I want to display the `DoubleVectorProperty` with an exclusive group of `QRadioButton`, each of which reflects a double value, by paraview’s custom propertiesPanel mechanism.  
Referring to example `pqMyPropertyWidget` from paraview source, I built my custom filter plugin and loaded the dll successfully(i.e. I didn’t encounter any errors nor warnings). However, after I applied my custom filter, the widget(which is a QGroupBox with several radiobuttons) I’m expectant of didn’t show up in the `propertiesPanel`, nothing there, without any errors being raised though. So I’m not sure which part of my plugin went wrong.  
Here is my source file:  
[propertySrc.rar](https://discourse.paraview.org/uploads/short-url/10yZswZNoT3g3T9CDMkQYz6CsOe.rar) (3.3 KB)  
Anyone please help me on this?

Thanks.

Yohsino.

I do not see anything wrong in your code. Put some trace in your widget constructor to see if it is actually created.
