I am trying to make a custom UI panel based on the current Threshold panel. So far I created the UI file and copied and modified the pq files for the UI.<br><br>The problem is I get this error when loading the filter:<br><br>
QObject::connect: Cannot connect (null)::valueChanged(double) to SumBillboardPanel::upperChanged(double)<br>QObject::connect: Cannot connect (null)::valueChanged(double) to SumBillboardPanel::lowerChanged(double)<br><br><br>
Which references this section of my file:<br><br>pqSumBillboardPanel::pqSumBillboardPanel(pqProxy* pxy, QWidget* p) :<br>&nbsp; pqLoadedFormObjectPanel(&quot;SumBillboard.ui&quot;, pxy, p)<br>{&nbsp; <br>&nbsp; this-&gt;Lower = this-&gt;findChild&lt;pqDoubleRangeWidget*&gt;(&quot;ThresholdBetween_0&quot;);
<br>&nbsp; this-&gt;Upper = this-&gt;findChild&lt;pqDoubleRangeWidget*&gt;(&quot;ThresholdBetween_1&quot;);<br><br>&nbsp;&nbsp; QObject::connect(this-&gt;Lower, SIGNAL(valueChanged(double)),<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; this, SLOT(lowerChanged(double)));
<br>&nbsp;&nbsp; QObject::connect(this-&gt;Upper, SIGNAL(valueChanged(double)),<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; this, SLOT(upperChanged(double)));<br><br>&nbsp; this-&gt;linkServerManagerProperties();<br>}<br><br>Now I think the problem is that the UI file isn&#39;t being loaded properly, but I have no clue why as everything is in the same directory and named correctly. Does anybody have any tips on getting this to work?
