vtkmodules.gtk.GtkVTKRenderWindowInteractor#

Description:

Provides a pyGtk vtkRenderWindowInteractor widget. This embeds a vtkRenderWindow inside a GTK widget and uses the vtkGenericRenderWindowInteractor for the event handling. This is based on vtkTkRenderWindow.py.

The class uses the gtkgl.GtkGLArea widget (gtkglarea). This avoids a lot of problems with flicker.

There is a working example at the bottom.

Created by Prabhu Ramachandran, April 2002.

Bugs:

(*) There is a focus related problem. Tkinter has a focus object that handles focus events. I don’t know of an equivalent object under GTK. So, when an ‘enter_notify_event’ is received on the GtkVTKRenderWindow I grab the focus but I don’t know what to do when I get a ‘leave_notify_event’.

(*) Will not work under Win32 because it uses the XID of a window in OnRealize. Suggestions to fix this will be appreciated.
