[vtkusers] ActiViz | vtkRenderWindowInteractor Start event

[David Cole]

Do you have a "main"?

Are you calling "Application::Run(form);"?

WinForms will run a message loop for you if you call the Application 
Run method. In that sense, it does exactly the same thing conceptually 
as vtkRenderWindowInteractor::Start.

The message loop usually looks something like this, if you look at the 
source code for one:

    while (GetMessage(&msg, ...))
    {
      TranslateMessage(&msg);
      DispatchMessage(&msg);
    }

Hi David, thanks for the response.


I'm using this into a Windows Form Application. What would be my 
message loop? I'm not quite sure what that means, can you explain a bit 
more?


Thanks!

iren.Start(); runs a message loop, and doesn't exit until you as a user 
exit that window (either press the 'q' key, or close the window)

If you don't want that because you're building this into an application 
where you already have your own message loop, then simply don't call 
iren.Start();...

Instead, call "renwin.Render();" to show the window and render its 
contents. If you're running in the context of a WinForms application, 
or something like it, then your message loop should suffice to cause 
events to be processed for the render window.
