1. I usually create all my interfaces with InterfaceBuilder, but it
so happens that I have to make a piece of interface programmatically.
Somehow, after looking through Apple's docs for a few hours, I still
haven't figured out how to create a small version of a slider
programmatically. If anybody knows which is the right message to send
to NSSlider or NSSliderCell, this would make me very happy ;-)
As with all NSCell subclasses, NSSliderCell can be sent a
-setControlSize: message, passing "NSSmallControlSize" or
"NSMiniControlSize" to make it smaller than "NSRegularControlSize".
As with any NSControl subclass, you can get NSSlider's cell by
asking it for its -cell.
2. I use an NSSplitView in one of my windows. Somehow, when I resize
the window, the view behaves in a bizarre way (basically it doesn't
respect the values of constrainMaxCoordinate and
constrainMinCoordinate returned by the delegate). I also tried
implementing splitView:constrainSplitPosition:ofSubviewAt:, but it
doesn't get called when the window is resized. Of course I could
reset the split position in the window delegate, but this brings me
to the second question which is what is the correct message to send
to NSSplitView in order to change (and retrieve) the current split
position?
Take a look at NSSplitView's -splitView:resizeSubviewsWithOldSize:
delegate method. There are a number of examples on the web (GIYF) for
how to use this method to best suit your needs (like keeping a
Mail-like sidebar a constant size during window resizing, etc.).
I recommend downloading and using AppKiDo by Andy Lee. It's an
invaluable resource for not only browsing the documentation but
visualizing the Cocoa class hierarchy (a vital concept when using any
API).
