[Paraview-developers] Access to the color legend and its modification

Tue Dec 9 03:09:38 EST 2014

In order to avoid misconceptions about first part of topic, I will explain
in more detail my actions.
In fact, I need create a button in Properties panel, preferably in the Display
panel.
Is it possible to display the button within the selected filter?
If no, it is not so important, because I can disable the button depending
on whether the field array is selected, can't I?
As I could not create a subclass of pqColorEditorPropertyWidge class for
the reasons described in my previous reply.
I create a new representation because I do not see another solution to
define my property widget in the Display panel.
After that, I extend the standard UnstructuredGridRepresentation by adding
my representation. (But I didn't want to create a new representation)

I appreciate any your help.
