In this particular case, we do this by implementing a custom
pqPropertyWidget subclass that handles this. The class of interest
is pqCubeAxesPropertyWidget.

In this particular case, this too is managed by a custom widget
(pqPointSpriteControls). However, one can use PropertyWidgetDecorators
(described here
http://www.paraview.org/Wiki/ParaView/Properties_Panel#pqPropertyWidgetDecorator_.28base-class:_QObject.29)
for similar effect. Just search for Decorator in the filters.xml and you'll
see several examples of using decorator to enable/disable widgets based on
values of other properties. You can also define new decorators through
plugins.

Custom widget here too. You can write a pqPropertyWidget subclass that
handles such customizations. A pqPropertyWidget can correspond to a single
property or a group of properties.

You know it...custom widget for two properties. But those in a property
group and create a new widget for that group.
