[vtk-developers] initial properties in widget representations

[Amy Squillacote]

Hi all,

In an application I'm working on, I'm using some of the widgets that use 
the widget/representation framework. I want to change some of the values 
in the non-selected vtkProperty's (e.g., change the color in the 
OutlineProperty of vtkImplicitPlaneRepresentation) and have these values 
take effect when the widget is enabled. At the moment, this doesn't work 
because the OutlineProperty (or SelectedOutlineProperty) is only set on 
the OutlineActor when the state of the widget changes. (You can call 
SetRepresentationState to some non-0 value and then back to 0 to force 
the behavior I'm looking for, but this seems very hackish.) Does anyone 
know why the non-selected properties are not set on their associated 
actors in the constructor?

In the constructor, after the call to CreateDefaultProperties, I would 
like to add code to set the non-selected properties (NormalProperty, 
PlaneProperty, and OutlineProperty) on the corresponding actors. Does 
anyone see a problem with this?

- Amy
