|Summary||0032657: Visualization - Select Wireframe Shape when Display in Wireframe Mode|
|Description||When switch Shading (S + Ctrl) to Wireframe (W + Ctrl) display mode, the sensitive entity is remain the Triangulation not wire or curve, thus the shape behind cannot be selected directly.|
|Tags||No tags attached.|
|Test case number|
It doesn't matter which display mode is used for AIS_Shape - Wireframe or Shaded.
In both cases selection is computed in the same way based on triangulation - this is by design (e.g. not a bug).
If it doesn't work for you - consider sub-classing AIS_Shape (by overriding ::ComputeSelection()) or contributing to OCCT, and implementing it in a different way - like exploding shape into wires and building selection from it (this wouldn't handle Isolines though, since they are not part of shape definition).
Yes, this is not a bug. The selection mode has no relation with display mode, it is set by AIS_InteractiveContext::Activate().
When display shapes in Wireframe mode, selection will be more intuitive and efficiency that the Wireframe shape can be selected, because less overlap.
I will try it and contribute when it works.
