<p>Hi. Kyle, I used the decorador like <font size="2"><span style="font-size:10pt;">@<span name="searchHitInReadingPane" id="0.8533341563734917" class="highlight">pyqt</span>Property(int)</span></font> and worked fine for simple types like int, float, bool.
Thank you very much!</p>

<p>Yes, that is what I have in mind too. It is true that I can set each property individually using int, float, bool etc. as type, but using compound types would turn it more organized.</p>
<p>For example, if I have a property called 'range' in a plot widget, I would compose it with two float fields 'min' and 'max'.</p>
<p><br>
</p>
<p>According to some research and attempts, it is possible to use 'PyQt_PyObject' as a type.</p>
<p><br>
</p>
<p></p>
<div><span style="color: rgb(114, 50, 173);"> @pyqtProperty("PyQt_PyObject")</span><br>
<span style="color: rgb(114, 50, 173);"> def pyobj(self):</span><br>
<span style="color: rgb(114, 50, 173);"> return self._pyobj</span><br>
<br>
<span style="color: rgb(114, 50, 173);"> @pyobj.setter</span><br>
<span style="color: rgb(114, 50, 173);"> def</span><span style="color: rgb(114, 50, 173);">
</span><span style="color: rgb(114, 50, 173);">pyobj(self, value):</span><br>
<span style="color: rgb(114, 50, 173);"> self._pyobj = value</span></div>
<p></p>
<p><br>
</p>
<p>The plugin which contains this code loads into QtDesigner. However, pyobj property does not show on the editor and, no matter what type _pyobj is, I always get this message:</p>
<p><span style="color: rgb(114, 50, 173);">"</span><span style="color: rgb(114, 50, 173);">The property "pyobj" of type (unknown) is not supported yet!</span><span style="color: rgb(114, 50, 173);">"</span></p>

I know we can return anything but in either form of a pyqtProperty <br>
definition you are supposed to specify the type of the property in <br>
addition to returning something of that type. I would think that while <br>
the Python side of things might be ok with that, I would not expect the <br>
C++/Qt side to fare so well. Also, how would Qt Designer know how to <br>
handle the type. Even if we take the simple approach of a compound <br>
property containing other properties, in what structure? A regular <br>
class inheriting from QObject? A dict? An ordered dict? I tried a few <br>
but they didn't work with various errors.<br>
<br>
Does anyone have examples of compound typed pyqtProperty's? If it's <br>
possible I would love to learn how.<br>
<br>
Cheers,<br>
