[vtkusers] giving renderwindow a name

[michiel mentink]

thanks guys, I've the title working now.

For a touch of perfection; is there a way to automatically set the window
coordinates so that the windows are aligned wherever you want them?
(i.e. next to each other?)


And one last question: after the first render window has been created, the
program waits for me to press 'q' to continue the program. Is
there a way for the program to continue without pressing 'q'?

I tried: renwindow->Finalize(); // doesn't do anything

windowinteractor->TerminateApp(); // this closes the application altogether
when 'q' is pressed

windowinteractor->UnRegister(); // error: no matching function call
                                               // note: candidates are:
virtual void vtkRenderWindowInteractor::UnRegister(vtkObjectBase*)

windowinteractor->CreateOneShotTimer(1); // doesn't release focus

I'd just like all windows to pop up as soon as possible and be able to
manipulate them with my mouse whenever I'd like to.
At this point I can manipulate all renderwindows fine, I'd just like the
windows to appear without having to press 'q'.

cheers, Michael
