<p><font size="-1"><font face="Century Gothic">Hello,<br>
i'm developing a QGIS plugin algorithm that composes a print
layout.<br>
The attached code works but the map window appears in the
composer with the word "Rendering map".<br>
and I get these messages:<br>
<br>
WARNING QObject::connect: Cannot queue arguments of type
'QItemSelection'<br>
(Make sure 'QItemSelection' is registered using
qRegisterMetaType().)<br>

<br>
Only after saving and reopening QGIS do I get the correct
result in the composer.<br>
<br>
What is missing to make it work properly?<br>
<br>
Can someone help me?</font></font><br>
