[Paraview] Problems with external modules

[ALIZIER Julien AUSY]

Hi Berk, hi everyone,

Actually, I am writing vtk filters and a ParaView widgets.

My widget vtkPVMy3DWidget inherits from vtkPV3DWidget.
When it creates all the Tk widgets in the Property panel of the notebook, I
need to call first this->Script("package require vtkmy3dwidgets") before
creating a button with a callback command that is a member of
vtkPVMy3DWidget. Otherwise the callback generates an error when I press the
button.

My class is wrapped in Tcl but this wrapping is not loaded automatically.
 
A better question would be "Is there a way in PV 1.4.2 to load the Tcl
wrapping of an external library when loading the Client/Server wrapped
library?".


Anyway, I am not at all stuck with it, I just wanted to know if there was a
more elegant way to load my TCL wrapped library.

What do you mean by "the same problem"? Are you trying to load your
own VTK filter or a ParaView GUI object?
