[vtkusers] How to have multipe renderwindows using wxPython (and other wx questions).

[Maurice van de Rijzen]

Dear all,

Recently I changed fvrom using tkInter to wxPython because. as I 
understood from different sources, wxPython is considered to be more
'professional' and it has more widgets. I understood that wx support is 
now in the recent versions of VTK. I can however not finf it the help files.
But besides this my problem is as follows.
Using tkinter I defined a renderWindow that had multiple renderers 
assigned to different parts of the renderwindow using the viewport 
commands. When I migrated to wx I had some problems using the 
windowInteractor using the multiple renderers.
Then I had the idea to  use the size properties of wx frame to create a 
frame with two renderwindows. I did this with the following code (I 
removed the viepwport settings):


frame = wxFrame(None, -1, "wxRenderWindow", size=wxSize(800,800))
widget = wxVTKRenderWindow(frame, -1, position=(1,1),size = 
(400,800),style=wxSIMPLE_BORDER)
widget2 = wxVTKRenderWindow(frame, -1, position=(401,1), size = 
(400,800),style=wxSIMPLE_BORDER)
widget.GetRenderWindow().AddRenderer(ren1)
widget2.GetRenderWindow().AddRenderer(ren2)

The problem now is that the in the left part of the window the correct 
renderer is displayed but not centered, it looks like the size command 
has no effect. Whereas the second widget is displayed correctly.
Is this a problem of VTK or wx?
How can I chech which version of VTK I'm using.
When I instaal the latest version of VTK(Nightly) does it standard 
include wx or do I have to do something extra.
In the current example I include the definition of 'class 
wxVTKRenderWindow' in my source beacuse otherwise I get an messgae it 
doesn't know the wxVTKRenderWindow class. But I do use
from wxPython.wx import *
These are a lot of questions I hope someone is able to help me with some 
of these questions.

Greetings,
Maurice
