<div>Hi,<br>
I'm Simone Melis and I'm sw engineer in an Italian company.<br>
<br>
</div>
<div>I' m using QGis API 3.26 on Ubuntu 20.04, to create an
application GUI using Qt 5.15.2</div>
<div><br>
</div>
<div>I created a vector layer and I can show correctly a
georeferenced pdf image. </div>
<div>Then I added another transparent layer (vector layer) and I
tried to add markers in lat,long points.</div>
<div>Using <span style="color:rgb(128,0,128)">QgsSimpleMarkerSymbolLayer
</span>I can inserted correctly all markers of the same shape and
color. Then I tried to add markers with different shapes and
colors on the same layers; using <span
style="color:rgb(128,0,128)">QgsSimpleMarkerSymbolLayer </span>I
show only one kind of marker. Browsing on internet I found an
example to use <span style="color:rgb(128,0,128)">QgsCategorizedSymbolRenderer</span>.
I tried to implement it in my code but no markers shown. Can you
suggest a correct way to do this?</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
</div>
<div>Simone<br>

</div>
<div>Here code I implemented:</div>
