Re: [Visualpython-users] Placing Graphics Output on a Printer

[Wayne W. <sie...@sb...>]

I thought I had fixed the link in my e-mail. That's incorrect. Here's
the right one.
<file:///C:/Python25/Lib/site-packages/visual/docs/visual/display.html>.
The three pulldown menus show:
3D objects, Working with objects and Windows/Events/Files. If I select
in the last one, Windows, nothing changes. It continues to show a
description for "Controlling One or More Visual Display Windows". If I
got Mouse Drag, that shows in the description, but the third menu
continues to show "Controlling One or More Visual Display Windows". I
got it. They all work that way. The three menus always show the first
item. I think I'm used to seeing pull downs that actually advance to the
item selected. There is no problem.
