Dear VTK users,<br>
<br>
I am using a VTKGraphLayoutView to display a graph. The user may select individual vertices and other linked views shall be updated accordingly. Now, I would like to offer different kinds of selections, e.g., "Include this vertex", "Do not include this vertex",..., and colorize the vertex according to the selection type. I set up a point lookup table and change its values accordingly. Although this works in principle, the color of a currently selected vertex gets overwritten (on the screen) by the picking/highlighting color. Is there a way to avoid this?<br>
</blockquote><div><br></div><div>Unfortunately, no. You can change the selection color using the view theme, but cannot disable it. Internally vtkGraphLayoutView uses vtkApplyColors, which does not appear to have that capability:</div>
