<div dir="ltr">Hi Erich Purpur,<div><br></div><div>I am a Python coding beginner and made some changes according to your reply. I have a XYZ connection for OpenStreetMap. But after hitting the button wipeAllConnectionsXyz in a QGIS Plugin, I did not get any error message, but the OSM connection was not removed.

This is not an object which holds multiple items, which is the purpose of a loop. However, in your getGroupXYZ() function, you return an object called groupsXYZ. You should loop of the groupsXYZ object, not the function.</div><div><br></div><div>-Erich</div><div><br></div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 23, 2020 at 11:38 AM 1520 gis <<a href="mailto:juliermeopensourcedeveloper@gmail.com" target="_blank">juliermeopensourcedeveloper@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear all,<div><br></div><div>I am writing a PyQT5 QGIS Plugin to wipe out all xyz connections available in QGS projects.</div><div><br></div><div>I wrote the code below, but I am not achieving my goal and I did not understand the structure of xyz connections.</div><div><br></div><div><div style="color:rgb(212,212,212);background-color:rgb(30,30,30);font-family:"Droid Sans Mono",monospace,monospace,"Droid Sans Fallback";font-size:24px;line-height:32px;white-space:pre-wrap"><div><span style="color:rgb(86,156,214)">def</span> <span style="color:rgb(220,220,170)">removeAllConnectionsXYZ</span>(<span style="color:rgb(156,220,254)">self</span>):</div><div> s = QSettings()</div><div> xyz = <span style="color:rgb(206,145,120)">'qgis/connections-xyz'</span></div><div> groupsXYZ = s.childGroups()</div><br><div> <span style="color:rgb(197,134,192)">for</span> group <span style="color:rgb(86,156,214)">in</span> groupsXYZ:</div><div> s.beginGroup(xyz)</div><div> s.remove(<span style="color:rgb(206,145,120)">""</span>)</div><div> s.endGroup()</div><div><div style="line-height:32px"><div><span style="color:rgb(86,156,214)">self</span>.dlg.wipeAllConnectionsXyz.clicked.connect(</div><div> <span style="color:rgb(86,156,214)">self</span>.removeAllConnectionsXYZ)</div><div><br></div><div><br></div><div><br></div><div><br></div><div># Any comment will be very appreciated.</div><div><br></div><div>#Thank you for your time in advance</div><div><br></div><div>#Julierme</div></div></div></div></div></div>
