Re: initWithFrame not being called on my NSImageView subclass



OK, sounds like I'm not out of the woods.

Here's the trouble: I have some controls ( in my toolbar ) controlling a couple properties of the image view subclass. Specifically, a zoom factor and a tiling mode ( this is just a quick-dirty app for viewing compressed DDS textures. I've already written a quicklook plugin and an NSCustomBitmapImageRep so the plumbing's all there ).

When I assign a default tiling mode and zoom factor in awakeFromNib, for some reason it doesn't "propagate" to the bindings.

NSLogging the order of events, I see something like this:

1) new document is opened from a DDS file:
2) TilingImageView is asked for a scaling factor. _scale is zero so it returns zero
3) awakeFromNib is called. I call setScale: 1
4) Nothing. My slider's still showing zero.


Now, my slider does work: Dragging it changes the scaling factor. But for some reason calling [self setScale: 1] in awakeFromNib doesn't notify the slider in my toolbar.

This is why I'm trying to find a way to make certain _scale = 1 before bindings queries my image view instance.

If the view's being loaded from a nib it's archived, so you need -

I'm not sure -initWithCoder: is guaranteed to be called, and is certainly not the "proper" place to be performing object initialization after awaking from a nib. The official recommendation is to either create an IB plugin so that your version of -initWithFrame: is called at design time, or perform subclass-specific initialization in -awakeFromNib.
