Hi,<br>
<br>
I want to use the QItemEditorFactory to register a CustomEditor class for my own CustomType. The official Qt
<a href="https://doc.qt.io/qtforpython-6/overviews/custom-types.html" id="OWAc2b431f4-370c-b43b-a96a-8f1f001d4c38" class="OWAAutoLink" title="https://doc.qt.io/qtforpython-6/overviews/custom-types.html" data-auth="NotApplicable" data-linkindex="0" data-ogsc="" style="margin: 0px;">
documentation</a> dictates the use of either of these two macros for registering custom types to the Qt Meta type system (and subsequent use in the factory): </div>
<div class="elementToProof" style="text-align: left; text-indent: 0px; margin: 0px; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
Q_DECLARE_METATYPE and qRegisterMetaType. </div>
<div class="elementToProof" style="text-align: left; text-indent: 0px; margin: 0px; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">

Since I don't care about signals/slots mechanism, the first macro is the obvious choice.</div>
<div class="elementToProof" style="text-align: left; text-indent: 0px; margin: 0px; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">

>From the study of the <a href="https://www.riverbankcomputing.com/static/Docs/PyQt5/api/qtcore/qmetatype.html" id="LPlnk761904" title="https://www.riverbankcomputing.com/static/Docs/PyQt5/api/qtcore/qmetatype.html">
PyQt documentation</a>, this macro should be supported and probably it should exist by importing the PyQt5.QtCore.QMetaType module.</div>
<div class="elementToProof" style="text-align: left; text-indent: 0px; margin: 0px; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
<br>
However, that is not the case. My python interpreter (version 3.9.7) gives me an error : NameError: name 'Q_DECLARE_METATYPE' is not defined. <br>
<br>
Here is a snippet from my source code:<br>
<br>
from PyQt5.QtCore import QMetaType</div>
<div class="elementToProof" style="text-align: left; text-indent: 0px; margin: 0px; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
class CustomType:</div>
<div style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
def __init__(self) -> None:</div>
<div style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">

<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
Q_DECLARE_METATYPE(MyClass)<br>

</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">

<div class="elementToProof" style="text-align: left; margin: 0px; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
Naturally, I tried invoking the qRegisterMetaType as well, with similar results. What am I doing wrong? Do these macros exist in PyQt5 (version 5.15.6)<br>
<br>
Thank you in advance,</div>
