Problem summary
As part of the Katana 3.1 release, Katana has updated its version of Qt from 4.8.5 to 5.6.1, as specified in the VFX Reference Platform CY2017.
This has caused some unintended behaviours to Nodes using the QT4FormWidgets library.
As an example, within the PonyStack Node available by the Katana example recourses folder, when displayed it throws the following traceback:
Error in event handler __idle_callback() for event type "event_idle": AttributeError: 'GroupFormItem' object has no attribute 'updatedSize' Utils.EventModule 2019-01-22T09:51:01Traceback (most recent call last): File "bin\software_python\Utils\v5\EventModuleUI.py", line 129, in __invokeHandlerDict File "plugins\Resources\Examples\SuperTools\PonyStack\v1\Editor.py", line 137, in __idle_callback File "plugins\Resources\Examples\SuperTools\PonyStack\v1\Editor.py", line 186, in __updateTreeContents File "plugins\Resources\Examples\SuperTools\PonyStack\v1\Editor.py", line 215, in __treeWidgetSelectionChanged File "bin\python\UI4\software_python\QT4FormWidgets\v0\FormItemTree.py", line 159, in buildLayoutItem File "bin\python\UI4\software_python\QT4FormWidgets\v0\FormItemLayout.py", line 423, in __init__ File "bin\python\UI4\software_python\QT4FormWidgets\v0\FormItemLayout.py", line 63, in __init__ File "bin\python\UI4\software_python\QT4FormWidgets\v0\FormItemLayout.py", line 426, in _setup File "bin\python\UI4\software_python\QT4FormWidgets\v0\FormItemLayout.py", line 104, in _setupAttributeError: 'GroupFormItem' object has no attribute 'updatedSize'
