/// Property widget that can be used to edit a proxy set as the value of a
/// ProxyProperty in a pop-up dialog. e.g. RenderView proxy has a "GridActor3D"
/// ProxyProperty which is set to a "GridActor3D" proxy. Using this widget
/// allows the users to edit the properties on this GridActor3D, when present.
///
/// To use this widget, add 'panel_widget="proxy_editor"' to the property's XML.
///
/// Since it's common to have a property on the proxy being edited in the popup
/// dialog which controls its visibility (or enabled state), we add support for
/// putting that property as a checkbox in this pqProxyEditorPropertyWidget
/// itself. For that, one can use `ProxyEditorPropertyWidget` hints.
///
/// Example XML:
/// @code
///   <ProxyProperty name="AxesGrid" ...  >
///     <ProxyListDomain name="proxy_list">
///       <Proxy group="annotations" name="GridAxes3DActor" />
///     </ProxyListDomain>
///     <Hints>
///       <ProxyEditorPropertyWidget property="Visibility" />
///     </Hints>
///   </ProxyProperty>
