Hello!

For example I have such a property

```auto
		<IntVectorProperty
			label=
			name=
		</IntVectorProperty>

```

Where can I get the information on which kind of widget will be generated for that?

Like, where are all these xml things defined?

Thanks

In ParaView’s source code, `Qt/Components/pqProxyWidget.cxx` implements [`pqProxyWidget::createWidgetForProperty()`](https://gitlab.kitware.com/paraview/paraview/-/blob/v5.13.2/Qt/Components/pqProxyWidget.cxx#L1331-1357).

Note that the default property widgets are mentioned explicitly, but you can register new widgets at runtime that override these with `pqPropertyWidgetInterface` (the first part of the source code linked above).

Are you asking where to look up examples? See [`Remoting/Application/Resources/*.xml`](https://gitlab.kitware.com/paraview/paraview/-/tree/v5.13.2/Remoting/Application/Resources) for the XML source of ParaView’s native filters/sources.
