !
By the way I'm using Maya 2014

Hey there,

I found the reason it was showing up strangely under PySide. It is because the code was using a now deprecated method, on QTableWidgetItem. In the "showAttributes()" method, you need to change this line:

item.setBackgroundColor(QtGui.QColor(40,40,40))

​

to

item.setBackground(QtGui.QBrush(QtGui.QColor(40,40,40)))

​

It was still valid in PyQt4, but in PySide has been changed. For me, I got a warning printing out in the Script Editor. Basically the loop would crash while setting up the attributes, so you ended up with a partially constructed channel box.

Hi

How do you make a code block Justin?

I would like to throw in what I found updating my script to PySide in the flowlayout. The example that comes with PySide itself was using some deprecated method too. The setMargin

if parent is not None:
    self.setMargin(margin)

The new one is setContentsMargins which takes 4 arguments for margin of each side. Just my quick silly fix.

if parent is not None:
    self.setContentsMargins(margin, margin, margin, margin)

the margin() method is deprecated too, so need to change this.

2 * self.margin()

to this

2 * self.getContentsMargins()[0]

You mean the email-formatted code blocks? A few of us are using that Markdown-Here browser plugin:

You just mark up a block with 

```[optional lang]  

code code code

```

And hit the button :-)

Thanks for the answer !

Is there a list with the differences between PyQt4 PySide somewhere on the internet ?

I'm still learning PySide so it could be useful for me.

[Justin Israel]

http://pyqt.sourceforge.net/Docs/PyQt4/new_style_signals_slots.html

https://wiki.qt.io/Differences_Between_PySide_and_PyQt

This specific case was more of it being a now deprecated function used back when it wasn't deprecated.
