I am developing an Mac OS app, and have preference window presented as model. This works just fine as I want and I don't want to change that behaviour. The problem is: when the window is shown, and I debug on some breakpoints, the preference window is still there, however, Xcode's app is in focused now, but the preference window from the current app still shows on top. This is annoying. I have to drag it to somewhere to see the Xcode window. Is there anything that I can do so that if the app is in debug mode, then that preference window should also be gone away with my app in background and just Xcode is in foreground?
When a window is run as a modal window, its window level is set to NSModalPanelWindowLevel, which is above normal windows. As a hack just for debugging, you could do something like this just before running the window as modal:
dispatch_async(dispatch_get_main_queue(), ^{
NSApp.modalWindow.level = NSNormalWindowLevel;
});
Another approach would be to just run your app on a separate desktop space from Xcode.

I'm trying to write an accessibility app based on a "no-click" mouse concept. The idea is to capture mouse gestures that will be interpreted as clicks and pass the events to other apps. I have most of it working, except that I don't know how I could run it on top of fullscreen apps post Lion. Right now the app window is transparent and follows the mouse around, but this approach won't work with other "Desktops" or full screen apps, as the app stays in its current desktop when switching.
Any ideas?
What I needed was to call
[self setCollectionBehavior: NSWindowCollectionBehaviorCanJoinAllSpaces | NSWindowCollectionBehaviorFullScreenAuxiliary];
and also (important for the fullscreen apps!) set Application is agent (UIElement) to true in the info.plist file.
I'm working on a cross-platform command-line application (in C++ on
Win/Linux and ObjC++ on OSX) which sometimes creates an OpenGL
context. The OpenGL context and window creation code is obviously
different for the different platforms, but on OSX it's done through
NSOpenGLView and NSWindow. There's no nib, and it's not built with
Xcode (it uses a cross-platform build script).
On OSX, the window is created and works fine, but the OpenGL window
doesn't show up in the Application Switcher (Cmd-Tab). This means
that it's tricky to find the window if you 'lose it' behind other
windows, and can often only be found by going to Mission
Control/Expose.
My question is: is there a programmatic way (i.e. a message to send to
the NSWindow object or NSApplication) to ensure that a (unix-style)
command line application will show up in the Cmd-Tab list once the
window is created?
You need to transform the process from an accessory to a regular app. Call [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular].
Once you do that, though, the app will also have a menu bar when it's active. This is good because it's what users expect. However, you probably need to add appropriate items to the menus in that menu bar to get a decent user experience.
Your app will appear in the Dock as well as the Command-Tab application switcher. By default, an unbundled executable will get an icon that looks like a CRT display showing the word "exec". You can use [NSApp setApplicationIconImage:someImage] to set a better icon, although the Dock will revert to showing the generic executable icon briefly as the process exits.
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 have a foreground application that shows a NSStatusItem along with a menu (via NSStatusItem setMenu:(NSMenu *)menu). However, this menu does not display when I am looking at another app in fullscreen mode (say Safari) in Lion.
I know that I can make it work by setting NSBGOnly to true in the Info.plist file (or NSUIElement), but both methods will make my app icon disappear from the task switcher as well as hide the main menu once I manage to focus my app.
Finally, I have tried setting NSUIElement to true and do the following in my app upon startup (see also How to hide the Dock icon):
ProcessSerialNumber psn = { 0, kCurrentProcess };
TransformProcessType(&psn, kProcessTransformToForegroundApplication);
This made the menubar appear again as well as the dock icon but the original problem (status item menu does not show up in another fullscreen app) is visible again. Whatever I try, I can't win.
Any suggestions would be highly appreciated!
Unfortunately I think this is expected behaviour. Your app is considered a foreground app, so all its UI is disabled while another app is in full screen. You should file a bug if you feel that status items in foreground apps should still be available to other apps in full screen mode.
Probably the best solution would be to split your app into two parts, an agent app which has LSUIElement set to true, which creates and manages the status item and its menu, and your main foreground app which does most of the work and which launches and manages the agent app.
There are a variety of inter-process communication methods that you can use to get the two apps talking to each other, such as Distributed Objects or Apple Events.
I was surprised this doesn't happen automatically, but I would like my applications window to be in focus as I click its dock icon, when in minimized mode.
Just to clarify, when I minimize the app, the window goes to dock, but when I click the its corresponding Dock Icon, the window don't come in focus.
Is there anything I am missing?
I am using Qt 4.5.3 on Mac OS X 10.5, 10.6
Thanks for help.

First answer: That's the expected behavior of a Mac app. Try Safari for example. An app can be active without showing any window. In that case, only the menu bar at the top shows that the active app is changed. So, unless absolutely necessary, you shouldn't bring the minimized window back unless the user explicitly does so. That's the Mac way!
Second answer: I understand that there are cases where you want to bring the minimized window up. In Cocoa, the application delegate method -applicationDidBicomeActive is called when the application gets the focus, and there you can bring the window up yourself. I'm sure Qt also has a similar event/callback/signal or whatever, but I don't know any Qt ... :p Sorry I can't be of any help.
