I know this is a noob question but I do not know where to look. I come for a
Java background. So I know what to do there, but I look at Cocoa and I have no
clue where to start since the object model is quite a bit different.
Should I create a sub-class of NSControl or do something else?
I want to have a bunch of icons (like the Finder images including the text
underneath it) in a window. These would be used to traverse a hierarchy of
objects (i.e. double click and it shows another list of icons). Originally, I
was going to implement this all in my NSView class. But I was thinking that this
does not seem to be the correct way implementing it.
I looked and found something about "Subclassing NSControl" (URL:
http://developer.apple.com/documentation/Cocoa/Conceptual/ControlCell/Tasks/SubclassingNSControl.html
) but I am not sure if this is the correct approach. If so, what are the methods
I need to override to make sure that the size is maintained? The
control/component will need to react to mouse clicks but the NSView will be
handling the dragging of the position of this control/component.
