Hi.
To create a non-blocking Python Qt window, i need:
import pyqt_clarisse
and then:
pyqt_clarisse.exec_(App)

In a pyqt_clarisse.py we call see:
from PyQt4 import QtCore
from PyQt4 import QtGui
So i need to install PyQt4 even if i am going to use PySide only.
( In a studio we use PySide for in-house tools, we have a Python with PySide )
But for now i need to install PyQt just to make custom windows non-blocking.

Later i just replaced some lines in pyqt_clarisse.py to work PyQt or (and) PySide.
And now it works w/o PyQt4 in Python, but just with PySide:

Code: Select all

# from PyQt4 import QtCore
# from PyQt4 import QtGui
# Move import above modules in try block:
try:
    PythonQt = __import__('PySide', globals(), locals(), ['QtCore','QtGui'])
except ImportError:
    PythonQt = __import__('PyQt4', globals(), locals(), ['QtCore','QtGui'])
QtCore = PythonQt.QtCore
QtGui = PythonQt.QtGui


May be you can do something with this issue in feature releases, for example try to import PySide first.

Hi,

Thank you for sharing this with the community !
We've added a feature request waiting for validation (#6471)

Hello,

This feature has been approved and added on 3.5 roadmap.

Going forward with QT5, PyQt5 or PySide2 Python bindings might be in the environment instead.
So this should be taken into account in the future.

We use Qt.py shim layer around all Qt Python bindings, to make it easy to work with in multiple environments (PyQt4, PySide, PyQt5, PySide2)

Hi,
In Clarisse 3.5, PySide2.QtWidgets.QWidget() crashes main QApplication.
So tell me how to use PySide2 in 3.5 and make parent under QMainWindow ??

Thank you

Hi,

This is a normal behavior. In the SDK doc in Clarisse, there is a special section about QT with Clarisse: `file:///YOUR/CLARISSE/iNSTALL/FOLDER/Clarisse/docs/sdk/using_pyqt.html`

Unfortunately, this is only working for PyQt before before 3.6 and for PySide and PyQt since the release of 3.6.
If you want to use PySide2, you have to edit the python file located here: `D:\YOUR/CLARISSE/iNSTALL/FOLDER\Clarisse\python\pyqt_clarisse.py`

You will have to replace the lines that import PyQt4 by PySide2 and maybe some other things (for example, QApplication is not located in QtGui in PySide2 but in QWidgets).

Because it's a feature request, could you please add a new entry in the feature request tracker? https://www.isotropix.com/user/feature

The tricks should allow you to use PySide2 while we discuss about the feature.

Best regards,

I wonder if it's possible in a future Clarisse version that the app itself is running in a Qt event loop directly?
Then parenting custom Qt windows into Clarisse app would be trivial.

I understand porting the Clarisse UI to Qt might be a big undertaking, but very beneficial to provide a full development environment appropriate for vfx industry.

Hello,

This is a good idea but as you know, it will be a long term developing.

You should add a feature request to port the Clarisse UI to QT: https://www.isotropix.com/user/feature

Hey Benoit

Thanks, yeah I logged that as
#8807 - Port the Clarisse UI to QT
