“column”

Hmm even though you cannot adjust the space in IB for the area where column titles go, coming out of Interface builder, if I resize the window, column titles suddenly shows up.

Thanks for replying. I have to apologize - I was a little rushed when I wrote all that and mistakenly mentioned -drawRect:. I've actually just solved the two main issues I was having. Here's a post-mortem:My model object (Figure) does its own drawing (with lots of caching mechanisms) and its resulting image is used by an NSImageView on screen, and its PDF data is provided for export. Essentially, what I've discovered is that the low resolution is expected when using -lock/unlockFocus on NSImage instances. The correct behavior, which I somehow missed in the documentation the last time I visited this problem (and for a few hours this time), is to add an NSPDFImageRep to the image manually. This has resolved my resolution problem using the newer drawing handler method.I solved the render it now, please issue by immediately caching the PDF data for the image (which my Figure class holds as a property now vs. an on-demand method) alongside the image itself (dumping both when the figure is invalidated and its cache

So the issue with vmtracker is that it polls the system. Due to this, it can miss spikes. I bet what is happening is that something is mapping a large amount of memory into your process. Perhaps the kernel. Also the memory could be compressed out of your process so it doesn't appear in the dirty column.

Its tables with numbers in format 00.00 or 0.00000 200-300 rowsabout 100 columns It’s a reference table, to get correct value by column and row nameAs an example, here is multiply table 1 2 31 1 2 32 2 4 33 3 6 9So, basically, to calculate some values, I need to get reference value from one or two tables.For examplex = (a+b+c)/(get value from table A for 2*3)

Is the table rectangular? That is, does each row have the same number of columns? And vice versa?Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail = eskimo + 1 + @apple.com

Yes, it isEach row have the same number of columns, and vice versa, yes. real one will be similar with this - https://sanctusaura.files.wordpress.com/2010/06/relative-humidity2.jpg

300 (rows) * 100 (columns) * 8 (size of double) = 240000 bytes = 234K. I think most people take up more space than that for icons on buttons.

If you downloaded older OS versions from the Mac App Store in the past, you can redownload them by going to the Mac App Store and clicking the Purchased button. You can also find older OS versions on Apple's developer site (developer.apple.com). Click the Downloads link at the bottom of the page. It's in the Develop column of links.If you find supporting old OS versions annoying, drop 10.10 support. Many developers officially support only the latest OS version (currently 10.12) and the previous version (currently 10.11). Anyone running 10.10 can upgrade to 10.11 or 10.12 for free.

Replied yesterday, but it still on moderation because of link to picture with table example.So yes, all tables is rectangular, and each row have the same number of columns, and vice versa, yes.

But this will be considerably bigger if you put it in an XML plist.@DenisO, For a rectangular array like this I’d probably put the data into a file in binary form and then memory map that. You can then access the values at random and the VM subsystem will take care of the rest.Furthermore, I’d wrap this in a nice, Swift-friendly data structure. Something like this:class DataMap { let rowCount = 16 let columnCount = 16 init?(file: URL) { guard let d = try? NSData(contentsOf: file, options: [.alwaysMapped]) else { return nil } guard d.length == (self.rowCount * self.columnCount * MemoryLayout<Double>.size) else { return nil } self.data = d let base = d.bytes.assumingMemoryBound(to: Double.self) self.buffer = UnsafeBufferPointer(start: base, count: d.length) } private let data: NSData private let buffer: UnsafeBufferPointer<Double> subscript (row: Int, column: Int) -> Double { precondition((0..&

I found long ago that in Mac OS X 10.7 (Lion), you must set the Titled property of NSBrowser in Interface Builder; setting it in code in -awakeFromNib instead caused the column titles to disappear when the browser view was scrolled left or right. I haven't changed the code in my application since, because it works, so I don't know whether this problem still exists in more recent releases of macOS.
