[vtkusers] Pick Method...

[Patric.Weis at mycrona.de]

Hi Monsieur Duck,

Derive your own interactor style class from vtkInteractorStyle (or one of
its derived subclasses. e.g. vtkInteractorStyleTrackball).
Then override the appropriate default mouse operation (e.g
vtkInteractorStyle::OnLeftButtonUp()) to implement your picking.
In the overridden function you can call the keycode operation for picking.
Be aware that the mouse operations normally are used for rotation or
zooming. So maybe you also have to call the default mouse operation, e.g.

if (ctrl == 0) && (shift == 0)
{
    OnChar(ctrl, shift, 'p', 1);
}
else if (...)
{
   ...
}
vtkInteractorStyle::OnLeftButtonUp(ctrl, shift, X, Y);

Hope this helps!

   Hi Vtk List

   How can I change the default method to pick an actor (typing 'p')?... I
   want to do that with a click mouse...

   Thanks
