pyside2-uic (5.14) problem with custom classes

[dhabbyc]

Hello Everyone,

Yesterday I updated pyside2 from 5.11 to 5.14 using pip.

When I tried to generate *.py files from the *.ui files I stumbled into a problem. It seems that the latest version is not handling properly the custom classes.

For instance if I have a simple ui file (the file that contains the custom class is named 'power_table.py'):

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>TableViewer</class>
 <widget class="QDialog" name="TableViewer">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>964</width>
    <height>300</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>Table Viewer</string>
  </property>
  <layout class="QGridLayout" name="gridLayout">
   <item row="0" column="1">
    <widget class="QDialogButtonBox" name="buttonBox">
     <property name="orientation">
      <enum>Qt::Vertical</enum>
     </property>
     <property name="standardButtons">
      <set>QDialogButtonBox::Cancel|QDialogButtonBox::Ok</set>
     </property>
    </widget>
   </item>
   <item row="0" column="0">
    <widget class="PowerTableView" name="view_widget" native="true"/>
   </item>
  </layout>
 </widget>
 <customwidgets>
  <customwidget>
   <class>PowerTableView</class>
   <extends>QWidget</extends>
   <header>power_table</header>
  </customwidget>
 </customwidgets>
 <resources/>
 <connections>
  <connection>
   <sender>buttonBox</sender>
   <signal>accepted()</signal>
   <receiver>TableViewer</receiver>
   <slot>accept()</slot>
   <hints>
    <hint type="sourcelabel">
     <x>248</x>
     <y>254</y>
    </hint>
    <hint type="destinationlabel">
     <x>157</x>
     <y>274</y>
    </hint>
   </hints>
  </connection>
  <connection>
   <sender>buttonBox</sender>
   <signal>rejected()</signal>
   <receiver>TableViewer</receiver>
   <slot>reject()</slot>
   <hints>
    <hint type="sourcelabel">
     <x>316</x>
     <y>260</y>
    </hint>
    <hint type="destinationlabel">
     <x>286</x>
     <y>274</y>
    </hint>
   </hints>
  </connection>
 </connections>
</ui>

and use pyside2-uic (v5.14) for generating the repective .py file I get:

from PySide2.QtCore import (QCoreApplication, QMetaObject, QObject, QPoint,
    QRect, QSize, QUrl, Qt)
from PySide2.QtGui import (QBrush, QColor, QConicalGradient, QFont,
    QFontDatabase, QIcon, QLinearGradient, QPalette, QPainter, QPixmap,
    QRadialGradient)
from PySide2.QtWidgets import *

import PowerTableView

class Ui_TableViewer(object):
    def setupUi(self, TableViewer):
        if TableViewer.objectName():
            TableViewer.setObjectName(u"TableViewer")
        TableViewer.resize(964, 300)
        self.gridLayout = QGridLayout(TableViewer)
        self.gridLayout.setObjectName(u"gridLayout")
        self.buttonBox = QDialogButtonBox(TableViewer)
        self.buttonBox.setObjectName(u"buttonBox")
        self.buttonBox.setOrientation(Qt.Vertical)
        self.buttonBox.setStandardButtons(QDialogButtonBox.Cancel|QDialogButtonBox.Ok)

        self.gridLayout.addWidget(self.buttonBox, 0, 1, 1, 1)

        self.view_widget = PowerTableView(TableViewer)
        self.view_widget.setObjectName(u"view_widget")

        self.gridLayout.addWidget(self.view_widget, 0, 0, 1, 1)


        self.retranslateUi(TableViewer)
        self.buttonBox.accepted.connect(TableViewer.accept)
        self.buttonBox.rejected.connect(TableViewer.reject)

        QMetaObject.connectSlotsByName(TableViewer)
    # setupUi

    def retranslateUi(self, TableViewer):
        TableViewer.setWindowTitle(QCoreApplication.translate("TableViewer", u"Table Viewer", None))
    # retranslateUi

but when I use 5.11 version I get:

from PySide2 import QtCore, QtGui, QtWidgets

class Ui_TableViewer(object):
    def setupUi(self, TableViewer):
        TableViewer.setObjectName("TableViewer")
        TableViewer.resize(964, 300)
        self.gridLayout = QtWidgets.QGridLayout(TableViewer)
        self.gridLayout.setObjectName("gridLayout")
        self.buttonBox = QtWidgets.QDialogButtonBox(TableViewer)
        self.buttonBox.setOrientation(QtCore.Qt.Vertical)
        self.buttonBox.setStandardButtons(QtWidgets.QDialogButtonBox.Cancel|QtWidgets.QDialogButtonBox.Ok)
        self.buttonBox.setObjectName("buttonBox")
        self.gridLayout.addWidget(self.buttonBox, 0, 1, 1, 1)
        self.view_widget = PowerTableView(TableViewer)
        self.view_widget.setObjectName("view_widget")
        self.gridLayout.addWidget(self.view_widget, 0, 0, 1, 1)

        self.retranslateUi(TableViewer)
        QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL("accepted()"), TableViewer.accept)
        QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL("rejected()"), TableViewer.reject)
        QtCore.QMetaObject.connectSlotsByName(TableViewer)

    def retranslateUi(self, TableViewer):
        TableViewer.setWindowTitle(QtWidgets.QApplication.translate("TableViewer", "Table Viewer", None, -1))

from power_table import PowerTableView

Any ideas?

Hi,

Indeed, it looks like something is wrong. Can you check with previous versions of PySide2 to see where exactly it changed ?

Hello SGaist!

I will check with whatever is available on pip from version 5.11.

Thanks!

[dhabbyc]

Ok SGaist,

I can confirm that everything works fine until version 5.13.2, that is, the one previous to 5.14 (on pip at least)
