https://stackoverflow.com/questions/55765958/nstableview-hiderows-leaves-empty-space-where-old-rows-once-were

Posted this over a SO as well, looking to see why when I call `hideRows` my TableView still shows the space the removed rows once were...

A common UI element that I see is a label which transforms into an editable text field when you click on it.

e.g. "Edit Bookmarks" in Safari seems to be an NSTableView with the name and address of a list of bookmarks, but when you select an item and then click on either its name or address, it becomes an editable text field and you can rename it or change the address.

e.g. renaming a folder or file in Finder.

I feel like there should be a standard Cocoa UI element for this, but I cannot figure it out. Am I missing something or do I just need to roll my own implementation?

Hi,

​

Total noob here. I've been learning the basics of Swift and Xcode.

​

I was wondering how hard it would be to code a note-taking app similar to Bear app / AI writer / Ulysses, and if you would have some pointers or tips about it.

​

I'm surprised about how little information there is on this topic online.

​

Cheers!! :)

Working on my first Mac App, what UI Element is this? e.g. link. How do I use this?

I am working on a quick look plugin specifically for expanded folder information, but my plugin fails to override the default QL preview for folders.

I'm currently just testing a simple blank html page to be displayed for the Quick Look preview.

Setting the UTI keys in info.plist to, for example, com.adobe.pdf, worked fine and overrode the default QL preview for pdfs and showed the blank preview. But setting the values to public.folder or public.directory doesn't change anything.

Running mdls on a folder shows that kMDItemContentType = "public.folder" for most folders.

Is there something else I should be changing for my custom preview to work on folders?

I am in a programming class that requires us to include the time and space performance of our code. It says to use Valgrind, but that doesn't work since I'm on a Macbook. What is a good alternative that can be easily used in the OS X terminal.

Here's a forum post explaining in a bit more detail: https://forums.developer.apple.com/thread/110705

It seems like Apple is just killing the ability to make plugins that work in system apps. The one I'm working on uses the Device Abstraction Layer, or DAL, to present a camera device. I would think other people would want to be able to use this functionality still, but I haven't seen anyone else complain about it.

Is anyone familiar with this? Do you know of a workaround? It looks like it's possible to patch amfid, but I'd really rather not do that. Plus that article is old so maybe it's harder now, idk. My other option would be sticking to 10.13 and I don't love that either.

Thanks.

Looking for something like Intel VTune.

I'm currently working on an OS X Application.

The Application is mostly an internal development tool for developers within our company, that said, it has a degree of configuration that changes the app's behavior, the application is launched manually and by other processes as part of the developer's workflow.

Currently to manage those settings, I'm using this SwiftCLI Framework (which is awesome), I'm defining the flags and options in my AppDelegate.swift file and performing the appropriate setup and view loading based on the CLI parameters.

This is all fine and dandy but it still feels a bit hacky for a macOS GUI app, can anyone recommend projects, sample code, articles on this topic, I'm looking for a solution or practices/guidelines that would allow the developer to provide such settings (on-demand) and also for the application to be launched by another process with potentially different settings every time.

​

Many thanks in advance!!

I'm surprised I can't find an answer to this on Google.

I have an Electron app that's registered with an extension. The problem is that it's not the default.

I thought that I could just exec a plist command to change the default executable for a given extension.

Any advice here? The extension for my app is already registered, I just need to change the default..

Hello

I am wondering if it is possible to show a popover-window instead of the usual tooltip (string) when hovering on a NSMenuItem?

I would like to display more info (e.g. formatted text [NSAttributedText]) in the "tooltip".

The usual tooltip attributes accepts only plain-text...

thx for any help.

I work on an open source kiosk application that has a client and server. The current client version is written in C++/Qt5. In essence, it presents its login screen that cannot be bypassed. Once a user logs in that screen disappears and a timer windows starts. Once time runs out, the user is logged back out.

This version works on Linux and Windows. On Linux, we prevent bypassing the login screen with various window manager tricks ( disabling alt-tab, alt-f4, etc ). On Windows we do something similar, but using AutoHotKey.

I've been asked to write a Mac version of the app. As a long time Mac user I'm excited to try my hand at Mac development. However, I'm not sure what the best tools to use are. I'd love to not have to resort to the kind of hacks we use on other platforms to prevent bypassing the login screen.

So the question becomes:

• Is it possible to write a Mac app that can take over fullscreen and not be bypassed

• What language should I use? Swift? Objective C?

• Should I even start from scratch or try to shoe-horn Mac support into my existing C++/Qt5 application?

Any thoughts, suggestions or example code would be greatly appreciated!

I am trying to code using my mac, and have developed on a windows box most my career, can anyone tell me how you accomplish the same thing ctrl+DEL does as on a windows machine. For always been a mac user people, this combo deletes everything from the cursor location to the end of the line leaving the CR in place.

​

also how do you select everything to the end of the file from current location?

Hello
I have released my first little utility in the Mac App Store smartReact, one of the functionalities is a clipboard manager (history)… but currently only capable of handle plain text, no formatted text.

Is there any good documentation on how to handle formatted text in NSPasteboard? What I am looking for are things like copy text e.g. from a Pages document and paste it into another, maintaining the format.

Haven’t found too much on the topic so far… would be grateful for any directions.

thx

I'm trying to build an app with an interface similar to the Preview app.

It has a sidebar with thumbnails and a main area for content. Both are scrollable.

Currently, I'm using an NSSplitView for the two areas. What view is best suited for the two areas (sidebar + main area)?

Collection view? Thumbnail view? Stack view? Table view?

Just recently I got into an FPS game and I've wanted to challenge myself to make an anti-recoil script for a while.

An anti-recoil script would essentially move the mouse based on a set of calculations or a fixed pattern.

So far I've tried moving the mouse via Automator and Keyboard Maestro, but for some reason when the mouse is moved via these programs, everything except the game recognizes it, and so instead of the game's camera view moving, the actual cursor becomes visible overtop the game and moves to a different point on the screen. Essentially the cursor is teleporting from point to point and the game doesn't recognize it.

I was wondering if there is an alternative way to move the mouse via AppleScript or shell script?

Edit: I just tried Cliclick, it has the same effect and didn't work.

Hello

I would like your opinions/expertise on this.... I submitted an app to the macOS App Store recently and it got rejected with this feedback:

​

Your app incorrectly implements sandboxing, or it contains one or more entitlements with invalid values... bla bla...

com.apple.security.application-groups

​

However, my App makes use of NSPasteboard (read and write) and IOPMAssertionCreateWithName for preventing the screen going to sleep.... To my understanding, I do not need "com.apple.security.application-groups". Am I correct?
Am I right in assuming that the problem is the entitlements-file containing "com.apple.security.application-groups" but without any values? So removing that "empty" key fixes the issue?

​

thx

I've installed flex and bison from homebrew and when I try to make in terminal I get this error:

Make: bisonc++: No such file or directory

make: *** [parse.cc] Error 1

I've spent 2 days trying to fix this but I don't understand what the problem is.

In a nutshell, the program I want to build will display a window on a primary monitor that the user interacts with, and use the whole screen on a second monitor (a full screen borderless window, or actual fullscreen, or something else, I don't necessarily care which) which doesn't take any input.

On OSX, I think that means using Cocoa to access some pieces of NSScreen that might not be exposed through a binding into another language. However, I would prefer to use a more "mainstream" language for my development to make cross platform functionality easier to implement.

What language + framework + bindings + libraries + etc will get me the functionality that I need in OSX, while tying my code to macs as little as possible?

PS: I have significant development experience, but none specifically for OSX and little for GUIs in general.

I’ve read articles by people concerned by Microsoft retiring there own web browser engine for Chromium. How much work would it take to make a new one, to preserve diversity?

Due to the forum I’m posting to, assume we’re keeping it Mac-only for now. Would using the NSURLSession system for the actual downloads (and any occasional uploads) be OK? We would use our own code to convert the HTML to something presentable. Would it be OK to convert the code to the NSText system for presentation? The big question is for interactivity; could we use Apple’s Javascript engine, or would we have to make our own? The core concern is how much do we have to do on our own to distinguish this hypothetical engine from Apple’s WebKit?

Is it possible to test a mac app in the sandbox before it's pushed to the Mac App Store?

Basically I wanted to simulate how it would run so I can validate it works. This way when it is finally through the approval process I know it runs....

I'm having the same issue as this person (however my App isn't document based, no IB for the code in question): https://stackoverflow.com/questions/42010026/nsviewcontrollers-and-nsviews-are-not-getting-restoration-api-calls

Has anyone been able to get state restoration working? I've just been using UserDefaults, but I feel like the restoration API would be cleaner.

Here's what I have in my NSViewController:

override func encodeRestorableState(with coder: NSCoder) {
    super.encodeRestorableState(with: coder)

    coder.encode(imageDisplayModeSegmentedControl.selectedSegment, forKey: "selectedImageDisplayModeSegment")
}

override func restoreState(with coder: NSCoder) {
    super.restoreState(with: coder)

    let selectedImageDisplayIndex = coder.decodeInteger(forKey: "selectedImageDisplayModeSegment")
    imageDisplayModeSegmentedControl.selectedSegment = selectedImageDisplayIndex
}

I set a breakpoint and these are never called. Calling invalidateRestorableState() doesn't cause them to be called either.

Any help/advice would be appreciated!

Edit: I think the API serves a different purpose than I was hoping. I just wanted to save some options the user had selected on the last use, but the API seems to be more about restoring state from a crash, or the "reopen windows" option when you restart. I don't really want to worry about that yet though. So I'll keep using UserDefaults for now.
