The amount of information that I'm trying to display in a window
finally grew to where I needed to put it all in a scrollview. No
problem, I thought. In Interface Builder, I selected all of the text
fields and boxes, then selected Layout->Make subviews of->Scroll View.
This creates a scrollview that is *just* big enough to enclose all of
the objects within. It's a little tight, so I grab the edges of the
scrollview and make it bigger. Then I tried to move the enclosed
objects around. Grabbed a text field, dragged it to the right, it
starts to disappear.
Ok, so putting things into a scrollview actually puts them into an
NSView inside an NSScrollView, and resizing the scrollview doesn't
resize the view inside. But I found that I cannot reliably grab the
edges of the view and resize it like I did with the scrollview. In
some cases the edges disappear, but this is not entirely predictable.
What I discovered was that I had to set the auto-sizing bars to springs
on the inside of the scrollview AND on the inside of the view. This
allowed me to grow the view to the size that I need, move the objects
inside around, and add additional items to it. To get the scrollview
to scroll, I then had to change the springs of the view back to bars,
so that the view didn't resize itself when the enclosing scrollview's
size changed. This SORT OF makes sense.
After all that, the questions:
1. For getting a bunch of text fields and other items into a
scrollview, is this the "right" process, or did I construct a complex
solution to a problem with a simpler answer?
2. The scrollview works, but it starts at the bottom left of the view.
How can I make it start at the top right? And why would it default to
the bottom left anyway?
