[vtkusers] RPD - GUIVTK demo (please try)

[John Anast-JM]

John,

Spent a few hours playing with the RPD. I think its great. What can we expect in
the future of this? Might this become public domain or will it be a commercial
product?? How does this fit in with the threads on building a GUI for vtk.
Thanks for sharing this...

Apologies for not setting this up yesterday, I forgot that I had the day
off (collecting a piano).

The following URL contains a demo of RPD = rapid pipeline design, a GUI for
vtk as well as a development environment for the work I'm doing. It should
run for 30 days before ceasing to work.

The version I'm posting is fairly stable
(I found a bug in Celllocator last night when creating the raytrace demo,
see if you can find it too!) -
but some features are in the middle of being "adjusted". Here are some tips :

If you load an app and it has many windows which go 'off' the screen, try
resizing something, this makes the scrollbars appear and you can find
things better. This is a bit flakey and sometimes the windows will shift
about and you'll get strange effects. (Fix awaiting)

Some widgets and filters are just shells and do nothing, so if you play
with one for a moment and can't make it do anything, play with something
else :)

Filters (or any vtkObjectLike derivative) and their GUI wrappers are
compiled into DLL's, if an app is saved and a user loads it without the
necessary DLL loaded, an error is reported and the demo will not function
correctly. It should load OK, but won't obviously do what's supposed to
happen.

The (special widget) GUI boxes should not be deleted when parameters are
inside them. If you do, when the windows are destroyed certain components
will be deleted twice. This is a new approach to an old problem I've been
looking at and it's not finished yet. sorry.

I rewrote a large chunk of window/actor binding code and occasionally,
actors don't appear in windows. Delete the window, delete the actor, the
recreate the window and actor in that order, then drag drop the actor on
thw window and it should reset itself. I'll fix this too.

The 3D window has some menus and controls, the controls are experimental
and not all connected to the internal code.

writers.dll has been omitted, so you cannot save any interesting *.vtk
files you generate. sorry. (Also NB. All DLL's are full debug versions and
a bit large - especially vtkdll.dll)

Please Enjoy and I welcome feedback. I've already received a number of
queries regarding RPD and I'll try to answer them over the next few days.
Thanks.

John B
