nsbox | A powerful pet container manager | Continuous Deployment library

I working with swift 4 for macOS and I would like to hide an stack view item with animation.

I tried this:

I am writing an OSX app with Xcode. It consists of 1 Window controller which contains view of View Controller. Window Controller and View Controller are linked each other through a Relationship "window content" to "View Controller".

ViewController has 1 NSView as it's view, and it contains NSSplitView and NSBox as it's children.

This app works fine on Xcode, and show view really well when I run it on Xcode.

But after I archived it, and export on Xcode Organizer, The app doesn't show any content, it only shows ToolBar.

Is there a system-defined NSColor for the background of an NSBox? Testing shows it to be RGB (226, 226, 226) but there does not seem to be anything like controlBackgroundColor for it to easily switch when in Dark Mode. I am using this color for the background of a custom NSView and don't really want to embed the view in an NSBox to get the effect I want.

Trying to use a NSBox to get a background color which works with dark mode, it behaves differently than a NSView.

The NSBox is created in Interface Builder, and doesn't work with Auto Layout. It is not resizing any child views.

• Xcode 9.2
• macOS High Sierra (10.13.3)

macOS gives users a choice to "increase contrast".

I am trying to support this within a macOS app. Specifically, I want to adjust the fill of NSBox

What's the way to do it?

Update

There is a NSWorkspace.accessibilityDisplayOptionsDidChangeNotification notification however, it doesn't appear to fire.

Sample Project

I’m new to Cocoa and am trying to create a very simple keynote clone.

For my slides, in the detail view, I use an NSStackView comprised of Textfields set with NSAttributedString. This part works pretty well.

My master section is where I have problems.

I thought I could clone a “slide” View using archive/unarchive, add all the slides to an NSStaxkView and then somehow scale down the sidebar (master) slides.

Problems I have:
1) for the life of me I can’t figure out how to scale the view down to 10% size.
2) I tried using NSBox to create the “card” effect in the sidebar that keynote uses, but am unable to render the view content inside an NSBox for some reason.

Am I going about the architecture all wrong? Any general guidance? I’m currently reading through https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/CocoaBindings/Tasks/masterdetail.html

I'm using a NSPopover for my menubar application and it seems that its default aqua theme (and also light and dark) paints it with a semi-transparent background.

I want an opaque background.

So I searched SO and found I can set a background color for the contentViewController like so:

My app needs to select a given filename from a list of filenames presented by iTunes' "Import Playlist" dialog. According to Accessibility Inspector the majority of the list's parent have no description and one item is described as an "NSBox". MY SPECIFIC PROBLEM IS THAT TRYING TO REFER TO THE "[NSBox]" AS "group 1" FAILS WITH THE RUNTIME ERROR ESSENTIALLY SAYING THE NUMBER IS TOO LARGE?!

This is a near identical situation to my earlier question How do I refer to an object in a window whose Accessibility Inspector description is " (group) [NSBox]" in Applescript? for which the only answer presented an alternate method of accomplishing my specific task at the time.

The list item marked with a * rather than a - is the actual item I had selected in Accessibility Inspector. The full hierarchy of the specific item I need to select in one example case is:
