Hi all, For a custom UI I’ve had to write a custom control deriving from NSButton, which highlights itself in a special way on mouse-over. In the method which does the highlighting, I check if the button’s state is either .on or .off, so I know which title or alternateTitle to display. But I r

capturing the content of a SpriteKit SKView (or SKScene, SKNode) to an NSImage ?

Hi, Has anyone tried and succeeded in capturing the contents of an SKView to an NSImage ? Techniques working for a regular NSView won't work apparently because an SKView is based on OpenGL. I tried taking advantage of the fact that an SKScene is an SKEffectNode and used a custom CIFilter which

CoreData and undo/redo : how to add a managed object with attributes already set in the undo/redo stack ?

Hi all, I'm having difficulties with the undo/redo mechanism and my Core Data objects. The problem is that I create a CoreData object (say a rectangle), then set some of its attributes according to some controls values (the position and size of a CALayer the user has just created in a view). Th

example of a NSScrollView where scrolling is overridden ?

OK this isn't very clear so I'll try to explain my problem. I need to scroll over a potentially very large area, that area has CALayers, which will themselves "be" very large. That is, they will appear so. So I need to have control over the scrolling so that those "large" CALayers will appear t

Storing UInt64 in a Core Data attribute ?

Hi all, Apparently, Core Data only handles signed int types for attributes. I need to store UInt64 ones (MIDITimeStamp, more precisely), and to show these in a table column. Of course the displayed values are signed, some negative some not. Google didn't bring anything useful on that topi

Referencing a controller from one NIB to another ?

several windows in a NIB ?

Hi all, I'm in the process of writing a proof-of-concept music sequencer. At the moment all I'm aiming for is putting note events into tracks. I'm using a Core Data model, which defines a Composition holding multiple Tracks, each holding multiple Events. I've already done a basic NIB for

Hi, I'm currently toying with the idea of writing a very basic music sequencer. The main window would, like all sequencers, display a list of music tracks (e.g. Garage Band's main window). Apparently, an NSTableView with two columns (one for the track's various parameters and the other fo
