I'm writing an app that should remain visible on the desktop at all times. As such, I have to prevent other apps' windows moving on top of my app's window.
The Dock.app from Mac OS X partially does this: if you resize windows, they won't resize into the Dock.app's screen space, and if you hit the windows' '+' button, the window will not cover the dock.
Is it possible to replicate this functionality, and if so, how can I do it?
I'm not sure how well it will work and it definitely requires "Enable access for assistive devices" to be enabled in the "Universal Access" system preference panel, but you could try using the Accessibility Hierarchy to monitor window frame changes of all on-screen windows and further manipulate them as desired.

How can I configure PhpStorm to use the "non-native" fullscreen mode? I'd like PhpStorm to be fullscreen (without the macOS top menu bar, etc), in the same window (without creating a new window that I have to scroll between).
The terminal for macOS iTerm2 have this setting. You can choose to remove the tick from "Native full screen windows". When this tick is removed, the fullscreen mode will simply take out all space in the window, without creating a new separate window.
Native fullscreen example
Notice how a new separate "window" is created called "PhpStorm"
Non-native fullscreen example
Notice how theres still one window called "Desktop". The iTerm window fills out the whole screen though.
the only way you can do it at the moment is by adjusting the dock in mac to hide menu automatically and then spread the editor to wider and higher setting
click right on the dock in mac and goto settings and hide menu works for me
i am suffering from same issue lol after i saw iterm2 :P
Background
We are building a cross-platform application with "popup" reminders, they are custom windows/dialogs which uses QWidget.setWindowFlags like this:
self.setWindowFlags(
QtCore.Qt.Dialog
| QtCore.Qt.WindowStaysOnTopHint
| QtCore.Qt.FramelessWindowHint
)
These popups show up on the systems we have tested (MacOS, Lubuntu (LXDE)), even when we switch between different virtual desktops the dialogs are still shown in the current desktop. However:
Problem
When the user is in fullscreen mode on MacOS (Sierra 10.12.6) the dialog instead is shown in the last virtual desktop that was used
Question
How can we show our "popup" dialogs to the user even when the user is in fullscreen mode on MacOS?
The short answer is that you can't and neither can any other app.
Here's why.
The idea is that when you select the fullscreen view for an app, you want to focus exclusively on that app, to the exclusion of all others. So the app not only expands to fill the entire screen, it removes the menu bar and creates its own desktop space.
You can see how this works using Mission Control (by default, swipe up with 3 fingers). You will see all the apps and all the desktops across all your monitors. Next, set an app to full screen and swipe up again. You'll see that the app has a dedicated desktop (which I believe doesn't even have wallpaper).
The bottom line is that macOS fullscreen view does not support pop-ups.
my mac os application is running in full screen mode.
On button click i'm opening finder window which allow me to open any another file or application but problem is that, when i open any another app, screen switches back to xCode and that application opens. Need to open selected app/file above same window.
I have tried:
**[[NSWorkspace sharedWorkspace] launchApplication:path];**
passing application path to launchAppication method
How can i do this?????

The issue is basically because using [NSView enterFullScreenMode:withOption:] will set the app's [NSWindow level] to kCGMaximumWindowLevel - 1, so that all other app's windows will appear behind it.
This is kinda what you would expect from a fullscreen app, which implies system-modal behaviour.
I guess the only way of allowing another app to appear in front of the fullscreen app would be to lower the window level, however I have no idea what effect that would have.
I am trying to build an Adobe AIR app that runs on two monitors with an extended desktop. Is that possible?
I've read fullscreen is restricted to a single display and the only option is to maximize the app to both displays. Is that right? If so, how can I hide OSX top menu bar?
Just for the record, OSX does not allow you to have more than one full screen applications (of any kind, not just AIR) open at the same time nor it let's you to expand a full screen app to more than one display.
An application window can span multiple displays as long as the window is sized properly. Menubar and dock can also be hidden. Check NSWindow in the apple documentation for more info. Adobe may or may not support this feature.
My Cocoa app displays a transparent window on the screen, but when the user tries to take a screenshot using Mac OS X's built-in screen capture key with the option of selecting full windows (Command-Shift-4, then Space Bar), my window gets highlighted as part of the possible windows to capture.
How can I tell my Window or App not to allow this? My Window already refuses to be the Main Window or Key Window through -canBecomeKeyWindow and -canBecomeMainWindow both returning NO, but this still happens.
The Window is also at the NSModalPanelWindowLevel and NSScreenSaverWindowLevel does the same thing.
Notice that every window is eligible for screenshots, even the desktop, dock and menu bar, which are special windows. You can even take a screenshot of the Exposé overlay window itself. This leads me to believe that there is no way to do this.
I suppose you could hook the Command+Shift+4 key event and hide the window, but that key combo is user-definable, so it is subject to change.
