This is ScrollWindow.h in view mode; [Download] [Up]
// The ScrollWindow class is from David S. Joerg (joerg@alliant.mcs.anl.gov)
// It was posted to the net in 1990 and is in the archives at Purdue and Oregon State.
// It is a bit of overkill for this application, since in the lineMatrix and
// symbolMatrix windows we only need to scroll horizontally, and in the legendForm
// window we only need to scroll vertically. Nevertheless, it works, and it may
// be handy to be able to shrink the windows down to a very small size.
// Here is the README file that was posted with it:
//-------------------------------------------------------------------------------
// Autoresizing is a very nice Appkit feature. However, for some Views
// it just doesn't make sense to autoresize. One day I was looking at
// the IB palette, and I noticed that it was completely resizable, but
// none of the interior elements changed. When the palette window was
// smaller than a certain size, >BANG<, a scroller appeared. I'm always
// low on screen space, so I loved it. ScrollWindow does just about the
// same thing. If you're using IB, ScrollWindow is easy to use: 1) make
// your IB Project recognize the ScrollWindow (subclass Window, Parse).
// 2) change the desired window's class from Window to ScrollWindow. 3)
// tell the ScrollWindow to becomeScrollWindow at some point in the
// initialization sequence (at appDidInit time works for me). Or, if
// you're not using IB, you should just [ScrollWindow new] or
// [ScrollWindow newContent:blah:blahblah...] and once you've filled the
// ScrollWindow with Views, tell it to becomeScrollWindow.
//
// You _can_ add more Views or do things to your ScrollWindow after
// you've told it to becomeScrollWindow, but the important thing to
// remember is that you shouldn't touch [someScrollWindow contentView];
// rather, you should message [[someScrollWindow contentView] docView].
// This is because becomeScrollWindow places the old contentView one
// level lower in the View hierarchy, under a newly-created ScrollView.
//
// Unfortunately, a ScrollWindow doesn't send the
// windowWillResize:toSize: or windowDidResize: messages to its delegate.
// It is possible (and easy) to make ScrollWindow do this, but I think it
// would involve NXReponsibleDelegate() and I just didn't want the mess.
//
// A trivial, yet elegant, piece of code. Enjoy.
