till now I've successfully integrated wxWindows and VTK in my own
application by using the wxVTKRenderWindowInteractor class.
I have developed a driver for a new interaction device and a
wxWidgetsCustomEvent class that handles the events it generates, now I want
to invoke some vtkUserEvents by using the Callback functions associated to
I' ve added the observers and the callback functions of my vtkUserEvents
in vtkInteractorStyle and I've developed a subclass of vtkinteractorStyle
with the necessary functionalities.
If i invoke my vtkEvents from a function associated to a standard wxEvent it
works fine. The problem is that if I invoke the vtkEvents from a function
associated to a custom wxEvent, VTK seems to lose the focus and if I invoke
a grabfocus or a dolly, the application crashes by an error in
After my vtkEvent is invoked the first time, is invoked a
vtkCommand::LeaveEvent like the mouse pointer leaves the vtkwindow, how
could i avoid this invocation and such situation?
Can i invoke vtkEvent from a wxCustomEvent without provoking render or
I hope someone can explain me the steps needed in order to create
vtkCustomEvents that can answer to my wxCustomEvents like to standard
Thanks to everybody.
