Code signing checking

Is there any API for doing the following activities related to code signing? - Check that the signature on the running codesigned executable is from the same company as the signature on a bundle? OR - Get the company from the codesigned running executable and - Get the company from a signature on

Are runtimes of system objects dynamic/SDK dependent/whatever?

I'm trying to understand how Mac OS X actually implements the predefined objects like NSApplication. Not in detail by function, but where the code lives. This is by way of understanding what happens if the SDK version doesn't match the system version. Let's suppose I would like to use an imaginary

Re: Problem with rangeOfString and Umlauts

This is largely from memory, so details might be wrong. Normalisation is an insufficiently known thing to consider when working with Unicode. (We all know that Unicode is a list of code points (integers). Here are some Unicode points for this discussion: U+0065 "e" Latin Small Letter E U+00E9

Re: Performance issue on macOS 10.15 obtaining display name for ~/Desktop, ~/Documents, and ~/Downloads

Your report is interesting. I have been following it but may have missed a part of the discussion, so here is one thought I had. You say that getting the display name of ~/Documents may result in a delay. This is localizable, so that in Portugal (for example) the display name is Documentos. So

Re: Not seeing rightMouseDown: - what are the docs actually saying ?

" Why are you compiling a plugin for 32 bits?" Because plug-ins must match the host app. In this case the host app's 64 bit version was only released 4 years ago. (The host app is made by a third party). Older versions of the app run on 10.14 and are still widely used by our customers. So, while

Not seeing rightMouseDown: - what are the docs actually saying ?

I believe I may be seeing an effect described in the Cocoa docs for the rightMouseDown: method. I am unsure exactly what the docs are saying however. Symptom: compiled for 64-bits, an unhandled rightMouseDown: is eventually sent to the NSWindow subclass, but compiled for 32-bits (and run on

Re: NSScrollView showing part of view with white space above

No auto-layout, identical coordinate systems. I found the solution, which is entirely my fault of course, thanks to your comment "It sounds like your NSView actually has white space at the top." For the benefit of future readers of this thread, here is the solution. I assumed the underlying

NSScrollView showing part of view with white space above

I have having a problem working with NSScrollView. The code is in pieces all over the desk at the moment, but I'm asking in case someone recognises the symptoms, before I reduce this to a simple test case. An NSScrollView is made from an NSView containing various NSControls. The NSView is fine

Is the question, what is canonical mapping? I'm going to assume it is, so I can share what I found when I hit much the same issue. This is mostly from memory so let's hope it's right. Take the word Café. How many Unicode characters is this and what are they? Turns out there are two answers. The

Re: why use extern "C"

This is common practice. Here's why. In C++ this #ifdef __cplusplus extern "C" { #endif ………./*some function,struct*/ #ifdef __cplusplus } #endif compiles as extern "C" { ………./*some function,struct*/ } As you identify, this declares C linkage, usually to a precompiled C library, or to make a

Almost certainly not the font itself. Looks like classic mojibake. The sequence which you seem to report, capital A circumflex, one-half might be in the encoding ISO-8859-1 (aka Windows-1252 aka informally Latin1). If so we have c2 - capital A circumflex bd - one half But what is the UTF-8 form

Re: PDF image template comes out too small

I've never used this API but perhaps the problem is that you are thinking of PDF pages as having a size in pixels. They absolutely do not, because they are a rich collection of text, multiresolution images and vector. The fact that your PDF pages might contain only a single resolution image is of

32-bit / 64-bit roadmap

So far as I can see, all recent Mac OS systems are 64-bit on 64-bit hardware and can run an app shipped in 64-bit only. And 32-bit continues to run fine. But what about the future? Perhaps we can only speculate about whether 32-bit apps will be deprecated, but maybe Apple have started to hint

Re: Bitmaps, colorspaces, etc.

I don't know anything about these methods. But in colour space work, "retagging" would usually mean changing the attached colour profile without changing the pixel values. For example, if an image starts as AppleRGB, it could be tagged as sRGB. This is not a conversion. The pixel values, numbers,

Re: Drawing many different strings quickly

I'd like to suggest a different approach if things cannot be tuned to have far fewer draw calls. Font caching etc. is very fast, but not as fast as it could be given the choices it has to support. I think you said you had one font, one size. I'm guessing you also have no more than 256 different

Localised alert/confirm message

I use NSAlert to display a dialog with OK/Cancel, and noticed this had (wrongly) not been localized in my code. However, I noticed some other things. From the spec, if I replace OK/Cancel with other text, the automatic assignment of keyboard shortcuts is not done. All of this can be fixed, but I'm

Edit menu localisation, default application menu

It turns out, and I'm sure this will surprise nobody but me, that for the copy/paste/cut keyboard commands to work in Cocoa my app needs to have a suitable Edit menu with copy/paste/cut menu items and keyboard equivalents. My question is about localisation. The app is localised via its own string

First responder (?) problem, and orphaned highlight boxes
